2021 Ram 1500: Problems & Reliability
AVOID2021 Ram 1500: AVOID — 687 owner complaints (1.21 per 1,000 sold), rated on its recalls: 14 campaigns, 4 for fire or crash risk; top issue: engine (277 complaints).
CarWhere's verdict score for the 2021 is 1.74, where 1.00 is a typical 1500 year once complaints are weighted for severity and spread over time on the road; the avoid line is 1.60, so this year clears it by 0.14. Severity drives it: 71% 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 1500 years.
