The ignition key cylinder may bind, resulting in the key sticking in the "start" position inadvertently. This can result in the key snapping back unexpectedly into the "accessory" position, and cause vehicle stalling and loss of safety features. Dealers will replace the ignition lock housing free of charge to resolve the concern.

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 chassis electrical module can short due to internal contamination. This can result in the vehicle stalling. Dealers will replace the chassis electronic module free of charge to resolve the concern.
For vehicles modified by Monroe Truck Equipment, the electrical converter and battery equalizer may overheat, causing a fire hazard. The components will be replaced by the manufacturer free of charge to resolve the concern.
All late model vehicles are equipped with a "Shift interlock" system that prevents vehicles with and automatic transmission from being shifted out of the Park position under certain conditions. Some of these vehicles are being recalled because they may have been assembled with a broken park lock cable or a malformed steering column lock actuator gear. Failure of these components can allow the shifter to be moved out of the Park position with the ignition key removed or in the off position. This can cause the vehicle to roll away unexpectedly increasing the risk of injury or a crash. Dealers will inspect the recalled vehicles and replace the steering column as necessary.
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.
The rear axle cross pin may break. The cross pin is an internal component of the rear differential, which is housed in the rear axle assembly. If the cross pin breaks, the rear axle may lock, which could result in loss of control and a crash. Dealers will install a new rear axle cross pin to correct this concern. This recall should begin no later than January 25, 2011. The General Motors number for this recall is 10426A.
The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.
The RTV seal on the fuel system control modules may allow water to enter into the module. Water in the module can cause a short, which may cause hard starting, a crank-no start condition, or stalling, and the Service Engine Soon light may come on. If the engine stalls unexpectedly, there is an increased risk of a crash. Dealers will replace the fuel system control module free of charge. The recall began on May 18, 2009. The GM recall number is 08411.
The wiring to the washer system heater may overheat due to a failure in the heater module. This could cause other electrical features to malfunction, smoke to develop, and an electrical fire could result. Dealers will install a wire harness with an inline fuse to protect the washer heater module. This recall is expected to begin on September 12, 2008. The General Motors recall number is 08048.
