Assuming you have a deluxe model and not a Trail or Forest?
If so the drive mode issue could be a cable adjustment, since none of that is electronically actuated. Also check under the hood to see if the hardware that holds the cables to the shifter linkage is there and tight.
The Acc. Socket is probably unplugged, its also under the hood, but down under the fender. Did you have any accessories installed before taking delivery, its possible they may have left it unplugged installing a winch.
The MT/AT is most likely also a disconnected switch issue. Again that plug is found under the hood. Be aware that it will only switch between modes in HIGH or LOW and not park or reverse.
