I was coasting into a library parking space with my foot off the accelerator. The car accelerated even with my foot on the brake, jumped a curb and was stopped with above ground tree roots. The dashboard should have been lighted up with collision warning indicators and the automatic braking should have engaged. It did none of that. The car was totaled. Nothing was ever checked to see if it was a mechanical error. My insurer totaled the car.

What owners say
The contact owns a 2022 Hyundai Ioniq 5. The contact stated that while driving at 50–60 MPH, the Forward Collision Avoidance and Lane Assist warning lights were illuminated. The vehicle was taken to the local dealer, where the instrument cluster went blank. The dealer was unable to determine the cause of the failure. The manufacturer was contacted and opened a case. The manufacturer sent a technician to diagnose the vehicle. The technician stated that the VCU, battery, ICCU, and high-voltage battery needed to be replaced. The vehicle was repaired, but the failure recurred. The vehicle was taken back to the local dealer, but the vehicle was not diagnosed or repaired. The failure mileage was 19,000.
In stop and go traffic on freeway, car was moving at about 5 miles an hour but car kept moving, collision warning and automatic braking did not activate. Had to turn off car and coast to a stop. Nearly collided with vehicle in front
When driving on the interstate the collision avoidance system will falsely trigger around 5% of the times going under overpasses or road signs. The vehicle rapidly decelerates using regenerative braking.
Involved in a minor collision. Rear ended another car accelerating from a stop light (low speed). Forward collision warning did not activate. Auto braking did not activate. No airbag deployed.
I started my car up right after charging on a rainy day at 2500 miles exactly and got 5 warnings. Check battery, lane assist warning, abs warning, parking brake warning, forward collision warning and bling spot collision avoidance warning lights were on. More or less all these systems triggered a fault. I tried turning it off and on to no luck. As I drove to the dealer my breaks became steadily lighter and lighter with the manual break even clicking at times. My breaking distance was doubled by the time that i got there. Other owners are seeing the same issue. It sounds quite similar to the Kona Electric recall (20V‑748). My car is unsafe to drive.
