Cadillac 2012 SRX Owner's Manual page 484

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.
Service Manuals have the diagnosis
and repair information on the
engines, transmission, axle,
suspension, brakes, electrical,
steering, body, etc.
Service Bulletins give additional
technical service information
needed to knowledgeably service
General Motors cars and trucks.
Each bulletin contains instructions
to assist in the diagnosis and
service of the vehicle.
