In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.

A coolant line fitting that is epoxied into the block became suddenly and completely disconnected. The coolant all flowed out of the leak nearly instantly. The pool of coolant created a hazard for following cars and the motor needed to be shut down immediately and the car towed to a service facility. *js

Coolant hose coupling came lose while driving the vehicle at speed, resulting in loss of all engine coolant. Coolant spilled resulted in temporary reduction of vehicle traction, fortunately without incident. Engine damage due to possible overheating is under investigation.
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.
