What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Both frontal air bags failed to deploy, and the safety belt failed to keep the contact secure in the seat, causing the contact to be thrown over the steering wheel and strike the windshield. The contact incurred internal abdominal injuries as well as head lacerations. There was a police report taken.
Spare tire completely rusted out, unable to get down. Not sure if this is a recall issue but apparently common for this vehicle
So the hydraboost is failing and my truck is pouring an insane amount of power steering fluid from hydraboost system. When researching this problem for my year make and model the hydraboost recall pops up but when calling chevrolet they want to do nothing. When its apparent my truck is affected by trash parts.
The shift lever position indicator located in the instrument panel cluster does not illuminate therefore, I don't know what gear the vehicle is in. It seems like a safety issue to me. It occurs when I start the vehicle, am moving and when the headlights are on.
The shift lever position is not illuminated. There is another recall for this same issue but the company will not do anything. I turn the vehicle on and cannot tell what gear I even am in,
At 80k I put my truck in reverse and heard a clunk sound and immediately it wouldn't shift gears anymore. I went and had the transmission rebuilt which lasted roughly 10k more. Now, the truck won't shift yet again and the filter was changed and the rear output seal.
Started to take off it started slipping then quit pulling completly.puet it in all drives 1,2,3, & d nothing happened cut engine off put it in drive it started out like nothing happened for short distance then same thing again.
I was told by a gm dealer how my vehicle is rusted excessively with the undercarriage and the quarter sills that have a rust through hole about 3 inches. I've opened a case with gm and they stated its out of warranty.
