The hazard
On certain vehicles, a defect in the ignition lock cylinder could cause the key to stick in the "start" position if the vehicle interior temperature is sufficiently high. If the vehicle is operated in this condition and the interior temperature cools or the vehicle goes off-road or is subjected to some other jarring event, the key could move out of the "start" position, rotate past the "run" position and into the "accessory" position. 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: Dealers will inspect the steering column for identifying information and replace if necessary.
