Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“When it is dark outside and you put the vehicle in reverse, the lights next to the back up camera causes the screen inside the car to show bright white. There is no way to shut the screen off when in reverse. I have turned the brightness all the way down but it is still very bright making it impossible to see your surroundings safely. I have almost hit a tree and drove into a ditch trying to reverse at dark. This is very dangerous and needs to be fixed.”
