Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I am afraid to drive at night because the head lights are terrible. I couldn't see the tire carcass left on the highway early enough to swerve around it. I hit it with the rear wheel and did approx. 6000.00 dollars damage to the vehicle.”
NHTSA complaint #10948167, filed 2017-01, 7,000 miles“Headlights on this truck have always been weak, distance is not lit up and in rainy weather on the highway is very poor even with fog lights on. The help from the fog lights is minimal. This is a known problem by the manufacturer and is repeated many many times on various GM related owner forums. This is a safety issue and needs to be addressed and corrected by the manufacturer.”
NHTSA complaint #11047397, filed 2017-11, 36,000 miles“The new tow mirrors on this truck have LED blinkers that are so bright you can't tell if someone is coming towards you when you have the blinker on. It's flashing right in your face.”
