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 your 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 Centre in Oshawa 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 (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.
STEP THREE:Both General Motors and your dealer
are committed to making sure you are completely
satis ed with your new vehicle. However, if you continue
to remain unsatis ed after following the procedure
outlined in Steps One and Two, you should le with the
BBB Auto Line Program to enforce any additional
rights you may have. Canadian owners refer to your
Warranty and Owner Assistance Information booklet for
information on the Canadian Motor Vehicle Arbitration
Plan (CAMVAP).
