Customer Satisfaction ProcedureYour 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.
