bulletin before customers take possession of these vehicles.
Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the

Dear General Motors Customer:
We have learned that your 2007, 2008, or 2009 model year Chevrolet Silverado or GMC Sierra, currently or previously registered in Connecticut,
Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey,
New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, and Wisconsin may have a condition where an electronic component located
beneath the driver's seat may corrode due to a significant quantity of snow and/or water containing road salt or other contaminants entering the vehicle
and saturating the acoustical padding beneath the carpet. Your vehicle's electronic sensing and diagnostic module (SDM) is located underneath this
acoustical padding. If sufficient moisture collects and is retained in the padding, it may cause excessive corrosion under the module; compromising the
module seal and allowing water intrusion and system malfunction. This may result in illumination of the Airbag Readiness light, along with a "Service
Airbag" message on the Driver Information Center, and in rare cases, deployment of the seat belt pretensioner and/or airbags.
Your satisfaction with your 2007, 2008, or 2009 model year Chevrolet Silverado or GMC Sierra is very important to us, so we are announcing a program
to prevent this condition.
What We Will Do: Your GM dealer will remove the acoustical padding above the SDM. This service will be performed for you at no charge.
What You Should Do: To limit any possible inconvenience, we recommend that you contact your dealer as soon as possible to schedule an appointment
for this repair.
