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 system 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

Buick Limited Warranty and Owner Assistance Information (GMNA-Localiz-
ing-U.S-12032535) - 2019 - crc - 6/25/18
24 Emission Warranty Parts List
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 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 available
within 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
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 026.

26 Customer Satisfaction Procedure
Your satisfaction and goodwill are
important to your dealer and to
Buick. Normally, any concerns with
the sales transaction or the
operation of your vehicle will be
resolved by your dealer's sales or
service departments. Sometimes,
however, despite the best intentions
of all concerned, misunderstandings
can occur. If your concern has not
been resolved to your satisfaction,
the following steps should be taken:
STEP ONE : Discuss your
concern with a member of dealer
management.Normally, concerns
can be quickly resolved at that level.
If the matter has already been
reviewed with the sales, service,
or parts manager, contact the
owner of the dealer facility or the
general manager.
STEP TWO : If after contacting a
member of dealer management, it
appears your concern cannot be
resolved by the dealer without
further help contact the Buick
Customer Assistance Center by
calling 1-800-521-7300. In Canada, contact GM of Canada Care Centre
Office by calling 1-800-263-3777:
English, or 1-800-263-7854: French.
We encourage you to call the
toll-free number in order to give
your inquiry prompt attention.
Have the following information
available to give the Customer
Assistance Representative:
.
The Vehicle Identification
Number (VIN). This is available
from the vehicle registration or
title, or the plate above the top of
the instrument panel on the
driver side, and visible through
the windshield.
. The dealer name and location
. The vehicle delivery date and
present mileage
When contacting Buick, remember
that your concern will likely be
resolved at a dealer's facility. That is
why we suggest you follow
Step One first if you have a
concern. STEP THREE :
Both GM and your
Buick dealer are committed to
making sure you are completely
satisfied with your new vehicle.
However, if you continue to remain
unsatisfied after following the
procedure outlined in Steps One
and Two, you can file with the Better
Business Bureau (BBB) Auto Line
Program to enforce any additional
rights you may have.
The BBB Auto Line Program is an
out of court program administered
by the Council of Better Business
Bureaus to settle automotive
disputes regarding vehicle repairs or
the interpretation of the New Vehicle
Limited Warranty. Although you may
be required to resort to this informal
dispute resolution program prior to
filing a court action, use of the
program is free of charge and your
case will generally be heard within
40 days. If you do not agree with
the decision given in your case, you
may reject it and proceed with any
other venue for relief available
to you.
