Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My radio volume goes nuts and the controls go unresponsive, The unit brings the volume up to max I can not hear emergency crews if they are using the siren. This also creates a safety issues as now I am taking my eyes off the road to try and stop the problem. The infotainment system is failing yes the truck is available for inspection. I have taken video of the problem and sent it to the dealer. …”
NHTSA complaint #11439172, filed 2021-11“I was sitting at a traffic light stopped when all of a sudden the truck tried to accelerate, I stood on the brakes to get it to stop then all of a sudden it was like i was giving it gas again and I hit the car in front of me again but harder the second time.”
NHTSA complaint #11549877, filed 2023-10“The truck has only 40K miles on it. I was checking under the hood when without notice the heed dropped hitting me in the head and pinning my hand under the hood thus trapping me there. A rescuer released the hood release lever so I could escape. I had a lump on my head and my hand was /wrist was bruised. I am on blood thinners so I consider myself lucky. The stanchions that hold the hood open suddenly failed and will not hold the hood open.”
NHTSA complaint #11554567, filed 2023-11“2021 Chevrolet Colorado shifter would not work properly When put into park it would not allow me to turn the key all the way to the left and therefore would not allow me to remove the key. So my truck is only 3 years old, I keep up with preventative maintenance and this should not have happened. It just cost me $518.97 to get repaired. My husband and a friend both have Chevrolet (Malibu and Blazer) and both also have shift problems. Seems to me that Chevrolet has issues with their shifts.”
NHTSA complaint #11600145, filed 2024-07“I have 2021 Chevy Colorado pickup truck. Put the truck in park and unable to turn off and remove the key. This is the third time this has happened this week . The first two times I moved the shifter from park to drive and back and it released. The last time I had to sit in my drive way for twenty minutes with the truck running before I could turn the key to shut off the truck. This is a very dangerous situation if there was every an emergency and not being able the shut off the truck.”
