2023 GMC Acadia: engine and transmission complaints
HIGH COMPLAINT SIGNAL
55%
21 of 38 relevant owner complaints are about the engine, transmission or fuel system
55% of relevant owner complaints filed with NHTSA on the 2023 GMC Acadia are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 73% of the 1,230 model years we track (2010–2023).
Excludes 4 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 50%).
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.

Oil leaks from the timing cover on the top and bottom.

I find the location of the lower gear shifters + and - to be physically far away from a driver's normal reach, making a driving hazard. If you want to change gears as is typical in mountain driving in steep descents, the driver has to lean awkwardly away from all mirrors and standard driving position making it a potent…

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2023 GMC Acadia
Ask the seller whether the engine has ever been repaired or replaced, and whether the car has shown stalling, loss of power, rough idle, oil consumption or a check-engine light.
Drive it from a cold start and long enough to warm up. Many engine 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 engine.
4 recall campaigns 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 engine already replaced under warranty is a different car from one that was not.
Have the VIN?Paste it and get the full report for that car. First report free, then a 30-day pass covers a whole car search.
Experimental model-level information. This is not a vehicle inspection, vehicle-history
report, financial advice or purchase recommendation. It describes patterns across a model year, not the condition
of any individual vehicle.
