Is my car possessed?

[StevenStowik]

My 2013 Volvo S60 T5 is currently having sporadic issues where I’ll be driving and all of a sudden will enter limp mode and a few trouble codes will appear on the screen. “DSTC Service Required” and “Transmission Service Required” bring two of the most popular. Besides that, “Coolant System Service Required”, “Parking Brake Service Required”, “Brake Failure Stop Safely”, “SRS Airbag Service Required” also seldom appear as well. On top of all that, my speedometer will what I’m calling “wave at me,” where it’ll show my current speed, drop to 0, then instantly show my speed, then drop back to 0. My RPM gauge will drop to 0. And my outside temperature will read --°F. I have no idea as to what is happening. I have googled my issue and all that comes up is this same exact issue with a 2004 Volvo S60. Absolutely nothing about a ‘13. If anybody would be so kind to help me understand what is going on or tell me what I could do to alleviate this issue, I would be extremely grateful.
