In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
There have been several false blind spot monitoring alerts since I received vehicle. It seems to get worse with time. Now on freeway trips it’s almost constant leaving no trust with alerts
-
Phantom Blind Spot Monitoring occurred while driving 70-73mph. Right driver side blind spot turns on for almost 5 minutes with no other vehicles around. Switching lanes causes lane departure warning system to activate.
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.
