Customer Assistance and
Information
Customer Satisfaction Procedure
Your satisfaction and goodwill are important to
your dealer and to Chevrolet. 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, in the
U.S., contact the Chevrolet Customer Assistance
Center by calling 1-800-222-1020. In Canada, contact
General Motors of Canada Customer Communication
Centre 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 Identication 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
(kilometers).
When contacting Chevrolet, 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 — U.S. Owners:Both General Motors
and your dealer are committed to making sure you
are completely satised with your new vehicle. However,
if you continue to remain unsatised after following
the procedure outlined in Steps One and Two,
you should le 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.
