System off to save battery

Confirmed!

You should install the latest BCM update and see if that fixes it.

I did all the FDRS updates in Aug plus received two OTA’s since then. Do you know the latest software number for BCM?

It’s showed up since then. You’ll have that and powertrain updates to do. Did mine a couple weeks ago.

What is a BCM update and how would you install it?

Body Control Module. You install it with FDRS (he installs his own updates). There isn't a TSB for your dealer yet.

I’ve been getting this message as well. I charge nightly and drive 40+ miles daily. I don’t use the widget…. I’ll try turning off the welcome lights to see if that helps.

Update. Turning welcome lights off didn’t work. For about a week I received this message every time I turned off the car, regardless of charge level or amount of time driven (including a few hour+ drives). I was worried about getting stranded, but the car seemed to work just fine. The annoyance was that remote start wouldn’t work with the car in this deep sleep.

I got into the dealer yesterday and they ran some diagnostics and said the battery was faulty. They replaced the battery under warranty and so far so good. I’m still worried something was draining the 12v and this message will return in a few days… I’ll update in a week. Hopefully it was just a bad 12v.
