Warranty

Emission Control Systems Warranty
The emission warranty on your vehicle is issued in
accordance with the U.S. Federal Clean Air Act. Defects
in material or workmanship in GM emission parts may
also be covered under the New Vehicle Limited Warranty
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 warranty are listed
under “Emission Warranty Parts List” later in this section.
How to Determine the Applicable
Emissions Control System Warranty
State and Federal agencies may require different
emission control system warranty depending on:
Whether the vehicle conforms to regulations
applicable to light duty or heavy duty emission
control systems.
Whether the vehicle conforms to or is certified for
California regulations in addition to U.S. EPA
Federal regulations.
All vehicles are eligible for Federal Emissions Control
System Warranty Coverage. If the emissions control
label contains language stating the vehicle conforms to
California regulations, the vehicle is also eligible for
California Emissions Control System Warranty Coverage.
