Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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.”
