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

While driving 50-60 mph wheels locked up, causing vehicle to veer from side to side, finally spun around. Vehicle was towed to dealership, it was determined that differential had locked up and needed to be replaced. *ak

I have subframe damage, in the trunk it's most visible with the carpet out, i can see the spot welds have popped, cracked, broke free, whatever. Thus can cause a massive risk to as if anymore pop the differential could possible tear next the bracket that holds it up.

The consumer states that the clutch pedal squeak, and was lubed, but it it started squeaking again. *scc
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.
