Example complaints

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

“Heater motor continues to run after the switch is turned off, the blower only works randomly. I understand there is a recall for this issue but my VIN is not included. This seems to be a problem in a number of different GM vehicles. There is a chance of electrical fire with the being able to run with the switch off also the report would not pull a list of parts nor would it permit me to type in the parts: heater motor blower resistor, and wiring connectors.”

“The wire that connects the airbag person in the seat switch breaks when you put (slide) the seat all the way back. They know this and have not recalled the truck! They will not and are not going to pay to fix it. The airbag will not deploy when needed, is this a safety recall?”

NHTSA complaint #10306185, filed 2010-02, 50,000 miles

“I continue to be annoyed by a condition I experience with the Gmc vehicle I purchased new three years ago. The problem is one that the dealer does not have a remedy for. The specific problem is that when the vehicle is parked overnight or when it is parked in the shadows, the instrument panel is not lighted when one drives away sometimes for periods of up to thirty to forty-five minutes. This becomes particularly irritating in the case of the radio which cannot be read from the driver's position. …”

NHTSA complaint #10378175, filed 2011-01

“The contact owns a 2007 Gmc Sierra. The contact stated that the heater failed. The motor would operate but no heat would emit from the vents. The vehicle was taken to the dealer for inspection where they stated that the wiring was overheating and the wiring harness needed to be replaced. The vehicle was not repaired. The manufacturer was notified and advised that the vehicle was not included in any recall. The failure mileage was 95,000.”
