In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
Consumer complained about a brake problem. While driving on highway brakes were slow to stop vehicle. When driving around town brakes worked fine. Also, windshield wipers operated poorly, power steering worked intermittently. *ak
-
Transmission chattering, feels loose, feels as though it's trying to fall out on take off. Rear differential / drive shaft. Rear end is being damaged by transmission not proper. Missed the lemon law by less than 6000 miles.*ak
-
The windshield wiper motor doesn't work most of the time. It makes a wining sound when you try to turn them on. To make them start working i have to tap on the windshield wiper motor. *jb
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.
