DEPARTMENT PERSONNEL
General Motors has determined that a defect which relates to motor vehicle safety exists in some 1990 Buick Riviera and Reatta model vehicles. In the
event of an accident requiring deployment of the driver's side Supplemental Inflatable Restraint (SIR), the SIR Inflator Module, located in the steering
wheel assembly, could separate. If separation occurs, the air bag will not inflate as intended, and the driver will not be properly restrained. In addition,
separation of the SIR Inflator Module may result in hot combustion gases escaping into the occupant compartment, presenting the possibility that vehicle
occupants could receive burn injuries.
