How to Determine the
Applicable Emissions Control
System Warranty
State and Federal agencies may
require a 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.

replace, repair, or adjust to GM
specifications, at no charge to you,
any of the parts listed under the

meet the state's stringent anti-smog
standards. GM must warrant the
emission control system on your
vehicle for the periods of time and
mileage listed provided there has
been no abuse, neglect, or improper
maintenance of your vehicle. Your vehicle's emission control system
may include parts such as the fuel
injection system, ignition system,
catalytic converter, and engine
computer. Also included are hoses,
belts, connectors, and other
emission-related assemblies.
Where a warrantable condition
exists, GM will repair your vehicle at
no cost to you including diagnosis,
parts, and labor.

that affect emissions. The applicable warranty period shall
begin on the date the vehicle is
delivered to the first retail purchaser
or, if the vehicle is first placed in
service as a demonstrator or
company vehicle prior to sale at
retail, on the date the vehicle is
placed in such service.
Owner's Warranty Responsibilities
As the vehicle owner, you are
responsible for the performance of
the scheduled maintenance listed in
your owner manual. GM
recommends that you retain all
maintenance receipts for your
vehicle, but GM cannot deny
warranty coverage solely for the
lack of receipts or for your failure to
ensure the performance of all
scheduled maintenance.
You are responsible for presenting
your vehicle to a Buick dealer
selling your vehicle line as soon as
a problem exists. The warranted
repairs should be completed in a
reasonable amount of time, not to
exceed 30 days.
As the vehicle owner, you should
also be aware that Buick may deny
warranty coverage if your vehicle or
a part has failed due to abuse,
neglect, improper or insufficient
maintenance, modifications not
approved by Buick, or if the defect
is not emissions-related.
If you have any questions regarding
your rights and responsibilities
under these warranties, you should
contact the Customer Assistance
Center at 1-800-222-1020 or, in
California, write to:

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
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.

ing-U.S.-10999171) - 2018 - crc - 7/31/17
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

Buick Limited Warranty and Owner Assistance Information (GMNA-Localiz-
ing-U.S.-10999171) - 2018 - crc - 7/31/17
Emission Warranty Parts List 25
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
theCustomer Satisfaction
Procedure 026.
