And maybe new shoes to walk home?

Wanted to post this because this forum allways has been of great help to explain my garage what’s wrong with my car ?

Today I’m going to pick up my 2021 Mach-E extended range, after the 7th time of replacing the hvjb. The “old” hvjb replacement parts broke down after a few months. Then the recall came in where ford said it wouldn’t break anymore. There thing is: this part keeps breaking after a week of regular driving, sometimes in a traffic stop.
Conclusion: The old part, for my car, was more capable than the new “indestructible” part

This time they replaced a whole wiring harness in the battery package including a new hvjb.

I’ll keep you updated. I’ll find out soon enough if this was the final fix ( if I manage to drive longer than a week would be a positive outcome).

How is it failing? Is the 12V battery dying with no boot or is the power reduced with error messages but it still drives? Is it hot cold does not matter? Your commute and speed? @heisnuts were all push it it till it burns.

Yours is not a lemon just an extended version of what everyone else got. At your point you would think they may need to explore alternate causes. We would assume your dealer forwards all paperwork to Ford. I think you should contact someone at Ford direct. Combine you PDF invoices and talk to Ford is my advise. Get it elevated to someone that cares and talks sense.

Maybe Ford is dumping all A revision HVJB's in Netherlands? Maybe heisnuts has nothing on banol

I'm still on the fence about buying (in Europe) a used Mach-E precisely because of this.

I can tell you a story about a friend of mine with a different car brand - he had the extended warranty but they quoted him a few hundred for replacing the SOS call battery. Some back-and-forth between dealers, services and other people, he got tired and looked up the highest-ranked name he could find and wrote an email to him (maybe Sales Director for Europe or even higher). It got solved the next day.

Little bit dependent on your tolerance for new tech. It is not a world falling event having the HVJB replaced it is an inconvenience. It has been a training exercise for service departments and most know the process by now.

Nothing is perfect but if it does what you need it to do it is normally good enough. The MME had a problem with the design of their HVJB. The time and path of fixing it was a bit long and not as admirable as I would have hoped. I have not heard of many falling lately but still a few. On your 8th and lucky 7 was not lucky is pretty wild and I have not heard of that many before. Will be interesting to hear exactly how they all failed. Something can be leant.

Mine is doing what it should at this point (cross fingers) working as expected. Cold weather beta tester here. 4 years yesterday and it is still going. Working OK and it is still quick and cheap on fuel. Like the tech but it is still pretty early for some companies/people. Can you imagine them in 50 years. Future looks quick and computer based.

@someone22 : I think that will be my last attempt of solving this myself. Meanwhile I’ll gather data for my lawyer. That’s a challenge in itself cuz the garage says it’s Ford policy not to send information about what has been done to the car allready. Thanks for your advice!

@Shayne its the reduced power with error messages. Hot or cold doesn’t matter, it’s totally random. When commuting at low speed and sometimes at regular speed, once at a traffic stop simply pulling up. Just received another bill for 30 days use of the loaner. The fix didn’t take 30 days, the mechanic went on training and the parts weren’t there. Reading your post your car got fixed permanently and you are driving happy for over 4 years. I think you would call your car a lemon as well after driving around for almost 2 years with the power of an rwd instead of an awd

I was the first Feb 2021 with the contact stuck open killing the 12V battery. No one knew what was going on and peoples cars sat at the dealers for months with dead 12V's. I hooked mine up to a 12V charger and it worked for a year here at home. Was good to go as long as I kept the 12V on a charger. That was fixed with another A revision HVJB at 14 months and then I had the while driving stuck closed contact that was fixed in a week. I drove it also with the second until they had the parts took a couple of days in the shop. I did not feel a huge reduction of power but there was some. Here is to hoping you get this figured out as something is just not right. As noted gather the invoices and start phoning/emailing ford. A couple of times is an inconvenience 7 times becomes a real PITA.

@Mike G could this be false positives like you got once? Sounds very weird being on the 8th HVJB failing as you drive it around slow?

 

[Mike G]

Without being able to take a look at the errors and history it's hard to say what's going on vs. what the tech thinks is going on. I would hope at this point that the shop has called in the Field Service Engineer at a minimum. It sounds like that should have been done a long time ago.

Update: my wife drove the car once commuting and myself twice. This time I drove it in untamed to test the fix. We drove 300km in total and again the reduced power with error messages.

when they just replaced the wiring harness At the dealer I got an error message in FordPass app at 21:48 ( I don’t expect the mechanic to be working at that time, so I concluded the car was standing still) I had the following error message in FordPass app:

Electric system had a power surge, a possible cause is the use of aftermarket components”

at the same time it gave a message to charge the 12V battery but that message dissapeared?!? Anyone ever had a message in FordPass app dissapearing?

The garage is telling me that after the last ota that took place over there the car is giving error:
TRM module “U2100 previous configuration not completed

 

[Amer Kh.]

OMG!!! So, what I'm gonna do if I lose it that day??? I am the only one who has MME GT 23 in the whole of my city and I guess it's the 10th maybe in all of my country ...

Your heartbreaking tale of MME woe made me tear up a little. Fingers crossed for a fair resolution for you.

Mine still rebroke (code) after the 8th service. Given them more pressure to fix it permanently, I received more information.

It seem that this time, they only reset the becm counter and the odb2 code. They have done the usual road test and code hasn't reappear.

They talked 2 to teck line and leave my case open.

Anyway, the trouble will reappear in less then 2 week, like usual. If if goes longer, I would like said that is fix. But going this trend, I waiting for a good engineer for fix it.

They try to evaluate my car to offer me incentives to switch. I just want my car to works when I bought it (used) and will not trust the same model even newer.

@EvPower2k11 im really sorry to hear that you are in exactly the same boat as i am.
Let me give you a update on my Donkey Mach-E:

As advised on this forum, I asked my garage to give a full history of what has been done.They won’t go as far as part numbers but I was lucky enough to receive an email with just the recalls and warranty claims i had.
That alone was an extensive list.

with that list i used LinkedIn and got a free premium trial so you can send messages to people that you don’t have in connections. Then I looked up one of the top persons at ford in my country and i sent him a long message with the list my garage provided. Also said i would put my lawyer on it ( he actually is) en was hestitating to post my story on socials.. of course he didn’t reply but i have a feeling it helped

i also approached my garage telling them it was time to reach out to ford netherlands for a field engineer.tip: tell them your lawyer is on it, you don’t want to sue them cuz they been helpful and probably sick of it as well, but ford “inset your country here” tells you that you need to go to your garage for legal claims. It will speed up things i

status: ford US is writing proprietary software for my car now, and they are going to replace some other cable. One or more of the steps I took worked ? I’m not satisfied yet, for that I want them to tell me they knew what was wrong with the car, what the piece of software is going to to do, and hopefully drive for longer then a week.

all of these steps were advised in this thread so big shout out to everyone who gave advice on how to approach this problem.

anyways, now that they are actually fixing things and more important, other things than they allready tried, I’m starting to get hope.

@EvPower2k11 : I’ll dm you with my vin once they completed the fix so you can refer to it and demand an equal fix

So there is some (little) progress. When I worked in automotive, for an OEM media system, one customer had an unusual complaint about his system, but it was pretty severe. Not sure how much I can go into details, but he had to get out of the car and let the battery drain (I think) or take out the battery terminal and place it again. I was pretty new to that project but a lot of people were involved to get to the bottom of it. It ended up being a very obscure bug that only space-like testing would have brought up - a PLL setting got corrupted. It only occurred one time over many years and millions of products.
At least you seem to have a repeatable problem, so it might be easier for them to figure out. And there are at least two of you.
