The 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. Correction Dealers are to remove the acoustical pad above the SDM.

For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided to dealers through the GM GlobalConnect Recall Reports. Dealers will not have a report available if they have no involved vehicles currently assigned. The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program. Parts Information No parts are required for this program. Service Procedure Note: Driver seat removal is NOT required for crew cab or extended cab vehicles. Certain 2009 regular cab vehicles built after approximately March 1, 2009 with carpet that has a 2-sided cutout over the SDM, however, will require driver seat removal. Refer to Front Seat Replacement-Bucket in SI. After the seat removal, proceed to Step 2 in the bulletin. Regular cab vehicles with carpet that has a 3-sided cut over the SDM do NOT require seat removal. Move the driver's seat to the full forward or rearward position.

Using your hand, tear away and remove the acoustical pad that covers the SDM. Ensure that no acoustical pad remains over, or in contact with, the SDM.

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. Claim Information 1. Submit a claim using the table below. 2. Courtesy Transportation - For dealers using WINS, submit using normal labor code; for dealers using GWM - submit as Net Item under the repair labor code.

Dealer Program Responsibility All unsold new vehicles in dealers' possession and subject to this program must be held and inspected/repaired per the service procedure of this program 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 forward. Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin.
