Drove to store fine.  Come back and it won't shift out of park.  Have to push in the little switch next to shifter.  Back-lighting in console and cluster work.  The needles, trip, and speedometer don't work.  Climate controls, auto dimming rear view mirror, heated seats, cruise control, sport mode, and paddle shifters don't work.  Radio still does though.  Sounds like engine fans are spinning at max speeds even when at idle.  Noticed that i can now feel the power steering going from highly assisted to normal now at random times when it was only normal all the time before.  The gps looses signal and regains it at random times if i set a route.  Have codes but no check engine light.  The little key symbol is the only light lit up  Car seems to drive normal with MAYBE just a little less power at takeoff.  No blown fuses that I could see with the ones I checked, including the ones next to the battery, that I think might be related to the symptoms.

Codes pulled with 2 different scanners were P0500, Vehicle speed sensor malfunction, and P0463, Fuel level Sensor 'A' circuit high.  2 other codes pulled with the Hypertech tuner were P1574, ASCD vehicle speed sensor, and U1001, Invalid or missing data for primary id.
Does anyone have any good ideas of what this might be?  I'm trying to avoid having to go to the dealer for this at all cost but I'm stumped.  Thanks in advance.
