Example complaints

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

“I have had trouble with this ignition for years, having to jiggle it to start the car, a key tip broke off from trying to turn it. I also was never contacted about fuel line recall that I had to have repaired and paid for. My engine has also lost power and the engine light has been on for years and they don't know why? I don't feel safe even driving this piece of junk to the dealer.”

“I started my car up and it sounded extremely rough and the check engine light came on. I took the car to a service center to get oil changed, coolant changed, fuel system cleaned and to get an overall check done. They were unsure of the issue and I took the car to the dealership where a diagnostic test was done and it read that there was an issue with the timing chain. After reading on here and online I see this is a common issue with this car.”

“I need to know why your system shows no recalls for my vehicle using the VIN number, but has (7) recalls if I use year/make/model, the system should allow me to run the VIN, see all recalls, and even report with proof if the recall is complete, like a check list. Your system is useless if the manufacturer is not agreeing to the recalls under the year/make/model and assigning the recalls to the VIN to grant approval to dealers to repair, a dealer will not complete a GM recall unless GM approves of the recall for a particular VIN. …”

“After driving my vehicle for approximately five miles, I placed the car in park and turned the key back to turn the vehicle engine off. The key turned back and I was able to take the key out, but the engine did not turn off. I brought the vehicle to a GM dealer and was told the cause of this issue was a faulty ignition lock cylinder assembly. The dealer replaced the lock cylinder, which was apparently not under warranty, but could be related to the recall that GM is now issuing, revolving around the faulty ignition. …”

“After my day of driving I pulled into my driveway at my home and put my car into the park gear and continued to remove my key--the key would not turn to off position. It had locked into place. I had to call my husband to come home and help me. He too tried. It would not turn to the off position. The only way we got the car to turn off the engine was to disconnect the battery cables. The key stayed in the on position. I had to contact the GM dealer the next morning -- I had to have my car towed to the dealership in frederick, maryland. …”
