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

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-16405819) -
2023 - CRC - 3/22/22
Customer Information 467
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 resolved by your dealership
without further help, in the
U.S., call the Cadillac Customer
Assistance Center at
1-800–458–8006. In Canada,
call the Canadian Cadillac
Customer Care Centre at
1-888-446-2000.
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 Cadillac,
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
the 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 BBB National
Programs, Inc. 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:
