Cold Weather equals Broken 2012 Volt?

Hello all,

Woke up this morning to 23 degree weather and went to start the 12' volt (it was plugged in all night and has a full battery) and got the check engine light...

From what I have read, this has to do with low battery fluid level. I checked this and it looks fine to me, not full but, close-ish. So that would leave the other possibility of a bad sensor or wiring... else some have suggested reprogramming/updating the car with software... (im trying to go this route and waiting for the part to come in)

I cleared the errors and tried starting the car again... didnt get a check engine light but the HV battery is still grayed out and it went straight into ICE mode...

Question is... am I going about this right and given that it was so cold out, would it be wishful thinking that the error will go away when it warms up?

My 2012 went to gas yesterday 3-4 miles into my trip while going up a hill on the freeway. No ERDTT message and it switched back to battery after a couple of miles and gave me 23 miles of electric with 6 left in the battery. It had gotten down to 30 the night before, but it was 44 at the time it switched over. I have been experiencing PPR messages at times for more than a year and a half, but this is the first time I experienced this. I assume I am getting closer to my 2012's end of life. I might have to start using mountain mode this winter.
