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.

Also guys I wouldn't hold your breath on this removing the 5 second power limit for the GT. I believe there are other limitations of the battery pack causing that.

The build dates say May 27, 2020 through May 24, 2022 ... Do you mean if it was built before may 24th?

I know... Thats exactly what they are saying. They don't say what trims it applies to and if all vehicles need parts, software, or what...but more info to come. This is super preliminary, so just know Ford has acknowledged the problem and will give more info when they have it.

So if we are in the production range we are for sure part of this? Or just specific VINs in those dates? We are pretty much in the dark until a fix and letter comes out huh?

So it seems to imply at the top there will be a software update or the software update is what caused the problem?

It does say: Secondary On-Board Diagnostic Control Module (SOBDMC) and Battery Energy Control Module (BECM) Software Update

Hopefully they are optimistic a software update can solve the problem.

Yep. But your original message said those built after May 24th would have to wait. Did you mean before?

This is my EDUCATED GUESS, not any factual info.

A software update will come to all vehicles to help reduce the issue. Some vehicles will get replacement parts. This is my GUESS. It is possible all vehicles get replacement parts... we'll have to wait and see. There's a ton of unknown so its a wait and see game now.

I do not believe a software update will not solve the problem for GTs, but it may for lesser trims. This is my best guess, not any real facts.
