Yes, EVERYONE ELSE. Ongoing issue for two years now (Mach-E). Miles from previous trip may not reset. Try turning on the truck by NOT pressing the brake pedal. Then press the brake pedal and push Start again.

I've noticed this sometimes too, never posted cause I figured it was an issue that everyone had but I'm glad to see it confirmed now

I've tried every combination I can think of between pressing the brake and turning the truck on and off, I've given up trying to make it reset reliably. About once a week, I go into the log and delete anything that look erroneous and that seems to help my GOM (my speculation).
Are we able to generate logs from OBDII apps? I really need to find my adapter this weekend so I can start exploring the possibilities.

You can also log to a CSV file in the car-scanner app and use Excel (or tool of choice) to map/check your data.

I was referring to a log that would show a trip, and the efficiency of that trip, like the EV log in FordPass.
Correct me if I am wrong, but you can't simply use an OBD adapter, and Car Scanner, and pull up stored data showing that, correct?
What you are doing is much, much more sophisticated. And, you're storing the data as you go, right? You can't pull up the data for a trip from a week before you connected your box, right?

If the data is timestamped in the CSV, it would be trivial to write a script for trip logs. Definitely looking for that OBD adapter this weekend!

Well, yes and no.
You're right, there's nothing saved in the vehicle that you can access (that I know of anyway) after the fact.
But as long as you have Car Scanner connected/running, it can log anything you want and write that to a timestamped file that can be exported to graphs in the app or to a CSV file (example below).
This file can then later be used in Excel.
There's no good way of logging "real-time" energy use (that I know of), plus the speed of the interface wouldn't allow you to get the granularity to get accurate enough readings, so the easiest way is to look at "mpE" is the estimated amount of energy (energy, not SoC) left in the battery and simply divide distance witt that energy.
I do it this way in my black box and the result matches what the car/ford pass says when they get it "right".
[EDIT] And before someone corrects me...
Yes, theoretically you can look at the volt/amp on the battery pack and the LVB and figure out the usage and potentially convert torque/rpm readings on the motors to kW, but you're only logging so fast and each log value will be a snapshot in time vs. accumulated change since the last time so for this to work properly/be accurate you'd have to log every 50ms (millisecond) or so (which OBD isn't designed to do / handle) instead of every minute or in my case 15s.

Here''s a screenshot from last week. I'm pretty sure in this case that I didn't turn off the truck at a fast charger, but rather moved it away from the charger and parked before I shut down. So FordPass only looked at the state of charge when I started up, the state of charge when I shut down, and concluded that I had somehow driven nearly 150 miles on a half a kilowatt-hour.

No, it just didn't reset the mileage. And it used the 0.4kWh that you used to drive the less than a mile. Happens all the time.Here''s a screenshot from last week.

Yes, I have seen some crazy numbers like that as well. Most certainly a software programming issue. If you really want to know your efficiency you need to calculate it yourself the hard way using the odometer and the number of kwh you add to get back to your starting point. The app is fiction on this one

Why, why, why can Ford not fix this problem?
