Recall Information: High Voltage Battery Junction Box (23S56)

[MachE70]

Hi Mustang Mach-E Owners,

Ford Motor Company has issued a recall for Certain 2021-2022 model year Mustang Mach-E extended range and GTs built between May 27, 2020 to May 24, 2022 related to failures of the High Voltage Battery Junction Box (HVBJB).

If your vehicle is included in this recall, you will receive a message from Ford soon with next steps.

In the meantime, you can also verify if your vehicle is included by entering your VIN at www.ford.com/support/recalls/

What is the issue tied to this recall?
Direct Current (“DC”) fast charging and repeated wide open pedal events can cause the high voltage battery main contactors to overheat on certain Mustang Mach-E extended range and GT models. Overheating may lead to deformation of the electrical contact surfaces, which can result in a contactor that is prevented from properly closing or a contactor that welds closed. An overheated contactor that is prevented from properly closing while driving can result in a loss of motive power.

What is the cause of the issue?
The high voltage battery main contactor is not robust to heat generated from multiple DC fast-charge and wide-open pedal events. A prior software update improved monitoring and management of the main contactor. Damage to the extended range and GT contactors caused by wear prior to the software update may reduce the effectiveness of the software.

What is the expected repair?
Once parts are available, owners will be asked to take their vehicle to a Ford dealer to replace the High Voltage Battery Junction Box.

Do I still need the software update related to this recall if I haven’t yet received it?
Yes.

Which vehicles are affected?
Certain 2021-2022 model year Mustang Mach-E extended range and GTs built between May 27, 2020 to May 24, 2022.

Why are Standard Range vehicles not affected?
Standard range contactors are not included because of the difference in heat generated in the contactors. The extended range and GT vehicles will see more current flow through the contactors than the standard range due, in part, to larger battery capacity and higher output electric drive motors.

What are you doing to take care of customers?
We are working through how we will support affected owners, including providing rentals and pick-up and delivery services.

Is there anything a customer can do to reduce the chance of the contactor overheating until their vehicle is repaired?
Until parts are ready, we ask that affected customers limit repeated back-to-back wide open pedal accelerations and use DC Fast Charging only when necessary.

Is there a warning sign that customers should be aware of?
For vehicles that previously received the software update in most cases, the software will proactively detect damage to the contactors and display a warning wrench light. If the contactors weld closed while driving, there will be no immediate effect on vehicle operation. Upon the next key cycle, a wrench light will be illuminated, and vehicle will not start. If the contactors are prevented from properly closing while driving, a wrench light will be illuminated, the vehicle will display “Stop Safely Now” and the vehicle will immediately lose motive power. The vehicle will coast to a stop, and all low voltage systems including power brakes, steering and lights will remain functional.

When will you notify customers of the recall?
We began sending letters to customers on November 3rd. Customers can also verify if their vehicle is included by entering their VIN at www.ford.com/support/recalls/

Will there be a charge to customers?
Customers will not be charged for service.

What is Ford’s reference number for this recall?
The reference number is 23S56.

Can you tell us the part #'s for the new HVBJBs that will be put into the recalled cars? Are they different than the versions that have been used to date as replacements for failed HVBJBs? As I am sure you know, some members of this forum have reported failures of those replacement versions as well.

We also need to factor in the time it takes for the 2,000 dealers to work on 30,000 recalled vehicles in addition to all the work they have to do. I would assume this would be more complicated than stockpiling 30,000 parts.

 

[AKgrampy]

Just got the letter and I’m also selling the MME around year end. If there are parts/service delays, I hope this does not impact my ability to trade it in with a major outstanding recall?

Well what does the letter say? Do you have to still wait for parts or call an make an appointment?

 

[kennethjk]

Considering all the factors I probably won’t even have the car by the time dealers get parts and they have time to install them

best thing that can happen is that it breaks on its own

Oh yea of little faith!

Pretty much a realist and based in on history but yeah you’re right

 

[Kamuelaflyer]

This does not mean there are no parts available. If you have the fault you will still get repaired. A stockpile needs to be built up to support all the other incoming replacements

While the powers that be are building a stockpile of parts, perhaps they could consider building a stockpile of dealers willing to actually do safety recalls on the cars they sell instead of avoiding overriding schedule the work? (Glass recalls, waiting 18 months plus now). I have zero faith that I’ll ever get this recall done.

 

[Kamuelaflyer]

Ford will send a letter when the remedy is available.

So, never then.

Realism. Relying on Ford’s dealers to do anything is a dicey proposition at best.

Not the best track record so not much I can say. The recall did state that they would begin sending letters to owners when the parts became available. That is why I asked the person who said they received a letter already exactly what it said. I do not know what the rules are for recalls but if we have to receive a “new” part I could see this taking some time but if we can receive remanufactured parts as well then there may be quite a few available. And I would imagine Ford could set up a quick turn around for recall change-outs as they occur as my understanding is all they are doing is changing out the contactors for the rebuilt HVBJB’s. (Could be wrong on that) Getting a recall appointment - now that may be an issue!

 

[JohnFoxeSheets]

So this thread has established 1) avoiding repeated WOTs and DCFC charging sessions increases the chance that your HVBJB will survive until parts are available, 2) parts for the recall aren't yet available, 3) if you HVBJB fails before recall parts are available, you can still get it replaced.

So logic would suggest that if you wish to get your HVBJB replaced soon, you should do repeated WOTs and DFCF charging sessions... (Or come to Cali and do the Grapevine a few times.)

Well this should be fun.

My extended family is blessed to have a vehicle we take turns using as a "loaner" when our cars are in the shop. We pass it around like a casserole at a family potluck.

It's the same car I drove after a deer took out my Mustang Coupe, while waiting for my MachE to be built (it was ultimately built a week or so before they started installing the updated part at the factory, wouldn't you know).

I've yet to get a loaner or more than a "discount" on a rental during repairs at my small town dealership, so I'm not holding my breath. But I am putting my request in with the family for a tasty tuna-noodle casserole.

The casserole is in use while my wife's car is in the shop, but we'll hopefully get her car back this week and then I'll make my appointment for the recall.

Meanwhile, I did visit the dealership and saw that they have the battery hoist (with a MachE battery sitting on it), and they tell me with obvious pride that they now have the personnel, tools and training to do the recall. Nice to see since when I bought the car they had none of that stuff.

Well what does the letter say? Do you have to still wait for parts or call an make an appointment?

Wait, I already tried calling proactively and the recall is still preliminary. So until Ford pushes it to a "Real" recall (aka, when they have enough parts available) the Dealers look at the computer and it says "Remedy not available yet".

He most likely received the same letter that I did. (23B50). It's just a Software Update for BCCM. Not related to this recall.

My MachE GT was manufactured May 17 2022 per the window sticker, but Ford is telling me that it Is not included in recall 23S56. Does this make sense? There first reasons for not including my car was because this recall only applies to hybrids. When I said that made no sense, they just said it was VIN specific and mine wasn’t included. Obviously not a confidence inspiring answer.

Man, I hope it doesn't rely on dealers proactively reaching out, I'll never hear from anyone. The one I bought it from is over 2 hours away and they've never contacted me and the one I get serviced I've never had them proactively tell me about a needed recall (though I haven't really been part of one).

I was just recently contacted, by phone, from my purchasing dealer about the battery port CSP, out of the blue. They gave me the option for mobile service which I availed myself of. It was, shockingly, painless and easy and the appointment was only about two weeks out.
