Thank you.

Haha I meant Malfy's white GT with the red bow on the frunk hood.

My point, based on what others have shared, is Ford has now removed vehicles built prior to May 2022 that have had their HVBJB replaced from the recall list. I am not saying nothing has changed with the HVBJB but I doubt it. I do hope to get a picture of the replacement when it comes in to look up the specs on the contactors. Like anybody I would prefer that the recall gives me a HVBJB with a 0% chance of failure.

Not completely true. Mine was built before the date, had a HVBJB failure and replacement and still shows recall. Their recall language says the following:

If your vehicle was previously repaired for this issue under recall 22S41, the remedy may not proactively detect damage to the contactors on your vehicle and needs this new repair. Similarly, if your vehicle was not repaired under recall 22S41, it needs this new repair. Should the contactors weld closed while driving, a powertrain malfunction warning light will be illuminated on the next key cycle, along with a possible no start condition.

So, off to the dealer someday it will go.

Not to beat a dead horse but there was no repair as part of 22S41. That was just a software update to detect potential failure and then throttle power until you took your car in for repairs. Basically a soft landing versus bricking as had been taking place. Many people have stated their car has been removed from the list but of course we will not know the final answer until recall info is released. But unless there is a “new new” part (which I personally doubt) why would they change out someone’s car who already has it installed? Ford’s remedy states that the remedy part went into production vehicles beginning May 25 2022. Unfortunately Ford’s communication is kind of poor so all we can do is wait and see and speculate in the meantime.

I thought they were also releasing new powertrain software, so they'd be replacing the part and updating PCM, etc. to the latest level, but they're sticking with the existing software then? Obviously if you haven't done the software only recall, you'd get the latest, but those that already did it won't? The software is what seems to be the issue with those that have already had it replaced multiple times...

Why is the software the issue responsible for multiple failures? I thought it was the contacts that could not take the heat and once they failed under purchased power it would kick in. Is there now newer software that will limit power under normal conditions before they fail and therefore not allowing the same performance as it had originally? That is the only thing that software could do to stop multiple failures if the hardware still does not work as purchased. Decrease our L2 charging and our 0 to 60 does not sound like a win win.

Well, if they're using the same part they've already put in my car twice, then I would assume they're getting false failures where the HVBJB isn't really about to fail the software is just being too sensitive. Same with @heisnuts having so many replaced with the current recall software. Unless they do end up updating the part when they start to roll out actual replacements. Unless they're fine with still having these false positives, etc.

There were 107 reports NNTSA of HVBJB failures that left people stranded post 22S41. All but 7 were ER and GT models so Ford is now going to replace HVBJB proactively on ER and GT models. The failure rate was low enough that they are not doing it for SR models (I assume that is the reason.) There has been no information shared as to whether or not any of the SVS errors that have occurred on the new style HVBJB is the result of too sensitive of monitoring software (false positives.) We also do not know for sure yet what the part number is for the replacement part that will be called out in the recall; although, I suspect it will be the same HVBJB that has been going into cars since May of 22.

Maybe they are saying since I have moved on it should not be a problem anymore for the future using the existing updated part. ?

They just refer to you as "Darrel the Destroyer".

Or possibly they are still failing and they are not false positives at all? They are being pushed to fix it and if they have the fix yet is anyone's guess.

So, my car heard about the recall and melted the HVBJB on my way home a couple of weeks ago. Managed to get to my garage, called Ford and the dealer. They sent a flatbed truck to take my GT to the dealership and I left on a trip to Ecuador. While there I got a text message that they found "other" damage to the battery pack and claimed that I must have run over a curb at high speed..... of course, if I had done that it would have torn up the front air dam which is lower than the area beside the front passenger wheel where they claim the damage occured. I also would have felt it. Since I babied the car and only have 3,500 miles on it, I have lots of questions. Got my insurance company involved and now it looks like my car will be totaled as they want $58,000 to fix the battery pack. Supposedly, that doesn't include any work like lowering and lifting the battery and replacement of the HVBJB. I'm attaching the pictures they sent me and the repair quote. The estimator from USAA (my insurance company) is going to look at the car on Monday. My GT has been setting all apart at the dealership for 3 weeks now.

Anyone have any ideas or input? I've never had a car totaled before.

All I know is maybe I need to take a pic of my undersides before I have tow! No way that could happen without you knowing if you were the one driving!

If I were you I would make my own post for this

Yeah that's bad. You (or somebody driving your car) hit something at high speed, I guess you didn't notice. The damage pattern looks like you were bouncing over it (suspension compressed while you were on top of the object). You did hit hard enough to bend one of the cell modules.

I disagree with the quote. I reviewed the service manual battery damage guidelines, you need a new battery case, not a new battery. One cell module got bent, so that one will have to be replaced. The rest of existing modules can be transferred over.

Tell them to take the $38k battery off the quote (why would they put a whole new battery on there at the same time as a case?) add a cooling plate, and reduce the labor down to about 15 hours (~$2500) and then it will be realistic. So the quote should be about $15k.

But if they're willing to total it, up to you. The person that made that quote was not very knowledgeable about battery repair.
