This section outlines the Emission Warranty that GM provides for your vehicle, in accordance with the U.S. Federal Clean Air Act. Defects in material or workmanship in GM emission parts may also be covered by the 3 year/36,000 mile "Bumper-to-Bumper" coverage. There may be additional coverage on GM diesel engine vehicles. In any case, the warranty with the broadest coverage applies.
What Is Covered
The parts covered under the Emission Control Systems warranties are listed under "Emission Warranty Parts List" later in this section.
What Is Not Covered
The Emission Control Systems warranties obligations do not apply to conditions resulting from tampering, abuse, neglect, or improper maintenance; or any other items listed under "What is not Covered" in the New Vehicle Warranty. The "Other Terms" presented in the New Vehicle Limited Warranty also apply to the emission related warranties.
How to Determine the Applicable Emissions Control System Warranty
State and Federal agencies may require a different emission control system warranty depending on whether the truck has a light or a heavy duty emission control system. Do the following to determine your truck's system:
- Locate the Emission Control Label. The label will be attached inside the engine compartment or on the underside of the hood, the engine air cleaner housing, or on the engine.
- The language found along the bottom left side of the label will describe the type of emission control system (i.e. Light Duty or Heavy Duty).
