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

[Fixbear]

I think that ship has sailed. Ford will never deliver on that promise

My oct 20 build has the frunk button.

It isn't a five second limit.


?

Man you better watch yourself, them fighting words around here. I once told fokes to stay on topic, I barely made it out alive, JK.

I actually don't think the timeline necessarily precludes the theory. Ford must have known that the contactors were near the limits of acceptable, though they presumably didn't anticipate just how shitty they would end up actually being. Those on-the-edge contactor specs could very well have contributed to the 5-second limit.

The announcement to modify the 5-second limit could very well have been with full knowledge that the recall was coming (or perhaps even an attempt to try to force others at Ford to agree that the recall had to happen).

I have no inside info on this, but my guess is that those of us who have had our HVBJB replaced since May of last year will ultimately be told that our recall will consist of whatever the new PCM, BECM, and SOBDMC software update is that is mentioned in the recall advance notice.

What's interesting is that no one has talked about what the revised software might be. I'm wondering if it might be what actually changes the 5-second limit...

If they knew the HVJB was the weak link, they would have done something then and we never would have had a recall.

They also would have done something on the other models too.

Instead only the Gt got limits.

That and the limit and the contactors welding shut or open also seem unrelated.

Of the hundreds of cases posted on the forum, haven’t heard a single one where someone welded the contactors during a wide open throttle event.

So again, seems totally unrelated.

Looking up the recall today on Ford's website and I noticed the text seems to have changed. It now states:

Recall incomplete, remedy not yet available.

and under the remedy section it says:

Ford Motor Company is working closely with its suppliers to produce parts for this repair. When parts become available, Ford Motor Company will notify you via mail to schedule a service appointment with your dealer for repairs to be completed free of charge parts and labor.

Assuming they are already low on parts for this.

This is all speculation on my part.

Knowing that the HVBJB was a weak link isn’t the same as knowing it will fail at the rates it did.

Remember the Pinto? Clearly and (thankfully!) what we’re dealing with isn’t life and death. In fact the Mach E appears to be stellar on that front. But the same kinds of valuations come into play: what is the anticipated failure rate vs. the cost of a more expensive part.

But like I said, this is all speculation in my part.

Quite sure they do not have 30,000 HVBJB available. Especially if they are remanufacturing them. I think the recall may be a fairly slow process.

We seem to be placing all the focus on the Contactor unit. But they also mentioned replacing more modules. Could this be the missing link?

Not replacing other modules. Software updates.

...and this probably is not a good time for any of our HVBJB's to give up the ghost.

It is a USA specific recall. I expect they will also provide the same recall to the EU, but they probably have to follow EU recall regulations, which are much different from those here. Government regulations make everything harder than it needs to be.

Unless your son is frequently traveling at high speeds, I doubt his car is a high risk for failure. From data collected here, the most common cause is 90+ mph driving, especially 80+ going up a long incline. If he rarely exceeds 100 km/h, the risk is low IMO.

Mark, does outdoor ambient temp play into this at all?

How could you tell if it was a weld event?

Nobody but Ford knows. I suspect it has a minor impact if any.

We drive in the 70s. Ours failed while we were doing 75 or so. Never have driven 80+ up a long incline that I can recall.

Not good. It is better when there is a consistent cause.

It is true, though, that the data shows high speed driving is the most common cause. Not the only cause, but it certainly increases the chances of failure. Unless Ford knows 100% will fail eventually, in which case all high-speed driving does is make it happen earlier.

On a side note, you really need to drive faster. It is fun. Driving slow is boring.

Car won’t start, will need a tow.

They did? Where did they mention that?
