2012 Subaru Legacy - Solid check engine & vehicle dynamics control, flashing at oil temp & brake

I was driving down the road in snowy conditions when my dash lit up like a Christmas tree. 5 minutes before the dash lit up, traction control kicked in on a slow turn. I didn't think anything of it except to be extra cautious. All exterior light work fine and engine fluids seemed normal. I let the car rest for a few hours and all lights disappeared when I started it back up. 2 minutes down the road, all the lights came back on. I get all my services done on time and change oil every 4k miles. All the lights work properly. Car is in the shop as I write this but it'll be a few days before they can look at it. I'll update as I get info, posting this more so to help others. Any thoughts/advice is welcome.
