1 Pedal Error and Front Power Train Error

[curdawg99]

Driving home in my 2nd day with the truck. I felt a "clunk" and got a 1 pedal Error and it turned off, about a minute later I got a front power train Error and went to only the rear motor showing any power.

It's now in my driveway and won't even turn on. It gives errors and then goes to accessories mode.

Shut off the truck, leave it off for ~20 to 30 minutes, then check again if it will Start in ready to drive mode with no errors or faults, it might be an aberration.

If it doesn't schedule a service pickup.

the 'clunk' doesn't sound good, but, before resorting to a 'dealer', remove the 12v NEGATIVE wire for a minute, re-attach, and then see what the truck does... this is akin to 'rebooting' a computer that is not responding...

Almost everyone has had this error at one point.

If it doesn't fix itself then talk to the dealer. If the truck has been sitting for a long time it could be as simple as a low 12v batt.

Really? Almost everyone?

Really? Almost everyone?

Maybe not everyone, but many of us, myself included have seen these type of errors, I've only experienced it a couple of times, turned out to be nothing but an aberration.

Ya, a lot of people didn't notice at first. Unless you looked at the status page, there was only a 1pd caution and reduced power available. The front motor power caution is new.

I believe most of the time, this problem is caused by a non-immobilization OTA update that causes communication errors on the truck's internal network. The OTA updates can be applied while the truck is running and can affect a number of systems. It has been known to cause the front motor to go offline because the motor can't communicate with the control module during the update. It is common enough that it's happened to a good number of us here on the forum.

Always try the off-cycle that @TaxmanHog mentioned first. This gives the update a chance to complete. This worked for me.
If the error isn't cleared yet this morning, try the 12v reset @hturnerfamily mentioned.
Dealer visit if 12V reset doesn't work.

The clunk could be caused by the confusion in the control system with the brakes or regen when the motor went offline. Hoping that's all it is.

Checking in on this. Did you try anything to get your truck started? DM me if you need assistance with getting it towed.

This morning the truck seemed to be fine. I called the dealership and they still wanted to have it towed in. So they have it now and we shall see...Thanks!

I'm hoping it's a 12V issue since the truck had been on the lot for a while and from the looks of it, it hadn't been moved a lot.

Keep me updated on how you go. Happy to help if you get stuck.

Finally getting some info from the dealer service rep...I believe his words were "case study" as Ford is kind of directing the service. He said there are many people involved beyond his tech on my truck. Not sure if I feel comforted by that fact or alarmed.

Hopefully, they are investigating and find no physical problems. I wonder if the one-pedal drive error triggered an investigation since that changes the way the truck brakes.

In any case, keep us in the loop.

The team is hands on to help ensure that all goes well. No need to be alarmed.
