Owner report 11522056 · 2023-05-15 (May 15, 2023)

I was turning left at an intersection on 5/5/23 and the brakes locked up for no reason. As I entered the intersection the vehicle flashed the automatic emergency braking lights and locked up the brakes as I turned left. The lane in front of me was perfectly clear and the sudden stop fortunately didn't cause the vehicle behind me to rear end me. My wife and I were totally shocked and confused why this happened when there was clearly no obstruction ahead of us or reason to lockup the brakes. This is an absolute flaw and could have caused an accid…

Exterior Lighting	0	0	0	1 ODI 11715738 My bright lights do not go off when oncoming vehicles or vehicles in front of me are close and when they do dim they go on and off. People flash their brights at me causing me not to be able to sleep and this happens even when they turned off of auto. Another item of concern is that the car would lock and unlock and the interior lights would go on and off. This was fixed but it was a line under the front that was not soldered together at the manufacturer is what the Chevy dealership stated. Look up ODI 11715738 at NHTSA ↗	0	0	—	0

While my wife was pulling into park the car and pressing the brake, the car all of a sudden accelerated into the building. Pressing the brake failed to stop the car. No person was in the way of the car so no one other than my wife was at risk of injury. The problem has not been reproduced since the car was totaled. The car was inspected by the insurance for loss but that was it. Police and manufacturer have not inspected the car. No warnings were presented prior to the accident.
