About this data — Complaint figures on this page are consumer reports submitted to the National Highway Traffic Safety Administration (NHTSA), a U.S. government agency. NHTSA does not verify individual complaints; a complaint is not proof that a defect exists, and counts reflect what owners chose to report, not confirmed failure rates. Recall information comes from official NHTSA safety recall campaigns; recall repairs are free at authorized dealers. Always check your specific vehicle by VIN at nhtsa.gov/recalls.
