Good to know.
In my climate, dealers install a factory trickle charger with a built in charging port under the front bumper (you can barely see it). I've plugged it in overnight a couple of times in the past 3 weeks just to make sure the battery doesn't discharge too far. I haven't seen a warning message in my car yet. We are going on vacation for 2 /12 weeks next weekend and I plan to leave the trickle charger plugged in while I'm away.
I always lock the car when I leave it to make sure everything shuts down and goes to sleep. Hopefully I won't have a problem. Seems crazy to have to plug a modern car in, when we haven't had to install block heaters in our cars since 1998, but I guess all of the electronics place allot of demand on the glass mat battery.
