High Voltage Battery Junction Box (HVBJB) Replacement Recall for recall HVBJB in 30,013 Mach-E

[Mach-Lee]

They told me the RM on the end of the number in the TSB stands for re-manufactured. Not necessarily starting with prior failed parts, as unused replacement parts were also “re-manufactured” with better contactors. No way to know exactly what got put into my car, though I suspect most of the failed parts were just discarded by the dealers.

That is correct, they have switched to remanufacturing the HVBJB. Basically when they get a returned core, they unbolt the original bad contactors and install the new revised contactors into the same HVBJB.

They better get their part situation figured out. My car has been sitting at the dealership for over a month now with NO SIGN of the part arriving yet. If this recall goes out, they better have the goddamn parts available.

My experience has been an absolute shit-show (pardon me).

Crazy how different dealers in different locations can be worlds apart. I dropped my car off for the failure last Monday afternoon. Tech on Saturday verified the issue, ordered parts, they arrived today and they expect my car to be finished by Thursday or Friday.

That was pretty much my timeframe- Towed into Ford Monday 9/11; got it back all done Friday 9/22. I was lucky enough to get a loaner car too (Ford Escape).

No one got any notice yet. Did you check your VIN on Ford’s website?

Ford is not interested in "notices". I have not received a single notice yet (glass, fob, BC, etc.). Only reason I knew/know about them is via this forum.
If Ford were to send a "notice" for this it would be out of character.
Not holding my breath.

Because of this part:

So Saturday morning I charged 40 minutes at EA in Barstow, ca heading south bound on 15. In number 1 lane in Hesperia, ca lost power
Lucky it was clear to get on the right shoulder. About 10 minutes was able to get it going and got home.
Took it to Chino hills ford, the service advisor says it's a bad fuse box. 21 extended range GT.

So if my dealer ordered my new HVBJB on Monday, I can assume it’s a “newer” part that will be less prone to failure?

Yes, Ford purged all of the original part over a year ago. That was part of the reason that HVBJB replacements took so very freakin’ long in early summer of 2022. ?‍?

Cool. I'm sure that Ford management realizes that replacing all old design HVBJB is an essential step to lifting the 5-second power limit of the GT/GTPE

It isn't a five second limit.

Does anyone by chance know if the recall includes EU models? They have same production site
My son just bought a MME AWD SR Premium built Aug. 9, 2021.

It is a USA specific recall. I expect they will also provide the same recall to the EU, but they probably have to follow EU recall regulations, which are much different from those here. Government regulations make everything harder than it needs to be.

Unless your son is frequently traveling at high speeds, I doubt his car is a high risk for failure. From data collected here, the most common cause is 90+ mph driving, especially 80+ going up a long incline. If he rarely exceeds 100 km/h, the risk is low IMO.

I am tracking all of the 21 GT or GTPE cars that as of a month ago did not have a failure. You should be on that list, if you are interested. Let me know.

https://www.macheforum.com/site/threads/2021-gt-gtpe-mmes-without-hvbjb-failure-tracking-list.30158/

Per the poll in that thread, the defect rate is 50%. I expect it is higher. No wonder there is a recall. Finally.

New advanced notice to recall HVBJB in 30,013 Mach-Es

So exactly what does this mean? That all cars in the range given will be recalled and have it replaced?

Or in my case I dropped my car off after-hours on a Tuesday, the replacement part arrived Wednesday, and the removal/install was done on Friday.

Yes

So I happened to stop in at two Ford dealers today for another project, not in my home state, and both dealers had the contactor recall pulled up for my car as soon as I gave them the VIN.

I am writing this here to let us affected folks know that we don't necessarily have to await a physical letter... it appears that every Ford dealer out there will already know if your car is affected.

Of course, they are all "awaiting parts" etc.

They know about it but aren’t scheduling anything at this point , as I called today about the charge port CSP

Not really because of the timeline.

Power limits came first

Then came the HVJB issues

Then came an announcement to change the limits

Then came the recall announcement


At the very least, they seem somewhat unrelated.

That and the HVJB issues affect all models.

My theory is that the recall may delay the power change update though.

I actually don't think the timeline necessarily precludes the theory. Ford must have known that the contactors were near the limits of acceptable, though they presumably didn't anticipate just how shitty they would end up actually being. Those on-the-edge contactor specs could very well have contributed to the 5-second limit.

The announcement to modify the 5-second limit could very well have been with full knowledge that the recall was coming (or perhaps even an attempt to try to force others at Ford to agree that the recall had to happen).

I have no inside info on this, but my guess is that those of us who have had our HVBJB replaced since May of last year will ultimately be told that our recall will consist of whatever the new PCM, BECM, and SOBDMC software update is that is mentioned in the recall advance notice.

What's interesting is that no one has talked about what the revised software might be. I'm wondering if it might be what actually changes the 5-second limit...

 

[Fixbear]

Interesting. Mine is on the list even though me HVBJB was replaced just 6 weeks ago. My guess is that Ford's records aren't up to date on that front...

We seem to be placing all the focus on the Contactor unit. But they also mentioned replacing more modules. Could this be the missing link?
