not much help but I have a thought-- Did you check to make sure all the fuses are good? the shift is electronic.
do the brakes work? (won't shift unless brakes work)
check to see the tow procedures for this model... tow company could of manually put in it neutral and it needs to be reset. The old fashion manual shifters had a spot next to the shifter to manually set into tow mode. not sure about the fancy electronic shifter in mkc
