Summary Verdict
The 2011 GMC Sierra generally presents as a reliable truck, particularly with its more robust V8 engines. The most commonly cited significant issue is related to the Active Fuel Management (AFM) system in the 5.3L V8, which can lead to costly repairs if not addressed. The 4-speed automatic transmission also has some reported issues with torque converters and solenoids. Electrical gremlins, such as BCM problems, and minor exterior and interior component failures are also noted. However, many owners report positive long-term ownership with proper maintenance. Buyers should be aware of the potential AFM issues and consider a pre-purchase inspection, especially for models equipped with the 5.3L V8 and the 4-speed automatic transmission.
