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

[MachE70]

I wish it was an even better part; however, based on what others have shared Ford has now removed from the recall list the VIN numbers of vehicles that have had their HVBJB’s replaced. That tells me there is no “new new” part and that the part that has been being installed since May 25 2022 is what we will receive. Once again basing this on what others have shared. Ford also stated in their fix statement to the NHTSA that the part that will be used in the recall is the part that began being install May 25.

You may well be right, but I hope not. If Ford is not recalling any post-May 2022 new cars, why would they recall any pre-May 2022 cars that have already had their HVBJBs replaced with the same updated part that is in the post-May 2022 cars? It doesn't necessarily mean we are stuck with only the second version of the HVBJB for this new part--Ford and the NHTSA would essentially be saying those updated versions fail at a low enough rate that they can just be replaced as needed on a one-off basis. We will just need to wait and see what the new part #'s are when Ford actually rolls this recall out.

If indeed it is a new part, I would like to know what kind of testing they have done and how robust this new part really is. Like maybe pushing it to the limit in the Mach e Rally version and on the @heisnuts test course??

There is no point in calling the dealers. If your car is part of it, it shows in FordPass and on the NHTSA website.

Where on Ford Pass? The recall shows up on Ford.com but not on my Ford pass.

Yes, that was pointed out earlier. If they're on Ford.com in your account, then why would it matter? But in FordPass, under Vehicle, then Service, then Customer Satisfaction Program, I see them on my truck. Mach-E just had them done, so I have no CSP tab.

My point, based on what others have shared, is Ford has now removed vehicles built prior to May 2022 that have had their HVBJB replaced from the recall list. I am not saying nothing has changed with the HVBJB but I doubt it. I do hope to get a picture of the replacement when it comes in to look up the specs on the contactors. Like anybody I would prefer that the recall gives me a HVBJB with a 0% chance of failure.

Mine's done. Drives fine. Threw 2 error codes in the dealer's parking lot, I knew from before to shut it off, restart, and they didn't reappear.

Part used was NK4Z 10C666 CRM

The fact that the CSP button disappears when there are none to show causes confusion.

Poor software design.

Well, as I noted on another thread, I got the Service Vehicle Soon signal on Monday morning while in the mountains of Western Maryland about 160+ miles from home. Limped home with a lost AWD and pretty much all driver assist features. Even the Reverse Brake Assist.

Driving now without AWD (mine is a March 2022 AWD Extended Battery Premium with 52+k miles on the odo... sole owner) - the car drives but it has lost its nimble sure-footedness. It drives like a pot-bellied pig, is about the best comparison... adequately but without finesse. Just based on how it feels now, I am very glad I had opted for AWD back during purchase, despite the mileage penalty.

I have a Monday A.M. appointment. My dealership is one of the good ones, and the EV tech is also the maintenance shop foreman.

Today, an intermittent Stop Safely Now began to manifest... so far, only during backing up. So now I have an orange wrench (SVS) and the red battery+! (SSN) icons next to each other on the dash.

Good thing this didn't happen back in July when nephew and I were making multiple thunder runs with the Mach E on the Bonneville Salt Flats God does protect the fools ??

As noted elsewhere, the dealership yesterday definitely diagnosed a front drive unit failure (my car is AWD) rather than an HV Battery contactor failure.

I am posting / responding to my former post in this HV Battery Recall thread as a sort of Public Service Announcement because when it does happen, this serious-to-eventually-critical failure, which BTW can happen to either front or rear drive motor, manifests practically just like an up-and-coming HV Battery contactor failure ...although "drive unit" failures have apparently been far, far less prevalent than HV Battery contactor failures. Meaning, when a Mach E gets a SVS or even an SSN and has a significant loss of motive power, it could be either the HV Battery contactors beginning to fail, or a very different internal motor oil pump failing / motor overheating / motor shutting down event which is obviously caused by a very different set of internal circumstances.

The dealership's Tech was getting mentally prepped to drop the HV Battery... but the 28 failure codes guided him over a day's investigations to the failure of my car's front drive unit, which is apparently a major component of the front motor. If the primary cause is / was a failure of the motor's internal oil cooling pump (see URL just below) there's no telling how long I've been driving on a failing motor oil cooling system... no symptoms whatsoever until on a steep mountain pass on I-68, BLAM: the IPS lists loss of the AWD and a bunch of other orange messages and of course the SVS message, and the car loses notable power while moving.

Here is DevSecOps' original thread about this far less likely but similar-appearing failure:
https://www.macheforum.com/site/thr...-soon-facts-and-info-p0c2a-p2796-p2797.27802/

The dealership started a COPIS action with Mother Ford, is giving me a Mother Ford - paid loaner and is projecting (Inshallah...) that the necessary front motor parts will arrive early next week and the car will be fixed by the end of the week.

Of note: the car (I am the original owner) now has 52.5 k miles, and the powertrain warranty is good for 60k miles... so, at this point I am a Happy Cat he hee...

so, this means Dealers are already performing the recall? Do I need to wait for the letter to arrive?

Rick’s failed during a trip. To the best of my knowledge recall work is not yet approved.

Correct. And mine failed before the recall was issued (by days). But, if yours fails, Ford should still replace it before the recall is finalized.

Thank you.

I see they added the VINs to the Ford Recall search engine. You can run your VIN through Ford's website HERE

It seems I have four recalls that I was neither informed or aware of.

The sentence in this latest recall for my '21 Premium AWD ER below was interesting...thankfully, I have only had to use the 220 outlet in my garage

"Until the required part has been installed on your vehicle, Ford recommends avoiding repeated back-to-back wide open pedal accelerations using dc fast charging only when necessary example long trips."

 

[T.S.]

Same here…brought mine in yesterday for the SVS and service manager said he ordered it for arrival in three days.

But...is that going to be the old part that needs to be replaced by the recall?

 

[T.S.]

So Saturday morning I charged 40 minutes at EA in Barstow, ca heading south bound on 15. In number 1 lane in Hesperia, ca lost power
Lucky it was clear to get on the right shoulder. About 10 minutes was able to get it going and got home.
Took it to Chino hills ford, the service advisor says it's a bad fuse box. 21 extended range GT.

This was part of the recall info when you search for your VIN online at Ford...
