Hyundai Santa FE 2021

Problem first started on 3/31/22, car starting showing engine light as well as forward safety system off. Car would not accelerate and was shaking spuddering when foot was off the brake. Pulled into a safe location and called Towne Hyundai Genesis of Denville (Rt. 10, NJ) to schedule a service appointment and was told that there were NO appointments or availability until May. I expressed my concern that I did not feel safe driving the vehicle and the response was that I could drop off the car for 4-6 weeks and they would look at it when they had a chance. I asked if there was a loaner car available and they said no that 100's of other people have problems. I took my car to a local shop to see if they could diagnose the issue and they ran a diagnostic test and the error P2127 (Throttle/ Pedal Position Sensor/ Switch E Circuit Low). The Hyundai BlueLink shows 2 alerts for Chassis on 3/31/22 as well. After this date I felt unsafe driving my car and have drove the vehicle a handful of times in 2 1/2 months unable to get an appointment. The alert would come on as soon as you turned the vehicle on until 6/4/22 when it occured while driving on a highway and the car stopped accelerating. I took the vehicle to Hyundai and they updated the system and stated that it was fixed. Within 15 minutes of driving it the issue came back, and I called them and they once again stated that I could leave it there for 4-6 weeks without a loaner. This car is extremely unsafe as it will just stop accelerating without any warning.

The transmission in my 2021 Hyundai Santa Fe has failed multiple times. The first failure occurred within the first two years of owning the vehicle. The car began jerking, hesitating, and struggling to accelerate, and the check engine light came on. The dealership confirmed a transmission issue and replaced the transmission under warranty. After that replacement, the same symptoms returned, and the transmission had to be replaced a second time, again under warranty. The most recent transmission replacement was only a few weeks ago, and the same symptoms are already returning — the vehicle hesitates, jerks, and occasionally loses power when trying to accelerate. These problems create serious safety concerns, especially when merging onto highways or crossing intersections. The hesitation and loss of power make it unpredictable and unsafe to drive. I have two young children who ride in car seats, and I no longer feel confident that this vehicle is safe for my family. Hyundai service employees have acknowledged that this is a known, recurring issue with this model’s transmission design. However, no permanent fix or recall has been issued, and I have been told to continue replacing the transmission under warranty until the coverage runs out. This approach does not address the underlying safety defect. The issue has been confirmed by Hyundai dealerships multiple times. The check engine light has come on before each failure. I am reporting this because repeated transmission failures that cause hesitation and power loss are a clear safety risk, and Hyundai has not provided a lasting solution.

The issue first came up in June 2022. When driving the vehicle and coming to a stop the vehicle lost power and would not drive at all. After a few seconds the check engine light came on. After multiple attempts to shift into gear and restart the vehicle the vehicle did have power but for only about 10 miles before doing it again. We ended up having the vehicle towed to the Hyundai dealership. They told us it was a transmission electric oil pump going out (which is now recalled). They replaced the pump but immediately after getting the vehicle and driving down the road less than a couple of miles, the vehicle lost power again and did the exact same thing. The dealership towed the vehicle back and this time said they will need to replace the whole transmission assembly. After waiting over 3 months they finally replaced it. We got the vehicle back and currently is able to drive. However, the transmission shifts hard and there have been times where the transmission lags for a long time before shifting into gear to make the vehicle move. When it does finally go into gear the vehicle will take off real hard and quick. I do not feel safe in this vehicle. Considering how the vehicle lags and takes off real hard at times, I feel this is putting me at risk for a wreck. This is absolutely unacceptable for a vehicle this new and so few miles. Unfortunately, I do not feel Hyundai will back up their poor product and give a fair refund. We have received a recall notice for the oil pump but they have no solution. This recall does not take into account how poorly the transmission now shifts after being replaced.

My 2021 Hyundai Santa Fe (VIN starting with 5NM) began experiencing a significant failure of the air conditioning system during its third year of ownership. The vehicle developed a persistent refrigerant leak that now requires annual recharges to remain functional. Multiple inspections suggest the failure is due to a porous evaporator core, a component defect that is increasingly reported by owners of this model year as they reach the 3-to-5-year mark. Despite being a documented manufacturing issue, there is currently no recall or warranty extension for this expensive and vital system. The failure of the AC system in a high-humidity environment like South Florida creates a severe safety hazard: Loss of Visibility: Without a functional AC compressor to dehumidify the cabin air, the interior of the windshield fogs over rapidly and completely during rain. This occurs even when the defroster is set to maximum, as the system cannot remove moisture from the air without refrigerant. Driver Impairment: In extreme Florida heat, the cabin temperatures reach levels that cause heat-related fatigue and stress, compromising the driver’s ability to remain alert and react safely to road conditions. On several occasions during heavy Florida rainstorms, the windshield fogged so severely that I had zero visibility of the road ahead. Because the AC system had leaked its refrigerant, the defroster was unable to clear the glass. I was forced to pull off the highway in dangerous conditions because I could not see other vehicles or lane markings. This defect prevents the vehicle’s primary visibility safety equipment (the defogger) from performing its required function.

The rearview backup camera system malfunctioned. The camera was replaced under a safety recall on my 2021 Hyundai Santa Fe. Within four days of the recall repair, the camera continued to fail intermittently, displaying a blank/black screen and not providing a rearview image when the vehicle was placed in reverse. The vehicle is available for inspection upon request. I also have video documentation clearly showing the malfunction occurring. The failure of the rearview camera puts me and others at risk because the system is required to provide visibility behind the vehicle when reversing. When the screen goes blank, I cannot see pedestrians, children, vehicles, or objects behind me. This creates a significant risk of a backing collision, especially in parking lots and residential areas. The vehicle was brought back to the dealership four days after the recall repair because the issue continued. The dealer stated they could not duplicate the issue at the time of inspection and are requesting a diagnostic fee to continue evaluation. However, I have video evidence clearly showing the malfunction occurring after the recall repair. The vehicle has been inspected by the dealership that performed the recall repair. It has not been inspected by police or insurance representatives. The manufacturer has not personally inspected it beyond the dealership performing the recall repair. There were no warning lamps. The issue presents intermittently when shifting into reverse, at which time the display screen fails to show the rearview camera image. The issue first appeared prior to the recall repair and continued within four days after the recall component was replaced.

I am writing to formally express my deep concern and dissatisfaction with the ongoing quality and safety issues I have experienced with my 2021 Hyundai Santa Fe, which I purchased new in March 2021. Despite regular maintenance and careful ownership, this vehicle has presented a persistent pattern of failure—most notably involving the electrical systems, onboard cameras, and overall build quality. Specifically, the following issues have occurred: •The rear backup camera has intermittently failed for an extended period, frequently displaying a black screen or static lines, rendering it unusable. •The front camera system has now failed entirely, disabling several advanced safety features. A warning alert is permanently displayed on the dashboard and cannot be dismissed. •I was recently informed that repairing this front camera will cost approximately $2,400, a significant expense for a system that should not fail this early in the vehicle's life cycle. •The overall quality of the interior materials has proven to be poor, with excessive wear and inconsistent performance of various controls and features. •In general, the engine power and performance fall well below expectations, especially given Hyundai's advertised standards. These recurring issues have not only affected our driving experience but have also introduced serious safety concerns, particularly as critical systems such as cameras and driver-assist features are now non-functional. We have never experienced this extent of problems with any vehicle in our ownership history. At this point, we are extremely disappointed and frustrated, and we feel that Hyundai has failed to uphold the level of quality and reliability expected from a modern, family-oriented SUV.

April 2022 My 2020 one, Honda Santa Fe started rolling backwards in rolling to a flagpole as I was walking away from the car. I tried to to catch up with the car. It had my family inside screaming. But I was unable to stop it from slimming into the fireplace. I let Hyundaiusa know. They recommended that I take the car to the dealer. They promised to reimburse me for rental car after the diagnostic came back. they found nothing wrong with the car and never paid for the reimbursement Now September 2023. Same thing just happened again. I was in McDonald's drive through and I drop my debit card so I got out to get my debit card. I got out of the car and had to close the door and as I bend down at sensed the car start starting to pull away. The car once again started running away for me. I was outside the vehicle, but I was able to jump in the car and apply the brake before it slammed into McDonald's. I have made a police report. And I have a witness from McDonald's That saw the incident. I had already reached out to the attorney General's office About the first time the car rolled away from me in April 2022. They claim that my Hyundai found nothing wrong with the diagnostics. There was no argument I can make except for Being called a liar. The mechanic did a little demonstration showing us how the safety mechanism in the Santa Fe makes it impossible for the car to roll out of park if the doors open or. How it's impossible. Even if the door is open, it shifts back to park. If you hit the drive button with the doors open It automatically shifts to park. .. So there's supposed to be "no way. The car can shift out of park into drive or neutral." It rolled away in 2022 April, and it did it again September 2023.

My sante fe has shifted out of park and rolled away from me on 2 occasions. The first time I was about 30 feet away when my son and husband started screaming for me. The car we rolling across the parking lot. I tried to jump in and hit the brake but was unsuccessful and we slammed into a flag pole. The dealer ran a code reader on it and there was no codes so they denied responsibility. Basically called me a liar [XXX] it happened again In McDonald's drive thru The window lady witnessed it. I got out to.get my debit card and as I was leaning down the car rolled out of park snd started coasting away from me. I again, contacted my Hyundai who assigned another case manager. This case manager promised to reimburse me for a rental I paid for the first time the car rolled away from me. The case worker had told me she set up an appointment at another local dealer and they would have a rental waiting on me the next morning I asked her to call amd confirm the appt and rental and to call me back Never heard from her again After numerous calls and emails I recieved an email stating she could no longer assist me since I had obtained legal counsel. Complete lie I never informed them that I had retained counsel. I merely asked if I needed one. . This was their way of brushing me off for the 2nd time Myhyundai has record of me calling trying to gather a resolution at least 30 xs. I have contacted the attorney general's office who reached out to my dealer and my dealer told them they followed protocol and found no issue that would be a warranty issue Of course they aren't wanting to admit that this is issue because this one case could cost millions in recalls. Now there are more and more people that have had the same experience and I fear there will be death before this is addressed. Please help !!

Message: I own a 2021 Hyundai Santa Fe with the Forward Collision-Avoidance Assist feature installed and activated. The Forward Collision-Avoidance Assist did not function properly to stop my car to avoid a low speed impact. I applied the brakes to stop. I could not avoid impacting another vehicle. The damage was minor. Hyundai did inspect my vehicle braking system on June 8 at Hyundai of Cool Springs. I was not provided full report on findings/corrective action. Hyundai America was supposed to provide a follow up report. I was called today and the Hyundai representative had no details on the brake inspection to share with me. I am suspicious. I think Hyundai is hiding a safety issue. I am reporting this event so the NTSB can contact Hyundai to determine if this is a safety defect needing corrective action. The Hyundai Forward Collision-Avoidance Assist is designed to help detect and monitor the vehicle ahead or help detect a pedestrian or cyclist in the roadway and warn the driver that a collision is imminent with a warning message and an audible warning, and if necessary, apply emergency braking. Ref: Hyundai owner's manual, chapter 7, page 7-2 On page 7-6 the system operation is described: System operation Basic function System warning and control The basic function for Forward Collision- Avoidance Assist is to help warn and control the vehicle depending on the collision level: ‘Collision Warning’, ‘Emergency Braking’ and ‘Stopping vehicle and ending brake control’. OTM070143N Collision Warning • To warn the driver of a collision, the ‘Collision Warning’ warning message will appear on the cluster and an audible warning will sound. • If a vehicle is detected in front, the system will operate when your vehicle speed is between approximately 6~112 mph (10~180 km/h). • If a pedestrian or cyclist is detected in front, the system will operate when your vehicle speed is between approximately 6~53 mph (10~85 k

This car since 6/7/22 has been plagued with issues where is starts cutting out and stalling followed by the check engine light coming on flashing. This has happened many times and just happens while driving down the road. It is a very dangerous condition as you can not predict when it's going to stall out. The car has been in the dealership 3X for this problem and spent over 40 days there. Hyundai replaced the fuel injectors claiming that was the problem. It was over 35 days to get the back ordered parts. They were replaced and the car seemed to be running OK. I drove it for about 150 miles and it ran like new. Then on 8/13/22 while driving in traffic on NH Highway US1, it started doing it again. I went into the Hyundai dealership since was right there. I brought the technician out and showing him my running car with the running car with blinking CEL. They pulled into into the shop and ran a scan on it. They said there was no active codes. I asked to leave the car with hem so it could be investigated and there response we "we don;t have a car for you until next Tuesday". I was forced to drive off in a confirmed dangerous car. I pulled out into traffic on US1 and the car immediately lost power and started cutting out and the CEL was back on and blinking. I turned around on the very next street, turned the car off and back on and the CEL cleared. I pulled back onto US 1 and the car immediately lost power and started cutting out and the CEL was back on and blinking again. This very nearly caused a 2nd accident as ad zero power to accelerate. My concern is Hyundai has no idea what the problem is. They know there is a dangerous problem. The service manager drove the car/confirmed himself there is a serious issue. My other concern is the Hyundai dealership knowingly sent me away in a car they had confirmed for themselves was unsafe nearly causing a accident on the highway. I had to speak with the General manager to get a loaner to leave my defective car.

Engine shut off while driving 70mph in the middle of the mountains in PA during a road trip from VA to MI, 2 adults and one child. No Warning No Check Engine lights No alarms, just shut off. I tried to press the ignition start button but it would not function until the engine was in park, gave no warning or alarm when I pressed it, the engine start button wouldn't respond. At Shutoff, going ~70mph, I had: Zero acceleration Zero power No blinkers No Instrument Cluster (LED Cluster screen installed) The only way I could signal to merge onto the shoulder was to turn on the hazard lights and attempt to merge from the fast lane to the shoulder, completely crossing faster traffic with no blinkers to guide my merging and warn other drivers on the highway. Instrument cluster turned white as if it was being reset and music was still playing in the car Bluetooth connected to my phone. Conditions of the vehicle during shutoff: 1. Adaptive Cruise Control was on, set to 3 car lengths of distance. 2. Lane Keep Assist was on 3. Lane Departure Warning was on 4. Bluetooth was connected 5. Navigation was active and guiding Once I was able to merge to the shoulder, I shifted into park and sat there for about a minute while I tried to calm my family down from what had happened so unexpectedly. After a minute or so, I was able to start the vehicle back up and nervously proceeded back on the highway to continue on with the rest of the trip. I immediately contacted Hyundai when I returned to VA and explained the issue, they took the vehicle into the service department of the dealership that I purchased the vehicle from. Hyundai kept my vehicle for 2 days and drove it "120 miles" but were unable to recreate the problem. They stated that all the systems checked out and there was nothing more they could do. I have since created 2 cases with Hyundai Corporate office to rectify this issue to no avail. Without the issue being recreated, there is nothing they will do for my family.

I hadn't been begging Hyundai to help remove a public safety risk for years ! Today, The service lady witnessed my car have a severe safety defect. Although initially offering a rental car, ultimately denied due to my inability to provide insurance until the 1st. My insurance is valid until tomorrow. N they REFUSED to provide the rental without the insurance being dated for 4 days from today. The man in the service office asked if I needed a ride home!? Suggesting i drive the car home. Hyundai has witnessed this cars emergency parking failing, and are aware that this car has rolled out of gear TWO TIMES, W my son in it !!?? Until today, claiming unable to "duplicate" the defect. And unable to "substantiate " my claims due to not being able to duplicate the deflect. They duplicated the defect today. The car no longer has a safety system, that safely parks the car, when the door is open. The safety system fails, at more then half of the attempts,engage and the car will roll in either direction with the car door wide open The service department duplicated the defect today. They claim to have documented the defect . i would like to believe they will finally do what is right.. The realistic fact that they have chosen to disregard the safety of the community, and refuse to offer the rental car, is extremely dangerous to the community and neglectful to the laws of the Safety Act and my Consumer rights. With now, TWO (NOT AT FAULT) Rollaway accidents , insurers are refusing n to provide coverage for the vehicle. Some only offer liabilit, or want 4 xs the quoted rate. Hyundai is aware that this car is defective.. Hyundai has a recent consent order, for over 54 millionth dollars, for untimely recalls and falsafying reports to the NHSTA . They are now, as they then, are in violation of the Safety Act and the NHSTA Consent Order with Kia in the Theta II engines Class Action The purpose of the Safety Act, is to prevent serious injuries, from known defects before
