2021 Ram 2500 problems: engine and transmission complaints and recalls
53% of relevant owner complaints filed with NHTSA on the 2021 Ram 2500 are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 70% of the 1,790 model years we track (2010–2023).
Excludes 8 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 49%).
Does the 2021 Ram 2500 have engine problems?
Owner complaints say yes, as a model-year pattern. 53 of 100 relevant complaints filed with NHTSA about the 2021 Ram 2500 concern the engine, transmission or fuel system (53%), and the largest group is filed under engine (26). For comparison, the 2020 scores 44% and the 2022 scores 51%. On a test drive, check for stalling, loss of power, rough idle, oil consumption or a check-engine light. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.

2021 Ram 2500 transmission recalls
Yes. NHTSA lists 1 recall campaign on the 2021 Ram 2500 involving the engine, transmission or fuel system, out of 8 in total. A recall is the manufacturer admitting a defect and paying to fix it; whether a specific car still has one open depends on its VIN, which the full report checks.
