Data study

Most Complained-About Used Cars

Owner complaints filed with the NHTSA are a window into the problems drivers actually experience after the sale. We ranked every model in our database by total complaint volume for its most recent year. Higher volume can reflect real trouble spots — or simply how many of that model are on the road — so we show recall counts and scores alongside for context.

How this was compiled

Recall and complaint counts come from the NHTSA (National Highway Traffic Safety Administration) public API — the same federal database regulators use — for each model's most recent year in our database. The reliability score (0.5–10.0) combines brand-tier reliability, recall volume and severity, owner-complaint volume, and documented known issues.

This is a model-level estimate from public data, not a judgment on any specific vehicle. High-volume, popular models attract more recalls and complaints simply because more of them are on the road. Always get a pre-purchase inspection. Full methodology →
