my yellow exclamation point came on last night and at the same time, all of the interior lights; none of it will turn off with engine running and the warning menu says there are (0) warnings. Any clue what could be wrong?

I would look first to the wiring harness running along the sill in the driver's footwell. There are three or four wires there that are terminated by the factory poorly, with all the others just running through there. Those that are capped tend to corrode when water gets in because of poor drainage. There are some DIY on it, and it is a pretty easy job, especially if you can solder. When those start to corrode, all sorts of weirdness goes on, including the things you mentioned
