So just before the holidays I hit the dreaded HVBJB problem. No worries. The dealer has been pretty good to me. They did a copis order for a new HVJBJ for the GT, and 2 weeks later, presto. I'm expecting my car back soon.

Now they are telling me that as part of replacing the HVBJB they found resistance over the main battery harness and need to replace that. (no outlook yet, but non-copis orders show an infinite order time...I'm thinking that's not good).

Any of the more technically plugged in folks know whether the main battery harness is somehow related to the HVBJB? Or is this likely a manufacturing defect that I got lucky they found now?

I'm hoping the harness comes back soon. I miss my pony.

On the dealer side, I've got nothing but good things to say about them (so far...). they put me in a loaner (it had 5 miles on the car when I drove it out of the lot.. Who does that?), and while I hate going to the gas station, I can live with it for now.

For those in the upstate new york (rochester) area I've been using Van Bortel ford. I think they are really making an effort to be an area-wide dealer that specializes in electric cars. The technicians seem to be on point, they understand customer relationship (didn't try to do a dealer mark-up when I bought the car), So far so good -- knock on wood.

Thanks,
Mike

So I appear to be in supply chain hell. It is 2 weeks or so on and I still have no date for getting the main battery harness. Some issue with the supplier, and nothing in stock. Copis order made, BEV team notified, but nothing to be done.

Anyone else have any experiences with this part?

I may have the same issue as well, my dealer tried to order the part and no eta. Today I contacted my BEV rep and did not receive a response.

Hope you are able to source one.

It's crazy. Can't they take parts from the manufacturing line?

I've got the HVBJB (got it in about 2 weeks for the GT part after a Copis order). But for some reason this main battery harness is in short supply. From searching the forum it doesn't appear that a lot of people are seeing a failure in this part, so I'm not sure what's going on.

You jinxed it ? Sorry your experience has taken a turn for the worse.

Well crap! I guess I get to join in your pain. HVBJB triggered today with a 21 GTPE with ~15,000 miles.

Maybe I won’t have the additional issue and the additional part you’ve needed without an ETA, but my luck hasn’t been the greatest lately.

When the HVBJB failures first started heating up, getting a replacement was very slow (IIRC, in some cases it took multiple months). It appears that once Ford realized they had a really bad issue and produced the newer beefier HVBJB, they rather quickly ramped up HVBJB production to meet both their ongoing manufacturing needs and replacements for failed parts. My guess is that battery harness failures are really rare, so there isn't much/any repair stock available. As for grabbing one from the production line, it's been said on other threads here that that just ain't happening. Very sorry for your experience - that really sucks.

BTW, I've heard others have gotten Ford to both make their payments while the car was down, and even pay for gas. You evidently need to fight a bit for it, but it does happen.

Good luck

I wonder if Ford ratcheted up the sensitivity of the heebyjeeby detect-o-matic software patch, so it's flagging a whole new batch of potential failures. It would be a good way to manage flow, at least. Mine went in last Friday morning, there are 2 in front of me before mine even gets looked at. Apparently, all showing the same issue (though I'm the only GT I ever see around).

If they're going to be beefing up the main harness, that could be a big step towards removing the 5 second penalty. Entirely conjecture, here.

I believe the bus bar within the battery bank may be the ultimate limiting factor so I doubt this will help the 5 second limit but one can hope.

Based on what my dealer said I am wondering if they are changing parts for the main battery harness. Is there a way to tell if the revision # is changing? (like it did for the HVBJB?)

A wiring harness meant for what they are currently manufacturing ('23) wouldn't necessarily fit your particular model year. And even if it did, they aren't throwing their production schedule out the window to fix cars that they have already made their money on.

Is there any way to find out how many cars out of how many built have experienced the HVBJB failure ? Is it possible that regardless of what model 2021 or 2022 build year one may never have this problem ?

My previous 21 Mach E (now I have a 23 Mach E) had the HVBJB recall and the letter from Ford only said to wait for the OTA update to fix it. I never had to change any part in the car. Maybe mine was different build? I have no idea.
