Managing the Vehicle
Damage Repair Process
In the event that the vehicle
requires damage repairs, GM
recommends that you take an
active role in its repair. If you
have a pre-determined repair
facility of choice, take the
vehicle there, or have it towed
there. Specify to the facility
that any required replacement
collision parts be original
equipment parts, either new
Genuine GM parts or recycled
original GM parts. Remember,
recycled parts will not be
covered by the GM vehicle
warranty.
Insurance pays the bill for the
repair, but you must live with
the repair. Depending on your
policy limits, your insurance
company may initially value the
repair using aftermarket parts.
Discuss this with the repair
professional, and insist on Genuine GM parts. Remember,
if the vehicle is leased, you
may be obligated to have the
vehicle repaired with Genuine
GM parts, even if your
insurance coverage does not
pay the full cost.
If another party's insurance
company is paying for the
repairs, you are not obligated
to accept a repair valuation
based on that insurance
company's collision policy
repair limits, as you have no
contractual limits with that
company. In such cases, you
can have control of the repair
and parts choices as long as
the cost stays within
reasonable limits.

Vehicle Data
Recording and
Privacy
The vehicle has a number of
computers that record
information about the vehicle’s
performance and how it is
driven or used. For example,the vehicle uses computer
modules to monitor and
control engine and
transmission performance, to
monitor the conditions for
airbag deployment and deploy
them in a crash, and,
if equipped, to provide antilock
braking to help the driver
control the vehicle. These
modules may store data to
help the dealer technician
service the vehicle or to help
GM improve safety or
features. Some modules may
also store data about how the
vehicle is operated, such as
rate of fuel consumption or
average speed. These
modules may retain personal
preferences, such as radio
presets, seat positions, and
temperature settings.
