In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
Received Hybrid Battery Malfunction and Electrical Leakage Detection alerts two weeks ago. Dealer has not been able to fix. First they said it was the water heater, then they said my radiator was leaking and I need a new one. Estimated 4 additional weeks for repair.
-
Near a roundabout the car in front of me started moving and braked. My car didn’t give any forward collision warning or proximity alert before my car hit the other car from back. The speed was less than 12 mph.
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.
