In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
I was trying to roll down the windows for my wife. The windows would not roll down at first. I checked to make sure that the window was not lock and it wasn't. After a few minutes the window finally rolled. Down. This has happened on several occasions.
-
Fuel sending unit failed so i could not tell how much fuel i had. GM would not replace it. They sent me a letter that they had problems with them all. And would pay for half of the repair. That is unacceptable.
-
My fuel gauge stopped working correctly, when i fill it up it will read empty. After about several hours the gauge will start to go up. Spoke to chev. Dealer and was told that time has passed for them to fix at on charge to me. I only have 86968 miles on it this should be changed to cover more time
How to read this page
Every figure comes from the National Highway Traffic Safety Administration's public complaint database, which holds every safety-related defect complaint filed by owners since 1995. We refresh it monthly and count each complaint once per component it names. Data through September 6, 2026.
NHTSA only accepts safety-related complaints. Rattles, paint, infotainment bugs and other annoyances are under-reported here, so this page is a map of what fails in ways owners consider dangerous, not a full reliability score.
Counts are raw. Use the year-over-year shape and the component mix, not the absolute numbers. Where a component maps to parts we stock, the row links to that category filtered to the year you are viewing. Air bag and seat belt complaints link to the recall checker instead, because those repairs are almost always covered.
