Methodology: Rankings are based on NHTSA complaint data, safety ratings, and EPA fuel economy figures. Reliability verdicts use within-model percentile scoring — comparing each model year against other years of the same vehicle and against the overall dataset. This prevents high-volume models from being unfairly penalized for having more total complaints.
