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 chassis owner.
In an emergency, where an authorized dealer is
not reasonably available, repairs can be performed
at any available service establishment or by the
owner, using any replacement part. GM 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 GM'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 GM dealer
and you believe the repairs are covered by
emission warranties, take the replaced parts and
your receipt to a GM 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.
