Lost of issues

[FrostZ34]

Hey guys,
This morning when I started my 2014 370z it started up fine and then the gauge needle lights went out (the needles still move but they don't light up). Now whenever I shut it off, the rpm gauge stays just below 1 and the battery voltage gauge stays at 13.5. When I start it, instead of the needles fully deflecting, they stick pointing straight down for a few seconds, and all the info on the car is reset, including the clock that defaults to 1:00. Looking into it more, I found that my OBD 2 slot isn't working, and neither is the chirp when I lock it using the button on the door handle. I haven't done anything to the car for a few months, I've been daily driving it, and I had the battery and alternator checked and they were good. PLEASE HELP!
