paint or appearance concerns,
advise your dealer as soon as
possible. Your owner manual has
instructions regarding the care of
these items.
Vehicle Operation and Care
Considering the investment you
have made in your Buick, we know
you will want to operate and
maintain it properly. We urge you to
follow the maintenance instructions
in your owner manual.
If you have questions on how to
keep your vehicle in good working
condition, see your Buick dealer, the
place many customers choose to
have their maintenance work done.
You can rely on your Buick dealer to
use the proper parts and repair
practices.
Maintenance and Warranty
Service Records
Retain receipts covering
performance of regular
maintenance. Receipts can be very
important if a question arises as towhether a malfunction is caused by
lack of maintenance or a defect in
material or workmanship.
A
“Maintenance Record” is provided
in the maintenance schedule
section of the owner manual for
recording services performed.
The servicing dealer can provide a
copy of any warranty repairs for
your records.
Chemical Paint Spotting
Some weather and atmospheric
conditions can create a chemical
fallout. Airborne pollutants can fall
upon and adhere to painted
surfaces on your vehicle. This
damage can take two forms:
blotchy, ring-shaped discolorations,
and/or small irregular dark spots
etched into the paint surface.
Although no defect in the factory
applied paint causes this, Buick will
repair, at no charge to the owner,
the painted surfaces of new vehicles
damaged by this fallout condition
within 12 months or 12,000 miles of
purchase, whichever comes first.
Warranty Coverage –
Extensions
Time Extensions : The New
Vehicle Limited Warranty will be
extended one day for each day
beyond the first 24 hour period in
which your vehicle is at an
authorized dealer facility for
warranty service. You may be asked
to show the repair orders to verify
the period of time the warranty is to
be extended. Your extension rights
may vary depending on state law.
Mileage Extensions : Prior to
delivery, some mileage is put on
your vehicle during testing at the
assembly plant, during shipping,
and while at the dealer facility. The
dealer records this mileage on the
first page of this warranty booklet at
delivery. For eligible vehicles, this
mileage will be added to the
mileage limits of the warranty
ensuring that you receive full benefit
of the coverage. Mileage extension
eligibility:
. Applies only to new vehicles

The California Air Resources Board
and General Motors are pleased to
explain the emission control system
warranty on your vehicle. In
California, new motor vehicles must
be designed, built, and equipped to
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.

specifications any genuine GM parts
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

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.

Buick Limited Warranty and Owner Assistance Information (GMNA-Localiz-
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
