Updates on the HVBJB (22S41)

[ohmslaw]

I've said it before, why would they replace parts that have not failed????? There has been a few batches of suspect contactors. They adjusted the car to fail in a safe way.

There is NO reason for them to replace all the hardware. NHTSA won't care, there is no safety implications anymore with the software update. Ford has already worked with them.

Admit it, this has nothing to do with safety.... You just don't want to be potentially inconvenienced.

Not every HVJB failed, or will. It seems there is a somewhat perfect storm of things that help it fail. For some people that might never put the foot fully down it might never fail. So yes, Ford won't replace those. It looks like out of the MME's sold to date there is a pretty low fail rate. If it's below a certain percent of cars on the road it doesn't qualify for an all out recall as it's a potential for failure rather than a promise ticking time bomb.

However that said, every time I put the foot down I get a little nag in the back of my mind. Having the updated software to at least tell me it's going out and allow me to drive the vehicle is far more better than a 1/2 day on the side of the road and a flat bed. I'm pretty sure due to the low amount of failures they still havn't pinned down the chain of events to set off everyone claymore. If they do I bet you would see reduced power here or there first. Replacing a $700 board for Ford is way more than just the board as the pack gets dropped from the car.

We have a resident nut case that's out trying to blow up HVJB's and has done in 4 so far. So, much like suspension work, it's still in research phases.

in order to prevent overheating your HVBJB,


1: never go up a hill while accelerating
2: don’t fast charge after driving a while
3: don’t try to pass anyone on the highway by stomping down on the accelerator
4: don’t drive your car.

only #4 pretty much guarantees your HVBJB will last forever.

So essentially this is a permanent defect with the Mach-E that is tentative not avoidable all together with a future software update or part replacements?

Think of the software update as a smoke detector. It does nothing to fix the problem, but tells you about the problem as early as possible.

The ultimate fix is an updated HVBJB

I'd much rather be able to drive it in than push it in lol.

I am fine with fix after it breaks. But what if it breaks after warranty? Does anyone know if the HVBJB replacement is covered after the bumper to bumper warranty? Is it covered after the powertrain warranty at 60K miles? I am planning to keep the car until at least 100K on odometer. Don't want it to break later and have to pay for a known defect.

That is my main question. I don't actually care about a proactive fix if Ford covers it for a reasonable amount of time.

The warranty on EV components is 8yrs/100k miles.

Correct. I just got ‘blessed’ today actually… ?

Dang! Sorry to hear that. On the bright side you got yours out of the way and it’s onward to better days

I’ve got stock in Ford and I still wouldn’t defend them to this point.
I’ve heard the repair can take in some cases up to a month. Do you want to be inconvenienced, not sure that is a sound argument to lay on people who simply don’t want to deal with the headache and the small fact that your paying $50K plus for this vehicle. Just my two cents but I’m expecting ‘angry dad vibes’ on the next response.

No, it's angry engineer vibes. They have unknown quality contactors from a supplier. Engineers came up with a way to detect when a failure was about to occur. The car goes into a safe mode when this occurs (power like a Prius) and you can keep driving it. No different than a failed map/maf sensor in a ICE vehicle causing it to go into limp mode, in fact this is even better than that since the car is still livable as a vehicle.

With a competent dealer that has parts on hand it shouldn't take more than 3 days. My dealer did it the first time on mine and it took 6 business days from in shop to fix (they didn't even have parts on order).

Parts are avalible and the repair is only about a days work. I never let it worry me, it was going to fail at some point. That said it got towed to the dealer friday evening after the died without warning, I should find out tomorrow it that is what indeed failed.

I feel like I’m feeding the troll, but being stuck on the side of the road is a major safety issue. Try asking someone in law enforcement how they feel about being on the side of the road and how many crashes happen with drivers who aren’t paying attention who ram such cars at full speed. Oh, and what about those of us who want to go camping or to a trailhead? Cell service may not be available and flatbeds aren’t making it up to many trailheads, at least out in the west. But sure, I guess since it’s not a problem for you, personally, it’s not a problem for anyone.

You’re right , who in the world would want to be inconvenienced being 800 miles from home is some deserted area with no Ford dealership around in the middle of the night. Safety doesn’t come into it, really!!

what if it’s my wife driving the car at all hours like she used to when her mother was ill.

I wouldn’t let her take it.

Don’t tell me it’s the same thing as a tire blowing out or whatever.

ford admitted this is an inferior part, their “fix” doesn’t guarantee you won’t be stuck somewhere only reduces the chances.

would you feel the same if they said, the tire was made of inferior rubber and is substandard and may fail but don’t worry it’s a run flat, you can drive 50 miles to safety (Of course your 150 miles from anywhere at the time). You would run to get that tire replaced Immediately.

You are using a false equivalency for your argument.

A tire blowout can be quite dangerous, suddenly limiting how far your car can go can be quite annoying. This does neither of those.

I had this happen to me while trying to merge onto a highway with my 2 year old in back. I've experienced catastrophic tire failure, it's nothing like it. Your car still functions as a car, we put on more than 200 miles after the failure before replacement. The car still functions.

The honest truth is you are overly cautious and upset it wasn't fixed how you wanted. You see a potential 'inconvience' and think that you should have it your way.

How many people has this stranded? The vehicle still functions.

Prior to the software update this was a dangerous safety issue. It isn't anymore.
