Radio/tape Cd Player problems of the 2015 Buick Encore

"takara recall" my 2015 Buick as been doing diffrent things. First the blinkers and radio went out and then it came back and now none of the doors lock worked. I was stuck inside my car for 30 min. Now the ignition gets really hot. And the doors won't unlock in the back. Im concern about what's going on. While driving the signal wasn't working neither the radio but out of nowhere it starts working. It's been doing it on and off for the past four or so days. The key is getting very hot to where it almost burn me. Very weird. . . Im truly concern about that. And I was in the car when the door wouldn't unlock.

*many times sitting still or going down road screen goes dim and sometimes almost black (whether headlights are on or not) *screen has went completely off * headlights comes on when not needed, and doesn't always come on when needed, going down road *alert lights in mirrors doesn't always work going down road *sitting in school parking lot with keys off the radio comes on by itself *sitting in sonic parking lot and when I went to start car I had nothing. I kept trying it and finally it started *bluetooth doesn't work properly, you can call out or you can receive calls, you can hear them but they can't hear you *passenger airbag light doesn't always come on.
