Buick’s Commitment
Buick is committed to ensuring
satisfaction with your new vehicle.
Your dealer also wants you to be
completely satisfied and invites you
to return for all your service needs,
both during and after the warranty
period.
Owner Assistance
The dealer is best equipped to
provide all your vehicle's service
needs. Should you ever encounter a
problem that is not resolved during
or after the limited warranty period,
talk to a member of dealer
management. Under certain
circumstances, GM and/or Buick
dealers may provide assistance
after the limited warranty period has
expired when the problem results
from a defect in material or workmanship. These instances will
be reviewed on a case-by-case
basis. If the issue has not been
resolved to your satisfaction, follow
the
Customer Satisfaction
Procedure 026.
We thank you for choosing Buick.
Buick’ s Participation in an
Alternative Dispute Resolution
Program
See Customer Satisfaction
Procedure 026 for information on
the voluntary, non-binding
Alternative Dispute Resolution
Program in which GM participates.
Warranty Service– United
States
The selling dealer has invested in
the proper tools, training, and parts
inventory to ensure that any necessary warranty repairs can be
made to your Buick vehicle. Buick
requests that the vehicle be
returned to the selling dealer for all
warranty repairs. If a situation or
event occurs where you are
significantly inconvenienced, an
authorized GM dealer can make the
warranty repairs. However, in the
event the dealer is not able to
perform the repair due to the special
tool and training requirements,
contact the
Customer Assistance
Offices 031. If you are unable to
return to the selling dealer, contact a
GM dealer in the United States for
warranty service.

Tire Coverage
The tires supplied with your vehicle
are covered by General Motors
against defects in material or
workmanship under the
bumper-to-bumper warranty
coverage. Wear-out is not
considered a defect, and it may
occur before the vehicle warranty
expires. In this case, the owner is
responsible to purchase
replacement tires, or seek coverage
solely from the tire manufacturer.
For vehicles within the
bumper-to-bumper warranty
coverage, defective tires will be
replaced on a prorated adjustment
basis according to the following
mileage-based schedule:2019 Buick Tire Pro-Rate Chart
Mileage (mi) Percent Covered byBuick (Tire Cost) Percent Covered by
Buick (Labor —
Mount/Balance)
0-12,000 100% 100%
12,001-15,000 60% 100%
15,001-20,000 50% 100%
20,001-25,000 40% 100%

30,001-50,000 20% 100%
50,000 + 0% 0%
This schedule applies to the price of
the tires only. Buick will cover 100%
of the cost to mount and balance
the tires replaced under warranty for
the full bumper-to-bumper warranty
period.
After your New Vehicle Limited
Warranty expires, you may still have
prorated warranty coverage on your
original equipment tires by the tire
manufacturer. Contact your Buick
dealer or the tire manufacturer of the brand of tires on your vehicle for
more information. The following is a
list of current tire manufacturer's
websites and toll-free customer
assistance numbers.
