So on the HVJB replacement....if you're using the Ford app there should be a list of open recalls or maintenance actions that would apply to your VIN and you'd be able to see if that action is still open (not completed).

Also, on the Ford owner's site the same thing should be available to you. Right now I have just two open actions regarding the door hems paint issue, and the driver's seat belt buckle,....but if you have any other actions (like the HVJB replacement campaign) they would be shown in the list, similar to below:
Ford_Owner_Recalls.webp


In addition the service advisor at the dealership can simply look up the repair history (both warranty and retail) and tell you what repairs and Field Service Actions (FSAs, recalls, CSPs, etc.) have been done and when they were done.......it's not a frickin' secret. There are a lot of dealerships that wish they never had to deal with BEVs at all and seemingly go out of their way to make it painful. But the reality is they likely have just one tech that's certified (only because they have to), and working on a BEV is not as profitable as working on ICE vehicles.
I don't believe it is an open recall just they eventually fail on all the early cars.

If it’s not on the NHTSA website then the HVBJB recall has been done.
Then this brings us back to why did my car get bricked if the only issue was a 12v battery going bad?
It's the holidays so response from the dealership will be slow. I'm also in MI and both the manufacturers and the dealers hate EVs.

Thinking I either should have spent the money to upgrade my Leaf battery or maybe bought a Kia or Hyundai. At least believe in EVs.

Search "Hyundai ICCU problem" before you jump there too quickly :)

You should consider getting setup to do your own updates using FDRS. I do it once or twice a year & don't have to deal with the dealership. It's not very complex or expensive to do.

https://www.macheforum.com/site/thr...uide-to-updating-your-mach-e-with-fdrs.10217/

I wouldn't say it's inexpensive unless prices have come down substantially. When I checked a couple of years ago, it looked like you would pay around $1,000 just for the equipment if you already have a PC and then you have to purchase the software license.
I thought about going for it but I have never had any issues with my MME. It gets me from point A to point B faster than I need to go, so the home ceo and I voted against the expenses on our retiree's budget.
The OP might want to consider using FDRS but it wasn't inexpensive unless you have links to lower priced equipment that can be used.

I didn’t say it was cheap. I said not very expensive. Compared to paying a dealers over $800 for updating his MME once, he could do it himself forever after investing about $640.
A Mongoose Plus Ford2 interface for $440, & around $100 each x2 for 2 Clore Automotive PL2320 12v Power Supply/Chargers, plus any old Windows laptop. After the hardware investment, you pay $50 for a 24hour license for FDRS software from Ford & do the updates yourself. It’s paid for after just one update. Not having to take your car to the Ford dealership and leave it there for weeks waiting for them to do something is priceless… it’s very much worth it to me. I don’t know about you.

I didn't say you said it was cheap. You said it was inexpensive. My MME has never been to the dealer, so that expense is not necessary. It would not have paid for itself. I saved a considerable amount of money.
A tech did come to my home to do the LVB recall.

My MachE was at the dealer for 60 days to get the HVJB replaced. I’d pretty much give a kidney not to have to leave it at the dealership for anything.. My dealership does not do repairs in your driveway.

When I get to the bottom of the current issue, I'll consider next steps. It does seem though nickel and diming us for bs won't be sustainable.

Yeah I think people in other countries don't realize the US is not pro-consumer when it comes to cars. It's worse since the pandemic and the constant increase in the price of new cars.
10 years ago I could drive my car to the dealership in the morning they would get to it by the end of the day or maybe the next and I'd get it back in a couple of more.
Now I cll them for an appt, it's 2-3 weeks out and it might take weeks for parts.

I just took my 2021 in for service and the recalls. They claimed all recalls were handled except the 12V as it wasn't necessary for my car,, then I got a letter in the mail 2 weeks later that Ford saw I took my car in, but didn't get the 12V recall handled. Getting a bit frustrated with Ford.
I got yet another notice that my update is needed. The notice that the dealer said wasn't for my 2021. arggggg

Update on my car. It looks like it is TSB 25-2058. I believe i just got stuck in a loop. It dropped down into single digits that day I tried to swap the battery and it just didn't have the juice to start the car.
The dealer said they had to use a large external battery to get the updates loaded.
I pickup the car tomorrow.
I am mostly disappointed that the car wouldn't start but maybe having this bug, with a weak battery on a week of 10 degrees temp is just a condition that is hard to solve at home in a driveway.

They are replacing the HVBP in mine. Has to order one. With the holidays I don’t expect anything anytime soon. They already replaced the 12V and it’s not throwing any codes to indicate what’s wrong.
Its frustrating especially for a 2025 model that has less than 1500 miles and I have now not had the far longer than having it.
Update - battery didn’t solve the issue. They are contacting Ford Engineering again. One more week and the 30 day lemon rule can apply. About the same day the first payment is due. Ironic.

My update for the recall has been failing since early December.
I tried charging the 12v battery several times and it never helped.
tried leaving car run with blower on full, no help.

what worked from me (method came from this group):
I set my Emporia charger down to its lowest level (6A) and started charging the car EV battery. (my car is setup to stop charging at 90%).
when I started charging it was early evening and I had a 75% HV battery.
Not sure when it completed charging, but the next morning I went out to car and the charge and upgrade had competed.

I thought I posted the final solution but I must have closed the window before submitting.
Dealer called and told me not to come in yet. After getting some software updates to load it flagged errors telling them to replace the HVBJB. This was replaced under warranty. I was surprised they had it in stock and replaced it that day. Car came home on 12/31 with a small charge for a software updates and replacing of the 12v battery. All things considered, with the holidays, and me slowing them down while they did the research, it was only several days for the physical work. I'm more disappointed Ford has such troubles getting updates done. It was less troublesome to drop the battery and replace the HVBJB than get some failed software updates loaded.
