2007–2009 Gmc Sierra Recall

On certain vehicles located in Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland & Labrador, the Sensing and Diagnostic Module (SDM) 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 floor carpet. 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 certain instances, may cause inadvertent deployment of the seatbelt pretensioner and/or airbags. Inadvertent deployment of the driver and / or passenger front airbag in a non-accident (non-impact) situation may cause damage to the surrounding vehicle environment (windshield / instrument panel), and create expensive vehicle repair, including replacement of the airbag module(s). In some instances, inadvertent deployment could cause minor injuries to vehicle occupants. Correction: Dealers will remove the acoustic pad above the SDM.
