Could this be related to the 12V battery failing and not maintaining a high enough 12V bus voltage until the HV battery charges is sufficiently? @Andrew.cc and @mcarvin ? Did your fixes involve a new 12V battery and/or some TSB's? Looks like my year-and-a-half old 2019 Fusion Hybrid's weird electrical problems with climate controls and radio display on the large screen have culminated in a 12V battery failure completely bricking the car. I'd be interested in your findings.

2019 Ford Fusion Hybrid, was developing some odd Radio and Environmental controls issues about a month or two ago: The Radio seems to have entered a mode of less graphics detail, chunkier fonts, and squarer "boxes" but still works. When I hit the defrost button (not max defrost) I used to get a pictoral display to be able to change where the air is coming from - now, a blank box. Next, for the past week or two, we have been getting notifications on starting the car that it had been left on (it had not) and had shut itself off and gone into a battery saving mode. Otherwise it ran normally. Last week, the FordPass App was posting notifications to my phone that "Remote features disabled for battery optimization." Last such message was today 3:25PM Today at around 6PM I got a call from my wife, out of town and stranded because the car was completely dead: no unlock, no keypad access. Called CAA (Canadian equivalent of AAA) and got it boosted (used key to remove trim piece on driver door handle to access a traditional lock cylinder for the key). Boosted, and the car ran normally, but we don't understand why or how our year-and-a-half-old car is already a brick. Now we see. I would have hoped Ford had fixed this by 2019! Suggestions? Newer threads? TSB's relevant to 2019? Thanks all!
