Methodology & limitations

Included: 2,548 vehicles across 37 makes and 328 models.
Excluded: Vehicles with no substantive safety dataset (excluded from the index entirely).
Date range: Model years 2015–2025.
Sample size: 37 ranked entities
Calculation: Sum of ODI investigation records across each manufacturer's indexed vehicles.
Data freshness: Dataset last synchronised Jul 23, 2026.

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.
