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.
