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, contact the GM Medium Duty Truck Customer
Assistance Center at 1-800-862-4389. 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 (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 first if you have a concern.
