GT PE owner had the failures twice but the HVBJB was never replaced.
The first time the dealer was told to just reset the errorcode (from Ford NL) and gave the car back.
The second time the car did not even move anymore, but after investigation from the dealer, the wiring connected to the HVB was replaced, because they found weird values.

Now i am about 10.000 miles further and nothing has happend since.

I am a 2022 GT March build that got the SSN and HVBJB replaced at around 3,100 miles in August 2022. Won't vote as I see that OP @mkhuffman is focusing on 2021's.
You can vote on #3. It applies to you. If you want of course.

2021 GTPE, 17K miles, no failure- I haven't even seen the "prison bars" in months. Clearly it likes the warmer weather.

Ford Mustang Mach-E 2021 GT/GTPE MMEs Without HVBJB Failure - Tracking List IMG_2758

The very short story version:

Bought MME 02-22-2022

MME 08-08-2022 for defective pump on front motor and repaired on 10-18-2022 with brand new front motor. 7K miles.

SSN four days later on 10-22-2022 when I parked in the garage. Plugged in the charger and got a FordPass alert for a charging error. Towed back to dealer. Took another month for the repair.

Ford offered us money to keep the car. We almost kept it but someone reasoned with us that if it happened again, we’d be kicking ourselves for not getting out of the “night-mare” when we could. It became the opposite of a dream car. We dealt with four months of frustration, most caused by a horrible dealer in (cough Metro Ford) OKC.

Manufacture Buyback on 02-21-2023. Exactly one year from purchase. Mileage 12416. Rocked to Green Day songs on the way to the buyback (frustrated to be selling it back to Ford) and American Idiot was the swan song as I pulled in.

I’ve been watching the forum since then and seeing that my “second version” HVBJB is failing for others, I’m glad I took the advice to give it back to Ford. That being said, I’m willing to buy another Mach-E but I don’t have the patience for the bad dealership warranty experience and stress I went through. I found two dealers (found in the long story, not posted.) here that I think would give me good service so I’ll probably wait for the second gen. If it wasn’t for two particular members. One asked to remain anonymous and at one point they sent me the best PM that made me laugh so hard - “I hate your dealer.”. They know who they are. 😉 I think the repairs would have taken three times longer.

And this is the SHORT version!

Now the survey is starting to look more like what I expected, as the number of 2021 failures has surpassed those of us who have not had a failure. Even at 50%, it is a very high failure rate. Very high.

With a bunch of people with known HVBJB failures in 2021 GT and GT-PE MMEs tagged, calling their attention to this thread, of course the proportion of responders reporting a failed HVBJB is high. Massive selection bias here.

Are you questioning this highly scientific and highly reliable study?

:cool:

The fact is there have been a lot of failures. And yes, the people with failed HVBJBs have been notified about this thread, but I am not sure the result will be biased in that direction.

I bet some of the people tagged don't even come to the forum any more and will never see they were tagged. They sold their cars and moved on. Meanwhile, those of us without a failure are still happily here. So maybe the bias will be toward those who have stuck around in the forum because they have not had the bad experience of a HVBJB failure.

Who knows?

I could notify a good 100 or so more from all the data I collected that hasn't been organized. Not all would be GTs, but I bet there's a handful in there.

I've been saying all along that I feel that I have a good idea of how many have failed and it's not less than 1% like some of these fanboy members, with no involvement, claim.

I would also say that it's not nearly as prominent of a problem post May 2022, but the problem still exists. I would really like to know if the newer models have them fail at a higher rate than what would be considered normal failure rates. That's the data that I don't have.

The member who is complaining is anti anything I post so it's not at all surprising that there's a complaint. There's also at least 5 people now that answered with option 2 and they don't even have a 21 GT so the data for no failures will be higher than it should be.

It's already clear that people can't read. Some of the respondents saying that have a 2021 GT, don't.

I'm gonna start a new poll asking what the average forum member IQ is.
I'm going to start a poll about your poll asking if they read either poll.

I think it’s safe to say that Ford hasn’t entirely figured this out. Honestly, I have been through two HVJB failures, in two different MMEs. First HVJB failure was a SSN, and it was before much was known about the issue, trust me, it’s worse than the SVS. I do think the newer HVJB is more durable, but I don’t think it’s immune to failure from normal operation of the vehicle. I do think that Ford could have handled this better, designed the car better, but it is what it is. I wouldn’t be surprised at all if I have another HVJB failure, even with the new part. I hope at some point in the near future Ford actually performs full rectification of the problem.
