Supercede:
This bulletin has been revised to include an inspection procedure and a new labor code. Vehicles with vinyl flooring and no cutout flap require no repair. All technicians are to review the new inspection procedure immediately. Please discard all copies of bulletin 09184, issued October 2009.
Condition
Certain 2007-2009 model year Chevrolet Silverado and GMC Sierra vehicles 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. 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.
Vehicles Involved
Involved are certain 2007-2009 model year Chevrolet Silverado and GMC Sierra vehicles 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, and built within these VIN breakpoints:
Important
Dealers are to confirm vehicle eligibility prior to beginning repairs by using GMVIS (dealers using WINS) or the Investigate Vehicle History screen (dealers using GWM). Not all vehicles within the above breakpoints may be involved.
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
1. If the vehicle is equipped with vinyl flooring and no cutout flap under the driver's seat, no further action is required. For all other vehicles, proceed to Step 2.
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.
2. Move the driver's seat to the full forward or rearward position.

4. Using your hand, tear away and remove the acoustical pad (3) that covers the SDM (4). Ensure that no acoustical pad remains over, or in contact with, the SDM (4).
5. Lower the carpet or vinyl cutout flap over SDM (4) and adjust the driver's seat to the customer-desired position.
Courtesy Transportation
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.
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.
Customer Notification
General Motors will notify customers of this program on their vehicle (see copy of customer letter included with this bulletin).
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. A copy of the customer letter is shown in this bulletin for your use in contacting customers. Program follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this program enters your vehicle inventory, or is in your dealership for service in the future, you must take the steps necessary to be sure the program correction has been made before selling or releasing the vehicle.
