How this page was madeSources, processing, limits, review and changes

Processing

  • Complaints are counted per component. One complaint can list several, so component totals add up to more than the total.
  • Fuel cost = miles per year ÷ EPA combined mpg × EIA weekly price for your region.

Limitations

  • Complaint counts are owner reports, not verified findings or failure rates. There is no sales denominator.
  • Recall campaigns are listed for the model year. Only NHTSA and the automaker know whether a specific car was repaired.
  • Recent model years are still collecting reports.
