How to Read These Counts: complaint counts are owner reports to NHTSA, not failure rates. Older and higher-volume vehicles accumulate more reports, and counts are not adjusted for vehicles sold - no per-sales rate or reliability ranking is shown, because the public data does not support one.

Data as of October 30, 2026. Sources: NHTSA Office of Defects Investigation complaints, recalls, and investigations files (U.S. Government public domain). DefectRecord is not affiliated with NHTSA or any manufacturer. For your specific vehicle, use NHTSA's VIN lookup. Report an error.
