My front camera that detects the front collision and helps with adaptive cruise control just went dark. I thought maybe it would reset after turning engine off and restarting it, but it didn’t help. Not sure what happened.
Brand new vehicle. Purchased on 10/30/2020. Front collision keeps flashing a red light in the top of dash that shows up in windshield. This happens with no other vehicles on the road at random times. When the vehicle needs to stop or warn you it will not. It will just let you hit a pedestrian or another car. We noticed that the same thing is happening with the rear safety cross traffic.
