What 364 owners told NHTSA about the 2022 Hyundai Tucson Fuel Cell

I was driving down the highway going about 60-65mph with cruise control and LKA on. I turned my blinker on to switch lanes, checked my blind spot, and moved over to the left. As I was doing so, a semi switched lanes from the left into the right (my new lane) right in front of me. The truck then slowed down a lot, and usually my Forward Collision Warning would say something if my Adaptive Cruise Control isn’t on (or is and I’m just going too fast to slow down) neither of those things happened. No warning. No automatic brakes. No slowing down. I tried to engage the brakes manually but nothing happened. I slammed into a semi at around 60mph because of 3 different system failures. Not only did I hit the semi at 60mph, apparently my brakes didn’t work at all and I spun out until I hit the concrete barrier on the highway. If my brakes had engaged automatically, I could have slowed down enough to avoid the collision altogether. And if they had engaged manually I could have at least minimized the damage to my vehicle (and myself) because I wouldn’t have hit the concrete barrier as well.

During a recent accident, the driver pressed the brakes but they did not respond, almost as if they locked up. Police at the scene noted there were no skid marks on the road, suggesting the brakes never engaged. The vehicle suffered major side impact damage, including broken windows and crushed passenger-side doors, but none of the airbags deployed. This raises serious concerns about a possible brake system failure and airbag non-deployment defect. The vehicle has not yet been repaired and is available for inspection. Police have reviewed the accident, and the insurance company has also seen the vehicle, but no mechanical inspection has been completed by the manufacturer. There were no warning lights or error messages prior to the failure. The safety of the driver and passengers was put at risk because the car could not be stopped and the airbags did not deploy to provide protection.

I have a lot of questions. I bought the best trim car for safety, but as a result, nothing worked. The damage to my family caused by this was a lot of damage mentally and physically, and it took a lot of time for these results to come out. That ended my view of Hyundai/Kia as a Korean American living in the U.S. I will never repurchase a Korean car. I suspect a sudden acceleration. I decided to report to NHTSA/BBB/Hyundai Motor America/FTC.

The following is an account of what happened when the SUV's brakes failed, which caused serious damage to the 2022 Hyundai Tucson (the "SUV") and also damaged two other vehicles. On February 15 in the afternoon, The SUV was traveling approximately 20-30 mph and was rolling up to a red light. There were about 6 car lengths between the SUV and the next vehicle as driver started pressing the brakes. Driver noticed the SUV wasn't slowing down so Driver started pumping the brakes and still nothing. Driver even looked down to make sure he/she was pressing the right pedal and he/she was. The SUV was getting closer and closer to the vehicle in front. Driver kept trying the brakes, pumping, flooring, everything. The SUV would not slow or stop. Driver tried to avoid the car ahead and did all driver could think of to slow and not hit the car ahead but the SUV would not slow down. The collision warning came on as the SUV struck the right of car in front of it. The emergency braking did not come on. Further, the SUV still did not stop until the tire hit the concrete barrier in the road. The airbag did not deploy. In total three vehicles were damaged as the SUV hit one which pushed it into another at the light. Hyundai corporate consumer assistance was contacted and a case opened. The case manager did the initial reach out after the complaint but has failed to return any phone messages or emails about the case for close to a month.They were told where the vehicle was and consent signed so they could inspect and it remains available for them to do so. The dealership was contacted but the person spoken to said its a corporate issue. The SUV is at a body shop and will be sent to Hyundai for mechanical issues and we are hoping they will look at least then for cause. There were no issues before the accident. No previous brake issue. The SUV is badly damaged. It is available to inspect upon request. The accident could have caused driver or others serious harm.

Purchased vehicle new at dealership with less than 20 miles on it. No aftermarket parts, no accidents or issues. Normal daily conditions, and constant logging on fueleconomy.gov. 08/17/2022 at 8:15 am: Driving 45-55 mph on major freeway with a low/moderate traffic. Roughly 5 miles from home, good road conditions and good weather. Suddenly, Automatic Emergency Braking System engaged (and related cluster lights/alarms displayed on dash). There was NOT a vehicle in front of me, and nearest vehicle in front was roughly 150 ft. away. Emergency brakes engaged so forcefully that I was unable to keep my vehicle moving forward, and vehicle came to a complete stop in the left lane of major freeway. My vehicle instantly turned off (or "died") with the radio still playing, but nothing else on. Had to place the vehicle in park, push the start button, and place the vehicle in drive, in order to continue. Obviously very unexpected. Vehicle behind me had to slam on their brakes (tires squealed) and narrowly avoided hitting my vehicle by about 36-48 inches. I'm unsure how they managed to avoid not hitting me. Unfortunately, the vehicle behind that car could NOT avoid the maneuver, and hit the vehicle that was directly behind me. I do not know if the other vehicle had injured individuals, as I was trying to get out of the left lanes of the 5-lane freeway, coming from a complete stop. Essentially, my vehicle caused someone to hit the vehicle that was directly behind me. I placed my hazard lights on, immediately pushed BlueLink button, but after two (2) times of inability to hear their voices because of breakup, I pushed SOS. Ultimately drove directly to Steele South Loop Hyundai and informed them of incident. Per dealership, they were unable to duplicate the problem, and found no error codes. I am not afraid to drive my car, with only 5,500 miles on it. Requested for dealership to report to you, but do not believe they took me seriously, so I am doing this. MAJOR SAFETY HAZARD

Hello, I am writing because I have experienced mechanical issues with my car since I purchased the automobile. Since I bought the car, I began having problems with the electrical components, the automatic emergency brake engaging while driving, and the chassis. The emergency brake has engaged while driving numerous times and has consistently been unpredictable since I've owned the car. In addition, the car's handling and suspension have been problematic since purchasing the vehicle. The car has driven poorly, with many vibrations and feeling extra loose throughout my owning the car. I received a diagnostic code via my Hyundai app indicating issues related to the chassis. I have contacted Hyundai on far too many instances regarding these problems and have not gotten any resolution. I've expressed my concerns about feeling that the car was unsafe for myself and other drivers on the road. However, Hyundai has still been unresponsive, as indicated by numerous open case files where there was no followthrough. Last week, I was in a car accident with a bus. I believe the accident occurred because of the above-stated problem. Specifically, when the emergency brake unexpectantly engages as it did right before the accident. The car is now at the Hyundai dealership. A representative from the dealership contacted me about my concerns as if the car's problems were new and they were not aware of them. These problems have caused me to experience high-stress levels because of the car's unpredictability and my fear of being in an accident. I desire to receive a two-fold resolution by submitting this letter of complaint. I want to get a properly functioning automobile and to prevent anyone else from being in an accident because of the critical mechanical issues present in the 2022 Hyundai Tucson.
