2021 Chevrolet Silverado 3500 problems: engine and transmission complaints and recalls
35% of relevant owner complaints on the 2021 Chevrolet Silverado 3500 are about the engine, transmission or fuel system. That is elevated. Worth an independent inspection before you commit to one.
Better than 62% of the 1,790 model years we track (2010–2023).
Excludes 3 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 33%).
Does the 2021 Chevrolet Silverado 3500 have transmission problems?
More than most. The pattern is elevated rather than severe. 13 of 37 relevant complaints filed with NHTSA about the 2021 Chevrolet Silverado 3500 concern the engine, transmission or fuel system (35%), and the largest group is filed under power train (7). For comparison, the 2020 scores 50% and the 2022 scores 28%. 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.
