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

[Av8tor]

My guess is that when the "New" warning appears, it has not yet "Welded closed". If the contractors, and dare I say, melt Open, then the SSN message appears. Again, my assumption is that warning is the preamble to the event. The reduced power is a failsafe to prevent the weld.

I would bet, the car did start. What we don't know is how far you can push it once the "New" warning appears. That's why folks are recommending, do not pass Go, but right to a dealership that can diagnose/repair it without involving a tow truck.

Leaving the car running is often not an option anyway, depending on where you are at the time of fault, and the time of day/night.

I just had the error in Car and in FordPass App myself -"Powertrain Malfunction/Reduced Power"

The car has continue to work even after stopping and powering it down a couple of times.

Do not have my OBD2 right now so will confirm error codes later tonight

I do not have the recall SW update yet but 2 week ago they did update most modules as I brought the car for another problem with the door -"Door Fault - Service required" and asked them to update the SW as much as possible, not sure if one of those updates helped or even triggered the error as the part is already failing

I had my HVBJB replaced already back in march with the original part number as the updated came later (I think)

Bringing my car to dealership tomorrow and will open case with Ford.

I love my GT but this is becoming a real crippling problem for us.

It sounds like you're doing at least as well - without the recall software - as Scoopman did with the software update.

As you suggest, maybe it's not exactly the same issue. But so far I'm still not clear on what, if any, value the software update has for us.

 

[markboris]

I'd prefer to get a revised HVBJB proactively instead of crossing my fingers that I never hit this issue. Even with the software update.

I'm thinking about doing this also.

When I had the software update done (Recall 22S41) I asked the service manager how much it would cost for them to replace the HVBJB. He said their manual shows 5.5 hours but that was for warranty and Ford usually reduces their actual labor time needed so they might add up to 1.5 hours more making it 7 (it could be less but he was quoting the maximum it would be). At my dealers rate of $175 per hour, that would be $1225 for labor only. The HVBJB part (NK4Z-10C666-C) will cost $736 plus tax. The total repair would be around $2021.

Each month I drive a minimum of 2 times to the airport (that is four, two hour, 117 mile drives) and I DCFC each time at the airport. I also drive at least twice a month to Yosemite and surrounding areas in the park which are at altitudes of 8600 feet. Between January and June I put 10K miles on the car. It is very warm here in the summer, generally 102-112 and several times I get the "plug in vehicle" warning when I shut off the car because it's hot. I'm not light on the go pedal driving on the mountainous roads around here. I don't plan to change where, when and how I drive but I would like the car to be reliable and if Ford doesn't come up with a hardware recall for the HVBJB in the next few months, I will have it replaced and pay for it myself. I love this car for it's all around capabilities and don't want to get any other EV at this time.

That’s a great point and part of why not replacing everyone’s HVBJB seems risky. The issue is more likely to crop up when you are leaning on the car, like happened to Scoopman, on a road trip or something along those lines.

If it was most likely to occur when you are five minutes from home at the grocery store, fine, maybe not such a big deal, not so different from getting a flat on a runflat tire, frankly, in that circumstance if we get this reduced power mode now instead of an immediate shutdown.

But if you are on vacation, trying to catch a flight, far from civilization, this is a big deal failure and Ford needs to either replace for everyone or figure out some kind of stress-test so we don’t find out for the first time we have an issue the day we are driving into the mountains or wherever.

The dealer with my car has part NK4Z-10C666-B sitting there now. I'm just now trying to get them to show some empathy and put it in my car.

Mysterious that there's now a C part.

That's foreshadowing if I've ever seen it.

If they won't, I would try seeing if other local dealers have it, assuming it is portable and you could pick it up, if your alternative is having to ditch your car to go back home if this isn't done right away.

Biggest dealer in LA is Galpin, I think second biggest is Sunrise Ford North Hollywood, I would try those first.

To me the overheating regen issue just shows up Fords piss poor real world testing of the mach-e. No doubt by the time a mach-e model refresh turns up in a few yeas time you would assume it won't suffer from these school boy errors.

The problem for Ford of course if that with all these issues is how many early adaptors have now been put off ever getting a Ford EV again as it doesn't give much faith in the engineering talent when owners are having problems derived from doing the basics of just driving and charging it.

I think you're right that their testing is inadequate, but it is probably not intentional or not a result of cost cutting.

Unlike with ICEs, which have been around for over a hundred years and that they probably know what problem areas to focus on whenever testing a new vehicle, they are just now learning how to deal with EVs, and it seems EVs fail in new and different ways from ICEs.

They probably should give all their new EVs for the next several years super large testing budgets to try and suss all these issues out.

This is great info as a backup plan. This is the reason I asked about the estimated cost earlier in this thread. Thanks for sharing!

This comes up a lot ... I've asked people at Ford to step up and provide the exact information. I will probably have something next week since they have this week off. It appears from unofficial reports that cars which went into production on May 25 and later will be getting the new HVBJB, but that's not 100% confirmed yet.

I know there is information you are unable to share regarding this issue. I am wondering though if Ford knows what is the root of the failure. I realize the part is not robust enough but do they know for sure what action takes the current over the limit? I was wondering if there is any potential for a current surge as the motors switch from drive to regen? It just seems that with a potential second reported issue (may not be HVBJB) to a car that already had a failure that there may be another specific issue causing the contacts to “weld.” Perhaps I am just attacking windmills and this just boils down to a weak HVBJB that is damaged over time.

It'll get done. Dealers do not have these parts on their shelves as far as I know. We just have some other things going on that need to have us get home earlier if possible.

So they won’t prioritize your repair?
