2003 Chevrolet Malibu

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 vehicles, in hot ambient conditions, the accelerator pedal arm may stick at the attachment to the bracket and not return to the engine idle position when the operator removes the actuating force from the accelerator pedal.  If the accelerator pedal does not return to the engine idle position, the throttle valve will not close, which may result in an increased stopping distance.  Correction:  Dealers will inspect the accelerator pedal arm and, if necessary, replace the accelerator and brake pedal assembly.
