Information
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 GM 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
dealership 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 dealership or the
general manager.STEP TWO:If after contacting a member of dealership
management, it appears your concern cannot be
resolved by the dealership without further help, in the
U.S., contact the Buick Customer Assistance Center by
calling 1-800-521-7300. In Canada, contact General
Motors of Canada Customer Communication Centre 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. Please have
the following information available to give the Customer
Assistance Representative:
Vehicle Identication Number. This is available from
the vehicle registration or title, or the plate at the
top left of the instrument panel.
Dealership name and location
Vehicle delivery date and present mileage
When contacting Buick, please remember that your
concern will likely be resolved at a dealer’s facility. That
is why we suggest you follow Step One rst if you
have a concern.

STEP THREE — Canadian Owners:In the event that
you do not feel your concerns have been addressed after
following the procedure outlined in Steps one and two,
General Motors of Canada Limited wants you to be aware
of its participation in a no-charge Mediation/Arbitration
program. General Motors of Canada Limited has
committed to binding arbitration of owner disputes
involving factory-related vehicle service claims. The
program provides for the review of the facts involved by
an impartial third party arbiter, and may include an
informal hearing before the arbiter. The program is
designed so that the entire dispute settlement process,
from the time you le your complaint to the nal decision,
should be completed in approximately 70 days. We
believe our impartial program offers advantages over
courts in most jurisdictions because it is informal, quick,
and free of charge.For further information concerning eligibility in the
Canadian Motor Vehicle Arbitration Plan (CAMVAP), call
toll-free 1-800-207-0685. Alternatively you may call the
General Motors Customer Communication Centre,
