On certain vehicles, a defect in the ignition switch could allow the switch to move out of the "run" position if the key ring is carrying added weight or the vehicle goes off-road or is subjected to some other jarring event. If this were to occur, engine power, power steering and power braking would be affected, increasing the risk of a crash causing injury and/or damage to property. The timing of the key movement out of the “run” position, relative to the activation of the sensing algorithm of the crash event, may also result in the airbags not deploying in a subsequent collision, increasing the risk of injury. Correction: For each key, dealers will install two key rings and modify the key ring opening shape. Note: Until the correction is performed, all items should be removed from the key ring.
On certain Aurora, Bonneville SSEi, Devile and STS vehicles, the fuel tank pressure sensor is unusually susceptible to malfunctions causing excessive vacuum to be applied during self-diagnostic testing. Fuel system components can be damaged and fuel can leak from the vehicle when it is refueled. Possible symptoms of this condition are illumination of the Service Engine Soon light, poor driveability, increase noise from the fuel tank area, and inaccurate fuel gauge readings. If there is an ignition source present, a fire could result. Correction: Dealer will replace the fuel tank pressure sensor.
On certain vehicles, the driver's side air bag may not deploy as designed, resulting in reduced capability of the air bag to protect the driver. In addition, the air bag inflator may fracture. If this were to occur, pieces of the inflator could strike and injure the vehicle occupants. Correction: Dealer will inspect, and if necessary, install a new driver's air bag.
Certain vehicles may have a driver's side airbag inflator that could fracture at a weld during a deployment. Pieces of the inflator could strike and injure vehicle occupants and the airbag cushion would not inflate fully, reducing the capacity of the bag to protect the driver. Correction: Dealers are to inspect and if necessary replace the driver side airbag module assembly.
