😭😭😭 POST BATTERY CONTACTOR RECALL -- FIRST JUNCTION BOX FAILURE 😭😭😭😭

[Aggie PT]

Sorry to hear this happened to you and the software didn't fix this issue. I am awaiting my Premium SR RWD and having second thoughts on taking delivery with all of these issues.

Do you all know if the newly built vehicles after the recall date have an updated HVBJB that won't fail like these are?

Thanks.

I don't think we should applaud the software "fix" at all. I think we should all stand up against it and demand that we get new HVBJB's. So for some people, maybe the software gives them a false sense of hope that their HVBJB is more protected, or maybe they like the idea that they can drive to a dealer. Not for me.

Agreed! Shhh.. probably better to just give the really affected cars brand spanking new 23' GT/PEs

New cars should have the new part.

Pretty clear why you chose the taco stand dealership ...

Too soon? Apologies that my Photoshop skills are not to @DevSecOps standards.

OMG LMFAO

Argh! So sorry this happened to you @scoopman but glad that you are safe and making the best of the situation. I didn't see in the posts here (sorry if I missed it) but once you got to the dealer did you try and turn the car off and see if it would turn back on, or did you not want to chance that? Limp mode probably kept it from welding right?

I did not turn it off -- once it was in the service lane it was their problem.

Oh one more thing which worked out very well and I am so glad I did: I hid one of my set of keys in a faraday bag zip-tied under my plastic pieces in the hood. This was very important since I normally only use PAAK and did so on this trip.

But I took out my "oh CRAP!!!" set of keys from its hidden location to give to the dealership.

EVERYONE who uses PAAK should do this.

You get the Photoshop credit on this one. But I deserve a little credit for the idea....

I think this failure was obviously, in part, due to the Five Second Control Module not being updated. They are still working on that OTA.

Todd, the only way Ford will do this is if a lot of people use lawyers, the auto media catches on to Ford's initial failure and attempt at a coverup and eventually the stock gets the crap beat out of it and heads roll.

It's far too easy to put software that kneecaps the power and call it a fix. Somebody will likely get a bonus for saving the company money for doing that. This has to get a lot worse before they will make a real fix.

I bet this will get a lot worse -- I took it easy before the recall and my second junction box fried itself in 1700 miles!

And just like that BOOM new profile avatar!

Which means it's not a fix as I've said for months. It's still an underdesigned part and should be replaced.

As I said the part failed less catestrophically this time, and in that way probably satisfies the NHTSA safety concerns.

But it does little to impress me as Ford standing behind the engineering and basic reliability I expect in a $70,000 vehicle.

Oh boy. Sorry this happened. I think the odds @DevSecOps is correct about the recall just went to high (at least for the moment). The general thinking here on the forums seems to have been the software update would prevent the welding from occurring (at all). If there wasn’t something else wrong with your car @scoopman, it appears the software is designed to prevent welding from completing allowing the car to limp off road perhaps. Or that the issue with your car was sufficiently severe to jump straight to limp mode. Either way points to a worse part problem than I’d personally envisioned. There are worse places along I-5 in the Grapevine and Tehachapi’s for this to happen, but no place is good.

Ford should be motivated to get people on this quickly. Perhaps some answers will be forthcoming. Oh and update the NTHSA with the news jerboas. Low priority that.

Anyone have an idea as to what percentage of HVJB weld jobs are GT-PE’s, GTs, AWD ER, AWD SR etc?

I think we only have the poll from our forum, but that is enormously flawed as a data tool. Ford knows this of course, but I would doubt this would be revealed to us. Logic would tell us that GT / GTPE will have more incidents of this as they have a ton more voltage and thermals affecting the contactors and their surrounding packaging than non-GTs.

Makes sense. I’m just engaging in some idle mental speculation atm is all.

Scoop obviously has his opinion on this and it's valid. My comment on the other thread is because people think that this is a "fix". The thread title by Mach-Lee even says "fix". It's not a "fix" and people are rushing to the dealer over a 0.5% chance of failure to "fix" something that's not "fixable" with software.

Personally, I would rather it just fail on me when I'm stopped somewhere. The anxiety for me, and I'm a calm person, of it happening while driving would be much greater than "oh my car won't start". I would also be pissed that I have to drive under the limit with flashers on if I was on a freeway somewhere. Additionally, there's gonna be a lot of people here on the forum and elsewhere that see this message, stop and TURN OFF the car. That could indeed brick it, so therefore the warning could be far worse because someone could pull over along side the road and then be stranded. Normally, when I park places, it's not along the I5 (10 lane) freeway.

I don't think we should applaud the software "fix" at all. I think we should all stand up against it and demand that we get new HVBJB's. So for some people, maybe the software gives them a false sense of hope that their HVBJB is more protected, or maybe they like the idea that they can drive to a dealer. Not for me.

Sorry if I missed this from one of the other threads, but how do we know a software fix isn’t possible? Was something revealed (unofficially) with a more detailed explanation of how/why the failure is occurring aside from it apparently being a temperature issue?

So the software monitors the HVBJB and alerts if it falls out of parameter. The "fix" for a car that has the DTC's indicating that it's out of parameter is to replace the HVBJB. The software is a way for Ford to say "ok we'll get you somewhere and let you know it's gonna fail, before it actually fails, or even when it has already failed".

It's a way for Ford to comply with the NHTSA probe but save millions by not replacing the defective parts. The part isn't magically better. The software doesn't apply to the part at all since it's not a part that can be updated with software.

The software fix did not work for me at all obviously -- my car bricked with normal usage an owner would engage in with their car barely 2 days after the software recall was applied and 1700 miles since my last junction box replacement.

My charging performance was definitely worse, especially right after I stopped at the charger for a couple of minutes. Also, I definitely saw more power limitation jail bars after leaving a DCFC for several minutes on the highway.

I think the software tries to be much more agressive when it detects thermal-related signals to limit power to let things cool down. But again, this strategy absolutely did not work in the real world for my car.

I want to reiterate that I think this is totally completely unacceptable that Ford is not replacing this under-spec'd part on the GT/GTPE cars with a part that would withstand normal operation of these vehicles.

I have never in my life owned a car that is as unreliable as this car has been, and it's so sad because the car is great ..... until it doesn't work.
