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

Cars acceleration causes me to be unable to pick up speed it decelerates up hills small or latg ramps cats constantly fly pass to avoid a multi car pile up it’s very dangerous!
-
I believe the passenger seat occupant sensing and airbag issues from recall 16V507 have not been fixed. I am still having issues related to it, even though I had it fixed.

Car been having coolant leaks, & electrical problems , windows stop working then start working again , & overheating even after repairs, car won't start now it shut off while in motion
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.
