Define high speed. Is it over 70, 80, 90? Or people just said they were going quick?
You have no battery issues.
If I recall correctly, its just not high speed, but rather passing (?flooring it) to pass while at sustain freeway speed.
There is no definitive way to trigger the failure. PERIOD. There are practices that MAY cause the failure to be more LIKELY. DC fast charging followed by WOT might be one.
No absolute way to cause a failure at any one particular time, but definitely increase the likelihood of failure base on certain actions. Like smoking, doesn't guarantee you'll get lung cancer, but much higher incident than if you don't smoke.
Many of the failures have occured while driving well over 80 mph. Again, this is just the data collected here in the forum which of course is a limited data set, but it is the only thing that seems to be a consistent factor.
I am only referring to the data we have. I am sure Ford has much better data. I am saying we don't have an instance of a failure while it is being charged. Of course it could be a contributing factor, just like WOTs, but I am only looking at what we actually know. High speed has been shown by the data to be a big factor.
High speed under high load, is definitely a contributing factor. But Ford themselves also mention DC fast charging in their recall. So I'll take their word for it that DC fast charging is also a contributing factor.
Nice summary!

Ford is likely also trying to manage supply chain issues for the replacement part. Their supplier was making parts at the rate of manufacture. Now they have to make parts for manufacturing AND warranty replacements. So replacing them as they fail (rather than telling everyone w to bring their cars in before failure) is a cost saving, labor saving, and parts availability management effort.Nice summary!
I am confident Ford has a list of VINs, manufacturing dates, what parts and part batches were used when, what HVBJBs have failed, along with mounds of driving and diagnostic data we all agreed to share with them when creating an account.
I am also assuming there has been and is ongoing statistical analysis (maybe even some fancy ML or AI) that helps Ford understand how many failures to expect over a period of time using the data above. That data could very well say 100% failure is expected, but I suspect not. I think many on the forum assume 100%, and that's fine. Knowing how to handle it should it happen is good information to have, but living with some degree of FUD is just going to damper living life and driving a kick-butt vehicle.
Even if Ford knows it might be something close to 100% failure, they're spreading the labor risk and costs over time based on either some analysis, or maybe a little hope thrown in while running a risk with their reputation. It's the latter where they need to continually come through.
We also have to remember that this issue, while incredibly inconvenient (and frustrating in many cases), is nothing like the Takeda airbag situation where literal shrapnel was a possibility during an accident, and it's taken years to remediate. Hundreds of thousands of people had been driving a landmine a few inches from their face, daily.
Long way of saying, we don't know what we don't know, and just enjoy the vehicle (fast forward to a few days from now when it gets me now that I've typed that
Yeah, thanks for that and I supplied data for the first time it happened. I was doing pretty quick, a pain afterwards but real fun at the time! It is a mustang after all. The second time last week I had been going 70-75, and had a two hour break in Costco before driving a lot slower to the chargers before it broke at the charger.
