😭😭😭 POST BATTERY CONTACTOR RECALL -- FIRST JUNCTION BOX FAILURE 😭😭😭😭

[Shayne]

Until Ford figures it out I’m taking the following actions:

1. No DC fast charge. I’m either charging at home (level 2) or if I have to charge at a public station I’m using a Chargepoint fast charge (50-60kwH max).

2. No full throttle accelerations.

3. I am not charging to 100%. Keeping it in the 85-90% range.

You want to do exactly the opposite so you can smoke the contact and then you can get a properly designed part installed. If you are close to home have the software recall that gives you notice and the ability to drive it to your dealers it is not anything to really worry about.

Exactly my quandry. If there was a Macan EV today I would dump my MME at the taco stand right now and go and find one.

i4 m50
pro fast and good performance, better charging performance, much better interior quality
con frekin expensive, small inside with ICE packaging, what a butter nose ... I just don't know if I can do that

I5 / EV6 / G60
pro great charging, interesting design on all of them, the Ioniq 5 is as iconic as the MME in my mind in terms of design
cons smaller than the MME, so-so interior quality other than GV60, not as fast and understeery, dubious ADM

But bottom line, I have to have basic reliability in my car, and a company with a less short-sighted attitude towards its customers that does better basic engineering.

I'm actually thinking the Ioniq 5 N or EV6 GT might check all of my boxes, but it'll be a couple of months before I can dial for one of those. Just gotta keep my MME on double-secret probation and hope it doesn't fail with the new part before I can find something I like.

+1 macan EV - can't wait for that one!

There’s still 0 forum reported SR RWD failures. Not saying it can’t happen but anecdotal data is saying there’s no/low risk for SR RWD.

Makes sense. The eTransit isn't listed in the recall as an affected vehicle and it has the same parts as the SR RWD.

Below is a list of the things I am doing differently while I wait for the recall to be applied.

Hey, when we recieve the nortification should we immiddiately take the car to the dealer or in couple of hours/days, any idea?

None of us know.

Can you imagine when those police MME GTs start having this problem?

I was just thinking about the nypd cars… oops SSN, so then criminal gets away

Are you familiar with the new NYPD? The criminal always gets away!

So as far as i understood, if we get the error message we need to take the car to the dealer. Do we need to drive to dealer immediately or in couple of hours any idea?

I would not screw around if you get the UI detailed on the first post in this thread.

DO NOT TURN OFF YOUR CAR.

Go directly to your dealer.

If you turn off your car -- or ignore the wrench -- there is some (unknown to us) risk having your car not restart. Ford isn't transparent on what it is triggering on to warn us, and how much margin they are giving, etc etc. This would be lovely for them to tell us this, but I'm not exactly sure they've thought about any of this for owners.

One more note here -- I believe "Service Vehicle Soon" is a message used for other conditions (just like the more serious "Stop Safely Now" messge) so I think anyone on this forum should be investing in an OBD-II reader and the Car Scanner app to get more precise understanding if these messages are for your contactors or some other issue.

If I had to guess at Ford's unsophisticated UI, they tend to have two levels of powertrain issues, you can sorta drive it but something seriously is wrong ("Service Vehicle Soon") and you are screwed ("Stop Safely Now").

In it's infinite wisdom Ford has no further information it gives a driver telling them what these messages mean really and what they need to do.

This would be fine if this was very rare but trust me, this cannot be so rare as they expected.

This is why I believe it is important for us as owners of these cars to get a code reader so you can understand at least what is going on with the car since Ford isn't telling you anything too useful.

If I didn't have a code reader with me, and if my car did not have a power gauge ( only gt cars officially have it) I would be hard pressed as a normal car driver to know anything about what was happening any what I needed to do to avoid a catestrophic failure of the car requiring a tow.

This is another fundamental failing of ford's thinking and philosophy for the UI of this recall software and the car.

Ford has figured it out and the recall software is their only solution for us.

Do you think this is fundamentally acceptable to have a car that you cannot trust for normal usage as the product was represented to you?

If not we have to be vocal about how completely unacceptable this situation is. I was not driving like Carlos Sainz at Silverstone, and this is absolutely unacceptable that the car exhibits this amount of unreliability.

Well said @scoopman! Eager to know when you are getting the new HVBJB and how this presumably the "permanent fix" will do?

 

[strangeengine]

From what I understand the pack is similar in all trims (some have less cells). That was just the GT boys thinking they are special and better with their right foot than others. It is inherent in the design of the contactors regardless of trim. With yours failing it just shows how bad the design flaw is.

No. The GTs pull a lot more amperage through the contactors, so they are more likely to see the issue.

There are plenty of current numbers scattered through this thread.

You can schedule the update at any time, no need to wait for "the letter" Ford is aware of this and I scheduled mine the same time my MME is getting a window and trim replaced this coming Thursday. the service writer even said this particular update could be done on Saturdays since its a fast install, about a half hour or so.

I am willing to bet the design flaw is related to reusing the same part for select/premium on the GT, not thinking the actual differences between enough warranted a more robust HVBJB. Now fast forward a year and they notice that the part falls too close to the maximum tolerances for select and premium, and behind for the GT's hence why in certain cases especially for the GT's they fail. All cars are affected but ony some will ever have a failure, gt's making having the higher percentage

Hey Tony, thanks for your reply.

I was referring to the notification(service immidiately) in case of battery failure even after the software update.

But apparently it should be taken to dealer asap
