So as a fun little side note while my mme gt has been sitting in the shop for a month I get to see just how much the car loses while just sitting.
In just about a months time the car has lost about 20 miles of range. I’m actually a little taken a back by it. You can let our 22 bolt sit for that long and maybe get a mile or two less
Of range.
So is this loss from some sort of conditioning that the car does for the battery every now and then. Seems like more loss than should be normal?
Car is in SoCal and if anything it’s gotten warmer since we left it at the dealer a month ago.

From 48 percent to 43 percent roughly.

If they are keeping the key in the car or close to the car, it could be keeping various systems awake. This would drain the 12v battery and could cause the system to use HVB to charge it up.
In my experience, when the key is close to the car, the car drains about 20-25% of the 12v battery a day. It takes about 1-2% of the HVB to maintain the 12v at a decent level each week.
When the key is far enough away from the car, then it only drains the 12v about 5% a day and the HVB would hardly ever be used.

4-5% HV battery use isn’t nuts for a month. Some systems run all of the time and create small vampire drains. Some systems come online once in a while and use more power but only for a short time. Of course, if they’re opening and closing the doors occasionally the lights, screens, etc. are also going to cause drains. ??

Thanks for the info. The car has been sitting in the same spot for over 3 weeks as they don’t have the parts to fix it.

As an additional data point, I left my car garaged and not connected to our EVSE for 3 months this winter and only saw about 1% HV battery drop (50% to 49%). I did have the 12V battery connected to a charger during this time. The garage temp changed little during this time.

That's what I saw as well. But I was also querying it almost twice a day to see where it moved to on the lot and if it'd actually been driven. The often 'wake up and tell me the tire pressure and full car status' from FordPass doesn't help.

Dumb question, do you have any departure times set?

No. Never had a chance to set any of that up before we had to take the car in.
