13-18 Customer Information
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
This GM vehicle has a number of
sophisticated computers that record
information about the vehicle’s
performance and how it is driven.
For example, the vehicle uses
computer modules to monitor and
control engine and transmission
performance, to monitor the
conditions for airbag deployment
and deploy airbags in a crash, and,
if so equipped, to provide antilock
braking to help the driver control the
vehicle. These modules may store
data to help your dealer technician
service the vehicle. Some modules
may also store data about how you
operate the vehicle, such as rate of
fuel consumption or average speed.
These modules may also retain the
owner’s personal preferences, such
as radio presets, seat positions, and
temperature settings.
