2011 GMC Yukon Recalls

Passenger Frontal Air Bag Inflator Ruptures On Deployment

The passenger frontal air bag inflator may rupture on deployment, causing metal fragments to come through the air bag and injure occupants. Dealers will replace the passenger frontal air bag inflator free of charge to resolve the concern.

Ignition 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.

Potential Loss of Steering Ability

The intermediate steering shaft attaching bolts may not have been tightened to the proper specification. This could allow the steering shaft to separate. The driver could experience a loss of steering ability, increasing the risk of a crash. Dealers will inspect and ensure the intermediate steering shaft bolts are tightened to the proper specification. This recall is expected to begin on July 13, 2011. The General Motors recall number is 11191.
