Owner Letter

October 2009

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.

If you have any questions or need any assistance, just contact your dealer or the appropriate Customer Assistance Center at the number listed below.





Courtesy Transportation: If your vehicle is within the New Vehicle Limited Warranty, your dealer may provide you with shuttle service or some other form of courtesy transportation while your vehicle is at the dealership for this repair. Please refer to your Owner's Manual and your dealer for details on Courtesy Transportation.

We sincerely regret any inconvenience or concern that this situation may cause you. We want you to know that we will do our best, throughout your ownership experience, to ensure that your GM vehicle provides you many miles of enjoyable driving.
