In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
The fan blower for heat and air wouldn't cut off even with the key out of ignition. Also two coil packs went out within a month.
-
Driving at a low speed down hill on a city street, with the car in the drive position, the car stalled. This happened again driving on a flat service of a parking lot of a shopping center. Again, with the car in the drive position going at a low speed the car stalled.
-
Gas gauge failed to read the correct fuel level in the tank. Thankfully, we noticed before running out of gas on the highway. Fuel gauge would float between 1/4 and 3/4 tank so you couldn't tell how much gas you had.
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.
