Need Help with Locks and Radio on 2012 Hyundai Genesis

I am currently dealing with both my locks and radio in my genesis. It started with my radio deck. everything was working until for the past couple of weeks. When I turn on the car the radio is doing one of 2 things. It either doesn't turn on and my clock is reset and stays that way. or after driving for about 10 minutes or so it does turn on and all my presets are gone and the clock still resets. I thought this was possibly a fuse problem until last night my locks didn't want to move at all along with the internal lights didn't want to turn on. BUT when I started the car this morning the locks and internal lights worked only when I start the car??? HELP please

Maybe the BCM for the locks and lights. Radio is independent of that though..

I would reseat all the connectors, radio and BCM. BCM is located behind the center trim below the radio.

A slow battery drain will cause weird things like this.

I mean, battery drains to the point that it's completely flat. You replace the battery, and then weird things start to happen.

If it starts fine, then disconnect the battery for an hour to do a hard reset.

With a slow drain until flat, some of the parts in the computers in the car will shut off before others... they don't like to do that, then weird things happen.
It seems to like being hard cut from power, not a slow drain.

Id replace the battery with a new or borrow a known good one and see if the problems go away.
