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

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.

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.

that your concern will likely be resolved at a
dealer’s facility. That is why we suggest you
