PacHy ‘wakes up’ and then shuts down

Has anyone else observed this behavior? After driving the van and then stopping, moving the transmission selector to ‘P’ and pressing the power button to shut down, I am sitting in the car for a few minutes. Suddenly, out of the corner of my eye I notice a flash of light. The UConnect screen lights up, the instrument panel lights up, the ‘P’ on the transmission selector lights up, I see the Chrysler logo on the UConnect screen, and then it all shuts down almost as fast as it came on.

This is a little puzzling to me and I have observed it at least 3-4 times (on different occasions). It makes me wonder if the van might be doing this periodically while it’s parked and completely uninhabited. Perhaps this could be an explanation for why my 12V battery was depleted after 14 days sitting parked at the airport.

Any ideas?

Yes, I see all kinds of weird behavior from the software. I'm pretty sure the infotainment and powertrain control software was written by plumbers. I was thinking 2nd graders, but it seems too complex a task for 2nd graders...
