COURTESY TRANSPORTATION – For US and Canada
The General Motors Courtesy Transportation program is intended to minimize customer
inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited
Warranties. The availability of courtesy transportation to customers whose vehicles are within the
warranty coverage period and involved in a product program is very important in maintaining
customer satisfaction. Dealers are to ensure that these customers understand that shuttle
service or some other form of courtesy transportation is available and will be provided at no
charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for
Courtesy Transportation guidelines.

(for customers who had CSP 10287 performed)
Dear General Motors Customer:
As the owner of a 2007 model year GMC Acadia or Saturn OUTLOOK; 2007-2009 model year
Cadillac CTS, SRX, or STS; 2009 model year Buick Enclave, Chevrolet Traverse, GMC Acadia,
or Saturn OUTLOOK, your satisfaction with our product is very important to us.
Recently, you took your vehicle to your dealer to have Customer Satisfaction Program 10287
performed. Your dealer reprogrammed the engine control module to prevent premature wear of
the timing chain and the illumination of the Service Engine Soon light. Further analysis has
shown that the reprogramming may not fully correct this condition for all vehicles; we, therefore,
are providing you with additional protection for the timing chain.
What We Have Done: General Motors is providing owners with additional protection for the
timing chain. If premature wear of the timing chain occurs on your 2007 model year GMC Acadia
or Saturn OUTLOOK; 2007-2009 model year Cadillac CTS, SRX, or STS; 2009 model year Buick
Enclave, Chevrolet Traverse, GMC Acadia, or Saturn OUTLOOK vehicle, equipped with a
2.8L/3.6L V6 engine, 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.
Do not take your vehicle to your GM dealer as a result of this letter unless you believe that
the Service Soon Engine light has illuminated due to timing chain wear.
What You Should Do: If you believe that your vehicle's Service Engine Soon light has
illuminated due to timing chain wear, 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 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 form and all required documents to Reimbursement Department, PO Box 33170,
Detroit, MI 48232-5170. The completed form and required documents must be presented to your
dealer or received by the Reimbursement Department by July 31, 2013, unless state law specifies
a longer reimbursement period.
If you have any questions or need any assistance, just contact your dealer or the appropriate
Customer Assistance Center at the number listed below.

(for customers who did not have CSP 10287 performed)
Dear General Motors Customer:
As the owner of a 2007 model year GMC Acadia or Saturn OUTLOOK; 2007-2009 model year
Cadillac CTS, SRX, or STS; 2009 model year Buick Enclave, Chevrolet Traverse, GMC Acadia,
or Saturn OUTLOOK, your satisfaction with our product is very important to us.
Your vehicle was designed and built to meet GM's high standards for quality and reliability.
However, we have determined that under certain driving conditions, and with your vehicle's
original oil change intervals, the timing chain could wear prematurely and cause the illumination of
the Service Engine Soon Light. Timing chain wear can be affected by the age of the engine oil
and driving conditions.
In April of this year, we sent you a letter informing you of a Customer Satisfaction Program to
correct this condition. That program was available until October 31, 2012, and has now expired.
However, General Motors is providing owners with additional protection for the timing chain. If
premature wear of the timing chain occurs on your 2007 model year GMC Acadia or Saturn
OUTLOOK; 2007-2009 model year Cadillac CTS, SRX, or STS; 2009 model year Buick Enclave,
Chevrolet Traverse, GMC Acadia, or Saturn OUTLOOK vehicle, equipped with a 2.8L/3.6L V6
engine, equipped with a V6 engine, within 10 years of the date your vehicle was originally placed
in service or 120,000 miles, 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.
Do not take your vehicle to your GM dealer as a result of this letter unless you believe that
the Service Soon Engine light has illuminated due to timing chain wear.
What You Should Do: If you believe that your vehicle's Service Engine Soon light has
illuminated due to timing chain wear, repairs and adjustments qualifying under this special
coverage must be performed by a GM dealer. You may want to contact your 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 and have
not submitted for reimbursement, please complete the enclosed 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 form and all required documents to
Reimbursement Department, PO Box 33170, Detroit, MI 48232-5170. The completed form and
required documents must be presented to your dealer or received by the Reimbursement
Department by November 30, 2013, unless state law specifies a longer reimbursement period.
If you have any questions or concerns that your dealer is unable to resolve, please contact the
appropriate Customer Assistance Center at the number listed below.
