To find out the precise warranty coverage:
* Check your original purchase paperwork: This is the most reliable source. Look for the warranty booklet or the sales contract which details the length and terms of the powertrain warranty.
* Contact a GMC dealership: Provide them with your vehicle's VIN (Vehicle Identification Number), and they can access the original warranty information from their system.
Keep in mind that a powertrain warranty typically covers major components of the drivetrain, such as the engine, transmission, and drive axles, but specific components and exclusions are detailed within the warranty agreement itself. A standard powertrain warranty is likely expired at this point (2024) unless it was extended.
