2023 GMC Sierra 3500 problems: engine and transmission complaints and recalls
VERY HIGH COMPLAINT SIGNAL
63%
17 of 27 relevant owner complaints are about the engine, transmission or fuel system
63% of relevant owner complaints filed with NHTSA on the 2023 GMC Sierra 3500 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 84% of the 1,789 model years we track (2010–2023).
Excludes 1 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 61%).
Looking at a specific Sierra 3500?Check its VIN: the full report, quotes about its own engine, and whether its recalls are still open. First report free.
Does the 2023 GMC Sierra 3500 have transmission problems?
Owner complaints say yes, heavily, as a model-year pattern. 17 of 27 relevant complaints filed with NHTSA about the 2023 GMC Sierra 3500 concern the engine, transmission or fuel system (63%), and the largest group is filed under power train (14). For comparison, the 2022 scores 32%. 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.
The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2023 GMC Sierra 3500
Ask the seller whether the transmission has ever been repaired or replaced, and whether the car has shown shuddering, slipping, delayed or harsh shifts, or a whine at speed.
Drive it from a cold start and long enough to warm up. Many transmission faults hide once the car is warm.
Get an independent pre-purchase inspection from a mechanic you choose, and tell them to focus on the transmission.
1 recall campaign on this model year. Whether a specific car still has one open depends on the VIN; the report checks that.
Ask for service records. A transmission already replaced under warranty is a different car from one that was not.

Should I buy a 2023 GMC Sierra 3500?
That depends on the car in front of you, not just the model year. The 2023 GMC Sierra 3500 has an elevated transmission complaint pattern, so treat it as a car that needs proof: service records showing transmission work, a cold-start test drive, and an independent pre-purchase inspection focused on the transmission. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
