Sources & method
Safety Signal starts every model-year at 100 and subtracts points per open NHTSA recall campaign by severity: critical 15 (fire risk, park-outside or do-not-drive advisories), high 8 (brakes, steering, airbags, loss of drive power, structure, battery), moderate 6, minor 3 (software, labels, lighting fixed by an update). Floor 35. A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60, otherwise F. Complaint counts and NHTSA crash ratings are shown separately and are not blended into the grade.
EPA figures come from fueleconomy.gov vehicle records. Recalls, complaints, investigations and crash ratings come from NHTSA's public flat files, refreshed weekly.
