2023 GMC Sierra 2500 problems: engine and transmission complaints and recalls
66% of relevant owner complaints filed with NHTSA on the 2023 GMC Sierra 2500 are about the engine, transmission or fuel system. Well over half of everything owners reported is the drivetrain. That is a severe model-level pattern; every model year we track at this level has a documented failure behind it.
Worse than 88% of the 1,790 model years we track (2010–2023).
Does the 2023 GMC Sierra 2500 have transmission problems?
Owner complaints say yes, heavily, as a model-year pattern. 21 of 32 relevant complaints filed with NHTSA about the 2023 GMC Sierra 2500 concern the engine, transmission or fuel system (66%), and the largest group is filed under power train (20). For comparison, the 2022 scores 30%. On a test drive, check for shuddering, slipping, delayed or harsh shifts, or a whine at speed. 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.
