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

[Guss-E 2021]

My HVBJB failed on Friday the 13th of October, was at the dealer Monday, was ready Friday. Very happy to have my car back and the service experience was great.

I do agree it seems like a lot of HVBJB failure have happened in the last week, which is odd.

Jealous you already have your car back. I swear I'm going to punch Sheeba for throwing up random, extra error codes thusly extending the time of repair (the HVBJB replacement was done in a day).

Regarding the failures, it seems there are varying degrees from potential failures all the way to fully fused contactors. I'll have to remember to ask if my contactors were actually fused.

That’s a bummer, but at least the big repair is already done and you’re not waiting on the part!

You can actually get the frunk button anytime, you just might have to pay the dealer to do it like I did for my First Edition. All it needs is the updated BCM and GFM modules which allows them to check the box enabling "electronic front trunk release button". I took my FE to the dealer and specifically instructed them to do this and the tech was able to do it just fine...they also have a tech hotline to corporate if they're not sure how. My dealer charged me $199 cuz it's not a mandatory update, but it was totally worth it to me cuz as soon as I got frunk functionality I got a Lightning fob and programmed it to the car so now I can open the frunk anytime from the fob which I use all the time.

I had all of that done as part of my 10k (after 13k) service. They did not "check the box" but I had it on my FordPass PAAK just not on my Sync screen. They only charged for rotating the tires. Like you, I ran out and got a Lightning FOB on eBay as recommended here (Thanks!). I don't care that Sync doesn't know about it as Sync is so slow that by the time I park the car, turn it off, change to the screen with the button on it, wait for it to become active, someone has opened a door and the screen dies. Now I (sigh) carry a FOB, removed PAA(sometimes, maybe, when you aren't REALLY counting on it working)K, and am overall a happier Mach e owner.

Yes, trying to remain patient and positive. I just hate this ICE loaner so much.

What type of HVBJV Ford use on the MachEs built after May 24, 2022?

 

[Valkyrie]

The second generation ones were installed on those newer cars and the new HVBJV parts were 'beefier', and supposedly fixed the problem. Doubts remain.

It depends on how you define the problem. I believe Ford and the NHTSA define the problem as leaving the driver/car in danger when the issue happens. The software 'fix' was to prevent catastrophic failure that would shut down a vehicle in traffic. The newer part was to make it less likely to trigger the software 'fix' and to eliminate the catastrophic failure. Viable 'fixes' for the problem as defined. Not necessarily viable for the consumer that believes every MME will eventually have a HVBJB failure.

Based on other people's posts, Ford is still diligently researching the conditions that push the HVBJB beyond its limits (a different, less pressing problem for Ford) to begin with. I doubt any existing vehicles in the MME fleet will see a revised part that eliminates the less severe failure that doesn't involve limiting performance. They've beefed it up and are likely hitting packaging limitations within the vehicle's overall design.

Your position assumes the root cause is an engineering/design issue as opposed to a manufacturing defect in the contactors.

There have already been failures with the 2nd gen versions are they also manufacturing defects? Ford sits towards the top of the table when it comes to recalls for a reason this will not have been the first or the last time Ford will have used an under spec part and needed to correct it later down the line.

 

[hack-e]

One further question: if the same part will be used for this recall, why did Ford tell the dealers to wait until Ford provided parts ordering information before any new cars subject to the recall could be delivered to customers? It seems like Ford could have just told them to fix the cars with the existing part.

This is the part that gives me a little hope that there could be a new fix. Even though NHTSA only requires the already deployed updated parts, would it behoove them to replace with a third even better design to stop the failures completely since they have to touch every car anyway. I assume Ford would be allowed by NHTSA to replace with an even better part.

And wow, my car was manufactured in late March before the new par and software recall. I took possession at the start of May 2022. When did we get the software fix? 2 or 3 months later? And I drove it fo another year after the software fix before failure. Hmmm.

Being the huge optimist that I am, I am thinking that Ford is replacing the HVBJB with an updated part that is a lot stronger than the current part (and reman parts). I hope that is why they were so eager to get my data tracking info so that they could use that data to test the updated part to make sure it could hold up to my unique driving out in the country.

If that holds true, that would explain why cars like mine who have already had the "latest" reman part installed would still need to have the recall done. Again, the optimist in me says they are starting with all the GT and extended range MMEs built before July, 2022 first because they are the most prone to failure. Once a good portion of those vehicles have completed the recall, I would not be surprised to see that recall expanded to include the rest of the MMEs.

It really is too early to tell for sure, but I am sure once the recall is finally released and parts are available we will know a lot more. Let's hope my optimism holds true.

I do agree it seems like a lot of HVBJB failure have happened in the last week, which is odd.

Mine failed on the same day and the dealer hasn't been able to look at it yet. They only have 2 electric-certified techs, who happen to also be their only diesel techs, and are pretty backed up.

I recommend to anyone else who has to wait a while to contact Ford customer service BEV dept. They created a case number and called the dealership on my behalf, which helped the dealership find a loaner car for me (which they told me they were out of). It's a Bronco Sport, so its kinda fun, but I miss my Mach-E.

I should hear back today or tomorrow from the dealership on what's going on.

I really don’t care if they do or not. I got the part cheap and replaced even cheaper so it wasn’t a big deal. When I get some time next month I’ll look into it.

If you actually get reimbursed, I will really regret not following your lead to lower my trip anxiety. (At least I don't travel the Grapevine, see goats, or listen to young kid's tunes on my trips! And if this doesn't make sense to readers, you haven't been reading this forum long enough!)

And I'm at least a 3rd person who's failed on Friday, 13 Oct. And despite my service advisor last Thu saying that the tech did not think my SVS, H-VB Warnings, Powertrain Malfunction / Reduced Performance were not related to the HVBJB, early this morning he confirmed that it is indeed the HVBJB that needs to be replaced.

Once this recall is released, I wonder what that is going to do to the wait times at most dealers for EV work. I also wonder how many dealers will say, "We don't have the staff/tools" for the recall and advise going to another dealer.

I know my dealer doesn’t have the equipment to perform. It took them 2 years to finally get wind shield done and that’s a disaster I’m still dealing with.

Having no issues with the HVBJB in my Premium EX. Waiting patiently for the replacement contractors to arrive along with the recall letter.
