Courtesy Transportation
Buick has always exemplied quality and value in its
offering of motor vehicles. To enhance your ownership
experience, we and our participating dealers 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 your vehicle cannot be scheduled into the service
department immediately, keep driving it until it can be
scheduled for service, unless, of course, the problem
is safety-related. If it is, please call your dealership,
let them know this, and ask for instructions.
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.
