Methodology & source

All figures come from the U.S. National Highway Traffic Safety Administration (NHTSA) public APIs: the Office of Defects Investigation complaint database, the recalls database, and NCAP safety ratings, retrieved September 7, 2026.

Complaints are self-reported by consumers and are not verified by NHTSA or by this site. A single complaint may cite multiple vehicle systems, so system mentions can sum to more than the complaint total. Complaint volume is influenced by fleet size, media attention, and recall notices, and is not by itself a measure of defect rates.

This site is not affiliated with NHTSA or any manufacturer. Nothing here is repair, purchase, or legal advice. For your specific vehicle, use the official NHTSA VIN lookup and consult a qualified technician.
