Has the overarching solution to the dying 12v batteries been a software update? When I bought my '12 FFE last December I started having a dead battery a couple months later. I chalked it up to a bad battery. The car had a fairly new (dated 2/16) battery in it, but it was a cheap no-name battery. So I replaced it with a Motorcraft battery about a month ago. Everything had been fine until yesterday. When out to start the car and the radio did the "System off to save battery" message. The headlights flickered on and off and the traction battery contactors chattered. I gave it a second to calm down, turned it back off, and then back on and it managed to get itself going. Then I got a yellow wrench warning which only lasted 30 seconds and the light turned back off. Then myFordMobile notified me the battery was low. Thanks for the super timely update. I feel like carrying a boost pack is just a massive bandaid to an issue Ford should have been able to pin down by now.
