I drove the car Friday.
I went away for a few days, not back until tomorrow night.
Today is Tuesday.
I've gotten several messages on my phone that my battery is low/critical.
How is this possible?
The weather where the car has been is about 60 degrees.
This is a new car which was purchased last summer.
Seems odd that sophisticated electronics and software can report a depleting battery, but can't do anything to anticipate and prevent it. My understanding is that charging systems now take batteries up to less than full charge -- about 80% -- for fuel economy. On top of that, the car's electrical system continues to draw a bit of current when parked and locked. Frequent short trips can have negative effect. Or maybe the battery is headed for premature failure, or was not maintained on-lot at the dealership.
Drive to an auto store or to your dealer and ask for a battery analyzer test.
Doesn’t look like I’ll be able to drive at all when I get home tonight. Like I said, it’s only been 3 days of not driving on a new car.

What I would do is put the car in standby mode, unless its parked where you need to have the alarm system active. In winter I put mine in standby in the garage, and then supplement with a trickle charger. I don't know if this helps you.
It isn’t even cold. This is Las Vegas. Yes, it’s in a safe place.

Make sure to lock your car every day... double click the lock button. That way the car battery and the car are not transmitting any signals while parked. And get a trickle charger just in case.... But it may need a trip to the dealer, just in case. My W206 stays parked on my driveway days without driving it, and it has zero battery issue... knock on wood.
I've been having this issue for a while. When it happens I charge the 12v battery overnight, but it's not normal.
Now my car is at the dealership for the fuel pump recall and I asked them to investigate on this as well. I should get the car back tomorrow.
