Parts specified in your maintenance schedule that require scheduled replacement are covered up to their first replacement interval or the applicable emission warranty coverage period, whichever comes first. If failure of one of these parts results in failure of another part, both will be covered under the Emission Control System Warranty.
For detailed information concerning specific parts covered by these emission control systems warranties, ask your dealer.
Replacement Parts
The emission control systems of your vehicle were designed, built, and tested using genuine GM parts* and the vehicle is certified as being in conformity with applicable federal and California emission requirements. Accordingly, it is recommended that any replacement parts used for maintenance or for the repair of emission control systems be new, genuine GM parts.
The warranty obligations are not dependent upon the use of any particular brand of replacement parts. The owner may elect to use non-genuine GM parts for replacement purposes. Use of replacement parts which are not of equivalent quality may impair the effectiveness of emission control systems.
If other than new, genuine GM parts are used for maintenance replacements or for the repair of parts affecting emission control, the owner should assure himself/herself that such parts are warranted by their manufacturer to be equivalent to genuine GM parts in performance and durability.
* "Genuine GM parts," when used in connection with GM vehicles means parts manufactured by or for GM, designed for use on GM vehicles, and distributed by any division or subsidiary of GM.
Maintenance and Repairs
Maintenance and repairs can be performed by any qualified service outlet; however, warranty repairs must be performed by an authorized dealer except in an emergency situation when a warranted part or a warranty station is not reasonably available to the vehicle owner.
In an emergency, where an authorized dealer is not reasonably available, repairs may be performed at any available service establishment or by the owner, using any replacement part. GMC will consider reimbursement for the expense incurred, including diagnosis, not to exceed the manufacturer's suggested retail price for all warranted parts replaced and labor charges based on GMC's recommended time allowance for the warranty repair and the geographically appropriate labor rate. A part not being available within 10 days or a repair not being completed within 30 days constitutes an emergency. Retain receipts and failed parts in order to receive compensation for warranty repairs reimbursable due to an emergency.
If, in an emergency situation, it is necessary to have repairs performed by other than a GMC dealer and you believe the repairs are covered by emission warranties, take the replaced parts and your receipt to a GMC dealer for reimbursement consideration. This applies to both the Federal Emission Defect Warranty and Federal Emission Performance Warranty.
Receipts and records covering the performance of regular maintenance or emergency repairs should be retained in the event questions arise concerning maintenance. These receipts and records should be transferred to each subsequent owner. GM will not deny warranty coverage solely on the absence of maintenance records. However, GM may deny a warranty claim if a failure to perform scheduled maintenance resulted in the failure of a warranty part.
Claims Procedure
As with the other warranties covered in this booklet, take your vehicle to any authorized GMC dealer facility to obtain service under the emission warranty. This should be done as soon as possible after failing an EPA-approved I/M test or a California smog check test, or at any time you suspect a defect in a part.
Those repairs qualifying under the warranty will be performed by any GMC dealer at no charge. Repairs which do not qualify will be charged to you. You will be notified as to whether or not the repair qualifies under the warranty within a reasonable time, not to exceed 30 days after receipt of the vehicle by the dealer, or within the time period required by local or state law.
The only exceptions would be if you request or agree to an extension, or if a delay results from events beyond the control of your dealer or GM. If you are not so notified, GM will provide any required repairs at no charge.
In the event a warranty matter is not handled to your satisfaction, refer to the "Customer Satisfaction Procedure" under Owner Assistance .
