“I bought my 2021 hyuandai elantra on September 7 2023 almost 2 months ago and the emergency braking system comes on pretty often while driving my vehicle on the road and freeway so the brakes will lock on me whenever the car is in drive which could cause a serious crash and probably cause damage over time to brake pads and other things this problem has occurred over 5 times within 2 months”
NHTSA complaint #11558126, filed 2023-12“Forward Collision warning system continues to engage dangerously and inappropriately, almost causing me to be hit from behind, as I always leave plenty of room in front. This is very scary and very dangerous. Software updates have not remedied the situation. Hyundai motors seems completely uninterested.”
NHTSA complaint #11540066, filed 2023-08“Twice now when starting the car all the driver safety systems will show a warning that they are not working and the message is that the car is not save to drive. A bunch of warning signs will go off and the wheel locks. The brake system has also locked up. I captured it on video, but it won’t let me upload it here.”
NHTSA complaint #11464308, filed 2022-05“I was traveling in the rain and a CHECK FORWARD SAFETY SYSTEM warning appeared on my dashboard. There was nothing in front of me to set that off. I notified the dealership and they said it was an alignment code and must have gotten hit.( Which I doubt) so wasn't covered under warranty.”
NHTSA complaint #11523885, filed 2023-05“One day I was on the highway driving and the front collusion safety warning appeared. I thought the warning went off because the sensor was dirty due to dead bugs. However, I pulled over and the sensor did not appear dirty. After awhile the sensor went off on its own. Then a few weeks late the front collusion safety warning appeared again while I was driving on the highway. The warning has not fixed itself. I cannot use my cruise control. …”
