The whole-line score for 2020, mostly half-tons: 2020 Ram pickup.
No Lemon Index score: automakers report heavy-duty pickup sales together with the half-ton (one F-Series, Ram or Silverado number), so there is no honest per-truck denominator. These are counts and shares of owner complaints, not failure rates. Complaints: NHTSA owner complaints filed under the truck's 2500/3500 (F-250/F-350) names, all years filed, one per complaint number. Engine: decoded from the complaint's VIN (position 8 is the engine code) with NHTSA's vPIC decoder. Complaints filed as just “Silverado” or “Sierra” are left out (they mix 1500s and HDs). Older trucks have had more years to collect complaints, and popular years draw more because more were sold.
