Way too DANGEROUS!

[Duncs]

Imagine driving down the road. You pull off the accelerator on your Mach E to slow down and eventually brake. It works. As you creep closer to the stopped car in front of you, your mach e continues to slow until OUT OF NOWHERE your one-pedal regen braking fails and your mach e -- at a time when it should be stopping -- lurches foward, throwing you into whatever is in front of you! It's scary. And Ford NEEDS to fix this known issue immediately.

After I got the HVBJB recall last month, my mach e would randomly lose the ability to slow and brake using one-pedal regen. It's a terrifying experience thinking you are about to slow but suddenly you're going faster. luckily, it hasn't resulted in an accident like the one described above. But I dont feel safe having my family drive a car that doesn't stop the way it's supposed to. I took my vehicle into the dealer three times. After updating every available module, they escalated the matter to Ford national techs. As communicated to me by my dealer, ford is aware that the HVBJB recall causes one-pedal drive faults and they do not have a solution. Yet they are posting here about available goodwill "gifts" for those who go get the recall within a certain time. Is Ford encouraging Mach e owners to get the HVBJB recall knowing that it will result in an unsafe car with a whole other problem?

I had zero issues with this vehicle before this recall. I guess the honeymoon period is over. What can I do? The dealership said there is literally nothing they can do and Ford acknowledges this. @Ford Motor Company I just want this car to work as it should and did before the recall.

Your car not breaking is a good thing.

But you‘re clearly talking about braking. What ”known issue“ are you referring to?

This is the first time I've ever heard of the HVBJB recall causing a one-pedal drive fault. Can you provide the communications you mentioned where Ford states this?

Interesting, they will probably provide a fix as soon as BC 1.4 rolls out. ?

I have heard of this on FB as well.

Service dept will tell the affected owner to not use 1PD as it will disengage.

While they wait for a part, they are supposed to use 2PD driving.

I suppose it goes without saying that you turned one-pedal off.

As it's been communicated to me, they don't even have a part that fixes the issue.

I guess that's my only option if ford can't fix it, isn't it?

My MME has had exactly the same problem since the HVBJB recall.

It's probably the wisest option for now, for anyone actually experiencing the problem. FWIW, driving with L gear engaged is nice way to get some of the regen slowing you're used to with 1PD, while still using the brake pedal for the final stopping. That way you're at least ready and prepared to hit the brake pedal instead of being totally out of the habit. Even if regen fails in 2PD mode too (haven't heard of that happening, but then, I haven't heard of this until now either).

Note that in the rare case you've fully charged are are sitting at 100%, regen may not work either (no room in the battery to add regen energy captured). Sounds like a different situation though.

My 2022 GTPE also had a “one pedal system failed” (or something similar) message show up about a week after we did the HVBj recall. Never had it before the recall at 18k miles.

According to the notice on the recall 23S56, the procedure should "... reprogram the Powertrain Control Module (PCM), Battery Energy Control Module (BECM), and Secondary On-Board Diagnostic Control Module C (SOBDMC). These modules are coordinated with the PCM, BECM, and SOBDMC and may also update: Antilock Braking System (ABS), Secondary On-Board Diagnostic Control Module (SOBDM), and Secondary On-Board Diagnostic Control Module B (SOBDMB)."

Someone much more knowledgeable than me can speculate which module(s) are most likely the problem.

A few notes.

1) I strongly suspect NHTSA will take this very seriously. Toyota got in serious hot water for an issue with ... Prius? .... braking. In those cases, I think the car went into full accellerate mode with the break pedal applied. OTOH, Tesla got in only moderate stink for the opposite problem of having the break apply when steaming down a freeway at 65mph. They pushed a fix in about two weeks. I hope NHTSA takes this seriously too - but the fact that it continues braking, "just" falls back to 1PD, it continues braking just at different, surprising, and unsafe rate, which can be described to customers.... we'll see I guess.

2) You say this is caused by the HVBJB update -the comms from your service department are a bit more vague - "and software updates". While it's all the same to you, someone else might get this software update outside of HVBJB and be effected, by my reading.

3) You say "there isn't anything Ford can do". I read the service statement differently. There's nothing Ford can do *NOW*. It's not clear they know there is nothing they can *ever* do. They could be working on it and push a fix - if software broke it, software perhaps can fix it.

4) On a personal basis, My MachE has internal communication faults. They are generally in the camera sensor systems. This makes blue cruise, lane keep assist, cruise control generally, not very reliable. My experience is that about every 30ish minutes of freeway driving I get a fault. The car throws a bunch of "lane centering not available", or "front facing camera fault", or "driver facing camera fault" dialogs, and turns off those functions, then about 10 seconds later, they are all good again. The codes relate to packet corruption on the internal CANBUS links. I did the trick of unkinking the one coax by the driver pointing camera, didn't seem to help. I brought the car in twice. Once I was given a .... "story"..... about how a leaf in front of the sensor can cause this failure. Sure, a leaf can perhaps confuse the lane keeper, but, sorry, it takes a very strange leaf to cause packet corruption in the car. Service was advised by Ford to ignore this class of error codes, I have the comms from service / ford. They do state over and over in the manual and on screen that the driver must stay aware of, and respond rapidly, to failures of these automated systems. And I do. The car does stay stable and pointed in the right direction, and is noisy about alerts and recovers fast, so there is certainly an argument this is not a safety issue like your report is. The driver does have time to react. I think its a safety issue because sometimes you're on a freeway in BC and there's a semi a foot to one side, and grabbing the wheel with a loud alert and red dialogs can be a dicey proposition. I've given up trying to get a solution, but I have to say I'm not crazy about this (consistent) failure mode and Ford / my dealer's response. And by "not crazy", well, I'm being polite.
