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

On 3 occasions over my 18-month ownership of this certified pre-owned Hyundai 2022 Tucson, the vehicle surged suddenly forward WITH BRAKE APPLIED at creeping (parking) speeds of 3-4 mph. No warning lamps were observed. On the most recent (3rd) occasion, a crash over a sidewalk and into a storefront caused $10,000 damage. No pedestrians were harmed, no airbags deployed and neither passenger was harmed. The service department is "unable to duplicate" the surging behavior and declares the car mechanically "safe to drive."

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.

It was around 7 in the morning and I was getting ready for work. My garage door was open. A neighbor started pounding on my front door telling me my garage was on fire. I opened the door from my kitchen to the garage and seen smoke but it didn't seem major. I grabbed my keys and ran outside to pull my car out of the garage. I started the car and put it in reverse. It didn't want to move so I floored it. Once I got it into the driveway I heard the neighbors yell, "Lady! Get out of the car! The car is on fire!" I jumped out and seen the car was fully engulfed and had spread to the roof of the house. I grabbed the waterhose. It was of no help so I ran into the house to get my children out. Our home and everything in it were a total loss. Also my daughters car. Two of our dogs ran away. The car has been inspected by State Farm. They stated that the fire started in the engine compartment; the right front drivers side. Electrical; most likely the ABS. There were no warnings lights or symptoms. We only had the car for 5 months, it had 8000 miles on it. The oil had been changed at the Hyundai dealership just 5 weeks prior. I have talked to numerous people with Hyundai's that have caught fire, but not a 2022 as of yet. We have signed releases for Hyundia to inspect the car in February but they have not. It is still at the local tow yard. They are also supposed to inspect the house. They have offered to buy the car back but we have not agreed. We believe we are entitled to more compensation than that. I also have videos taken by neighbors and ring doorbells.

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
