Customer Satisfaction
Procedure (U.S. and
Canada)
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 your dealership or the general
manager.

STEP THREE—Canadian
Owners: In the event that you do
not feel your concerns have been
addressed after following the
procedure outlined in Steps One
and Two, General Motors of Canada
Limited wants you to be aware
of its participation in a no-charge
Mediation/Arbitration Program.
General Motors of Canada Limited
has committed to binding arbitration
of owner disputes involving
factory-related vehicle service
claims. The program provides for
the review of the facts involved by
an impartial third party arbiter, and
may include an informal hearing
before the arbiter. The program is
designed so that the entire dispute
settlement process, from the time
you file your complaint to the final
decision, should be completed in
approximately 70 days. We believe
our impartial program offers
advantages over courts in most
jurisdictions because it is informal,
quick, and free of charge. For further information concerning
eligibility in the Canadian Motor
Vehicle Arbitration Plan (CAMVAP),
call toll-free 1-800-207-0685, or call
the General Motors Customer Care
Centre, 1-800-263-3777 (English),
1-800-263-7854 (French),
