In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
Recall was ordered in oct 2017 and has still not been remedied. Safety recall 17v-676. I believe we have been patient. We cannot sell the car as is because it can catch fire.

All exterior lights comes on when the car is off, and now the car stays on when the key out out of the ignition. The recall was fixed before about the lights but they started back again i just got the car and i can't even drive it without the battery dying if i go to work or even the store

The smell of electircal fire and thick black smoke poored out the left side of my stearing colum. Flames started to shoot out and enguffed my bmw to nothing!
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 30, 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.
