What 266 owners told NHTSA about the 2025 Hyundai Tucson Fuel Cell

Under two occasions I was driving on the highway at a safe distance from the car in front of me and my car emergency braking system triggered and went off and caused my car to stop in the middle of the highway. This caused a collision behind me. There was no reason on either occasion for the braking to bring the car to a hault.

At least 5 times now when no car was breaking extremely close to me or when I gently touched the breaks the automatic emergency breaking kicked in and slammed the car to a stop. Twice the car behind me had to swerve out of the way and hit another car causing 2 accidents without my car being involved. Once it caused me to hit my head on the steering wheel. This function is more destructive and dangerous than helpful. At no time should my car go from 70 to 0 in a second for no reason, but with this it does. Got the car in the March 2025 so 5 times in 7 months.

Forward collision warning automatic braking caused car behind me to rear-end me. This is the first accident but third time the automatic braking unnecessarily caused an issue. The car in front of me was far enough away that it did not require an auto-brake.

4th occurrence of the forward assistance warning system activating when we were at a slow speed with plenty of room to stop and the brakes engaged suddenly to stop the car and today someone slammed into the rear of our car. This is extremely frightening and should never happen at slow speeds when there is ample time to stop. My husband doesn't even want to drive this car again as he's afraid we may be killed. I see on the reddit site that this is happening to others too. Hyundai must fix this issue ASAP. You can temporarily stop this from working but everytime you stop & turn off car you must do it again. Police were called & report filed. We have to get our car fixed now.

I am filing a complaint regarding a serious safety malfunction in my 2025 Hyundai Tucson’s forward collision sensor, which caused an accident. I have owned this vehicle for only two weeks, and I believe this issue poses a risk to myself and other drivers. On February 25, 2025, while driving, the car in front of me stopped and made a U-turn. There was no imminent risk of collision, yet my Tucson’s forward collision sensor erroneously activated and engaged the automatic braking system. This caused my vehicle to come to an abrupt stop, resulting in a rear-end collision. I have documented the incident, including photographs, a police report, and insurance documentation, which I can provide upon request. This malfunction is extremely concerning, as a feature designed to prevent accidents instead directly caused one. If this issue exists in other Hyundai Tucson vehicles, it presents a severe hazard for drivers. I urge NHTSA to investigate this as a potential safety defect, determine if other similar complaints exist, and assess whether Hyundai needs to issue a recall or software fix. I also need guidance on whether there are any known remedies or if I should take my vehicle to the dealership for inspection. This issue must be addressed before it leads to more accidents. Please let me know if further information is needed.
