Example complaints

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

“Driver's side door will not unlock and will not open. It will not unlock with the lock button or with the key. I have to climb over the passenger seat to enter and exit the vehicle. I looked the problem up online and found that many people have complained about this. It is a safety concern since I will not be able to get out of the car in an accident.”

NHTSA complaint #11190993, filed 2019-03, 180,000 miles

“Low-beam headlamps turned off while vehicle was running. High-beam lights still functional. While driving, my headlights would suddenly turn off without warning, and I'd have to use my high-beams. After a few seconds, they would come back on. This happened a few times, but now the low-beams don't come on at all. There is a recall for this issue, but my VIN isn't included for some reason.”

“While traveling in the fast lane on the garden state parkway I hit a bump in the road, the auto shut off.with a concrete divider along side and autos approaching at high speed, my wife and daughter screaming I managed to get to the end of the divider were I could turn off the auto restarted on 1st try but very scary.”

NHTSA complaint #10618391, filed 2014-08, 160,000 miles

“While driving up a long incline on I-10 vehicle behaved as if the ignition had been turned off and key removed. Ie: engine off, no lights or accessories, no warning lights on dash. Traffic was heavy and my wife was fortunate to safely coast into shoulder. Incident recorded with Buick, have reference number.”

NHTSA complaint #10573586, filed 2014-03, 66,000 miles

“Low beam headlights go out, sometimes they will not come back on until car ignition is turned off and back on sometimes they don't come back on at all, very dangerous, GM has a recall but they say my VIN number is not covered, I have talked to local dealer as well as general motors concerning this issue with no positive response. It appears this issue will be just like the key switch issue, people will have to die before anything is done.”
