Electrical

I live in Wyoming so we still have snow in the mountains.  Last Sunday I got
a 2017 F150 XLT stuck in a small two foot snow drift.  Once I got stuck I tried
rocking the truck, but the transmission would not shift from forward to rear
ward without the truck coming to a complete stop.  After several attempts I
got a fault warning for the limited slip diff. the warning for the power steering,
the ABS, the parking brake, the hill descent, hill start assist, and 4x4 low.  
Additionally the truck would shift in and out of 4 high, but not 4 low.  In 4 high
no tires would move.  In two high only the left rear tire would spin.  Because
of darkness and grizzly bear I had to wait until morning to walk out far
enough to get cell reception.  The temp never got below 34 degrees, but it
did rain and snow all night.  When the tow truck pulled me out of the drift (a
total of 10 feet) everything except the power steering worked.  It was not until
the 3 rd day when the power steering suddenly started to work.  The dealer
will not see me until next week and I am afraid I will loose all the fault codes
by then.  Its great to have a 4x4 that only works on dry ground.  Do you have
any thoughts?
