Limitations

  • Figures are raw counts. VerifyTheVehicle holds no vehicle sales or registration data, so nothing here is normalised into a rate — a high-volume nameplate will tend to show more of everything.
  • Coverage is limited to the 37 makes and model years 2015–2025 currently in the index, not the entire US fleet.
  • Uses each vehicle's top reported components, not the full complaint text corpus, so it slightly under-counts long-tail categories.
