CAUTION2021 Ram 2500: CAUTION — 109 owner complaints, rated on its recalls: 8 campaigns, 4 for fire or crash risk; top issue: electrical system (35 complaints).
CarWhere's verdict score for the 2021 is 1.28, where 1.00 is a typical 2500 year once complaints are weighted for severity and spread over time on the road; caution starts at 1.25 and avoid at 1.60. Severity drives it: 67% of those complaints report a crash, fire or injury or involve a safety-critical system (engine, powertrain, steering, brakes or fuel). Its raw count is below the median year, but it has been on the road only about 5 years, so complaints are arriving faster than for older 2500 years.

What to check on a used 2021 Ram 2500
Electrical system (35 complaints on the 2021): test every light, window, lock, the infotainment screen and the charging system, and have the car scanned for stored fault codes.

Powertrain / transmission (25 complaints on the 2021): test-drive from cold through every gear and feel for slipping, harsh or delayed shifts and shudder; ask whether the transmission fluid has been serviced.
