GMC Yukon Problems

ABS Front Wheel Speed Sensors May Fail

The anti-lock brake system (ABS) front wheel speed sensors are prone to failure. When a sensor fails, the ABS warning light may illuminate and/or the ABS system may activate erratically.

The Upper Dash May Crack

The upper dash may crack, most commonly on vehicles in warm climates and exposed to a lot of sunlight. The common repair is to replace the upper instrument trim panel. Information on a technical service bulletin or extended warranty is not available at this time.

Power Door Lock Actuators May Fail

The power door lock actuators may become slow to operate or stop working completely and require replacement.

GMC Yukon Recalls

Front Suspension Control Arm Welds Fail

The front suspension upper control arms may have welds that are not sufficient, resulting in separation of the arm from the bushing. Dealers will replace both the left and right upper control arms and realign the vehicle suspension 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.

Loss of Power Steering Assist

A fault can develop with the Electric Power Steering resulting in sudden loss of power steering assist, increasing the risk of a crash. Dealers will replace the power steering assist motor kit to correct this concern.
