GMC Yukon XL 1500 Problems4WD Transfer Case Position Sensor/Selector Switch May Fail
The 4WD transfer case encoder motor position sensor or the selector switch may fail causing the service 4WD message to be displayed. Fault code(s) stored in the transfer case control module will be of assistance in determining the exact fault causing the message to be displayed.
The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.
One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.

GMC Yukon XL 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 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.
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.
