Example complaints

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

“The air conditioning and heating controls had not been working and /or working erratically. We took the vehicle to the local dealership for repair. They claimed that they couldn't find any problem. We also asked them to fix the recall item, door switch, and were told there was no recall on our vehicle eventhough we had received notice from GM by mail. On march 14, 2015 I was driving on the interstate when the air conditioner suddenly started working full force. Within 10 minutes I smelled an electric fire and white smoke started coming into the cab from above and below the dash. …”

“The engine quits unannounced and the safety lock dash light illuminates. This can occur anytime regardless of speed. If at highway speed, the car will restart on itself. At low speed, I have to put the tranny in neutral and restart the engine. The dealer cannot find the source of the problem but suspects the ignition switch. The problem is what is causing this issue?”

NHTSA complaint #10557715, filed 2013-12, 72,364 miles

“After filling up the vehicle with fuel, the gas gage goes to zero and the tank empty warning light comes on, after driving about 2 to 3 miles, the check engine light comes on. After driving another 10-15 miles the gas gage returns to showing actual level and the check engine light goes out. However, at about a tank level of about 1/4 the tank is near empty. This erratic malfunction of the gas gage is dangerous.”
