Hyundai Tucson 2019

The contact's daughter owns a 2019 Hyundai Tucson. The contact stated that his daughter had parked the vehicle and left it unattended while in the on position. After approximately 10-15 minutes, the daughter attempted to shut off the vehicle by turning the ignition key from the front passenger side, but after powering off the vehicle rolled backwards down the driveway, also dragging the daughter. While rolling backwards, the front passenger door hit the concrete mail box, and the vehicle continued to roll across the street before stopping in the neighbor's yard. During the incident, the daughter attempted to activate the emergency brake, but was unsuccessful. As a result, the daughter sustained several bruises to the right leg/knee and the back area, which did not require medical treatment. The passenger side door and the concrete mail box were damaged. The police were called to the scene, but no report was filed. The cause of the failure was not determined. The manufacturer and local dealer were not yet notified of the incident. The failure mileage was unknown.

The contact owned a 2019 Hyundai Tucson. The contact stated that while the contact's wife was driving and parking the vehicle, the contact's wife depressed the brake pedal and the service brakes were inoperable. In addition, the contact stated that the anti collision braking system was inoperable and did not function as intended. The contact stated that due to the failure, the vehicle crashed into several oversize planters in the parking lot. In addition, the vehicle crashed into a wooden fence and then crashed into a tree. The contact's seventeen-year-old granddaughter was seated in the front passenger seat of the vehicle. The fire department and the police arrived on the scene. A police report and fire report were filed. The vehicle was towed to a local tow yard. The contact's granddaughter sustained a concussion and currently suffers from headaches. The contact's wife sustained an injury to the mouth due to the deployment of the air bag. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 27,000.

While driving, the check engine light began flashing and the vehicle shook severely due to engine misfiring. The vehicle has had a recurring cylinder 3 misfire throughout ownership. Spark plugs and ignition coils were first replaced around 40,000 miles and replaced again in December 2025 for the same recurring issue. A Hyundai dealership inspected the vehicle and found codes P0300 random misfire and P0303 cylinder 3 misfire. The dealership technician documented that the piston rings did not look good and confirmed the catalytic converter was damaged as a result of the misfires. The vehicle has had an engine rattle at idle, oil consumption, and blow-by since early in ownership. The engine defect is progressive and predates the current mileage. The flashing check engine light and severe shaking while driving at highway speeds created an unsafe condition with other vehicles on the road. The problem has been confirmed by a Hyundai dealership. Hyundai Motor America was contacted and denied goodwill warranty assistance. The vehicle is available for inspection upon request.

I helped my daughter buy a used 2019 Hyundai Tuscon with 42K miles since she was going to med school and needed reliable transportation. At 62K miles the engine failed. The engine stalled in the middle of the highway and she was in the middle of the highway for some time before she could restart the engine. She was nearly rear ended. The dealer she brought the car back to said there was no oil in the engine despite the fact that she had the oil changed two months before this incident. There have been many problems with the Hyundai "Theta II" and 2 liter GDI engines that were supposedly fixed and there was a class action lawsuit on Hyundai Tuscons up to 2016 which was well publicized. This car has a 2 liter engine (which is all I know). It does not appear that Hyundai has fixed their engine problems since I believe this is the same problem as before. I am filing this complaint in my daughetrs behalf since she has to take her medical boards in one month. It is bad enough that her car has been tied up for 3 months and she has to transport her husband across town twice a day.

The contact owns a 2019 Hyundai Tucson. The contact stated that while his wife was driving at low speeds, pulling into a parking spot on an incline, the vehicle accelerated and failed to stop. Then the vehicle traveled through several 15-gallon pots with trees, a patio, elliptical machines, and a wooden fence. The driver veered to the left, went down a mountain approximately 30 feet, continued down the hill, and crashed into a pine tree where it came to a halt. The occupant in the front passenger seat sustained a concussion. The driver sustained injuries to her lip and medical attention was provided. There were no warning lights illuminated. The vehicle was towed to the police station. A police report was filed. There was no reported fire. The driver's side front and passenger side front air bags were deployed. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, who provided claim number 21135585, and had the vehicle inspected but indicated the brake pedal had not been depressed but no additional assistance was provided. The failure mileage was approximately 27,000.

While driving, my vehicle stopped moving forward and the engine light came on. I pulled over and called for a tow. The service department at the dealership the vehicle was towed to said that the vehicle had less than a quart of oil in it. I just had the vehicle serviced 2 months prior. The service department changed the oil, oil filter and air filter. They drove the car and heard knocking. They found the rod bearing to be bad. They said it needed a new engine. The vehicle has approximately 51,000 miles. I never had any issues prior to that day. The car manufacture is refusing to replace the engine because I am not the original owner, not because the engine isn't defective. This is a 2019 Hyundai Tuscon with engine 2.0L L4 DOHC 16V. I believe there is a known problem with this engine, but the manufacturer doesn't want to admit to anything, nor do they want to resolve the issue. My vehicle could have caught fire. I could have been in an accident. I just want the car company to replace the engine without any cost to me. I would even pay for the labor, but they need to pay for the engine and any parts or tests that come with replacing an engine.

The vehicle was restarted and was pulled over to the side of the road and the vehicle stalled. The vehicle was towed to a dealer where it was diagnosed and determined that the engine block needed to be replaced. The contact stated that there was ice built up underneath the tires, and an unknown ring was replaced. The vehicle was repaired, but the vehicle reversed inadvertently while parked and stalled while driving at various speeds, and the vehicle failed to accelerate as intended, and the vehicle was shaking abnormally on several occasions. The vehicle was taken to the same dealer but was not diagnosed; however, the contact was notified that the failure might be associated with the catalytic converter. The manufacturer was notified of the failure. The failure mileage was approximately 60,000.

My 2019 Tucson has been getting horrible gas mileage and also making some strange noises that I'm unsure of what they are. It's also acting like it has no power installing on a pretty regular basis since the dealership has stated nothing's wrong with it and my vehicle health report continues to state nothing is wrong I decided to get a OBD2 adapter to place on it so I could see what was happening. While the vehicle is running at idle doesn't matter if it is cold or warm the throttle body sensor does not go under a 10 so it's obviously sticking I don't know if it is defective or if it's been like that for some time but if the throttle body is stuck then that's going to cause it to stall that's going to make it burn more gas that's going to make it run pretty crappy and be kind of hit and miss. The vehicle's brakes are always grinding and squealing. There is also a wine and a tapping clicking sound coming from under the hood I don't know if it's a bad pulley or bearing or a loose heat shield or whatever but it's not injectors there's something under it. The rpms are continuously getting stuck the gauges are getting stuck, this car malfunctions every day.

Driving on highways or interstates with the adaptive cruise control is when this happens. The first time I was driving on a sweeping left turn and coming up fast on a truck in the slow lane I was driving in, so I put on my blinker and made a quick lane change into the fast lane to get in front of another car in the fast lane behind me. Immediately as I was getting closer to the truck to pass it - suddenly my car put on its brakes to avoid a collision with the truck since the system was sensing the truck was in my path on the sweeping left turn. Fortunately the car behind me in the fast lane with me did not rear end me. This is just one of many times my car mistakes other cars as a danger and will brake. If I pull in behind a car that just passed me - brake! If a car is turning right and slows down at the intersection and is making the turn - even though I would never hit it -brake! This is supposed to be a safety item - but so far just is so overcautious I am surprised I have not been rear ended so far. I do not use the cruise control as much as I did when I first got the car. I turn it off now to avoid situations that cause the inadvertent braking.

My car is burning oil like crazy, having to top off engine with 1.5 quarts between 5,000 mile oil change with synthetic oil. Took to Hyundai for oil consumption test. Let them know I'm having issues with burning oil, and my check engine light comes on often. They looked at my car saw enough of a problem according to advisor to skip first step of oil consumption test and jump straight to step 2 an engine combustion cleaning, which cause multiple more codes to come on. Drove the 1,000 mile 1378 to be exact because I explained to them that I couldn't bring back at exact mileage and was told that was fine. I was toldy car was only a quart low and that that meant everything was fine and that they would now honor the warranty. I am using in ungodly amount of gas and my engine oil smells like straight gasoline. I explained this to the manager and he said he resubmitted to try to retest again and was denied. I do not know what to do at this point. The advisor even said he didn't agree with their decision but it was up to them. His hands were tied. I am a single mother still paying on the car and only bought new because of the warranty. I provided immaculate proof of oil changes and maintenance. Please help .

I was driving approx 55mph on [XXX] in my 2019 hyundai tucson when the check engine light came on and the engine started to stall. I felt the acceleration dying down in the middle of busy highway traffic. Gray smoke started coming from the hood cracks. I luckily was in the right lane already, so when I could I veered off to the shoulder and the car quit. The smoke was increasing badly. Ppl from the highway were yelling its going to blow up get away from it! I was so scared. I grabbed my phone and keys and ran as far as I could while dialing 911. Within a couple minutes flames were swallowing the entire engine and front of the car. I am furious. I researched online and hyundai has had many similar incidents with this car and other with this engine ! These need to be banned and taken off the road before they kill anyone else. Ppl have been injured and killed from similar situations just like mine. I thank God I made it out of this horrific situation alive. But now I have no car and am at risk of losing my job and then housing . I thought I would have this car for years. Now I'm traumatized and without transportation.

I was driving on the highway. The engine began making a ticking noise that momentarily went away and then quickly got louder. I saw white smoke out of the back, pulled over, and then saw black smoke from the front. The check engine light only momentarily came out AFTER the white smoke was visible and I was actively pulling over. I ran out of the car, and turned to look only to see a fire under the engine bay. I did not have a collision nor hit anything on the road. Engine had full synthetic oil in it, and the oil was changed less than 10,000 miles precious. (Also checked oil level/condition the week before). The car went from driving fine, to entirely engulfed in flames within 2-4 minutes. Maine state police: case# 245000657 The vehicle has not been inspected by the insurance company yet. The report will be sent to me, and it is currently available for inspection upon request. I literally could have burned alive. My family could have been trapped. I was on the highway, LUCKILY I decided to pull over when I did. If I did not, within 40 seconds I would’ve been engulfed in flames. I have most certainly not been sleeping well in the least bit. The only warning sign happened 5-10 seconds before I was out of the vehicle.

The contact owns a 2019 Hyundai Tucson. The contact stated that the vehicle had been experiencing excessive oil consumption, and the check engine warning light was intermittently illuminated. The contact stated that while driving 25-30 MPH, the vehicle was shuddering. The contact continued driving uphill, and the vehicle experienced reduced power and was driving sluggishly. The contact stated that after coming to a complete stop at the traffic light, the contact depressed the brake pedal firmly out of fear that the vehicle would roll backwards. The vehicle was taken to Valvoline, where oil was added to the vehicle. The vehicle was then taken to Firestone, where diagnostic trouble codes P0420, P000A, and P050A were retrieved. The contact was referred to the dealer for assistance. The vehicle was taken to the dealer, where the same diagnostic trouble codes were retrieved. The dealer recommended an intake manifold replacement; however, the dealer informed the contact that there was no guarantee that the repair would correct the failure. The vehicle was not repaired. The manufacturer was notified of the failure and offered the cover fifty percent of the repair cost. A case was filed. The failure mileage was approximately 103,000.

On March 21st, while driving my Hyundai vehicle, I noticed the vehicle began making a ticking sound. After stopping the vehicle, it slowly began catching on fire. The fire ultimately spread and resulted in the vehicle becoming a total loss. This created a serious safety concern and placed me at risk. I later learned there was a recall associated with the vehicle. However, I never received any recall notices because Hyundai reportedly had the wrong address on file. Had I been properly notified of the recall and potential safety risks, I would have done everything in my power to ensure the vehicle was inspected, repaired, and safe to drive. Because I was unaware of the recall issue, the vehicle continued to be operated without my knowledge of the potential danger. The incident caused significant financial and transportation hardship, including loss of reliable transportation and additional financial strain. Hyundai later reached a determination regarding the matter, but I remain concerned about the serious safety risk and the fact that I did not receive proper recall notification before the incident occurred. I am submitting this complaint because I believe the recall notification process and handling of this matter should be reviewed further due to the serious safety risk involved.

Our Tucson was stolen in Charlotte, NC on [XXX]. The pax rear window was broken and the thieves broke open the steering column to start the car. It appears they used the well-known "Tik-Tok" method. I have record that our Tucson had the "software update" installed, at a local dealership, a year ago. This update (which should've been a recall) was supposed to address this issue. Despite this update, the car was stolen in less than 2 minutes (I have Ring camera pictures with timestamps). I have doubts now that the dealership actually did the update. Part of the update includes a specific window sticker that is to be applied to the driver's door window. That decal is missing. There is no evidence that it was ever there (I have pictures). The car was recovered but cannot be driven. It must be towed due to the damage. Another concern is the engine and drive train. Criminals were out joy riding in our stolen car on an almost full tank of gas. Because the car cannot be driven, I don't know if there is any damage to any part(s) of the drive train. We are now waiting for our insurance company to arrange to have the car repaired. I am very concerned now about the long term viability and reliability of this car.

I have been trying to take care of this open and dangerous recall to the ABS braking system since August 20, 2020. I have contacted the dealership several times regarding the parts for this recall and have been told that they are still on back order. I just heard yesterday that Hyundai is recommending to park the vehicle outside due to a possible risk of the car catching fire. This to me is an important recall that I have been trying to fix for the last 5 months but have not been able to due to the parts not being available. I have contacted the Hyundai dealer where I purchased the vehicle today and they told me they do not have a time frame as to when the parts would be available or when they would be receiving them. This is completely unacceptable and Hyundai needs to be held accountable for not being able to have these crucial parts for a braking system available for the last 5 months for myself and for the countless other costumers who are probably waiting even longer. They do not have a problem selling/leasing you a vehicle and taking a payment every month and it seems like they don't value a life since they could cause a vehicle fire. Hyundai needs to be held accountable for this and should be assessed a fine for everyday day over the required time by law that they had to fix the issue.

I bought this 2019 Hyundai Tucson Sport new in May of 2019. I now have 9,000 miles on it. The vehicle suffers from constant hesitation issues when accelerating. This occurs from a dead stop, while turning, and while trying to quickly speed up to avoid a crash. It is like the fuel has been momentarily shut off. This is extremely unsafe. We have avoided several near-crashes through sheer luck in the past couple of months. This is the 2.4 engine and 6 speed auto/shift able transmission. If I put the mode to Sport, it helps some. To avoid the dangerous lag of approximately 2 seconds, the car has to be driven in manual mode. When the car is standing still at the light, everything appears normal. But as the light changes and I accelerate, it will suddenly "stall" for about two seconds, then it will speed up. It is like the engine is having trouble communicating with the transmission. I have called several dealers and they say there is no fix. Numerous other owners of these vehicles are making the same complaint. I do not want a new vehicle. I already have one. I just want it fixed before someone gets killed. Please review all the consumers complaints on this Hyundai Tucson. I also rented a vehicle for a day and it was a 2018 Hyundai Tucson. It did the exact same thing. This is extremely dangerous. Thank you.

My 2019 Hyundai Tucson repeatedly shuts off while driving , without any warning. It rolls backwards while in park. The car could easily hit me taking things out of the trunk or hit my neighbors walking past my drive. The car has no power. It can’t get up to speed. It shakes and I have to get someone to add oil to it frequently. The first time this happened was in April of 2023. The engine seized up and it was towed to Driver’s Village in Cicero, NY. They replaced the engine block. But not the converter. Now, it is happening again. I have had 2 diagnostic tests done. One by my mechanic and the other by Advanced Auto Parts. Both tests say that the problem is the catalytic converter, but Hyundai refuses to fix the problem and will not honor my extended warranty. I have written and called them numerous times for almost 2 years now, about this and they say they will call me back, but they do not. None of the dealerships will even look at my car. I need someone to look at my vehicle. This vehicle is not safe. Other Tucson owners have the same problems with their cars, that I am complaining about. There is a federal emissions warranty that Hyundai claim they have never heard of, that would fix my car and make it safe to drive. I just want Hyundai to stand behind their warranty and fix my car before it kills someone.

While driving down a busy road at 10:00 pm on New Years Eve, my vehicle's engine completely shut off. Immediately prior to the shut off, the vehicle's dash displayed the oil and battery lights. The vehicle's automatic emergency brake and steering wheel lock were both engaged, not allowing me (or the tow truck company) to move my vehicle out of this busy road. My car remained in this location for 3 and a half hours. The hazard lights stopped working after the first hour, making it extremely difficult to see that the vehicle was stopped. After the second hour, an officer parked behind my vehicle with their lights flashing as he said it was an extremely dangerous situation and my car was sure to be hit. He was able to get a tow truck to me before Hyundai. For hours, numerous people were forced to brake quickly/swerve into other lane to avoid hitting my car. This occurred right before an intersection, putting 4 directions of drivers at risk of collision. I stood in the rain, near my car, attempting to help direct drivers away from the lane until the police officer showed up. The vehicle is now at the dealership which confirmed engine failure, pending replacement. Possibly related, this vehicle had the catalytic convertor replaced 3 months prior. It is not yet confirmed if this contributed to the engine failure.

The TSB needs to be replaced according to the Hyundai Dealership. This is a known problem and would normally be covered under warranty but I am just outside of my warranty window and it just started happening. The entire audio system, touch screen controls, and hands-free controls do not work. The touch screen freezes after a few seconds and freezes on my backup camera creating a major driving distraction. The audio system does not shut of once the vehicle has been turned off creating a problem for the battery which I have to manually disconnect or it will continue to power my touchscreen system even after I leave the vehicle. The lane assist, blind spot indicator, and any beeping warning sounds do not work because of the failing TSB. I cannot change my cars settings or hear any warnings from the car's sensors. I believe this is a major manufacturing flaw and Hyundai will not fix it even though those warning sounds are part of the safety features of the vehicle and are a major player in driver safety. The radio controls do not work - volume included. I cannot adjust any noises in the car and beeping warnings are no longer sounding. I am worried that this problem is also affecting any and all car audio warnings such as the forward collision warning, parking collision warning, and lane departure warning.

On May 12 2023 I was driving my vehicle and heard a knocking sound that was unfamiliar. I pulled over and opened my hood and could hear the engine making a continuous knocking noise. I got back into my vehicle to take it to the closest mechanic and the vehicle failed after I had went barely a quarter of a mile. It took Hyundai almost 2.5 weeks to get an appointment with them and another week to have the car diagnosed. The service department called me and said the engine was bad and needed to be replaced. The car engine was still under warranty so my main concern was how long I had been without my vehicle and the rental car costs I was incurring. My vehicle was finally ready and fixed according to the service department. I went picked up my vehicle and started to drive home. As soon as I started to accelerate I noticed the car seemed to be delayed or was having difficulty accelerating. The ac also started hissing and blowing out hot air. I took the car back to the service department and had to wait another week. Finally get a call from Hyundai saying no issues were found and it passed all the tests. I go pick up the car and less then 24 hours later the car acceleration seems to be struggling and the car is having difficulty going past 50 mph. So now I’m back at square one taking my car that Hyundai says is fine back to Hyundai.

I was driving on the highway when my vehicle started decelerating and shutting down completely. I ended up safely pulling over because it could’ve been a serious accident and called FHP they tested my car code p1326 came up I had it towed to the dealership where they assured me I had the extended warranty and that the car should be covered and I don’t have to pay out of pocket. What the dealership told me would take 2 days has now been almost a month and still counting. I’ve had 3 denials for engine replacement due to being outside of warranty with Hyundai even though I have the extended warranty. The dealership has sent pictures and spoke with my case manager at Hyundai to confirm that the engine failure was due to the bent connecting rod bearing that is again covered under warranty. They came back and said other codes populated showing the cause was not the rod bearing but that has to be false. One of the other codes was regarding coolant and I’ve never had any issues with my car overheating or anything prior to my engine shutting down on the highway. I never had any flashing lights or warning signals on my dashboard. This was very unexpected and I refuse to pay for a repair that I didn’t cause especially when this is consistent with Hyundai and their engines. This is a 2019 I should not have any issues. I need a solution quick

The 2019 Hyundai Tucson was being driven home when all of a sudden acceleration was reduced to 25-30 mph. The Engine light went on while this happened. Got the car home, thankfully was off the highway and had it towed to the Dealership. Dealership informed me that it was an engine problem- a cylinder was blown and new engine would be needed on a car that had just reached the 40,000 mile mark. 40 other cars were brought into the dealership the same week and all needed new engines. If this car stopped working on the highway the consequences would have been dire! It is almost 2 weeks without a car- Dealership had no loaners left and we still don't have an answer from Hyundai if they plan to cover the engine still under warranty. We were told Hyundai had been denying allot of engines under warranty. And we were told it takes a long time to get an engine even if approved by Hyundai. If I must rent a car for a month or more, it will be very expensive. If 40 owners showed up at the same dealership in one community in the same week what is happening nationally and why hasn't Hyundai issued a recall? Do we have to wait until people's cars stop operating at full speed on a busy highway causing multi care pile ups before Hyundai speeds up response to repair but more importantly notifies owners of their vehicles this is a problem- a BIG problem!

formance exhaust. I bought catalytic conVerter that they told me to buy for 600+ dollars and took it to child's shop they told me that the catalytic converter isnt clogged nor is it affecting my car and provided me with these codes about the camshaft and crankshaft (P0017,P000B, P000A) which they stated hyundai should have fixed under the engine warranty because it was a recall on these engines on this year car. They stated that even if fixed the converter my car would still perform the same and 3 other mechanics have said the same and stated hyundai would have to fix it. After oil changes the oil consumption in my car is constantly getting oil before its even due for another oil change. I have already paid so much just by having people look at it, buying oil, parts, and etc. i am furious to know that i was sold a car that was recalled with engine problems and been having problems since i got it. I have 2 kids i have to get to and from school and this my only transportation. My car has been misfiring and not going over 40 miles. This is my only vehicle and hyundai has put me in a messed up situation. The recalled was may 2022 and hyundai sold me this car june 9 2022. I contacted the june 15, 2022 about the engine light they kept turning off. Car is stalling, making noise, not holding oil. Have to top oil weeks after getting oil changed

My 2019 HyandI Tucson’s engine light came on, so I checked my engine oil and found it to be 2 quarts low on oil, so I added the missing oil and come to find out that 2 weeks ago I had added one quart of oil. That mean in 3 weeks I added 3 quarts of motor oil. I brought the car to our HuandI dealership where we have our vehicles serviced and explained to them to check for engine oil leaks and when I came back to pick up the car, they told me there was no sign of any oil leaks. So if there are no leaks, where is all this oil going? The engine runs just fine but it’s burning much to much oil. I mean you shouldn’t have to put one quart of oil every week, that’s just crazy.. I will have to bring the car back to the dealership in Centereach NY., and tell them to check again, this car is driven locally by my wife and she never drives over 55 MPH, even on the expressway. This car was never abused. I have a 2004 Chevy Venture with 195 thousand and I never put oil in it, I just have it replaced every 3 thousand miles, that’s it, I did notice that we aren’t the only ones that have this problem with this model car, that’s insane. I may just have to write a letter to the CEO, if they can’t find the problem. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The components that failed are the engine and transmission and parts associated with the functionality of these parts. It is currently in the shop but will be available for inspection upon request once repairs are complete. My safety and others were put at risk when these malfunctions occurred (driving incredibly slow on the highway could cause an accident, accelerator malfunctioning that might break, broken down late at night hours from home, parts catching fire from leaking oil, etc.). The problems have been acknowledged by my warranty company and the two repair shops that have serviced it. My car was inspected by Geico Insurance Company after I got rear-ended and needed to file a claim, however, the inspection was not specifically on my engine/transmission. The warning dash lights didn’t seem to come on until it was too late, especially during the transmission issue. I was driving around for days leading up to this issue thinking it was acting weird because it was due for an oil change but when I got one and nothing improved, I knew something was wrong. The check engine light did not come on until the car started to actively shut down and not move when I pressed the gas. The full detailed complaint is attached and receipts for repairs are available upon request. Attached is an overview of parts and pricing from the warranty company for the two claims.

None of the air bags deployed. The vehicle is currently sitting in a tow yard, but is awaiting a an assessment by the insurance adjuster. If the car is totaled, I do not know where it will go. My safety was compromised both when I was T boned by the first car on the passenger side of my car, which no air bags deployed at that time, and then from that car, I was pushed into oncoming traffic, where I was hit head on from another car. I was jilted to the left and sustained injuries, and then when I was struck head on, I was jilted forward towards the steering wheel, and then jilted backwards, also resulting in injury. I believe all other airbags on the other 2 cars were deployed. However, my car, and myself received the most severe damage to my car and myself. The car has been inspected by the police, and the Tow Truck owner in person. The insurance company, and hospital personnel has viewed the vehicle by pictures only. However, I am awaiting communications from the claims adjuster. I am unaware of any waring lamps etc. as the wreck happened less than a second. I was doing 35-40 mph, and she pulled out in front of me, and I had no chance or opportunity to apply my brakes. I have a chest wall, and left shoulder contusion, a concussion, an a hairline fractured collarbone. I do believe that if the airbags had deployed, I would not have suffered these injuries, or the severity.

I believe that this car is a lemon. Ever since we bought it we have problems with the engine not performing right. I have got the engine system cleaned multiple times one at the dealership and one at Valvoline Oil Change facility. The engine still didn't run smooth. I would always get the oil changed on time and the vehicle has never been in a accident. Now just yesterday the vehicle while driving on the highway just stalled and wouldn't accelerate past 60mph. Now the check engine light is blinking and all of the lights on the dash are on. Also lately sometimes the forward collision lights will come on and other warning lights and sometimes they wont. Another light that intermittently comes on are the auto hold and epb light and this has been happening since we bought the vehicle. I have taken into Hyundai and they basically were like yea sometimes that happens. I have not gotten the new check engine light checked but I am sure that it is something serious because the car won't accelerate past 60mph. I have read on other discussions that there are many problems with Hyundai engines and believe that I am victim to very poor quality manufacturing in this engine. I also have a 2013 Toyota Camry with 180,000 miles and haven't had one problem with it. This car is a lemon and would like to have some help with this please. I have also made a complaint with Hyundai under their drive train warranty.

While driving to work on Thursday, February 23 2023, the car suddenly turned off flashing the check engine light and oil light. I was driving on the palisades interstate parkway in New York and had enough momentum with the car to get off on the next exit. Once the car was safely off of the road, I opened the hood and pulled the dipstick because the oil light was flashing and it was smoking. The oil light never came on before with the car. The car also had the recall for the knock sensor replacement to avoid this engine failure. I called Hyundai and the salesperson directed me to have the car towed to the dealership at my expense. Once at the dealer ship, the service advisor explained that they have had several cars come in with the same issue and that they would get back to me. A couple days later, they explained that the engine had burned all the oil and that Hyundai would replace it. The issue here is that that was my only car. I have a job and a son while other duties to fulfill. I was explained that it would take a while to get a motor since they’ve had cars sitting with the same issue since December and that they also had a wait of double digits people for the next loaner. I did not get an eta of when I would have my car back or when I can get a loaner. They also will not cover rental fees for a rental car. I have been paying for cabs and other forms of transport and still have no estimation of when I will get my car back.

On [XXX] as I was driving down the highway, the check engine light came on the dashboard and the car lost acceleration. I could not go any faster than approximately 30 miles per hour. Very dangerous situation when you’re traveling in a lane of traffic that’s is doing 65/70 mph. I was able to get the car to Premier Hyundai, a dealer in Seaside, CA. At that time there was a recall for the Knock sensor. They replaced the knock sensor at that time and did some other services including an oil change and sent me on my way. They told me at the time that the code that had come up was P1326. Entering this incident now, because I realized I had missed reporting this specific incident. This VIN# has had the issues 5 times since the [XXX] incident and I feel very strongly that this is a HUGE SAFETY ISSUE. when this happens when you are driving down the freeway at 65-70 MPH and it suddenly goes into LIMP MODE. You are at the mercy of the cars that are approaching you from behind doing 70 when you're only able to do 30 mph. This is an ACCIDENT WAITING TO HAPPEN. PLEASE Do SOMETHING. I see where you closed an investigation into these issues. - PLEASE REOPEN the investigation and hold the manufacturer accountable. These settlements they come up with are not worth the paper they're written on. The consumer is getting fed up and we need someone to help us.

The contact owns a 2019 Hyundai Tucson. The contact stated that while driving at 5 MPH, the vehicle slowed down. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the knock sensor needed to be replaced. The vehicle was repaired, but the failure recurred. While driving, a month later, the vehicle slowed down. The vehicle was taken back to the local dealer, where it was diagnosed that the knock sensor needed to be replaced. The vehicle was repaired, but the failure persisted. The vehicle was taken back to the local dealer, where it was diagnosed that the engine needed to be replaced. The engine was replaced. Additionally, while driving, an unknown vehicle crashed into the rear of the vehicle, and it continued to move forward. The steering wheel became stuck and was uncontrollable. The driver shifted the gears to park and neutral. The vehicle was idling high and low. The driver depressed the push-to-start button, but the vehicle continued to move and drove onto the lawn over a flower bed and fence, went across a two-way highway, slowed down, and stopped. The vehicle was towed to a body shop. A police report was filed. There were no reported injuries, fire, or air bag deployment. The manufacturer was contacted to obtain the EDR box, and they sent an engineer who reported that the air bags were not supposed to deploy and was unable to duplicate the failure. The failure mileage was approximately 1,000.

The contact owns a 2019 Hyundai Tucson. The contact stated while driving approximately 45 MPH and merging onto the highway, the vehicle began to lose motive power. The contact stated that the check engine warning light started flashing. The contact stated that a loud humming noise was coming from the engine compartment. Additionally, the steering wheel began to vibrate. The contact pulled off the highway, and at the bottom of the off ramp she had to stop for a traffic light. The contact stated that when the light changed, and she depressed the accelerator pedal, the vehicle lunged forward while shifting from 1st gear into 2nd gear and then stalled. The contact stated that it took several attempts to restart the vehicle. The contact drove to her residence while the vehicle struggled but was unable to exceed 25 MPH. The contact drove the vehicle to an auto parts store and had a diagnostic test performed. The contact was advised that she had a code P1326 and other failures of the powertrain system. The contact called a dealer and was informed that the vehicle would not be diagnosed or repaired the vehicle was diagnosed by their mechanic. The vehicle was diagnosed a second time and the mechanic retrieved DTC: P1326. The vehicle had not been repaired. The contact researched online and related the failure to NHTSA Campaign Number: 21V727000 (Engine) however, the VIN was not included. The manufacturer had not been informed of the failure. The failure mileage was 81,859.

*Inside of car smelt like urine upon start. Car went into limp mode. First trip to dealership, catalytic converter was replaced. After the 6th time to dealership for same issue, manufacture approved engine replacement. *The car went into limp mode which posed a safety risk to our family as well as other vehicles on the road. This happened twice while on the freeway and we could have been rear-ended due to unexpected reduced speed. This also happened twice while turning with oncoming traffic approaching. *The problem was reproduced as this happened 6 times before the manufacture would approve an engine replacement. *The dealership replaced all the fuel injectors. No change engine went into limp mode P1326 (failure code). *The dealership installed a new short block engine. *The engine smelling like urine appears to be the first symptom (catalytic converter failure and replaced). When the car went into limp mode the engine light flashes. P1326 (failure code). Urine smell occurred beginning in July 2022 at (23,926 miles). Car went into limp mode for the first time on September 23 (approximately 25,400). * Another issue we are now addressing not related to the above engine issues: Car fish-tales when you drive over any bump in the road. *The dealership is replacing both rear shock absorbers. They said both shocks were leaking fluid. *Car is very unstable and throws you around (like hydro-planning the pavement is dry). *No warning signs, just started happening.

On three occasions while the vehicle was idling, the dashboard screens and interior lights went completely black, and the steering wheel jerked abruptly in my hands. This sudden electrical failure creates a serious safety concern, particularly if it were to occur while driving at higher speeds. The dealer has not been able to reproduce the problem. There were no warning lamps, messages or other symptoms prior to the failure. There were no warning lamps after the problem occurred. The vehicle has been inspected multiple times by a Hyundai dealership. On one occasion, the dealership retained the vehicle for approximately two months but reported no definitive findings despite error codes being present. On a later visit following another failure, no error codes were recorded. The dealership replaced the head/stereo unit and confirmed no active recalls, yet the issue continues. This problem first occurred while the vehicle was covered under an extended warranty, but due to its intermittent nature, it was not resolved before the warranty mileage threshold was exceeded. I have since found numerous similar complaints online from owners of the same model year describing electrical blackouts and steering-related concerns. A Hyundai service manager advised me to dispose of the vehicle, which further reinforces my concern that the defect may be known but unresolved. I believe this issue represents a potential safety defect and warrants documentation and review. Thank you for your attention to this matter.

I have a Hyundai Tuscon 2019, which was pre-certified by Hyundai. This particular car was part of a lawsuit because of a knock sensor issue. The lawsuit information is here: [XXX] The knock sensor failing is not really what causes the safety issue. The engine symptoms when the sensor fails is the issue. The engine goes into "safety mode" which limits the car to a significant slower speed. The problem is that Hyundai has now tried to fix this issue twice on my vehicle, and the knock sensor continues to fail. To be clear, they've replaced the sensor twice. Based on the lawsuit, the court mandated them to fix the knock sensor. They have done that free of charge, but the sensor continues to fail. To me this sounds like a manufacture issue. It is incredibly dangerous when you're on a highway and the sensor fails. It happened to me, and it was almost catastrophic. The car slowed down and there is nothing you can do about it. I noticed there was something wrong very quickly and put my hazards on. If I didn't, I may not be writing you here. You could easily get into a significant accident, and from that could lead to injury or loss of life. I am asking for a review of this. I have my service records as well as recorded conversations with Hyundai corporate regarding this issue. Service records are attached. I live very close to NHTSA HQ and willing to come in if necessary. To me, this is concerning enough for that..

I am submitting this complaint regarding excessive and abnormal oil consumption in my 2019 Hyundai Tucson. Despite regular maintenance and oil changes performed according to manufacturer recommendations, my vehicle consumes oil at an excessive rate, requiring frequent oil top-offs between oil change intervals. I have experienced low oil levels with little to no warning, which poses a serious safety concern due to the risk of engine failure while driving. The vehicle does not show visible oil leaks, suggesting internal oil consumption. This issue appears to be consistent with numerous consumer complaints involving Hyundai vehicles of similar model years and engines. The dealerships have been unhelpful and dismissive, often stating that the oil consumption is “within normal limits” or requiring lengthy oil consumption tests without offering a permanent solution. I feel I am being given the runaround rather than receiving a meaningful repair or accountability for what appears to be a known defect. Excessive oil consumption can lead to engine damage, stalling, or sudden engine failure, which is a significant safety hazard for myself, passengers, and other drivers. Hyundai dealerships have failed to adequately address or correct the issue, despite the widespread nature of similar complaints and known engine issues associated with Hyundai vehicles. I am requesting that NHTSA investigate this matter further, as this defect affects vehicle safety and reliability and appears to be part of a broader pattern with Hyundai engines.

On [XXX] I dropped off the car to dealership because engine light was on. They said it was the Catalytic converter and replaced it with about 95,607 miles on it. On [XXX] I was driving on a 50mph road and my speed dropped to about 10mph and then the car began shaking and engine light came on. I got it back up 20 mph to get it pulled over to safety Avoiding an accident. I had it towed back to same dealership and told it was the Knock Sensor and had it replaced. On [XXX] engine light began flashing again and I had it towed back to dealership. Argued back and forth with dealership and corporate on safety and honesty. I picked it up on [XXX] and pulled out of dealership and it began jerking and shaking and lost power on a 45 Mph road stopping traffic and avoiding several accidents!. Had it towed to a different dealership that day and it sat there for months. then finally an oil consumption test was begun but engine light returned and then on [XXX] we were driving on a 50 mph road and the speed dropped to about 10 and began shaking violently and then the engine light came on. This time with my 9 year old grandson in the car!!!! And avoiding an accident. Now with about 113,000 Again we had it towed and then the combustion cleaning was done at dealership. Brought it home still in the oil consumption test and now light back on and dealership is saying not burning oil but now Catalytic converter again??? It is Not SAFE to drive . Someone could be KILLED! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have been experiencing serious safety issues with the 2019 Hyundai Tucson I purchased that have been ongoing since February of 2023. The check engine light comes on, begins to flash, and the car goes into 'limp mode' and will not allow me to accelerate faster than 45/50 mph. Consequently, it will further stall on hills due to the inability to accelerate. Below is a brief timeline of this incident: - February 21: Bring in vehicle to dealer as recommended for oil change, tire rotation, cabin air filter, and a recall. The recall issue was as follows: 966 engine monitoring logic, 22-01-028H-1, caused by ecm update, 966 campaign, ecm update op code 10d021r9.3 - February: 24: Check engine light comes on, flashing, and unable to accelerate past 45-50 mph. - February 27: Return to dealer and bring in vehicle for check engine/no acceleration issue. - March 2: Pick up vehicle from dealer - March 8: Check engine light comes on again, flashing, and unable to accelerate past 45-50 mph. - March 9: Return to dealer and bring in vehicle for check engine/no acceleration issue. - April 5: Pick up vehicle from dealer - April 8: Check engine light comes on again, flashing, and unable to accelerate past 45-50 mph. - April 10: Return to dealer and bring in vehicle for check engine/no acceleration issue - April 25: Pick up vehicle from dealer - May 3: Check engine light comes on again, flashing, and unable to accelerate past 45-50 mph. - May 4: Return to dealer and bring in vehicle for check engine/no acceleration issue; car is still at dealer as of May 25

On 11/10/20, I received notification that my 2019 Hyundai tuscon was part of a recall regarding anti-lock brake hyrdaulic electronic control unit could cause an electrical short resulting in an engine compartment fire.i immediately contacted my local dealerships as instructed on the recall letter and was informed that none of the dealerships nationwide actually have the parts in order to fix this recall! I confirmed this by contacting all of the dealerships within a 50MILE radius of me. It is completely irresponsible for Hyundai to issue this recall and yet be unable to fix this problem that is potentially deadly! Also, come to find out, the recall issue date was actually in September 2020 yet I only found out via letter in November!!!! I contacted Hyundai customer service in hopes to get more answers on this and also if I would be able to get a loaner vehicle so that I can get to work while waiting for an unknown amount of time before I am able to get my vehicle repaired. This recall has caused extreme anxiety and fear that my SUV is going to spontaneously catch on fire at any time without warning, even while parked in my driveway!! The dealerships also advised me to park my car far away from my building which only made my worry even worse! I have yet to actually hear back from Hyundai customer service and was given a specific time and day that I would be receiving a call however did not receive a call. Completely disappointed and frustrated that I just purchased this car last year and already want to get rid of it because I do not trust Hyundai one bit now!

On November 13, 2023 I was driving the vehicle and the check engine light came on and it went into "limp mode". I was well aware of what was happening because this is at least the 4th time this has occurred since owning the vehicle. It happened in Dec of 2022, Feb 2023, and again on July 6, 2023, The last time it happened the dealer had it for over a month and could not "reproduce" the problem, so I got the car back without anything really haven been done to fix it. Same as in Dec 2022 and Feb 2023. I had to fight to get the dealership to get me a "loaner" rental and had to pay for it out of my own pocket to start with. Eventually after many, many phone calls, voicemails, emails later - I did get reimbursed. But this did not happen until I email the President of Hyundai and all the executives of Hyundai. I didn't get the car back until a month later and still nothing was done. So here were are 3 months later and it's throwing the same issue/problem and I am back at square one. At this point in time, I am not interested in having it "diagnosed", all I want is for Hyundai to do a "buyback" so that I can get into a vehicle that I can trust to be reliable and not breaking down for no apparent reason every 2-3 months. This is totally ridiculous and the government needs to do more to hold Hyundai accountable for these pieces of crap cars they've put on the market. Irritated is not even the word. Will be calling the Western District Manager today as that is the last person I talked to back in August when I got it back - he said to call him directly and he would "take care of it".

Oil component failure causing extreme heating within the engine and catalytic converter which poses risk for engine fire. This oil consumption issue was addressed by the dealership who ran a test to see how much oil was consumed. The test results showed that the vehicle was burning oil at a high rate and would ultimately result in engine failure. The low-oil light has never come on indicating a need for an oil change. Despite this, I have constantly pulled my own dip stick and got changes every 2,000 miles. For this make and model, they required a change every 5,000 miles. When I notified Hyundai Corporate over this concern. They claimed due to it being outside of warranty, that it does not matter what my engine light has been doing since I got the car, nor the issue with the oil consumption, they refuse to address any of these problems as being a manufacturing problem. The maintenence has been kept up since I got the car, so the manufacturer is not acknowledging the constant issue with Hyundai Tuscon engine dangers. If a fire were to occurr, I was told this is not Hyundai's responsibility due to me not being the first owner and it not falling within warranty. After the combustion test, Hyundai claimed that they refilled my oil. When I checked my dip stick after only driving 100 miles, the image attached will show the resulting levels. My oil light is still not coming on despite this. Even when it has been much lower than the pictured level. This, paired with the super heated catalytic converter due to the oil consumption, is going to cause an engine fire and is not fair to the consumer.

on [XXX], we received the Tucson back from dealer from a complete engine replacement due to recall. On [XXX], our college son was returning to school from visiting a friend. He said he thought the car sounded a little different. There were no engine light warnings, so he didn't think much of it. About an hour into the trip, he started to smell gas, a few minutes later he started to smell smoke and saw smoke coming into the vehicle through the consoles. He looked behind him and saw a trail of fire and smoke. He decided to pull over but the brakes FAILED. He went into the median, applied the emergency brake and waited until the car slowed down. He was able to grab his phone that had fallen beneath his seat from driving onto the median. Once he was out of the vehicle, he could definitely see the car was on fire. It was entirely engulfed in flames within seconds. He called 911 and they were able to put out the fire within 30 minutes, but they commented that it was a difficult fire to extinguish. The car was completely destroyed front to back. We do not know if this problem started with engine, fuel tank or brakes. It is one thing when your car is on fire and you can pull over and get out. It is entirely another when you need to get out of your car but the brakes fail. You have to delay getting out of the car to ensure you don't hurt others on the road and save yourself before it explodes. We are lucky he is alive but are worried for others with this car. We thought we were done with car prolems after the engine replacement but we just moved onto another problem.

I needed to stop quickly, but not unreasonably fast. I had time to consider my passenger and that this would be a quick stop for them. I then firmly applied the brakes and it felt like something kicked in causing the car specifically not to stop or slow down as expected. I subsequently had to push harder and harder to try to get the car to stop, which it didn't in time and I t-boned another vehicle (minor) that then left the scene. My passenger, who I do not have a relationship with and had just met that night, turned to me and said "you're car didn't stop." She noticed this as well. Upon having it fixed at the auto body shop, they found that "the brake pedal is below the gas pedal and keeping brakes applied when brake pedal is released. The brake pedal assembly is bend and holding brake pads applied when driving." I spoke to the technician (owner?) who said that "if the pedal assembly is bending instead of stopping then it is possible that this caused it." He also suggested that "brake assemblies don't bend" and that he has never seen or heard of one bending in his decades of work. All I know is that I applied the brakes quickly, but not unreasonably and the car reacted in a way causing it not to stop when it should have. Whether this was a problem with the ABS or the brake pedal assembly bending, I am not sure. I do want to document that this car did not stop as it should have and feel that a mechanical problem caused this collision. Fortunately we made light contact with the other vehicle, the air bags did not go off and there were no injuries. There was, however serious risk of injury should cars have been only a few feet further in any direction. This car was repaired by a body shop.

While driving at highway speed, the engine suffered a sudden connecting rod bearing failure (Cylinder 3) with no prior warning lamps, messages, or symptoms. The vehicle made a slapping noise, a belt came off, the engine died, and would not restart. The vehicle was towed to an authorized Hyundai dealership. The driver, a [XXX] [XXX] , was able to safely guide the vehicle to a stop without injury. The dealership inspected the engine and confirmed a complete Cylinder 3 connecting rod bearing failure. The technician contacted Hyundai Techline, who confirmed the diagnosis and recommended engine replacement. The estimated repair cost is 6,500. The failed engine is available for inspection at the dealership. This vehicle is a 2019 Tucson with the Nu 2.0L GDI engine, which is covered under the E2 Class Action Settlement for connecting rod bearing defects. Hyundai Service Campaign 966 provides a KSDS software update designed to detect abnormal bearing noise before catastrophic failure occurs. This update was never performed on the vehicle. The 2019 Tucson was not added to Campaign 966 until April 2022, after the vehicle had already been purchased used. The owner was never effectively notified of the campaign and the vehicle was never at a Hyundai dealership where the update could have been performed. Hyundai denied warranty coverage solely because Campaign 966 was not completed, despite confirming the failure is the exact defect type the campaign and settlement were designed to address. The vehicle had only 49,437 miles at the time of failure. The engine failed without any prior warning — the exact scenario Campaign 966 was designed to prevent.

I purchased this vehicle from CarMax about 5 months ago. It had 74,XXX miles. CarMax showed no open recalls and a printed sheet from your site showing the same. Several weeks ago, while driving, the engine seized. I sent it to one of the local Hyundai dealers for repair. Hyundai said because recall Campaign #966 had not been performed, they would not replace the engine under the extended warranty. When I purchased the vehicle, I had the foresight to purchase an extended warranty from Assurant. Eventually I found they will cover the repair. I have to pay the $600 deductible, plus a $350 labor charge for diagnostic work. Here is my problem, CarMax told me there was no open recalls (based on your web site), and I counted on CarMax having an accurate knowledge about this when I purchased the vehicle. This is particularly disturbing because in 2022 CarMax settled out of court with 30+ states in part, for failure to disclose open recalls on vehicles they sold. True, I could have checked myself, but how did your entity report no open recalls on this VIN, and CarMax reported no open recalls on this VIN, but Hyundai was aware of the open recalls, and denied an engine warranty repair because the recall campaign had not been completed? There are two other open campaigns, # 933 and #P33 as well. The Hyundai dealer is going to perform these recalls after the repair. To summarize, I purchased this vehicle in good faith that the information provided on the NHTSA sheet, and the CarMax sheet were correct there were no open recalls. My bank financed the auto under the premise it was a safe reliable risk for them. Now, I'm going to be out $950 plus rental car expenses I've already paid. Please contact me if you have more questions.

I was merging onto a highway at high speeds when the car stuttered. The check engine light began to flash and I lost acceleration. I could push the gas pedal to the floor and the car would not accelerate at all. The car lost it's speed and I could not go anymore than 30mph, and it would not go higher than 2rpms. It put me and my baby (who was in the backseat) in danger as we were going fast on a highway and out of nowhere the car lost speed and I could not accelerate. I could've easily been hit by another driver going the regular speed limit. I drove it to the dealership that just happened to be down the street, and the car struggled to accelerate from a complete stop, as well as in general. From a complete stop, the car would sputter and jerk when pressing on the gas pedal. The dealership diagnosed it as a faulty Knock Sensor. They said they would replace the sensor as it was still under warrenty. When I left the dealership, the check engine light was off and the car was driving fine. Fast forward to the next day, I was driving again on a highway at about 65mph, when the SAME thing happens. The car stuttered, lost all acceleration, and the check engine light was flashing. I ended up driving it home (about 10 miles away) and the whole time I could not go faster than 30mph without the car shaking. This time the car would not go higher than 1.5rpms. I checked the engine at home and a P1326 code came up, which is a code for the Knock Sensor. I called the Hyundai dealership that I originally went to and they said there was nothing they can do about it at the moment since they had just replaced it. Prior to all of this, there was no warning sign at all that this was a potential hazard. It happened so suddenly and both times it happened put me in a dangerous situation.

I had bought my car in May of 2025 and within 12 hours of owning it. The check engine light came on. They replaced the sensor well. A couple days later, the check engine light came on again, and they had to rebuild my whole engine had the car for a month at this time. When they rebuilt the engine, they had the car for over a month. And ever since I got it back, it's always something the same thing has to get repaired. Well, I took it to the shop. Yesterday because it was misfiring, and I needed to have some spark plugs replaced, and they said that the Ignition coil needed to be replaced, but there was a recall on that not too long ago. And they fixed that on the recall. There's no reason that should have already went a few months later. Well, the problem is when I bought my car, I bought it from tar. Hyundai, it's now rusty, while it's Hyundai. They charged me $200 just to get my car out of their lot. Because I refused service because they were trying to charge me. $2500 to fix my car. Now mind you, I've already put over $4000 extra into this car. After purchasing it for over 21000 now they're not wanting to honor any work that Tara. Hyundai done because they don't be responsible. They don't want to honor the tar. Hyundai warranty or anything I've had it with this Hyundai company. I've been driving this lemon. It is yet again in the shop. Being fixed, although the engine was rebuilt a year ago, there is no reason. This car should keep having engine failure. They don't want to honor it. They don't want to give me a new car, they don't want to, they're acting like they don't care like, 00 well, it's your fault, but I did not buy the car, as is it came with a warranty. When they reserved my engine and had to rebuild it. They extended my warranty 2 hundred and fifty thousand miles

The component involved is the engine and associated knock detection system (KSDS). The system triggered a P1326 code indicating abnormal engine knock associated with a known defect condition. On February 14, 2023, while driving on the freeway, the vehicle suddenly entered reduced power (“limp mode”) and lost acceleration capability in active traffic. This created a safety risk, as the vehicle was unable to maintain speed with surrounding traffic or accelerate as needed for normal driving conditions. There were no sufficient warnings prior to the event to allow safe planning or avoidance of the loss of power condition. The system activation itself (P1326 and limp mode) was the first indication of the severity of the issue. The problem has been reproduced multiple times, with repeated P1326 events occurring after the initial incident. The condition has been inspected and partially confirmed by a Hyundai dealership. In March 2026, dealership records documented that oil contamination was causing catalytic converter failure, indicating ongoing engine-related deterioration consistent with the defect condition identified by the knock detection system. Despite these findings, the underlying engine condition has not been resolved. The KSDS system is designed to detect a potentially serious engine defect and limit engine power to prevent further damage. However, it does not correct the underlying defect. As a result, the vehicle may continue to operate with a known compromised condition that can trigger reduced power unexpectedly. This creates an ongoing safety concern. A vehicle that can suddenly lose acceleration due to a known defect presents a risk to the driver, passengers, and other motorists, particularly during freeway driving, merging, or other situations requiring normal engine performance. The vehicle remains available for inspection upon request.

On a road trip while highway driving my 2019 cpo Hyundai TUCSON/10800 miles, the car did this big jolt and the forward vehicle collision detection avoidance, hazard indicator & service now lights went off. The engine rpm's revved up very high continuously. When I came to a stop the car would barely go with the pedal almost floored. This made the driving thru the intersections with cars honking dangerous. When I turned the car off, it reset itself and was back to normal. The very next day on the highway, the car did the exact same thing with even a bigger jolt and all the indicators above went on again for 10 seconds. Pulled over, turned the engine off and the car reset itself. I got to my destination I took it to keyes Hyundai in van nuys, ca. They decided that the transmission computer needed replacing and did it. After picking it up, the very next day the big jolt happened again also while driving on the freeway. This time the side mirror avoidance system, hazard lights and service now indicator lights went off for 10 seconds. I returned it to that same dealer and they had the car for a week and said that they could not find the problem even after talking to the tech line and engineers at Hyundai USA. I said it sounds like the main computer May be the issue but they refused to consider that saying they couldn't find the error codes. They then told me that the error codes recycle itself when turning the the car on and off and get erased!! I have to return home from my road trip and I am very scared to take it back on the road and drive another 1200 miles. It definitely feels dangerous with the car revving at such high rpm's and it barely moving when I bring it to a stop. This occured 3 times now and I am afraid of it happening again and having bought a lemon, potentially. It was purchased @ webb Hyundai in merrillville, in in March of 2020 with 3939 miles on it.

The vehicle is experiencing excessive oil consumption and increasingly severe engine performance symptoms. The oil level drops rapidly between changes, but the loss is not due to external leaks. The engine burns oil internally, causing residue buildup and damage to other components — specifically the intake manifold and catalytic converter, which the dealer has now recommended replacing. These issues align with the symptoms addressed in Hyundai Campaign 966 (Engine Monitoring / Knock Sensor Detection System), which is intended to detect early bearing wear and related oil consumption defects. However, the dealership refused to perform the required campaign diagnostics (bearing inspection, KSDS verification, and oil-consumption test) without charging a diagnostic fee. Even though the engine has not yet fully failed or entered limp mode, the excessive oil consumption is already causing secondary damage to emissions and intake components. If left unresolved, this can escalate to engine seizure, catalytic converter overheating, or exhaust-related fires due to unburned oil entering the converter. These are clear safety hazards that can result in loss of power, smoke, or fire while driving. Multiple Hyundai owners have reported identical problems — excessive oil loss, residue damage to emission systems, and dealer refusals to perform Campaign 966 inspections. These patterns indicate a systemic engine defect that leads to downstream component failures, not isolated wear. Replacing the manifold or converter does not correct the root cause, as oil consumption continues after replacement and will likely damage new parts. The dealer’s refusal to perform the manufacturer’s required diagnostics and their attempt to charge for unrelated repairs prevent proper defect identification. This is a serious and ongoing safety issue affecting Hyundai Tucson and other models with the same engine family.

I took my vehicle to my mechanic for inspection check up. My mechanic told me and supplied paperwork from their scans that the P0420 sensor in the cat converter was shot again (3x in 5 years) and needed to be replaced. The engine light had come on 3 weeks beforehand and I had it read and knew what it was. They sent me to Hyundai dealer as it was under warranty with documentation. I get to Hyundai dealer tell them it needs the sensor for inspection and an investigation for oil leaking from back of the engine. I also told them I was adding 2-3 quarts of oil between oil changes. They told me my mechanic over filled oil by .5 quarts and that's why the engine leaked. They investigated after I disputed by saying an oil change had been performed the day I brought it to them and found a bad head gasket, fuel pump seal, and oil pan seal. They charged my extended warranty for those repairs, shut off engine light for cat converter sensor without replacing it, and made me do an oil consumption test of 1000 miles. Car was still not inspected at this point. After 35 miles check engine light comes back on. Cat converter sensor P0420. I take it back in. They tell me they won't replace it until the oil consumption test is done because they need to know if oil is coming through the exhaust pipes (it was). I complete the test and go in. They tell me engine is burning .5 quarts of oil/1000 miles which is acceptable and as long as I complete oil changes every 5000 miles I will be fine. They then tell me if I want sensor replaced I'm 800 miles over warranty so I have to pay $2400 to replace. Called corporate they're only willing to cover half the repair as "good will" for the cat converter and was quoted $1300 by the dealer in question. Almost a month and still not fixed and still can't get car inspected because the check engine light is tripped by the P0420 sensor in the cat converter. It's the only vehicle my family has. I'm forced to pay to have transportation.

On November 8, 2023 my check engine began flashing and my car lost Speed/Full power. I knew there was a knock sensor issue because I had this replaced in May of 2023 in order to comply with extended warranty services. I immediately pulled over to see if there was an identifiable issue. I was able to make it to a local orileys and they did a diagnostic check. It gave the p1326 code which I researched and found this to be the dreaded "needs a new engine code". I wasn't able to get an appointment until November 21st with a dealership. The one in my area wasn't taking anymore due to have over 100 vehicles with the same issue. My car has been at a dealership now since my November 21 st. It's extremely difficult to get a call from these people with any information. I called Hyundai and got a case manager, but that wasn't much help either. He said the dealership was very difficult for him to get in contact with as well. After numerous attempts and no returned calls or texts, I was finally asked for my maintenance records which I sent. I have all oil change records which showed the maintenance was done and in the correct manner and time frame. On January 10th I was told that my issue was not the rod bearing issue that is covered under warranty, but instead it was a piston slap in my engine and that Hyundai had agreed to pay for half of my engine replacement. My cost would be $3,200 plus they had already charged me $250.00 for a battery replacement. I feel this is Hyundais way of skirting around the warranty wording. The piston slap needs to be covered under their extended warranty. This is all related to their bad engines. There was a specific campaign focused on the p1326 code. I have been without my vehicle for 3 months now and I'm still making payments on an auto loan and paying insurance on a vehicle I can't use. The service manager told me that my car was still drivable, but it's NOT SAFE His exact words. Was notprovided a rental and told it's notcovered

2019 Hyundai Tucson I purchased 13 months ago with a mere 5, 241 miles on it., (Currently 29k mi) from Bert Ogden Subaru/Mazda in Edinburg, TX. On 6/26/22 it Started Shaking violently then "rodknocking" and finally failing in middle of major, high-traffic hwy. Near causing accident. NOwarning lights, check engine lights, oil lights, etc. Car was towed to Tipton Ford Hyundai, in Brownsville, TX. As it urns out (through my own research), my vin# falls under a recall issue that was not fixed prior to purchase nor disclosed to me, re:"engine monitoring and logics warning system failure". More importantly, 2) There are several class-action lawsuits underway, one settled, in which Hyundai was found liable for faulty "class II Theta Engines" and a suit involving "GDI NU 2.OL" (same as my vehicle) leading to rod knocking sensor failure, premature worn bearings and even cars catching fire! This is a no-brainer situation in which hyundai should be replacing my engine as ordered, but instead they are claiming, vehicle "neglect" (all maint. receipts were provided)and rejecting claim(which seems to be their m.o. based on similar complaints / civil filings that are ALL OVER THE WEB) and dealer says Im responsible for paying for new engine. Not sure who is responsible: the dealer I purchased from, for selling me a defective vehicle, the Hyundai dealer it was towed to, or Hyundai itself for denying what is a VERY well known liability on their part and apparently a widespread years-long issues with engine defects, recalls, suits, judgements, etx but have many court transcripts of consumers claiming Hyundai blaming thd customer for "neglect" to avoid replacing engine. I need legal help and advice. I HAVE to have car for work and dealer knows it and seems hyundai does, because they wont cover rental, wont provide "loaner" and seems dealer didnt even debate this with HMA because I purchased vehicle elsewhere. They just accepted Hyundai's denial and is now attempting to take advantage.

While driving a flashing engine light came on in my 2019 Hyundai Tucson. This made the car slow down and have no power. I brought the car to the nearest mechanic, they told me it was the knock sensor and told me it was a recall for this car, I should bring it back to the dealership. I called the dealership and they had told me to bring the car in. They inspected the car on 8/30/24 at 44,990 miles and told me it was the knock sensor and replaced it. On 11/4/24 at 46,246 miles the car was brought back in for the same issue and the car was inspected again, it was the knock sensor. This time the software was replaced. On 1/29/25 at 48,042 while driving on a highway going 70 mph the flashing light comes on again, brought it back to the dealership and I was given a loaner. The reached out to me and told me it was the knock sensor. They had the car for about 5 days. On 2/14/25 at 48,248 again, driving on a highway the flashing engine light appears again. Called the dealership and brought in the car and again, the knock sensor. On 12/31/25 at 56,712, driving on the highway, the flashing light appears again...On 1/2/26 the car goes back to the dealership, they call me and said that it's the strangest thing, the serpentine belt is worn, and it was making a banging sound which was setting off the knock sensor. At this point they offered to put in a new serpentine belt. I refused because after 5 failed attempts, I decided to bring it to my mechanic (I had lost all confidence with Hyundai mechanics). He did replace it. At this point I sent a letter to Hyundai motors stating all the facts that have been happening and asked for a buyout. After their investigation they called me and said, because you brought it to your mechanic they couldn't help me, but, if it happens again, bring it back to Hyundai. On 2/2/26, 57,286, again. I called the dealership and brought it back. This time they said that they didn't have a loaner to give so I rented one, 4 days. This is 5 failed attempts

On [XXX], my wife and I were traveling westbound on [XXX] in the left hand lane approximately 30 miles from Lincoln, NE. I noticed blue smoke coming from my exhaust. I had to maneuver to avoid traffic in the right hand lane to exit. The engine and oil light came on about 30 yards from where we were able to stop safely. There was a large amount of oil on the ground under the vehicle. The vehicle was towed to the nearest dealership in Lincoln, NE. On [XXX], the service manager called and asked who last changed my oil. He explained that the oil plug "was left loose, upon diagnosis for the oil light being on, removing the underbody shield to drain the oil out to inspect it, the plug fell out as it was laying on the shield." Prior to the vehicle becoming disabled there was not any indication of the oil plug being lose such as oil residue on the car or leakage appearing in any driveway. The oil was last changed in early September with over 5000 miles driven. The oil change was completed by Walmart prior to the issuance of the TSB #[XXX] to replace the one time use crush type gasket and to confirm no old washer is stuck in the opening. The dealership has not submitted this for a warranty repair and claims Walmart is the responsible party. The TSB #[XXX] indicates that if engine damage occurs from not following the guidelines is subject to warranty chargeback. However, at the time of the oil change, TSB #[XXX] was not yet issued. It seems odd that there was no oil leakage or oil residue on the car prior to [XXX] that the oil plug would suddenly back out unless the oil plug/pan has some sort of defect. It may be reasonable to believe that Hyundai does not want to upload the warranty on engines that are known to have issues. We have submitted a claim to our insurance company to investigate if this was caused by hitting something on the road and have submitted a claim with Walmart.

On a busy highway, my car broke down. It was due to the rod bearings, specifically, the Hyundai Theta "extended warranty"/recall issue, or "recall" issue. There is currently a class action lawsuit against Hyundai. I had the car towed to Hallmark Hyundai in Nashville, TN. I, however, live in Louisville, KY and I was making a road trip to Nashville, TN. I was told by the Service Rep in Nashville that they couldn't provide me with a loaner vehicle because I would be driving it, back home, out of state to Louisville, KY. I paid for a rental car out-of-pocket. Hyundai Corporate told me it would take 60 days to get reimbursed. I picked up the car at the beginning of July, 2025, after the engine was replaced by Hallmark Hyundai. I was told by Hallmark Hyundai that a service employee performed a test drive but it was immediately noticeable to me that there were still issues. I noticed the gears shifting abnormally and problems with acceleration once I first started driving it, post repairs, but assumed I would be told to give it time. Today, [XXX], the car began to have difficulty accelerating once again, and the engine light illuminated. I couldn't accelerate beyond 45 mph. I phoned Hyundai Corporate Customer Care, relayed the issues, and said I needed a rental car the following morning for a job pre-hire meeting and couldn't pay for one since my credit card was already maxed out due to the first out-of-pocket rental. They refused. They told me to work it out with my local Hyundai dealership. The problem with all of this is that the consumer still incurs many hardships even though the car manufacturer is at fault and the dealerships don't always follow the settlement requirements of providing alternate transportation, a loaner or rental. The manufacturer and dealers are not held accountable and settlements that purport consumer recourse are more geared towards the manufacturer staying in business than the consumer being compensated fairly.
