2014 Ford Focus S radio, clock, and horn not working

My 2014 Ford Focus radio will not play.  The clock always displays (except
when the car is turned off).  It was acting weird, the clock and the date reset
itself to 01/01/2000 and 12:00am.  The clock and date would only advance
while the car was running.  If my clock read 01:45 when I turned it off, and I
came back 5 hours later when I restarted the car it would still read 01:45.  If I
turn the radio on, it only reads Ford Motor Sound System.  I can press every
button on the panel and it will move along.  The menu button does nothing.
All the buttons light up when the lights are on.  I am so confused on what is
going on.  And the other day the horn started not working intermittently.  
Sometimes I can press the lock button and it will sound some times it will
not.  How do I fix this??
