Summary
In all of the affected vehicles, the AWD module was assembled with an incorrect transistor that controls the transition between AWD and 2WD. When this transistor fails the vehicle will remain in either AWD or 2WD and not transition between the drive states. This can cause the wrench light to illuminate in the instrument cluster.
