Ford Mustang Mach-E 4.1.2 + GOM off here's probably why Screenshot 2023-02-08 at 2.34.55 PM


This is a 8.9 mile round trip. As I was trying to leave my driveway I was trying to turn off the AUTO ac settings as the car thinks it's 91 out. It's 67. The cars temp sensor says 91, it kicked the Auto climate on to high and AC on. So I clicked a few times and the lag of the 4.1.2 on my Job1 caused me to click through the Auto button like 3 times through the full cycle and I cycled the AC button as well. I drive this 8.9 mile route twice a day (for nearly 9 years in another EV). Never has it registered 9 miles. Almost always 10.5 to 11 miles. Using the nav to return home from my daughters school takes me the same route I use to get to the school. It says 4.4 miles from school to my house and vice versa. The AC was off once I left the driveway. 0.5 miles down the road I had flipped to "this trip" because it was showing (in the little tile) 2.2 miles/kw. 4 miles later after a quick mile on the freeway it's showing 7.8kw/h.

I'm thinking it's acting like my FFE where if you cycle the AC you 'gain' a ton of range. Like 25+ miles of range. But if you cycle it twice it'll put you negative 5 miles from Key on (30 less than when turning the AC off) then if you cycle the AC again you'll get 20+ miles of range and the kw/h come up with something crazy at the end of the drive like 5 miles per kw.

@Ford Motor Company If I managed any regen at all it was a couple feet at most. It's really hard to try to calc milage range if the climate 'adds' miles to the trip you didn't drive. I can somewhat understand using the added miles to help estimate but no way my drive can be twice as efficient as reality.

it's showing 17.8 miles for a 8.9 mile trip. thus the 7.8mi/kWh. My car does this (Double counts the driving distance) occasionally on the run to work... I doubt this affects the GOM because my car has done this for more than a year and the GOM only changed with 3.6.2 a few weeks ago.

The app did that long before 4.1.2.

A bug that’s been around for a long time that they don’t seem care to fix

I've experienced this bug several times in the 1month+ I've owned this car. It's crazy to hear that it's been happening for over a year and hasn't been fixed. Since 4.1.3, I'm reasonably OK with the Sync software, but the FordPass app needs some major work and investment.

I only used the app as the screen shot. The issue is being seen in "This Trip" in the car. It's even different between This trip and FP. Another mile to 1.5 miles added to the distance.
I left the house this morning and it showed me again using almost 4 miles to make it to the end of my block 1/8th of a mile down the road. It looks like a stupid padding of the milage for climate use. Smoke and mirrors but I can kind of see the logic on it to help guide people to realize climate use costs miles. But To look down and say wait. I drove 24 miles this morning, not 28.8 like it says. But I did have the heat on. So it's padding of milage right off the bat makes the tiniest amount of sense.
