GMC Sierra 2500: Years to Avoid and Best Years (Engine & Transmission)
GMC Sierra 2500 problems by model year, from 1,020 owner complaints filed with NHTSA (sold as the Sierra 2500HD). For each year: the share of complaints about the engine, transmission or fuel system, how many there were, and the recalls.
Worst years to avoid: 2023 (66%, 21 drivetrain complaints), 2021 (48%, 19 drivetrain complaints) and 2020 (47%, 35 drivetrain complaints). 10 of the 14 GMC Sierra 2500 years we score have an elevated engine, transmission or fuel-system complaint share; 1 of them is at the very high level (60% or more), where every model year we track has a documented failure behind it.
Best years on this measure: 2010 (11%), 2016 (28%) and 2022 (30%). 2010 and 2022 rest on fewer than 60 complaints, so treat them as provisional. A low share means owners complained about other things more than the drivetrain, not that nothing ever fails.
The sharpest change between consecutive years is from 2022 (30%) to 2023 (66%), up 36 points. The complaint pattern shifts at that year, so check which year the car in front of you is.
By raw volume, the 2017 drew the most drivetrain complaints (41 of 293 across the scored years). Volume also tracks how many were sold and how long they have been on the road, which is why the share, not the count, sets the verdict.
Engine and transmission complaint share, 2010–2023
Share of relevant owner complaints about the engine, transmission or fuel system. 33% is elevated, 40% high, 60% very high. A dash means too few complaints to score.
