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

Driving on highway long distance on sunny days the radar becomes blocked disabling critical forward safety functions and cruise control. Numerous times this has caused a near collision due to the automobile malfunctioning. Many times my cruise control has just stopped working and my vehicle has rapidly decreasing speed, causing people behind me to have to slam on their brakes. My vehicle has also automatically braked on the highway when there was no one in front of me. these are just two incidences that have nearly resulted in collisions on the highway. This has been occurring since I purchased the vehicle in September 2022. Unfortunately, dealership has not been able to duplicate what has occurred.

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.

I was pulling out of a parking lot when my auto-braking activated. There was absolutely nothing anywhere around my car. I was entering a 2 lane road with zero traffic on it at that moment. When I pressed the gas pedal the brakes stayed locked. I quickly pressed the brake pedal at which time it released the brakes. I was then able to accelerate freely.

The automatic emergency braking has numerous false alerts, several times each day. The problem seems to be worse when a vehicle travelling the same direction in a different lane slows. The problem also appears when the Tucson's own shadow shifts directly in front of the car near sunrise and sunset when longer shadows are present. The car will brake hard though there is no risk of forward collision. This creates a danger as vehicles behind my own cannot anticipate this sudden hard braking, thus increasing the risk of a rear end collision.

I bough my new suv around 4 to 5 months ago. Since i bought it and this only happened about 3 times. I was on highway and with no cars on the highway and myself going 70 the collision in the front came on and emergency breaking saying im about to hit something. But nothing was there. This also happened when i reversed too. The brakes would slam on saying collision. Also when im driving in a straight line the lane detection moves me in the middle of the road to the white lines are under my car and i am driving on 2 lanes. It keeps trying to move me over to other lane even though im in the correct lane. I have almost got into like 7 accidents. I already brought my car to the dealer and they told me there is no fix for that. I am not the first to come in saying the same thing.

Purchased this vehicle 12/2021 it hesitated on pick up but drove good after that nice look but the headlights are bad at night. First month I had a bad scare as when attempting to stop the brakes gave out, I had to pump multiple times to get the car to stop, this happened again about 1 month ago. On 10/10/22 while attempting to park in my driveway which is on a hill the car did not want to accelerate when pressing the gas and many lights turned on the dashboard. Warning, check engine, brake, front collision, etc. I have not had any accidents for the collision light to be on anyways. I turned the car off and restarted it I even disconnected the battery but still nothing the car has power because it does turn on and the lights, radio work but it just would not accelerate. I'm on a very dangerous hill lucky this happened late night when not much vehicle traffic. The next morning 10/11/22 around 10 am Hyundai came to pick up the vehicle. I passed by that day around 4 pm to see what was going on. They had not checked it yet which is understandable we ask the guy when he thought it would be checked out and he responded that towed vehicles take longer to be checked, we asked for a loner and they said they did not have. Saturday 10/15/22 went again, the car was still in the same spot not looked at yet, today 10/19/22- 1 week and 1 day they have not checked the car and we were told they had a lot of cars to work on and we were far down on that list. So basically they will probably take 2-3 weeks to even look at it and if any parts are needed it would probably take another month and without a loner. So we the paying clients have to figure it out. This is very unacceptable not to mention how scary it was for the car to completely give out on a hill thank god no one was driving or walking behind me. I have been driving for 29 yrs and have never experienced something like this. This car can potentially be deadly specially to a new driver.

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.
