Customer Information
Customer Satisfaction
Procedure
Your satisfaction and goodwill are
important to your dealer and to
Buick. 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

why we suggest following Step One
first. STEP THREE

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

348 Customer Information
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,

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.
