Example complaints

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

“Air bag module not responding and is dangerous due to the fact it could deploy at a random time while driving. The air bag light stays on after the vehicle is in motion causing a potentially dangerous incident. Also hairline cracking in the radiator due to the plastic top of the radiator tank rubbing on the vehicles frame.”

“Was doing a frame inspection on my hummer h3. Turns out the rear left frame rail is completely rusted through. And there are parts hanging on by a thread. I have found many complaints online about rust in this exact spot( rear left frame). I believe this issue should be dealt with immediately. Someone could be killed. The car is not that old and no other car of this age and mileage has this amount of rust penetration through the frame. GM needs to be held accountable. THIS IS A MANUFACTURING DEFECT.”

“I rec'd a safety recall notice 8/15 for 2009 H3 recall# 15042 or 15v421 (2 different # in letter) from Hummer . The connector module that controls blower motor speed may overheat. If this condition occurs, there is the risk that the heat generated could melt the plastic surrounding the connector module, which increases the risk of a fire I called dealer-and told GM has no fix for this issues (I call every few weeks) I called GM direct that said they don't have the parts yet to fix it. …”

“Gm passlock system very randomly engages or is trigger without warning when simply turning the key in the ignition to start the car. However, the attempt to start the vehicle is not successfuly which causes the inability to power the vehilce for 10 minutes. There are numerous Hummer H3 owners with the same issue. The GM dealers are no help in resolving the problem. In fact I feel as if I'm making it up. I've tried 3 GM dealers now between louisiana and texas. The only thing are expensive guess at the problems the dealers state they can try to resolve their very own made GM system. …”
