Dear General Motors Customer:
This notice is sent to inform you that General Motors is conducting a voluntary emission recall
that includes your vehicle.
Reason For This Recall: General Motors has decided to conduct a Voluntary Emission
Recall involving certain 2010 model year Chevrolet Express, Silverado HD; and GMC Savana,
Sierra HD vehicles equipped with a 6.6L V8 Duramax diesel engine; and 2007-2009 model
year Chevrolet Express, Kodiak, Silverado HD; and GMC Savana, Sierra HD, and TopKick
vehicles equipped with a 6.6L V8 Duramax diesel engine that may have been serviced with a
suspect Exhaust Gas Temperature (EGT) sensor. The circuit board welds on the EGT
sensors in the exhaust system may not be to GM specification. If a weld fails, the Service
Engine Soon light will illuminate in the instrument panel, the exhaust gas may not be filtered
properly, and the engine power may be reduced.
What Will Be Done: Your GM dealer will replace both EGT sensors. This service will be
performed for you at no charge.
What You Should Do: Please contact your GM dealer as soon as possible to arrange a
service date and to assure parts availability. Instructions for making this correction have been
sent to your dealer. Please ask your dealer if you wish to know how much time will be
needed to schedule, process, and repair your vehicle.
If you have any questions or need any assistance, just contact your dealer or the appropriate
Customer Assistance Center at the number listed below.

Emission Law Information: In order to ensure your full protection under the emission
warranty made applicable to your vehicle by State and Federal Law, and your right to
participate in future recalls, it is recommended that you have your vehicle serviced as soon as
possible. Failure to do so could legally be determined to be lack of proper maintenance of
your vehicle. Also, your vehicle may fail a state or local emission inspection if this recall is
not accomplished.

IMPORTANT MESSAGE FOR CALIFORNIA RESIDENTS
The California Air Resources Board (CARB) requires vehicle emission recalls be completed
prior to California registration renewal. Uncorrected emission recalls will result in the inability
to renew your California vehicle registration.
At the time of emission recall completion, your California dealer will issue a "Proof of
Correction Certificate". Keep this certificate and, if required, present it to the Department of
Motor Vehicles when renewing your California registration as proof of recall completion.
We are sorry to cause you this inconvenience; however, we have taken this action in the
interest of your continued satisfaction with our products.
