13-8 Customer Information
Courtesy Transportation
Program
To enhance your ownership
experience, we and our participating
dealers are proud to offer Courtesy
Transportation, a customer support
program for vehicles with the
Bumper-to-Bumper (Base Warranty
Coverage period in Canada),
extended powertrain, and/or
warranties specific to e-Assist in
both the U.S. and Canada.
Several Courtesy Transportation
options are available to assist in
reducing inconvenience when
warranty repairs are required.
Courtesy Transportation is not a
part of the New Vehicle Limited
Warranty. A separate booklet
entitled“Warranty and Owner
Assistance Information” furnished
with each new vehicle provides
detailed warranty coverage
information.
Transportation Options
Warranty service can generally be
completed while you wait. However,
if you are unable to wait, GM helps
to minimize inconvenience by
providing several transportation
options. Depending on the
circumstances, your dealer can
offer one of the following:
Shuttle Service
Shuttle service is the preferred
means of offering Courtesy
Transportation. Dealers may provide
shuttle service to get you to your
destination with minimal interruption
of your daily schedule. This includes
one‐way or round‐trip shuttle service
within reasonable time and distance
parameters of your dealer's area.
Public Transportation or Fuel
Reimbursement
If the vehicle requires overnight
warranty repairs, and public
transportation is used instead of
your dealer's shuttle service, the
expense must be supported by original receipts and can only
be up to the maximum amount
allowed by GM for shuttle service.
In addition, for U.S. customers,
should you arrange transportation
through a friend or relative, limited
reimbursement for reasonable fuel
expenses may be available. Claim
amounts should reflect actual
costs and be supported by original
receipts. See your dealer for
information regarding the allowance
amounts for reimbursement of fuel
or other transportation costs.
Courtesy Rental Vehicle
Your dealer may arrange to provide
you with a courtesy rental vehicle or
reimburse you for a rental vehicle
that you obtain if the vehicle is kept
for an overnight warranty repair.
Rental reimbursement will be limited
and must be supported by original
receipts. This requires that you sign
and complete a rental agreement
and meet state/provincial, local, and
rental vehicle provider requirements.
