In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
The instrument control cluster the pixels slowly fade in and out cant read any thing that going on with car miles or problems with car.
-
Instrument lights went out, can't see speed or other dash information such as fuel. Rear suspension looses air, car sits to low to drive, body sits on rear tires. Happened while driving city street, tires smoked and are pitted.
-
Started vehicle in my driveway, shifted into drive and instrument cluster goes dark. No power mirrors, seats, no radio, no air.
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.
