Hyundai Tucson 2021

I am the original owner of this car and in June 2025 I brought my car to Hyundai from noises and they told me it had no oil despite me being up to date with oil changes on the vehicle. They told me they were going to do an oil consumption test and once they did that the engine was denied. 6 months later 3 days after an oil change and no check engine light on, the engine fails while I’m on the side of the highway. This car is not safe. Check engine light was not on and I am always up to date with my cars maintenance.

Check engine light comes on flashing for a knock sensor. This has happened four times. Since it is flashing, car goes into limp mode and won’t go over 2000 rpm, low speeds and slow/no acceleration. It is dangerous due to happening on highways and going from cruising speeds to a crawl, with minimal ability to accelerate, very quickly. Sensor has been updated once and sensor has been replaced twice. Currently dealing with corporate after the fourth time of this issue happening. I am still fighting this issue and it’s looking like I will need an attorney.

The contact owns a 2021 Hyundai Tucson. The contact stated that her right-hand thumb was jammed between the front driver's side door. The contact had to insert the fob key into the door's keyhole in order to open the door since the unlock button on the key fob and door button could not unlock to open the door. Medical attention was received for injuries sustained with a broken right-hand thumb and a 2-inch laceration. The vehicle was not diagnosed nor repaired. The dealer and manufacturer were not made aware of the failure. The failure mileage was 4,844.

When sitting at a stop and then accelerating to leave the stop position, the car will go and then all of a sudden it will stall out and I'm pressing the gas pedal, pressing the gas pedal quite a few times before the car even decides to move. This happens when I'm changing lanes on the highway... merging onto the highway... when I'm leaving from a stop sign or a stoplight it happens continuously. It is very dangerous and it can cause a very bad accident....this has been an issue since I had bought the car 3 years ago...it seems to be happening more frequent

Tl* the contact owns a 2021 Hyundai Tucson. The contact received notification of NHTSA campaign number: 20V543000 (service brakes, hydraulic) however, the part to do the recall repair was unavailable. The contact called ciocca Hyundai of quakertown (550 s west end blvd, quakertown, pa 18951, (215) 883-9295) where it was confirmed that the part was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Hyundai dealerships won't perform recall on dangerous ABS issue that causes engine compartment fires. They say to park outside and away from structures, but dealerships say they are only allowed to perform 7 recalls a day because they take "4 hours" but the recall paper work says it should take less then 1 hour. So they are booked for months and months leaving us without a way to get the dangerous fire causing issue fixed. This is a serious enough issue, that should be priority even before their sales. It's disgusting what Hyundai has been getting away with concerning their faulty vehicles.

Forward crash avoidance system keeps activating causing the car to brake on it's own. This was previously fixed on my car once back in 2022 and now in 2026 it is happening again. I have been trying to communicate with Hyundai regarding additional years to current recall but their not going to even though they have known for years this was an issue and included older models than their current recall. This is not a one time issue this is the second time and until fixed it continously caused the vechile to randomly brake, it's going to get someone seriously injured or killed if they don't address it.

The failure mileage was 69,493.

I was trying to defrost my windows and my air was on so I clicked the air off so the heat could come on and I started smelling a matalicky smell. I drove to a stop light and when I stopped the back windshield popped and then shattered. I then went to drive again to take the car home and I started to see smoke. Once the light changed I continued to drive to get the car home I happened to look through the rear view mirror and saw fire in the trunk , once I saw the fire I pulled over on a street and stopped the car and then all the sirens in the car started going off so I turned the car off got out and called 911.

Engine started making a knocking sound, then the oil light came on followed by the check engine light. Accelerates and decelerates on its own. Was forced to immediately pull over across three lanes on Interstate 95. It’s been over two weeks and I’ve yet to hear if Hyundai is going to cover a replacement engine. However, what happened is exactly what they have listed on their website ️ What to look out for check-engine Check Engine oil-light Engine Oil Pressure A knocking noise from the engine that increases in frequency as the engine rpm increases. Reduced power and/or hesitation and vibration. Illumination of the “check engine” light in the instrument cluster. Illumination of the “engine oil pressure” warning lamp.

I was merging onto interstate traffic when the vehicle suddenly stuttered and decelerated. I managed to merge, then cross over several lanes of traffic and pulled over. Thought maybe a fuel problem (I had just filled the tank), or overheating. It only has 24K miles on it, and I've faithfully taken the vehicle to the dealer for regular service intervals, so I know it is not a fluid leak or problem. after a few minutes, I was able to start the car again, but it immediately shut down. Did this several times before giving up and calling for a tow truck. Had it towed to the dealer, and the next day they told me it needed a new engine, but the service department needed approval from corporate Hyundai. I'm waiting with baited breath.

The contact owns a 2021 Hyundai Tucson. The contact stated while driving at various speeds, the vehicle intermittently failed to respond while the accelerator pedal was depressed.

Forward Collision Avoidance Assist is on and will not go off. Only has 16,900 miles and is newly out of warranty except for 5yr 50,000 bumper warranty. Dealer at Allen Turner says noat way they will cover this because my Vin is not listed in the latest recall. This vehicle was purchased new and has been maintained as required by manufacture . So, I am [XXX] and have purchased new Hyandais before. I do not at this time in my life have the means to fix this issue. Is there any help on this from Manufacture since this is so newly out of warranty and low mileage. I do not know what to expect as to causing a road accident and hurting myself or someone else. My phone is [XXX] and address is [XXX] Email is [XXX]. Kind regards. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2021 Hyundai Tucson. The contact stated that while driving at various speeds, the check engine warning light was frequently illuminated on the instrument panel. The contact had taken the vehicle to various independent mechanics and was informed that the engine was consuming an excessive amount of engine oil. The contact had taken the vehicle to a dealer for service, and upon inspection, the contact was informed that the engine needed to be replaced. The contact was provided with an estimate for the engine replacement. The manufacturer was notified of the failure but offered no assistance. The contact was initially informed that the vehicle was covered under warranty; however, the contact was later informed that there was no warranty on the vehicle. The vehicle was not yet repaired. The failure mileage was approximately 89,000.

Hyundai Tucson anti-lock brake system modules corrode internally and cause an electrical short and fire. They issued a recall, and their notices say it will take less then one hour to perform installation of new ABS modules, yet all dealerships say it takes half a day. I just visited a dealership who didn't even have the parts to do it!!! And each service department only schedule 5-7 recalls per day. So all dealerships are booked for months and months out. Leaving us all with this very dangerous defect, threatening to burn down our homes. This is not a recall being performed in a timely matter considering how potentially serious it is. They should be banned from selling any more vehicles until this problem is completely fixed. So what are all of us consumers who can't get this recall fixed supposed to do if our vehicles suddenly bursts into flames?

The contact owned a 2021 Hyundai Tucson. The contact stated that immediately after purchasing the certified vehicle, the vehicle went into LIMP Mode while her grandson was driving approximately 65 MPH, and the vehicle decelerated to 7 MPH. The vehicle was towed to the local dealer who diagnosed that the NOX sensor had failed and needed to be replaced. The vehicle was repaired but while leaving the dealer, the failure reoccurred. The vehicle was towed back to the dealer who replaced a second NOX sensor and the catalytic converter. The contact stated that days after retrieving the vehicle, the failure reoccurred, and the vehicle was towed back to the dealer who diagnosed that the NOX sensor had failed for a third time, within several days of owning the vehicle. The vehicle was traded in. The manufacturer was notified of the failure. The failure mileage was 28,944.

In October 2025, while the vehicle was still under Hyundai’s 5-year warranty, an authorized Hyundai dealership diagnosed a significant electrical failure affecting the ABS/ESC system on my 2021 Hyundai Tucson. The vehicle was experiencing multiple dashboard warning lights, intermittent key fob malfunction, alarm system failure, and progressive electrical instability affecting safe operation. Dealer diagnostic trouble codes included C120001, C167581, and C164202, with technician notes stating “ABS sensor wiring harness fault found.” The dealership recommended replacement of the wiring harness, estimated at approximately $12,000, but no warranty repair was performed. Since the initial diagnosis, the condition has continued to worsen with additional warning lights and ongoing ABS/electrical system instability. The issue remains unresolved and continues to affect vehicle safety.

The contact owned a 2021 Hyundai Tucson. The contact stated that while driving at 10 MPH, an abnormal clicking sound was coming from under the hood. No warning lights illuminated. In addition, the contact managed to pull over to the shoulder of the road, where white smoke was noticed leaking from under the hood, and the intensity was increasing while the smoke turned black. The local fire department arrived on scene to extinguish the fire. The source of the fire was not identified. It was unknown if a Fire report was filed. A police report was filed. No injuries were sustained, and medical attention was not sought. The vehicle was towed to the contact's residence. The vehicle was deemed a total loss as it was majoily consumed by the fire. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 65,000.

My 2021 Hyundai Tucson has experienced repeated engine-related failures associated with a knock sensor (P1326) fault that causes the vehicle to enter limp mode and lose power while driving. This issue has occurred multiple times at approximately 15,000, 17,000, 41,000, and 90,000 miles and has resulted in four separate incidents requiring towing. During these events, the vehicle suddenly loses power and cannot maintain normal driving speed, creating a hazardous condition while in traffic. The vehicle has undergone multiple repair attempts, including an ECM update and three knock sensor replacements. Despite these repairs, the issue continues to recur and no root cause has been identified. Hyundai has not provided a permanent fix and has advised continued operation of the vehicle unless the issue occurs again. This ongoing condition presents a safety concern due to the risk of sudden loss of power while driving.

Vehicle stalled approximately 15 times between April 17 and May 4, 2026, including once on Interstate XXX at approximately 50mph with minor children ages [XXX] and [XXX] in the vehicle. The oil and battery lights illuminated simultaneously at each stall. Diagnosed as ABS module failure first, then left front wheel speed sensor failure on the 2nd occasion, both confirmed by a Hyundai dealership. Multiple warning lights illuminated, including check blind spot and anti lock brake system messages on the dashboard BUT no error codes following the 2nd repair. The vehicle has been inspected and repaired twice by the manufacturer’s dealership with a 3rd repair currently pending as of May 11, 2026. An open case has been filed with Hyundai Motor America regarding this issue. Issue remains unresolved and the vehicle is still at the dealership.

The contact owns a 2021 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the accelerator pedal was depressed, but the vehicle failed to accelerate as intended. The check engine warning light was illuminated. The contact stated that the vehicle failed to exceed 20 MPH. The contact stated that the failure had occurred while driving on a busy highway. The contact safely pulled over to the shoulder of the roadway. The vehicle was then towed to the dealer, where it was diagnosed with engine knock sensor failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The manufacturer informed the contact that the repair was not covered under an unknown recall due to a lack of maintenance records. The contact was advised to contact the Better Business Bureau. The failure mileage was approximately 60,000.

While driving on the freeway, my 2021 Hyundai Tucson SE (72,021 miles) suddenly and without warning lost power and entered limp mode. I was able to safely maneuver to the shoulder and exit the freeway. The check engine light came on and is currently flashing. I took the vehicle to AutoZone where code P1326 was retrieved. I then took it to Pep Boys for a full diagnostic where P1326 was the only code present. The Pep Boys report states the vehicle requires immediate attention. The vehicle remains in limp mode and the check engine light is flashing. The vehicle is not being driven as it cannot safely reach freeway speeds. I contacted Hyundai Customer Care and was assigned Case # XXX. I also contacted a Hyundai dealership who attempted to charge a 225 diagnostic fee despite P1326 being a known Hyundai defect covered under recall/service campaign.

Around November 1, 2024 my 2021 Tucson check engine light came on. I had this checked out and was told by a mechanic that it was the Camshaft Sensor. I had this repaired and then on November 23rd while traveling to Ohio my Check Engine light started flashing and needed immediate attention. I was on the West Virginia Turnpike when this happened and it caused the car to go no more that 45 mph in a zone marked 65mph. We got this immediately checked out and repaired and then 4 days later the same thing happened while in Ohio. It was taken to Deihl Hyundai in Massillon, Ohio and they once again made this repair with video evidence of said repairs. Once again while driving at freeway speed on December 23rd my car experienced this malfunction. The same dealership fixed it once again with direction from Hyundai. I am concerned for this is an ongoing problem and could cause serious injury to myself or others in my vehicle if this would happen once again on a freeway.

The contact owns a 2021 Hyundai Tucson. The contact stated that while driving 35-45 MPH, the vehicle shut off unexpectedly. There was an abnormal rattling sound coming from the vehicle. Additionally, the contact stated that the vehicle failed to accelerate while driving. There were no warning lights illuminated. The vehicle was taken to the local dealer where it was diagnosed that the rod bearing and the engine needed to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was taken to another local dealer, Hyundai of Orange Park (7600 Blanding Blvd, Jacksonville, FL 32244); who determined that the coils needed to be replaced. The vehicle was not repaired. The vehicle was taken to an independent mechanic who replaced the coils and determined the failure was due to the engine. The vehicle was repaired, but the failure reoccurred. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 124,500.

The contact owns a 2021 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The check engine warning light was illuminated. The vehicle was driven to the shoulder of the road before being driven to the residence. The contact’s neighbor checked the oil level and informed the contact that the oil pan was empty. The oil level was topped off. The contact stated that the vehicle was not due for an oil change for another 200 miles. The vehicle was towed to the dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact was informed that there was no oil in the oil pan. The contact was informed to provide the vehicle service records. The contact stated that the failure was a manufacturer's failure. The manufacturer was made aware of the failure, and two cases were filed. The failure mileage was approximately 44,807.

The vehicle experienced a catalytic converter efficiency failure that was confirmed by an authorized dealership in January 2025. The dealer indicated the catalytic converter required replacement; however, the replacement was not performed, and the vehicle was returned to service with an unresolved emissions defect. Less than one year later, the vehicle developed recurring emissions system failure, loss of power, drivability issues, and repeated warning indicators. The vehicle is currently out of service while additional components, including oxygen sensors and spark plugs, are reported to be affected. The manufacturer is declining to replace the catalytic converter and is attributing the condition to oil consumption despite the prior unresolved emissions failure. The issue has been confirmed by dealership diagnostics and has resulted in prolonged loss of use of the vehicle. This appears to be a continuing engine and exhaust/emissions system defect that was not properly remedied when first identified and may affect safe operation of the vehicle.

I took my car in to Allen Samuals Hyundai dealership to have the 9C2 recall update completed on May 15th 2026. Ever since then my vehicle has had a rough hesitation or sputtering when driving. On May 18th Hyundai released a statement stating there was an issue with the update completed on the 9C2 campaign. However no resolution at the moment and to allow the car to warm up prior to driving it. I have only had my car for a little over 2 years and maintained everything a responsible car owner should. It only has 90k miles on it and had zero issues at all prior to the 9C2 campaign. I have spoke woth dealer and corporate numerous times nobody can give me a solution nor does it seem that anyone wants to. Since then the campaign has been closed and its almost as if it never existed. I do have an active case open with Hyundai 43228380 however they act as if they dont know anything about it. They are empathetic to the situation but can't really help or give a solution. All I want it my car that had zero issues prior to this update to run properly again. I dont even drive it much anymore for fear that it will mess my engine up.

Received recall notice that the possibility exist that a battery compartment fire could happen. Recall notice also stated that vehicle should 'not be parked indoors.' The recall notice also stated 'an electrical short in the ABS module could increase the risk of an engine compartment fire.' So we don't dare park the car in our garage since it is located beneath our home, thereby leaving a new car out in the elements at all times. In addition as senior citizens our safety and well being are being jeopardized as we cannot enter our vehicle from inside our home, but must enter from the street in all types of inclement weather. We called the service department but did not receive a call back. We reached out to our salesman and he was the one who gave us information on the recall and added our name to the repair list. However when we didn't hear from them with an update we took a drive to the dealer. During the visit to the dealer in March we were told the piece is on back order. Today I called the service department and was told there is no date yet to fix this recall. How long are we expected to wait for the 'fix' and to leave our car outside?

In the initial NHTSA Tucson recall, dated September 4, 2020, the only 2021MY Tucson vehicles to be included were those manufactured through 3/31/20 and specifically on 6/23/20. Once the problem with the ABS module had been identified and confirmed, and the recall issued, Hyundai continued to manufacture, and sell Tucson vehicles with the same known safety flaw. Rather than shut down the production line until corrections could be made, Hyundai continued to 'investigate' the problem while 2021MY Tucson vehicles manufactured after the end of August 2020 continued to be sold. Hyundai continued to sell these cars while at the same time admitting in NHTSA documents that the company was 'unsuccessful in determining the exact root cause' of the problem. Instead, the company 'concluded that the risk of an electrical short resulting in a fire could be mitigated [not eliminated] by limiting the operating current in the ABS module through a lower amperage fuse.' It wasn't until November of 2020 that a production change was implemented. Then, in December of 2020, the September recall was expanded to include vehicles manufactured through November 2020.

I was contacted by Hyundai last year about a possible recall on my engine so I brought it in October 2023 to have it checked out. I was told that everything with the car was fine. Fast forward to last week 02-21-2024 and my engine starts shutting off while driving ON THE HIGHWAY? I have it towed to a new dealership in Jacksonville FL Jenkins Hyundai I believe. They inform me that it is indeed the engine and it will be replaced for free under warranty. However, it’s been over a week and the parts for the car are still not available. I have researched online and found I am far from the only one this has happened to. I was not given a loaner car and they did not offer to pay for my rental but I was told they would reimburse me. I was also told that they would just pay every week for a rental car for me but then I was later told that that was a flat out lie. After March 7th when the rental car I have is to be returned I can no longer afford a rental car and will not have access to reliable transportation. This could potentially result in me losing my job. This is unacceptable and Hyundai should be investigated and held accountable for selling cars they know have faulty engines.

March of 2021 I purchased a new Hyundai Tucson SEL. I have performed all required maintenance (at the dealer no less). In May of 2022 the dealer performed the recall Campaign 966. Since that time, my Tucson has had to go to the dealer 5 times for a P1326 code. This resulted in the check engine light flashing and the car going into protection or limp mode. The vehicle would not accelerate past 30 mph and would not exceed 2000 RPM. This has happened as I have accelerated from either a stop or while in traffic. As of yet the dealer has been unable to permanently resolve the problem. They have replaced the knock sensor. The dealer has replaced spark plugs. The dealer has also replaced the catalytic convertor. They also recently scoped the cylinders and cleaned the engine with pressurized engine detergent. In the days and weeks prior to the check engine light, I can always tell that failure is imminent. The gas mileage will slowly drop off during both highway and city driving. Additionally, I can feel through the gas pedal hesitations and slight rhythmic pulsing. Lastly, I can feel gradual power loss in acceleration and very slight hesitations in acceleration as well.

The contact called on behalf of his girlfriend who owned a 2021 Hyundai Tucson. The contact stated while driving 5 MPH in the driveway, there was steam coming out from under the hood. There was no warning light illuminated. The contact parked the vehicle. The contact stated that as he opened the hood, flames came out. The contact's girlfriend also saw flames coming out of the A/C vents. The contact closed the hood and assisted his girlfriend and his pet in exiting the vehicle. The contact stated that his girlfriend slipped and fell while exiting the vehicle. The contact's girlfriend sustained back pain and the contact sustained a flash burn. There was no further information provided. The contact stated that the entire vehicle caught on fire. The contact was able to extinguish the fire with the assistance of the fire department. A fire department report was filed. No police report was filed. The insurance company technician determined that the fire originated from the engine compartment. The vehicle was totaled by the insurance company and remained in the contats driveway. The dealer was not notified of the failure. The manufacturer was notified of the failure, and a case was opened. The failure mileage was approximately 25,000.

I've had numerous issues with my vehicle, including power steering, brakes, loss of power, and more. On a few occasions, I started my vehicle and put it into drive, only to find that the power steering hadn't disengaged. This led to near collisions, such as almost hitting another vehicle while backing out of a parking spot and nearly running into a wall. I've reported these issues to Hyundai multiple times, but the dealership can't reproduce the problem, despite having recordings of the incidents. I've also experienced delayed release of the electronic e-brake and it feeling like it hadn't fully disengaged. In a recent event, with passengers in the car, the e-brake auto-engaged while driving downhill, bringing the vehicle to a halt. I had to manually disengage it and restart the vehicle to resume normal operation. I contacted Hyundai customer service again, but I'm still waiting for a formal response. Other symptoms include loss of power during acceleration, engine starting issues, stuttering, and occasional burning smell from the brakes. Despite my efforts, Hyundai hasn't provided any solutions to these problems. I drive with multiple passengers in my vehicle all the time, including children and have major concerns regarding any of these issues happening, let alone while I am driving at higher speeds or with someone else driving my vehicle.

What component or system failed or malfunctioned, and is it available for inspection upon request? Steering column. How was your safety or the safety of others put at risk? Steering column would not disengage and remained locked up after the vehicle was started and in gear. This have caused me to almost get into a few collisions for the same issue. I have had friends and family, most recently my daughter, in the vehicle when these issues have occurred. I have almost collided with walls, cars, etc due to this issue. Has the problem been reproduced or confirmed by a dealer or independent service center? No. Despite the numerous videos I have presented documenting these incidents, they state they have been unable to reproduce. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Manufacture has not inspected the vehicle and keeps sending me to the local dealership where the vehicle was purchased from. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. During the issues where the steering column does not unlock or disengage, it displays a yellow light with a car and key symbol in it. During other issues I have experienced with this vehicle (phantom braking, acceleration / power issues, random dash controls turning on, and the electric e-brake failing to properly disengage, there have been no lots on the dash that were noticeable. Restarting the vehicle tends to rectify the issue.

Dear sir: "Hyundai recently told owners of newer Tucson vehicles not to drive their recalled SUVS if the antilock brake system (ABS) warning light comes on, and to keep the vehicles parked outdoors so they don't catch a house or garage on fire."this particular Hyundai dealership in question here has never mentioned it to me even though the sales agent ([xxx]) was asked by my friend that was with me to assist me with/help me out in dealing with the negotiation that is, always, a common practice when one wants to buy both used or new car. I was then, unexpectedly, advised by the next day, by my friend, about this unfortunate and extremely bad news; of course, after a thorough research, to find out whether my new car (2021 Hyundai Tucson SUV was recalled by the authorities or not. From what he told me, he, simply, plugged in the VIN number ([xxx]) and did the searching. The result was very serious and life-threatening for both myself and my daughter.i will be looking forward to hearing from you soon on this matter of great importance to me as well as my daughter and family members. In addition, I want you to, please, communicate with me through email or regular mail. I have the intent to seek for an attorney to, directly, take over my case and deal with the dealership in question here. I, further notify you that my friend is not going to bring you the $5,000 that he promised to you. That ($5,000) will be used towards the attorney fee. Ps this car in question was bought on 01/09/2021 sincerely yours, [xxx] information redacted pursuant to the freedom of information act (FOIA), 5 u.s.c. 552(B)(6). *Tr

On [XXX], the vehicle was involved in a complex multi-impact accident. It was struck by a vehicle on the passenger (right) side and, simultaneously, by another vehicle on the driver's (left) side. (Police Report). During this sequence of collisions, and despite the magnitude of the impact, I must express my extreme concern that the left side airbag (driver's side) did not deploy. This failure caused Mr. [XXX] , the undersigned, to suffer a neck injury as a direct consequence of the incident. Even more seriously, the right-side passenger, Ms. [XXX] , sufferedsevere internal injuries, including three small intestine perforations, according to medical reports. These injuries resulted from improper pressure or malfunction of the seatbelt for that seat. These combined failures, the non-deployment of an essential airbag in impact, and the serious internal injuries caused by the seatbelt represent unacceptable deficiencies in the vehicle's safety systems. We believe that these injuries could have been avoided or mitigated if the safety components had functioned properly, as expected in an accident situation of this magnitude. Therefore, I am at a loss to understand: 1. Why the left side airbag did not deploy during the impact. 2. Why the right passenger seatbelt caused such serious internal injuries, including the three diagnosed intestinal perforations. We also require that concrete and immediate action be taken to address and compensate for the serious injuries suffered by the vehicle's occupants, as this has caused psychological and work- related harm.

I was driving down [XXX] from my house.My engine light started to flash.I tried to accelerate my car barely went 10 miles an hour.I got Home 2 minutes later.There was major knocking.I had the car towed to [XXX], Hyundai, the only code that is showing up on the diagnostics, is P1326 there is an open class action lawsuit for this exact code. For the rod bearing failure, Hyundai is denying the claim, saying there's a gap in maintenance history on a car. I didn't own yet when I bought the vehicle. It passed a 190 point inspection. There's no way there was anything wrong with this vehicle.I am under fifty thousand miles , and if I was on the highway , it could've been deadly i could not accelerate. No other lights were on in the vehicle, except for the flashing engine light.I have already reported to the better business bureau and they have sent it to arbitration. I have contacted the escalation department for Hyundai.They opened up to separate cases.The agent that was assigned to me didn't even get the code from [XXX], they just denied the claim without it.I have the emails to prove that I had to give it to her. I have.\n All my maintenance history, but as you can see from the text message from XXX Hyundai, they are requesting maintenance for a car that wasn't in my possession yet. They're asking for dates from a year before I had the car, I bought it through EchoPark. I have everyone on my side including fFdelity , as I tried to go through Fidelity and they said they couldn't approve the warranty because of the class action lawsuit against Hyundai for that exact manufacturer malfunction. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

What component or system failed or malfunctioned, and is it available for inspection upon request? Vehicle was running exceptionally well until a software update was applied at the dealership. Hyundai has no recalls / safety campaigns on file for my vehicle make and model and was adamant that no updates should have been applied. On or shortly after this time, vehicle performance became really poor. mpg per tank dropped to around 22 / 23 mpg highway (normally 27-29 mpg), acceleration performance was reduced, and it felt as thought vehicle had issues accelerating at time. Shifting on hills became an issue as well as the vehicle did not appear to properly shift into the next gear when necessary. I was notified after purchase of the vehicle that it should be parked outside of my garage due to possible fire concerns even though my vehicle was supposedly not affected. How was your safety or the safety of others put at risk? Lack of power / acceleration when needed affected getting onto the highway and shifting lanes. Vehicle rode almost like brake was being continuously applied and slowing down the vehicle at times. Lack of power and improper shifting almost caused an accident or two. Has the problem been reproduced or confirmed by a dealer or independent service center? No, dealer was unable to reproduce after a quick 10 minute test drive on flat land. I started keeping records and screenshots afterwards. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Hyundai refuses to contact me back regarding these issues. During this time, an email was sent globally indicating that Hyundai BlueLink would no longer support a feature that independently slowed / stopped vehicles in case of theft. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning lights have appeared on this vehicle.

Purchase new Tucson from Hyundai of Saint Augustine FL in April 2021, the vehicle worked fine. Then in July 2021 the vacuum assist brakes would not hold a vacuum after the engine was shut down, so when you went to start the vehicle it required excessive pressure on the brake peddle to clear the interlock before the vehicle would start. Took vehicle to dealer and told service writer that I thought it was the Check Valve leaking. After 2 hours service writer told me Tucson was ready and their technician did not find anything wrong and that there is no Check Valve. Drove vehicle home and the vacuum assist brake was still not correct so I filed a case with Hyundai USA (#18769467) about the problem and waited for them to contact me. When they contacted me they told me to take it back to dealer and they would fix the problem. I know enough about vehicles that use engine vacuum for power assist brakes have a check valve, so before I went back to dealer I looked up the part number (59139-2W000) vacuum intensifier, and the Hyundai patent (US7752841B2) which clearly shows a check valve. Went back to dealer in October as instructed by Hyundai and told the service writer the same thing I told him the first time. Waited 2 hours again and was told the technician did not find anything wrong and there is no check valve. I then showed him the part number and said that is the check valve. He said he would check with the service manager to see if Hyundai would cover the cost to replace the part and would call me later. Got the call and was informed that Hyundai would NOT pay to replace the part because the dealership technician did not find any thing wrong. How could the technician find anything wrong with a check valve when he said there is no check valve in the brake system. If the engine quit while I was driving I would not have power assist brakes which could cause an accident. I bought the part from different dealer & installed it, brakes work fine now.

My family’s safety is at serious risk with my 2021 Hyundai Tucson, which I’ve owned only 55 days. This vehicle has stalled three times while driving, putting me and my two young children in immediate danger. Each time, the car operated normally until a flashing engine light appeared, RPMs spiked, and the vehicle suddenly lost all power—entering “limp mode” and unable to exceed 3,000 RPM or 50 MPH. The first failure occurred 9/14/25 while merging onto the interstate, forcing me to lose power mid-acceleration as surrounding vehicles slammed their brakes to avoid collision. 13 days later, it happened again in stop-and-go traffic, leaving me stranded on the shoulder. Both incidents occurred without warning or prior check-engine lights. The third—and most terrifying—incident was on October 17, 2025, when the engine completely died 300 miles from home on a busy highway. My children, ages 4 and 6, were terrified as cars sped by. We were extremely fortunate not to have been hit. I am urgently requesting assistance for the immediate replacement of this vehicle’s engine. It is covered by Hyundai’s 15-year/150,000-mile extended warranty, clear evidence the company was aware of these issues. Service records from the previous owner-that I was told about by Hyundai show ongoing engine problems and recalls since 2022 further proof this vehicle should have been retired from service As a parent, I’m very alarmed that Hyundai refuses to act until “catastrophic damage” occurs. This policy is irresponsible and endangers entire families. There’s at least 50 NHTSA complaints describing identical issues; stalling, power loss, and bearing failure linked to defective connecting rod bearings. Yet, Hyundai has denied a replacement, insisting on waiting for further damage and failures in operation. I beg you to intervene and prioritize my family’s safety before tragedy inevitably strikes. My children should not be put at risk due to corporate negligence, greed and absence of accountability.
