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).
Federal Emission Control Systems
Federal Warranty Coverage
Both the Emission Defect Warranty and the Emission Performance Warranty described below begin on the date the vehicle is first delivered or put into use and continue as follows:
| • | Light Truck equipped with Light Duty Gasoline Engines |
| - | 2 years or 24,000 miles and 8 years or 80,000 miles for the catalytic converter, the vehicle/powertrain control module, transmission control module, or other onboard emissions diagnostic device, including emission-related software, whichever comes first. |
| • | Light Duty Truck equipped with Heavy Duty Gasoline Engine |
| - | 5 years or 50,000 miles, whichever comes first. |
| • | Light Duty Truck equipped with Heavy Duty Diesel Engine |
| - | 5 years or 100,000 miles, whichever comes first. |
Emission Defect Warranty
GM warrants to the owner the following:
| • | The vehicle was designed, built, and equipped so as to conform at the time of sale with the applicable regulations of the Federal Environmental Protection Agency (EPA). |
| • | The vehicle is free from defects in material and workmanship which cause the vehicle to fail to conform with those regulations during the emission warranty period. |
Emission related defects in the genuine GM parts listed under the Emission Warranty Parts List, including related diagnostic costs, parts and labor are covered by this warranty.
Emission Performance Warranty
Some states and/or local jurisdictions have established periodic vehicle Inspection and Maintenance (I/M) programs to encourage proper maintenance of your vehicle. If an EPA-approved I/M program is enforced in your area, you may also be eligible for Emission Performance Warranty coverage when all of the following conditions are met:
| • | The vehicle has been maintained and operated in accordance with the instructions for proper maintenance and use set forth in the Owner Manual and the Warranty and Maintenance Schedule booklets supplied with your vehicle. |
| • | The vehicle fails an EPA-approved I/M test during the emission warranty period. |
| • | The failure results, or will result, in the owner of the vehicle having to bear a penalty or other sanctions, including the denial of the right to use the vehicle, under local, state, or federal law. |
If all of these conditions are met, GM warrants that your dealer will replace, repair, or adjust to GM specifications, at no charge to you, any of the parts listed under the "Emission Warranty Parts List" later in this section, or parts thereof, which may be necessary to cause your vehicle to conform to the applicable emission standards. Non-GM parts labeled "Certified to EPA Standards" are also covered by this warranty.
