Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.
