There are 2 different motors for telescoping (in and out) and tilting (up and down). Could be 1 motor stopped working. Do you hear motor trying to move or there is nothing at all?
P.S. Lots of electric equipment in our cars and this is the reason I turned off steering wheel memory adjustment during start/stop - just to avoid such issues. I also don't use start/stop mode to avoid starter and battery problems
