Sources & method
Complaint, recall and service-bulletin counts for the 2015 Mazda Mazda6 come from NHTSA's Office of Defects Investigation; the per-1,000 rate divides complaints by published U.S. 2015 calendar-year sales; the verdict is CarWhere’s severity-weighted, time-on-road-adjusted score compared with the model’s own median year. The live complaint feed was unavailable at render, so the complaint count is the verdict engine’s stored count. Complaints are owner allegations, not verified defects. Full methodology.
