"Stands out" = 40 or more complaints naming that system and at least twice the model's quiet (lower-quartile) year, or twice the share seen across every vehicle of that model year. Newer years have had less time on the road. "Quiet" ranks only years with 7+ years on the road and 20+ complaints. NHTSA data through November 2026.
