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

[mikeinet]

So....no road trips or spirited driving?

exactly...?

I've got a road trip tomorrow and was planning to DC... per trip planning id get home with like 6% battery left... but I don't particularly like that closeness to zero so was going to stop for a quick juice stop... but maybe now its not worth it (I've only done DC like twice on the car)

Well I can tell you that even if your car arrives at the dealership, if this recall is announced nobody is getting their car until the fix is applied, but I'm guessing you know that.

The other thing is that it will apply to roughly half of the cars produced so far. I'm willing to be it's all the ER cars and none of the SR cars, but I could be wrong there.


EDIT: And this just in...Whomp, there it is!

Why do you think it's only ER cars?

You're assuming people are going to look into this like that lol. You're just wrong right off the bat, they'll take their car in, dealer will say just software and they'll go on their way. Plenty of recalls say "dealer will inspect blah blah and based off that will do XX." Engine recall, dealer check for leaking oil, if none, do this to prevent it from leaking. People don't then go, wait, I still want my entire engine rebuilt, that's bullocks!

You're also speculating way too much and constantly saying you know they're related, then you aren't sure, then blah, blah. Saying you KNOW and then saying they're just scenarios is making everything so convoluted.

Well, I apologize if that's how it came across. I'm definitely speculating, since I'm talking about human behavior, like a million of the posts here. What I said that is known is because it's confirmed by Ford. I hope you are right about people's perceptions and reactions.
Let's scrap it and move on. None of this affects me, since my car is not built yet.

it makes more sense it may be more applicable to ER cars... but we've documented numerous SRs that have had the failure already in the tracking thread

Lol, are you kidding me? I don't even have a GT. I'm still waiting for my car to be built (Premium AWD ER). I have zero emotions about this and I'm playing out scenarios because, you know, that's what we do here.
I don't think my speculation is baseless, since we know:
1- There is a new part, with a new part number for new and fixed cars (at dealers)
2- We are hearing Ford execs saying this will be a software update type of a recall for many of the cars

So, doing 2 without doing 1 will make some people think their cars are not really fixed. Because if it's only a software update, why bother with developing a new part? Unless it's determined that SR and RWD are not prone to this issue.

I see. So the scenario that a software issue causes the hardware to do something that damages it is too obscure for you? It's not possible that the inspections are to see if that happened, and if it did then the hardware gets replaced? If it didn't occur then everything is fine and the hardware replacement isn't necessary?

You're deciding what is true in a vacuum with no information other than your imagination.

Appreciate the update, Breeves002. Thanks. I'm calling my dealer now.

Uh, I don’t think we know this at all?

Yes, we do. Under section " Revised Part numbers". It's active since the beginning of the month. https://www.macheforum.com/site/thr...ers-biggest-fear-facts-and-info-thread.18143/

And more here: https://www.macheforum.com/site/thr...cts-and-info-thread.18143/page-19#post-435115

One guy here in Norway got this error last week and they replaced the junction box.

Hopefully the software "fix" is a temporary measure by reducing power while waiting for the replacement part.

Well It may be more than that, but the reports that it's roughly 50% of the cars that have been produced tells me there has to be some discriminator, right? If we were to assume that all GTs were affected due to their performance oriented software settings, and the fact that they all use the same battery pack that the ER uses...can we then surmise or speculate that this affects all AWD ER cars regardless of trim level?

It's got to be something if it affects half the "installed base". So maybe RWD SRs are totally safe from this. I don't know, I'm just trying to sort out which half of the total number of produced cars it would apply to.

True, with SR models, the power output would be less and therefore less heat.
Hopefully my SR AWD is unaffected :S

To be clear: if the problem occurs, the only fix is to replace the HVBJB. Which it doesn't mean it's the new one. Like most cars "fixed" to date, if not all, they got the same part and it can fail again (and it has, in multiple occasions. one guy here had this happen 3 times).
For the cars that didn't have a problem so far, maybe the software update it's all is needed. But there is a new part number moving forward, this has been confirmed.

Now we have to wait for more details. Execs coming out saying "It will be all fixed with a software update" feels like expectation management, but I hope I'm wrong.
