Example complaints

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

“Ignition switch is failing, causing stalls, and flashing warning lights. Warning lights came on for just a second or 2 today while I was driving at highway speed. It stopped at a stop light and I had to start it. It killed in a garage, turning off the highway into a driveway, and so on. Evidently this is a problem in GM cars.”
