Wow. I've had a dead battery so many times because one of the many interior lights were left on. (They're hard to notice through the rear tinted windows.) But, if the software is turning off all the lights, I guess that problem essentially goes away.

The parked scenario for 2-3 weeks scares me. There are many times I don't drive this vehicle for 3 weeks, or even longer, at a time. That probably will still be true when I eventually replace it. I hope I will have a reasonable solution.

Both vehicles will turn off the headlights (or radio or dome light etc.) if 
left on for more than ~15 minutes.

But... both had 12v accessory outlets that remained *on* when the car was off. 
Leaving a cellphone charger or other gadget plugged into them *would* run the 
battery down. Or, just leaving it parked for 2-3 weeks.

And if the battery ran down below 9-10v, the "immobilizer" alarm would disable the vehicle 
completely. Charging the 12v battery didn't work, and it could not be jump started. Turning the key to the 
"start" position would crank and start the engine, but as soon as you release the key to 
"run", the engine stopped, and an alarm message was displayed. The only option was to have it towed 
to the dealer. No kidding!
