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).
