customer satisfaction. Dealers are to ensure that these customers understand that shuttle service

CUSTOMER NOTIFICATION
General Motors will notify customers of this special coverage on their vehicles (see copy of typical
customer letter included with this bulletin - actual divisional letter may vary slightly).

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of
conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicl e. Properly trained
technicians have the tools, equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO
NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your dealer/retailer for information on
whether your vehicle may benefit from the information.

Dear General Motors Customer:
As the owner of a 2009-2010 model year Chevrolet Colorado or GMC Canyon, your satisfaction
with our product is very important to us.
This letter is intended to make you aware that on some 2009 and 2010 Chevrolet Colorado and
GMC Canyon vehicles, equipped with a 2.9L engine, high exhaust temperatures may cause the
exhaust manifold to fracture. This could result in increased exhaust noise.
Do not take your vehicle to your GM dealer as a result of this letter unless you believe that
your vehicle has the condition as described above.
What We Have Done: General Motors is providing owners with additional protection for the
condition described above. If this condition occurs on your 2009-2010 model year Chevrolet
Colorado or GMC Canyon within 10 years of the date your vehicle was originally placed in service
or 120,000 miles (193,000 km), whichever occurs first, the condition will be repaired for you at no
charge. Diagnosis or repair for conditions other than the condition described above is not
covered under this special coverage program.
What You Should Do: If you believe that your vehicle has the condition described above, repairs
and adjustments qualifying under this special coverage must be performed by a General Motors
dealer. You may want to contact your GM dealer to find out how long they will need to have your
vehicle so that you may schedule the appointment at a time that is convenient for you. This will
also allow your dealer to order parts if they are not already in stock. Keep this letter with your
other important glove box literature for future reference.
Reimbursement: If you have paid for repairs for the condition described in this letter, please
complete the enclosed reimbursement form and present it to your dealer with all required
documents. Working with your dealer will expedite your request, however, if this is not
convenient, you may mail the completed reimbursement form and all required documents to
