My car automatically braked in the middle of an intersection and caused my vehicle to be rear-ended. This was the third time automatic braking engaged when it should not have been. In the most recent incident on [XXX] I was injured and had to have medical attention. I googled automatic braking and there were many reports of automatic braking being deployed when it should not have been.

Nov 27, 2024Transmission & drivetrainBrakesCrash

While sitting in stopped traffic on the interstate in the dark in the rain on 11/25/2024 my car was in drive; my foot was on the brake. Twice the car rolled away despite my attempts to brake or put the car in Park (I shoved the shifter into Park and the car continued to roll). I rolled into the back of a semi because I could not get my vehicle to stop. This had already been noted as a problem with 2024 Tucsons, yet your search engine tells me there are 0 unrepaired recalls for my car. I want to call this out as an unrepaired recall. I have left it with the Hyundai dealer at the moment. They tell me if they cannot make the problem happen for them they won't do anything to fix my car. This is a dangerous situation for me and for anyone with a Tucson that may have the same problem.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2024 Hyundai Tucson Fuel Cell verdict →
