Customer Assistance
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 Identification 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 first
if you
have a concern.
STEP THREE: Both General Motors and your dealer
are committed to making sure you are completely
satisfied with your new vehicle. However,
if you continue
to remain unsatisfied after following the procedure
outlined in Steps One and Two, you should file with the
GM/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).

charge and your case will generally be heard within
40 days.
If you do not agree with the decision given in

Courtesy Transportation
GMC has always exemplified quality and value in its
offering of motor vehicles. To enhance your ownership
experience, we and our participating dealers are
proud to offer Courtesy Transportation, a customer
support program for new vehicles.
The Courtesy Transportation program is offered to retail
purchase/lease customers in conjunction with the
Bumper-to-Bumper coverage provided by the New
Vehicle Limited Warranty. Several transportation options
are available when warranty repairs are required.
This will reduce your inconvenience during warranty
repairs.
Plan Ahead When Possible
When your vehicle requires warranty service, you
should contact your dealer and request an appointment.
By scheduling a service appointment and advising
your service consultant of your transportation needs,
your dealer can help minimize your inconvenience.
If your vehicle cannot be scheduled into the service
department immediately, keep driving it until it can be
scheduled for service, unless, of course, the problem is
safety-related. If it is, please call your dealership, let
them know this, and
ask for instructions.
If the dealer requests that you simply drop the vehicle
off for service, you are urged to do so as early in
the work day as possible to allow for the same day
repair.
Transportation Options
Warranty service can generally be completed while you
wait. However,
if you are unable to wait, GMC helps
minimize your inconvenience by providing several
transportation options. Depending on the circumstances,
your dealer can offer you one of the following:
Shuttle Service
Participating dealers can provide you with shuttle
service to get you to your destination with minimal
interruption of your daily schedule. This includes a one
way shuttle ride to a destination up to
10 miles from
the dealership.
