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. Complaints pile up over a car's life, so the last few model years look quiet mostly because they have had less road time — we mark them "still new" rather than treating them as lower-complaint standouts.
5 model years show zero owner complaints in the current NHTSA data. That can reflect low reporting volume, not a clean bill of health: 2016, 2022, 2023, 2024, 2025.
