Courtesy Transportation
Chevrolet 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 Chevrolet 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.
