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 your dealership or the general
manager.
STEP TWO : If after contacting a
member of dealership management,
it appears your concern cannot be

Mexico-11349177) - 2018 - CRC - 10/17/17

resolved by your dealership without
further help, in the U.S., call
1-800-462-8782. In Canada, call
General Motors of Canada
Customer Care Centre at
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. Have the
following information available to
give the Customer Assistance
representative:
.Vehicle Identification
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, remember
that your concern will likely be
resolved at a dealer's facility. That is
why we suggest following Step One
first. STEP THREE
—U.S. Owners :
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
can file with the Better Business
Bureau (BBB) Auto Line Program to
enforce your rights.
The BBB Auto Line Program is an
out-of-court program administered
by the Council of Better Business
Bureaus to settle automotive
disputes regarding vehicle repairs or
the interpretation of the New Vehicle
Limited Warranty. Although you may
be required to resort to this informal
dispute resolution program prior to
filing a court action, use of the
program is free of charge and your
case will generally be heard within
40 days. If you do not agree with the
decision given in your case, you
may reject it and proceed with any
other venue for relief available
to you. You may contact the BBB Auto Line
Program using the toll-free
telephone number or write them at
the following address:

limitations and/or discontinue its
participation in this program.

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
Company wants you to be aware of
its participation in a no-charge
Mediation/Arbitration Program.
General Motors of Canada
Company 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 about 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),
