Customer Satisfaction ProcedureYour satisfaction and goodwill are important to your
dealer and to Buick. 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.

Courtesy Transportation
Buick has always exemplified quality and value in its
offering of motor vehicles. To enhance your ownership
experience, we and our participating dealerships are
proud to offer Courtesy Transportation, a customer
support program for new vehicles.
The Courtesy Transportation program is offered to retail
purchase/lease customers in conjunction with the
Bumper to Bumper coverage provided by the New
Vehicle Limited Warranty. Several transportation
options are available when warranty repairs are
required. This will reduce your inconvenience during
warranty repairs.
Plan Ahead When Possible
When your vehicle requires warranty service, you
should contact your dealer and request an appointment.
By scheduling a service appointment and advising your
service consultant of your transportation needs, your
dealer can help minimize your inconvenience. If it is
determined that your vehicle cannot be scheduled into
the service department immediately and is still
operative, you are encouraged to drive the vehicle until
scheduling can be accomplished.If the dealer requests that you simply drop the vehicle
off for service, you are urged to do so as early in the
work day as possible to allow for same day repair.
Transportation Options
Warranty service can generally be completed while you
wait. However, if you are unable to wait Buick helps
minimize your inconvenience by providing several
transportation options. Depending on the circumstances,
your dealer can offer you one of the following:
Shuttle Service
Participating dealerships can provide you with shuttle
service to get you to your destination with minimal
interruption of your daily schedule. This includes a one
way shuttle ride to a destination up to 10 miles from
the dealership.
Public Transportation or Fuel Reimbursement
If your vehicle requires overnight warranty repairs,
reimbursement up to $30 per day (five days maximum)
may be available for the use of public transportation such
as taxi or bus. In addition, should you arrange
transportation through a friend or relative, reimbursement
for reasonable fuel expenses up to $10 per day (five day
maximum) may be available. Claim amounts should
reflect actual costs and be supported by original receipts.

Courtesy Rental Vehicle
When your vehicle is unavailable due to overnight
warranty repairs, your dealer may arrange to provide you
with a courtesy rental vehicle or reimburse you for a rental
vehicle you obtained, at actual cost, up to a maximum of
$30.00 per day supported by receipts. This requires that
you sign and complete a rental agreement and meet state,
local and rental vehicle provider requirements.
Requirements vary and may include minimum age
requirements, insurance coverage, credit card, etc. You are
responsible for fuel usage charges and may also be
responsible for taxes, levies, usage fees, excessive mileage
or rental usage beyond the completion of the repair.
Generally it is not possible to provide a like
-vehicle as a
courtesy rental.
Additional Program Information
Courtesy Transportation is available during the
Bumper
-to-Bumper warranty coverage period, but it is not
part of the New Vehicle Limited Warranty. A separate
booklet entitled ªWarranty and Owner Assistance
Informationº furnished with each new vehicle provides
detailed warranty coverage information.
Courtesy Transportation is available only at
participating dealerships and all program options, such
as shuttle service, may not be available at every dealer.Please contact your dealer for specific information about
availability. All Courtesy Transportation arrangements
will be administered by appropriate dealer personnel.
Canadian Vehicles: For warranty repairs during the
Complete Vehicle Coverage period of the General
Motors of Canada New Vehicle Limited Warranty,
alternative transportation may be available under the
Courtesy Transportation Program. Please consult your
dealer for details.
General Motors reserves the right to unilaterally modify,
change or discontinue Courtesy Transportation at any
time and to resolve all questions of claim eligibility
pursuant to the terms and conditions described herein at
its sole discretion.
General Motors and participating dealerships reserve
the right to deny a rental vehicle to anyone not
possessing a valid motor vehicle operators license in
their name, anyone who is under the influence of alcohol
or drugs, or anyone whose mental or physical abilities
are impaired so as to be unable to operate a motor
vehicle safely.
Warranty Information
Your vehicle comes with a separate warranty booklet
that contains detailed warranty information.
