24 Emission Warranty Parts List
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 a situation where
the vehicle owner is significantly
inconvenienced and a warranted
part or a warranty station is not
reasonably available to the vehicle
owner.
In a situation where the vehicle
owner is significantly
inconvenienced, and an authorized
dealer is not reasonably available,
repairs may be performed at any
available service establishment or
by the owner, using any
replacement part. Buick 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 Buick's recommended time
allowance for the warranty repair
and the geographically appropriate
labor rate. A part not being availablewithin 10 days or a repair not being
completed within 30 days
constitutes a significant
inconvenience. Retain receipts and
failed parts in order to receive
compensation for warranty repairs
reimbursable due to these
situations.
If you are in a situation where you
are significantly inconvenienced and
it is necessary to have repairs
performed by other than a Buick
dealer and you believe the repairs
are covered by emission warranties,
take the replaced parts and your
receipt to a Buick 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 other repairs (such as those
outlined earlier) 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 Buick
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
Buick 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
