2012 Chevrolet Silverado 2500 HD 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.
Vehicles equipped with a 6.6L diesel engine and dual fuel tanks are being recalled because the transfer pump that moves fuel from the rear tank to the front tank could cause the fuel gauge in show the incorrect fuel level. The engine could stall unexpectedly, increasing the risk of a crash. Dealers will inspect the fuel transfer pump and replace it as necessary to correct this concern.
