2012 Chevrolet Suburban 1500 RecallsIgnition Switch
The ignition switch actuator can bind causing the ignition switch to stick in the "start" position. If this were to occur the actuator can unexpectedly release, cause the ignition switch to snap back into the "Accessory" position. This would cause the engine to turn off with an associated loss of brake and steering power assist. If these conditions were to lead to a crash the airbags may not deploy as expected. Dealers will inspect and replace the ignition lock housing as necessary to correct this concern.
The steering gear pitman shaft may not have been adequately hardened and could break. If this occurs, a loss of steering ability will result, increasing the risk of a crash. Dealers will inspect the steering gear and replace the steering gear pitman shaft if necessary to correct this concern. The General Motors recall number is 12005.
