Collision Damage Repair
If your vehicle is involved in a
collision and it is damaged, have the
damage repaired by a qualified
technician using the proper
equipment and quality replacement
parts. Poorly performed collision
repairs diminish your vehicle's
resale value, and safety
performance can be compromised
in subsequent collisions.
Collision Parts
Genuine GM Collision parts are new
parts made with the same materials
and construction methods as the
parts with which your vehicle was
originally built. Genuine GM
Collision parts are your best choice
to ensure that your vehicle's
designed appearance, durability,
and safety are preserved. The use
of Genuine GM parts can help
maintain your GM New Vehicle
Limited Warranty.
Recycled original equipment parts
may also be used for repair. These
parts are typically removed from
vehicles that were total losses in
prior crashes. In most cases, the
parts being recycled are from
undamaged sections of the vehicle.
A recycled original equipment GM
part may be an acceptable choice
to maintain your vehicle's originally
designed appearance and safety
performance; however, the history of
these parts is not known. Such parts
are not covered by your GM New
Vehicle Limited Warranty, and any
related failures are not covered by
that warranty.
Aftermarket collision parts are also
available. These are made by
companies other than GM and may
not have been tested for your
vehicle. As a result, these parts
may fit poorly, exhibit premature
durability/corrosion problems,
and may not perform properly in
subsequent collisions. Aftermarket
parts are not covered by your GM
New Vehicle Limited Warranty, and
any vehicle failure related to such
parts is not covered by that
warranty.
Repair Facility
GM also recommends that you
choose a collision repair facility that
meets your needs before you ever
need collision repairs. Your dealer
may have a collision repair center
with GM-trained technicians and
state
‐ of ‐ the ‐ art equipment, or be
able to recommend a collision repair
center that has GM-trained
technicians and comparable
equipment.
