“When turn the car off and remove the key from the ignition, there are two speakers that continue to make static noise, whether I have opened the door or not. If I bump or hit the center console it will make the speakers louder or turn off. The check engine light is on for multiple codes, and I have worn out shocks. The shocks should make me feel as if I am gliding, bur I feel and jerk to every bump.”
NHTSA complaint #11317442, filed 2020-03, 185,000 miles“Driving along at 30 MPH and stepped on gas to speed up to 45 MPH which was the new speed limit, when tried to accelerate I had nothing.

It ran fine the whole trip and the nothing. Thx”

NHTSA complaint #10822900, filed 2016-01, 35 miles“There is a defect with the vehicles electronic control module. This is not something that the consumers are causing, this defect causes the vehicle to shut off at random times, and will not start back up for several minutes. This is extremely dangerous. I have searched hundreds of forums on a fix for this only to find hundreds of thousand of people that are dealing with the same thing. Chevy needs to step up and take responsibility for this! I am sure there have been lives lost because of the vehicles shutting off on busy highways, and streets. …”

I was in the middle lane and traffic was vicious, I turned on my hazards and attempted to try and push on the gas. I car came to a stop but the engine was still running, it felt like I was in neutral but I was clearly in drive. …”
