2005 Pontiac Grand Am

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.

Certain vehicles were built with rear suspension knuckle bolts that are not to specification and could fracture under high loads that can occur in some driving conditions.  If the bolt fractures, the rear suspension linkage could detach from the knuckle and the rear wheel would be able to turn inboard or outboard.  Sudden changes could occur in vehicle handling and, particularly at higher speeds, the driver may not be able to control the vehicle and a crash could occur without warning.  Correction:  Dealers will replace both rear suspension knuckle bolts.
