Customer Assistance and
Information
Customer Satisfaction Procedure
Your satisfaction and goodwill are important
to your dealer and to GMC. Normally, any
concerns with the sales transaction or the
operation of the vehicle will be resolved by your
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 GMC
Consumer Relations Manager by calling
1-800-GMC-8782 (1-800-462-8782, Customer
Assistance prompt). In Canada, contact General
Motors of Canada Customer Communication
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 (VIN). This is
available from the vehicle registration or
title, or the plate at the top left of the
instrument panel and visible through the
windshield.
Dealership name and location.
Vehicle delivery date and present mileage.
When contacting GMC, 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.
