Someone lost their THIRD HVBJB

[Mache_Nor]

I know, Reddit - the place of less than happy people, yet - third one has now crapped out. Fourth is the charm…maybe?

https://www.reddit.com/r/MachE/s/bJW0NEj0Tn

Also, the most worrisome sentence is this:
“Yes. The recall involves replacing the HVBJB with a reengineered part, which I supposedly already got back at the beginning of October.”

Thus, me, which also are on my third HVBJB (last changed November 2023) and you lot, seems to be in for a ride.

There have been very few failures of latest HVBJB. I wish it was zero. I still believe, at least to myself, that there are some question as to whether the HVBJB failed multiple times or perhaps service departments did not know what they were doing. There was an issue for sure where codes or a counter were not being cleared and it made it appear that another failure occurred when it may not have. I am not saying it is not true that a Mach actually had 3 failures just that it is much more rare that the newer version fails at all much less multiple times. Not to mention in almost 100% of cases it does not fail but throws the SVS and throttles power so the car can still be driven to the dealer. Only time will tell how this recall turns out. The forum is only a small subset of owners but there does appear to be very few reports of the dreaded SVS these days.

Fair points and I agree with you on this (and I am probably biased due to my third HVBJB myself). As you say a forum is a vocal minority of people, however, are there some way to get a better dataset of the actual failure rate? I would suspect a lot of people do not have problems, and at same time there likely are people that has problems but that does not voice it on a forum, like those of higher age that are not so traversed in the digital domain.

Hey I am one of those higher aged individuals! What I was referring to was there used to be quite a few HVBJB fairure posts on a regular basis on the forum. Those have not come to a halt but they have slowed down. It will be interesting to see what gets reported moving forward; however, there are way more owners than forum members so just because we do not see much here does not mean there are not failures.

Okay. There is a recall. They can take it up with Ford. They obviously didn’t get the new part last time. Bad luck. Sucks.

How are we sure they did not get new part? Is it possible that the technician lied / was fooled - maybe, but to dismiss it entirely seems a bit overconfident.

I wish ford would be more transparent with the data. The dealership we purchased our car from is a network. When we purchased ours last May, they had sold almost 3,000 Mach-Es. Of course they might not be telling me the truth, but they had replaced 6 at that time. All came from extended range batteries, they said most were GT’s. This was the old part.

Oh and just for clarity, that dealership location had not replaced any at that time.

Two originals have failed on me, still testing the third (new version) and so far is working fine. Happens again we deal with it again. Not losing any sleep over things that can not be changed. Driving it just like I did for the first two and so far OK.

This is an interesting comment from the don't read it site, speculation or fact?

You didn’t get the new part. For the new recall, the HVBJB has a new part number that has never been used. You do NOT have the new part. The new part only became available about 2 weeks ago. Loads more detail over at macheforums.

Can someone point me to where on this forum it confirms the second one I had installed in Sept. 2023 is different than the one that is being used for the recall? If it is different than the deadline of built before may 2022 should not be correct and all cars up to two weeks ago should be recalled?

Then they left the ones before May 2022 having to deal with the problems for awhile until they were pushed to fix it.

The consensus in this thread (https://www.macheforum.com/site/thr...replacement-powertrain-software-update.32557/) is that this is a new, 3rd version of the part.

In particular (on page 5)
"Agreed.

According to the recall notice in the OP, only the "V1" (or the "A" part for the GT) is getting recalled. But if you happened to get the V2 part, and it fails, at least you know you will then get the V3 part.

Most dealers have done a few of these by now, so if you get a failure, it will likely get fixed quickly. Back at the beginning the repair time was horrible."

So yea, for GTs if you had the B part, that was V2 and that will close the recall; however the new part number is C.

Yes I agree, all cars should be recalled but Ford didn't because the NHSTA only looked at the original software recall which was only up to May 2022. Essentially Ford wasn't forced to so they didn't. I wouldn't be surprised to see the recall expanded to all cars after these cars get their recalls done.

Sorry for the triple post, but as I said earlier and the Redditor has said...the recall is a new part. The people that have a "C" that has failed is a totally different part than the GT "C", which is new. Super confusing, but it is what it is.

We hope the new C is a totally different part but the part number is exactly the same as the C before the recall was issued. I don’t believe we’ve had any confirmation it is truly a different C part than what has already had failures.

The failures generally happen when it is hotter. We will probably see them start happening after winter again.

It is not the same part number as before. This post shows the part numbers from November to the recall.

There was no C part for GTs prior to the recall. The old C part you are referring to is for Premiums and has a part number of NK4Z-10C666-C. The new recall part number for Premiums is NK4Z-10C666-E.

For the GTs, there was never a C part. And the old Premium C part IS NOT the same as the new GT C part. The new GT C part is LK9Z-10C666-C. Notice the first half of the Premium and GT (NK4Z vs LK9Z).

Side note, I just realized the part numbers end in 666, coincidence?
