Most Complained-About Vehicles: NHTSA Owner Complaints by Make, Model and Model Year, 2010-2025 (Q3 2026 Edition)

Owner complaints filed with the US National Highway Traffic Safety Administration (NHTSA), counted per make, model and model year for model years 2010 to 2025, with the component owners named most. Source: NHTSA's consumer complaint database (copy dated 2026-08-25). Method. Each complaint is counted once per make, model and model year, deduplicated on the complaint number (this removes NHTSA's double filing of tire complaints). Vehicles with fewer than 10 complaints are left out. Components are mentions, so component totals exceed complaint totals; "unknown or other" is not used for the component named most. Limits. Counts are not failure rates (there is no sales data in the file), complaints are voluntary and not verified by NHTSA, and older model years have had more time to collect reports. Files.
