12 Things to Know About the New Vehicle Limited Warranty
Warranty Repairs–
Component Exchanges
In the interest of customer
satisfaction, GM may offer
exchange service on some vehicle
components. This service is
intended to reduce the amount of
time your vehicle is not available for
use due to repairs. Components
used in exchange are service
replacement parts that may be new,
remanufactured, or refurbished.
Remanufactured parts meet GM
approved service part requirements
and are made from previously used
components in a process that
involves disassembly, inspection,
cleaning, update of software and
replacement of parts as appropriate,
testing and reassembly.
Refurbished parts meet GM
approved service part requirements
and are previously used parts that
are inspected, cleaned, tested, and
repackaged.
All exchange components used
meet GM standards and are
warranted the same as new components. Examples of the types
of components that might be
serviced in this fashion include:
engine and transmission
assemblies, instrument cluster
assemblies, radios, compact disc
players, batteries, and powertrain
control modules.
Warranty Repairs
–Recycled
Materials
Environmental Protection Agency
(EPA) guidelines and GM support
the capture, purification, and reuse
of automotive air conditioning
refrigerant gases and engine
coolant. As a result, any repairs GM
may make to your vehicle may
involve the installation of purified
reclaimed refrigerant and coolant.
Tire Service
Any authorized Buick or tire dealer
for your brand of tires can assist you
with tire service. If, after contacting
one of these dealers, you need
further assistance or you have
questions, contact the Buick
Customer Assistance Center. The toll-free telephone numbers are
listed under
Customer Assistance
Offices 031.
After-Manufacture
“Rustproofing”
Your vehicle was designed and built
to resist corrosion. Application of
additional rust-inhibiting materials is
neither necessary nor required
under the Sheet Metal Coverage.
Buick makes no recommendations
concerning the usefulness or value
of such products.
Application of after-manufacture
rustproofing products may create an
environment which reduces the
corrosion resistance built into your
vehicle. Repairs to correct damage
caused by such applications are not
covered under your New Vehicle
Limited Warranty.
Paint, Trim, and Appearance
Items
Defects in paint, trim, upholstery,
or other appearance items are
normally corrected during new
vehicle preparation. If you find any

20 Emission Warranty Parts List
Emission-related defects in the
emission parts listed here are
covered under the Emission Control
System Warranty. The terms are
explained in theEmission Control
Systems Warranty 016 under
“Federal Emission Control System
Warranty” and the“California
Emission Control System Warranty.”
Important: Certain parts may be
covered beyond these warranties if
shown with asterisk(s) as follows:
. (*) 7 years/70,000 miles,
whichever comes first, California
Emission Control System
Warranty coverage.
. (**) 8 years/80,000 miles,
whichever comes first, Federal
Emission Control System
Warranty coverage for light duty
vehicles. (Also applies to
California certified light duty
vehicles.)
All listed parts 15 years/
150,000 miles, whichever comes
first, on California TZEV (NU6)
vehicles registered in a TZEV state
except Hybrid batteries and Hybrid A/C compressors, which are
covered for 10 years/150,000 miles,
whichever comes first.
