The official notice
Defect
Certain vehicles, after being exposed to substantial amounts of water, may experience deployment of either the driver or passenger front airbag without a crash. The owner’s manual for these vehicles does not provide specific information about this situation. 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) and the Sensing and Diagnostic Module (SDM). In some instances, inadvertent deployment could cause minor injuries to vehicle occupants.
Safety Risk
No risk description available.
Remedy
GM will notify the owners of these 1996 and 1997 vehicles of the potential affect of water accumulating in the vehicle interior on the function of the airbag system (as included in the owner's manuals of 1998 and later model years vehicles).
