OP here. I do hook up a battery tender sometimes - but for my car - this is an unrelated issue.
The message is saying that the battery was draining while car was off for some reason. The message is not saying that the battery is low. You battery can be 100% charged (as shown by tender/multimeter) and you can still get this message. Interestingly - I never get this alert in the summer - only in cold temps.
I get the alert less often after they changed the comfort access handles but I still get it. The rest of the car is amazing - but this issue does not want to die.
If your dealer does figure it out - please share it here. So far - 3 years in - I do not have a real fix for this.
