Methodology & Limitations
Data source: NHTSA Office of Defects Investigation (ODI) complaints database and recalls database. Complaints are consumer-submitted safety reports. Recalls are manufacturer-initiated.
What this is NOT: This is not a reliability ranking. NHTSA complaints measure safety concerns reported by owners, not verified mechanical failures or overall reliability. A car with many complaints may simply have more engaged owners or a larger fleet.
Reporting bias: Luxury brand owners are less likely to file NHTSA complaints (they go to dealers). High-volume, affordable brands get disproportionately more complaints. We focus on model+year level data where the signal is strongest — a 3x complaint spike for a specific model year indicates a real manufacturing issue, regardless of reporting bias.
Time filtering: Default view shows 2012–2026 model years (relevant for used car buyers). Older data has survivorship bias (scrapped cars generate no complaints).
Severity weighting: Problem models are ranked by a severity formula: complaints + crashes×3 + fires×5 + deaths×50. This prioritizes safety-critical issues over minor annoyances.
