CarWizz data study
Not every complaint is equal. We counted the owner complaints that NHTSA flags as involving an actual fire, across roughly 500 used-car models, and ranked the 20 with the most. In several cases the fires trace back to a single model year.
Published July 2026. Source: NHTSA fire-flagged complaints (US public record).
Key findings
Total NHTSA fire-flagged complaints, summed across all model years. Click a car for its owner report, or the year for that year's reliability breakdown.
NHTSA tags individual owner complaints when the reported incident involved a fire. We counted those fire-flagged complaints across roughly 500 used-car models in the CarWizz database and summed them per model across every model year on record (1996 to 2025). A fire report is an owner-submitted account, not a confirmed vehicle defect, but the fire flag makes this a safety-critical subset rather than general grumbles.
The caveat:like any raw count, totals partly track how many cars were sold and how long a model has been on the road. Where this ranking is more useful than raw complaint volume is the single-year concentration: when most of a model's fire reports land on one model year, that usually reflects a specific defect (and often a recall), which the per-year links break down.
