The check engine light keeps coming on. We had spark plugs changed and still keeps miss firing. We are unable to switch between drive modes smoothly. We have taken in for service numerous times.

-
the electrical system failed on four separate occasions. Once in heavy traffic on Route 130, NJ; anther with a young grandchild in the car. I am afraid to drive it
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.
