GENERAL MOTORS issued a recall on the SIERRA, and SILVERADO models

On certain vehicles, a defect in the ignition lock actuator may make turning the ignition key difficult or cause the key to get stuck in the “start” position. This may be more likely to occur at higher interior ambient temperatures. If the vehicle is driven with the key stuck in the “start” position, and the vehicle experiences a significant jarring event or the vehicle’s interior temperature cools, the ignition key could move out of the “start” position, rotate past the “run” position, and move into the “accessory” position, causing the engine to shut off. This would result in a loss of motive power and affect power steering and power brake system function, which could increase 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 in a crash event, may also result in the airbags not deploying in a subsequent collision, increasing the risk of injury. Correction: Dealers will replace the ignition lock housing.
