A bit of a TLDR from some who had been through this and knows the saga:
The battery is fine. The issue is the part responsible for connecting/disconnecting the high voltage battery from the rest of the car when it’s off.
The relays can overheat from high current and weld open or closed. This is more prevalent in the higher performance models. Higher external temperatures, flooring it, and DC fast charging can all be part of the equation. Hit the wrong combo at the wrong time and… you lose the lottery.
This has been known for quite a while. Ford had a new part that fixes it which all the new vehicles had. But older cars weren’t given it until it failed (like mine). This has been a very sore spot with owners.
This recall fixes that. And it’s good they’re doing it, though way later than they should have.
There was a software update to “fix” the issue but it didn’t work. I think what it really did was try to help ensure the cars could limp to a dealer if it happened instead of just refusing to start. I’m not clear, but it’s well known in the community it didn’t fix it.
