Updates on the HVBJB (22S41)

[Regulus7]

Update on my HVBJB repair. So big surprise is that my little dealership was able to install the new HVBJB in the first week they had it. Bad news is I can’t get my car because of some “small clip” that broke and they cannot find a replacement. So now going on week 2 with no visibility given the “can’t find small clip anywhere and it’s out of stock”.

Sorry to hear that. The HVBJB just came in today for mine and they said they would have it done today. Finger crossed they don’t beak a clip.

There has to be a salvaged mach e somewhere with a donor 'clip'.

This is exactly the type of issue that the dealer system is supposed to excel at. Every dealer should be getting overnight deliveries from the parts distribution system every day. Warranty repair parts should be sourced from the production stock if needed.

Disappointing.

It is surprising that Ford was able to convince the NTSB that a recall with component replacement wasn't necessary. I can understand the Ford financial motivation, i.e. they now get to spread the recall/warranty failure cost of several million dollars over 8 years instead of having a recall and getting hit with the cost in 1 to 2 years. They had to do software anyway so that was a sunk cost.

For us Mache owners it just means we are driving a "grenade with the pin pulled" that could go off at anytime. Yes the software update will give you a little advance notice but the failure risk is still there, waiting . . . . ( This software fix is tantamount to putting a buzzer on a grenade, to tell you the pin is pulled. I would prefer to disarm the grenade so I don't have to worry about it. )

PS: I am curious, when the HVBJ over heats, what is the chain of failure events? It is totally understandable that if the contactor starts getting hot, software can detect that and warn the driver. Then you go to the dealer, maybe wait a few days for repairs. But if the contactor welds closed, it would seem you are screwed. i.e. car needs to be towed, the driver needs to be transported/inconvenienced, a trip ruined and you still get to wait a few days for repairs. ( I very much doubt if very many dealers are going to stock the parts needed for the repair. I can imagine that sometimes they just replace the contactors and other times, with serious over heating, other components will need to be replaced too. So just about every failure will require an expedited parts order.)

Does anyone out there understand how this circuity works? ?

Check out John Kelly’s Weber State Automotive You Tube videos. I believe he has done a tear down of the Mach-E electrical system including the HVJB.

My man. Tesla sends vehicles out to this day with:

1. Steering wheels that fall off
2. Mismatched summer/all-season tires
3. Brake calipers……….minus the pads
4. Auto pilot with phantom braking issues that scare drivers shitless.

Next level shit.

and when i returned my M3 lease i realized they had not installed the two rear rail bolts for the passenger seat. thank god we never wrecked the thing and the passenger seat turned into an ejection seat.

@Fixbear are you saying that the “new replacement” HVBJB are basically the same part except for some minor capacitor or resistor timing changes?

And better control of source quality.

Sorry, I should have been clearer. I have the update or patch. Wondering if they are actually working towards a fix here?

Thank you both for the prompt reply here!

If the connector ends up failing you would be in Ford Service for them to repair it.

Can someone point me to the thread that contains actual measured data demonstrating the Mach E GT has no reduction in initial acceleration after the 22S41 software recall? I can't find it with the search function. I have an April 2022 build date GT (non-PE), and it sure feels like the acceleration (within the 5 sec limit) is significantly muted from the stunning, brutal acceleration I experienced before my car received that software update last summer. I am still on my original (defective) HVBJB.

It could just be that your battery is cold, that makes a big difference if you're going for max acceleration. Set a departure time and then precondition to a nearby DC charger for 30 mins while unplugged to get it fully warmed up.

Update on my HVBJB replacement. Took it in on Thursday and was diagnosed as HVBJB. Part was scheduled for the next morning, Friday. Did not arrive. I went back in and asked for a rental car. They asked me to come back Saturday morning to pick up rental.

Saturday morning I got a 2021 MME GTPE. (Btw ride and acceleration is better than my GT. No surprise. However, it seemed like the recovery from the “5 second” time out was much faster. No scientific proof just my feeling). I was told part would be in Monday and they would have it done then.

Received a call yesterday/Monday at about 3:30pm and was told my car was ready. Returned rental and got my car. All seems well.
Very happy with the whole process.

 

[ryano7700]

Oh yeah. And before they started I asked for the old part number they replaced. When I picked up my car the advisor told me he couldn’t get it.

We're on the third version of the HVBJB now?
