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, contact
the GMC Consumer Relations Manager by calling
1-800-GMC-8782 (1-800-462-8782, Customer
Assistance prompt). In Canada, contact GM
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 Identi cation 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.
