AWD, ABS, TCS, etc errors

My car does not appear to be happy with cold weather and I'm not sure what's going on.

So I know about the drive modes having issues when the car starts in freezing temps (which is ridiculous enough but whatever, at least it works).

Except that now my car isn't working. I wasn't drifting in the snow, racing, anything. It tends to sleep in a garage at night except for very rarely when I need to leave it out for one reason or another. Anyway, I started my car up in my driveway and basically everything isn't working: ABS error, AWD error, traction control error, hill assist error, naturally the drive modes are disabled as well. The car does start and does move but it's a front wheel drive with too much torque, no differential, no traction control or ABS in the winter. So while I could probably get it to the dealership the safer decision probably means having it towed given the snow and ice we have here right now. The weirdest part is less than 30 minutes earlier the car was out for a shopping run just fine. The temps hadn't even cooled all the way down and yet here we are.

There are no typical "service" errors however, such as a check engine warning.

Naturally I've tried bringing the car fully to temperature, shutting it off and on (with various delays in between), etc.

Anyway, I was wondering if anyone has had this issue or can think of a solution before I take it in. Is there a sensor of some kind that might have gotten dirty? Something like that. On a normal car I might try disconnecting and reconnecting the battery but I'm unfamiliar with the special battery type/system in this car and I wasn't sure if that was a good idea.

Thanks in advance to anyone who can help!
