Safety Recall 22S41 - 2021-2022 Mach E - HVBJB Recall [high voltage battery main contactors may overheat]

[breeves002]

The most distressing part of this whole thing is having to go to the "dealer" for a fix..

Dude literally how I feel. I cannot stand going to Ford service. I've had the hardest time in the past. However I will say this time is different. Not sure if thats because engineers and other corporate guys are breathing down the dealers neck but they've been a lot better than usual. My car has this issue now and is at the dealer being fixed (with the new part I think).

They should just retrofit all the HVJBs with the one from the Lightning ER. Problem solved. There. I said it.

....well it sounds good in theory...

..I think..

Don't you put that evil out there!

I guess I should rephrase. There is a fix but it isn't available yet. Except maybe for vehicles that have actually broken (mine for one). I guess the point is for most people here right now there may as well not be a fix because they can't get it yet. I'm just trying to avoid people bombarding dealers wanting to get the recall done when they can't yet.

I was wondering about that myself.

My GT has had the HVBJB replaced (about a month ago) so do you think our replaced parts did fix something?

Is there a chance we already have fixed parts and only need SW updates?

Since recall was just announced now and it may require parts not available I was thinking the parts are new and updated design, but who knows

 

[Gimme_my_MME]

but who knows

I can assure you that Ford knows. The parts are being very closely tracked so if you don't have the updated part you will be contacted

It is possible but probably the old part. I don't know the answer. You'll have to wait and see.

Is there something unclear in the original post? ALL MACH-Es made until 5/24/22 are included at this point. Looking up your VIN is a total waste of time.

You would need to look at the part number to see if you got the newer part or just the existing problematic one to at least get it moving again and get you on your way.

Mine was built 5/25 (at least according to the tracker) and is listed as included in this database.

And...it's made the news now

https://www.cnbc.com/2022/06/14/for...g-mach-es-due-to-potential-safety-defect.html

Here's my two takeaways from the article:

"Nearly 49,000 of the roughly 100,000 Mach-Es produced during that time frame will be part of a recall, Ford spokesman Said Deep told CNBC."

"(T)he company’s remedy will include a software update to the vehicle’s “Secondary On-Board Diagnostic Control Module and Battery Energy Control Module.” It will be conducted remotely, or over-the-air. Customers also have the option of taking their vehicle to a Ford dealer."

So I'm guessing not all units. Some may only need updated software.

This is true, we don't know how many people are working on this issue, but them saying "Q3" for this fix (or even just more info) instead of narrowing it down to less than 3 whole months isn't confidence inspiring.

Speculation warning: They may not know exactly what is causing this. They might have a good idea of some of the factors in this cause but haven’t been able to identify a part or a software coding error. Or might not know the fix just yet. Or might be looking at a software update as a stopgap measure while they try to find the cause — all of which takes time of course. And as we’ve discussed here as nauseam, the third quarter is “soon.”

My guess is they don’t know if this is a trim wide thing yet, a dual motor thing or every car built. And the post May 24th cars? Let us know if they’re “throttled” in some way either acceleration or in DCFC peaks or some such things (all things talked about on the various HVJB threads).

Honestly, this notice of recall didn’t do the vast majority of us any favors., It just threw doubt onto cars that are and have been running fine, while offering those with real issues no solution at all.

DO NOT CALL YOUR DEALER TO SCHEDULE SERVICE! PARTS ARE NOT AVAILABLE!!!!

At the bottom of this post I have added information to help people understand what is going on.

NOTE: NOT ALL VEHICLES ARE AFFECTED NECESSARILY. VIN lists will be distributed when the time comes. Please be patient. Just know Ford has recognized this problem exists and it is a safety related issue. No action should be done at this time from any Mach E owner.

It's finally here! This is the recall for the HVBJB issues people have been having. Note this is an ADVANCE NOTICE recall meaning no fix is available but Ford has identified a problem! It is safe to continue driving your car in my opinion.

Anyone with an affected VIN that hasn't taken delivery of their car yet...I'm sorry but if it was built before May 24th you won't be able to until at least Q3.

You will be notified in the mail if you have an affected vehicle when parts/software updates are available! Do not call the dealer now!

Bulletin to dealers below:
------------------------
TO: All U.S. Ford and Lincoln Dealers
SUBJECT: NEW VEHICLE DEMONSTRATION / DELIVERY HOLD - Advance Notice - Safety Recall 22S41
Certain 2021-2022 Model Year Mustang Mach-E Vehicles
Secondary On-Board Diagnostic Control Module (SOBDMC) and Battery Energy Control Module (BECM) Software Update

Affected Vehicles: Certain 20201-2022 Mustang Mach E's produced at Cuautitlan between May 27, 2020 and May 24, 2022.

REASON FOR THIS SAFETY RECALL
In the affected vehicles, it is possible that the high voltage battery main contactors may overheat, which can result in an open contactor or welding condition. Should the contactors weld closed while driving, a powertrain malfunction warning light will be illuminated on the next drive cycle, along with a no start condition.
If the contactors open while driving, a powertrain malfunction warning light will be illuminated, the vehicle will display Stop Safely Now in the instrument panel cluster, and the vehicle will experience an immediate loss of motive power. The vehicle will coast to a stop, and all 12V systems including power brakes and steering will remain functional.
SERVICE ACTION
DO NOT DEMONSTRATE OR DELIVER any new in-stock vehicles involved in this safety recall. A complete Dealer Bulletin will be provided to dealers in the 3rd quarter of 2022 when it is anticipated that software and/or parts ordering information and repair instructions will be available to support this safety recall.
IMPORTANT: Dealers should open a Repair Order (RO) only when a full dealer bulletin is published. Opening an RO against an Awareness or Advance Notice will result in warranty rejections against a recall.
CUSTOMER NOTIFICATION
Owners of record will be notified via first-class mail after repair instructions and parts ordering information have been provided to dealers.

----------------------------
Another Note from me: This thread is just to help people become informed. There are NO publicly released FACTS about this issue. Anything is speculation. Please wait for Ford to notify you and release more information.

What we do think we know. NOTE THIS IS NOT OFFICIAL FORD STATEMENTS THIS IS MY PERSONAL OPINION BASED ON INFORMATION I HAVE GATHERED ON THIS FORUM!
What is the HVBJB?
HVBJB is the assembly that has contactors, fuses, and some other electrical components at the front inside of the battery pack. This connects the DCFC to the HVB as well as the rest of the car when it is turned on.

What is the problem?
The HVBJB contactors can get in a stuck open or stuck closed state. From reading failures on the forum I have gathered that MOST failures are the + contactor that powers the whole car welding closed due to excessive heat. If this happens the car will not turn off while driving but will not restart.

Why is this a safety recall?
If the contactor gets stuck open while driving the car will lose its propulsion and 12v battery charging. This could be dangerous. If it gets stuck closed it is unlikely to cause an unsafe condition, but if both the + and - become stuck closed then the battery cannot be isolated which can be dangerous. Therefore the vehicle will not restart if one is stuck closed.

Am I a part of the recall?
We don't know yet. You need to wait for Ford to notify you. There is no reason to look now, though you can find out with Ford chat or running your vin in Ford ETIS. I do not recommend calling your dealer at this time unless your vehicle has a drivability issue. It appears possibly every single Mach E built before May 24, 2022 may be impacted but it is unknown at this time.

What is the fix?
Exact fix for each vehicle is unknown. It appears a new HVBJB part may be required, a software update may be required, or both. We do not know and will not know until Ford releases more information.

What should I do now?
Absolutely nothing. Continue driving your car. The only advice I can give is especially if you have a GT/GT Performance model try to avoid a lot of high speed driving (90MPH+) and try to do your best to be easy on the throttle. Back to back full throttle applications can generate a lot of heat in the battery components including the HVBJB and heat seems to be the largest cause of this failure. Again this is MY OPINION, not any facts given to us from Ford.

When can I expect more information?
Great question! Ford says fix coming Q3...but from what I've gathered its most likely late August at the earliest we will see something. I would expect more information released when the fix is available around then. Patience is a virtue now. I will update this with the latest information as it is released.

Not True about the parts not being available, my MachE Gt Performance was dropped off last week for this issue and the part came in yesterday and will be back on the road wednesday!

 

[RickMachE]

People also need to remember that dates don't define recalls, VINs do. Why? Because the affected component could have been installed / programmed at a much different time than the car's production date. So until they clarify things, no one really knows if they're part of the 49% of produced cars recalled.

If it's truly two modules and software updates, I would expect that it's most of the cars. Then the question is who has contactor damage and who doesn't.
