Keep in mind that the HVBJB also can fail for reasons besides what we’ve come to expect. We had one forum member who had a failure a month or so ago that was unrelated to wot and DCFC.
Yeah not the post I wanted to read just before going over the mountains again to get home to the Bay Area, although failure of the redesigned HVBJB still has to be relatively rare at this point.
Interesting. While it should be able to handle this or any other driving style users can throw at it, perhaps the answer is it can't. That would be unfortunate. But since I'm about to turn 70 and my WOT days in any car are long behind me, I won't worry about it for myself. I hope you get it solved - or if it can't be, that you find a vehicle more suited to this sort of driving.
I don’t think you are close to 6,000 miles on your new one yet so you should be good for the trip… Plus now you know what dealer not to go to ?
At least you could get a newer one, hopefully built AFTER May, and a fresh start. Regardless, I am very sorry to hear you are having this experience. You must be very good at getting this fixed at this point!
Unfortunately I do not think it will matter. Ford replaced the HVBJB with the current updated HVBJB in September and now 5,000 miles later it looks like it has gone out again.

Did you opt into extended warranty?
About 4500 miles right now since the new design one was put in, about 700 more in the next couple of days ..... ? and a BMW i4 M50 that just got a production allocation for delivery in April if my junction box fails again before then.
Oh yes. Even though I knew the HVBJB is covered under the 8 year/100K HVB warranty, I used my Ford Pass Points towards a Ford ESP through Granger Ford who advertises here on the forum. I figured since their pricing is under $1K for doubling the factory 3/36 warranty on the car it was a worth while gamble given all of the possibilities with this EV. I actually signed up for that even before my first failure ?
OP got the DTC codes for SVS due to contactors -- it's nothing else other than the contactors failing in the new design IMHO.
Your use case outlined here has to be an outlyer -- not that this excuses what probably is a fundamentally under-spec'd battery pack design of our cars.Unfortunately I do not think it will matter. Ford replaced the HVBJB with the current updated HVBJB in September and now 5,000 miles later it looks like it has gone out again.
The main problem is I have become hooked on the EV performance and driving characteristics. I spend a lot of my days off out in the country with wide open roads with lots of hairpin turns, huge elevation changes and lots of 4 way stops in the middle of nowhere. I have been known to go through 80% of a battery charge in one trip and almost every trip lasts well over 90 minutes (some are several hours). Although I am not at really high speeds, I am regularly around 55 mph and coming out of tight turns and 4 way stops I will be at WOT several times during the trip. This is where most of my miles come from since work is only 8 miles from the house.
So I am really stuck here. Since I absolutely love the car and right now there really isn't an alternative EV without spending 10s of thousands of dollars more getting something else. Also, even if I did find something else that would not guarantee I have a completely trouble free experience.
But fortunately I have a great support group here on the forum, we still have an extra ICE vehicle here at the house I will be able to use again during the repair and I am sure Ford will get my MME repaired once again and back on the road soon. All things considered things could be a lot worse. The worst part is going back to ICE. Every time I do, I am reminded just how much better the EV experience is and it makes me want to go back to the MME ASAP
? I actually have been looking at the i4 M50 as well. I just don't know if I could pull the trigger just yet. Our local BMW dealers are stacked up on work and even a routine service can take days before you get it back. I can't imagine how long something more complicated would take. Plus I really like the looks of the MME, where the M50 not as much. But, then again, if this keeps continuing I might just overlook the looks of the M50 ?
