Prius turning itself on by itself and resetting trip counters and clock

Hello!
I have a 2011 Toyota Prius with 200k miles.
Starting yesterday my car will turn itself back on into accessory mode all by itself after I turn the car off, and it will reset all of my trip data and the clock is reset. The car starts up and runs like normal, but the past few times I shut it off it turns itself back on and resets everything.

I already checked my 12v battery a couple of weeks ago because for the past few months the TPMS warning light will randomly come on and flash and then turn solid. I read that this could mean a battery in one of the tire pressure sensors is bad, or could be a problem with the 12v. So I took my 12v to AutoZone to have it tested and they said it was in great shape.

I tried searching the Prius chat and it seems others have had their car do the same things where it automatically turns back on, but none of those threads ever updated with the cause/resolution.

Does anyone have any ideas, or have had this happen and resolved the issue?

No error codes on my OBD2

 

So update, all the connections to the battery are solid, but as soon as I got to my campsite I turned my car off and for about one minute it was completely dead and wouldn't turn back on, then it suddenly regained power.

So now I'm nervous

 

Is this an actual thing?? Because I have a Jackery 1000 that keep plugged into my car so it can charge while driving.

 

Thank you! I just read that thread and I think this is exactly what is happening with mine. I've unplugged my Jackery and everything seems alright so far. I'll update if the problem persists without anything plugged into the cigarette lighters.
