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 the same day
repair.
Transportation Options
Warranty service can generally be completed while you
wait. However, if you are unable to wait, GMC 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 dealers can provide you with shuttle
service to get you to your destination with minimal
interruption of your daily schedule. This includes a
one way or round trip 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 (ve 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 (ve day maximum) may
be available. Claim amounts should reect actual
costs and be supported by original receipts.
Courtesy Rental Vehicle
Your dealer may arrange to provide you with a
courtesy rental vehicle or reimburse you for a rental
vehicle you obrtained if your vehicle is kept for a
warranty repair. Reimbursement will be limited to a
maximum of $30.00 a day and must be 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.

Vehicle Data Collection and Event
Data Recorders
Your vehicle, like other modern motor vehicles, has a
number of sophisticated computer systems that monitor
and control several aspects of the vehicle’s performance.
Your vehicle uses on-board vehicle computers to monitor
emission control components to optimize fuel economy,
to monitor conditions for air bag deployment and, if so
equipped, to provide anti-lock braking and to help the
driver control the vehicle in difficult driving situations.
Some information may be stored during regular
operations to facilitate repair of detected malfunctions;
other information is stored only in a crash or near crash
event by computer systems commonly called event
data recorders (EDR).
In a crash or near crash event, computer systems, such
as the Air Bag Sensing and Diagnostic Module (SDM)
in your vehicle may record information about the
condition of the vehicle and how it was operated, such
as engine speed, brake applications, throttle position,
vehicle speed, safety belt usage, air bag readiness,
air bag performance data, and the severity of a collision.
This information has been used to improve vehicle
crash performance and may be used to improve crash
performance of future vehicles and driving safety.
Unlike the data recorders on many airplanes, these
on-board systems do not record sounds, such as
conversation of vehicle occupants.
