Ranked by total NHTSA complaints per model year (not adjusted for units sold). A zero means no owner reports in the current NHTSA data, not that the car is problem-free. "Severity" is a harm-weighted index of those complaints — higher means a greater share involved crashes, fires or injuries. Complaint-volume percentiles vs. segment peers are computed separately and appear on each year's page.
