Charging issue

The reply I received.

“Good afternoon Frank, thanks for providing further details to support the investigation.

The team has evaluated the described condition on your 23.5MY MME. The understanding is that it is natural characteristic of the new onboard charger and is nothing to be concerned with, on the MME 23.5MY.. if you need further clarification, please let us know.

I assume the other shared is also a 23.5MY facing the same conditions.”

??‍ still seems odd to me

Same reply I got when the technician contacted the BEV team when my level 2 EVSE set At 40 amp 9.5 kw, goes up and down between 9.5 and 6.5 kw the entire time yet is steady if set at 32 amp 7.5 kw.

at least they got their reply down pat

What this feels like outside looking in with extensive software engineering experience, is an off by one error in the code for charge levels, where 89% is really 90% and when the software compares charge level to completion it thinks it's 89% when its really 90%, so the BMS backs off to a very low charge rate, but never gets to 90% due to a code error, What makes me believe this is the moment I unplug in both cases, 89% or 99% the charge level instantly jumps to 90% or 100% respectively.

Last night I plugged in about 8:00 pm, it finished charging about 10:40 and at that time it had added about 22 kWh to get me the 84 miles it added.

When I looked at FordPass this morning it showed 71.1 kWh had now been used.

Something doesn’t appear to be adding up with this being “natural characteristics” from my perspective if it used almost 50 kWh to do whatever it does after the max charge was reached while making the humming noise.

No, pump should not run 24/7 while plugged in. Some stuff might be different with the new charger, but that doesn’t make any sense. Waste of electricity to keep running the pump endlessly.

It's for sure a problem, and the fact Ford keeps trying to gaslight me is comical, One thing I think is one system is 0 based and one is 1 based, where 89% in one is 90% in the other, I seen the same excessive usage from FordPass but didn't match the actual usage, What I see is when its sitting at 89% and I unplug it instantly goes to 90% so that makes me to think two different systems within the car are using different software and they don't agree on charge levels, At least I park outside, so if the car goes up in flames it'll only take my F150 with it and possibly my front porch.

So an update. I left my car at the dealer for a week, in talking with Ford field service engineers, they tried a number of things which didn't work. I'm almost positive it's a software issue which means ford engineering is going to have to fix it.

Checked with the BEV team today, at present they have no fix for the issue and can't tell me any more.

So at what point do I start pushing for a buyback, or I guess I can just take the car to the dealer and let it sit.

Not being able to schedule charging seems like a pretty big deal to me.

Any idea what they all tried? I’ve got an appt n Monday to do a PMI of the SOBDM.

You should be able to delay the start of the charging at a minimum. In the meantime I’m just going to not let it complete the charge unless I am able to unhook when done. It needs to be fixed though before the weather gets colder and I want to set up daily preconditioning.

I talked with the lead tech at the dealership Friday before I took it home, I mentioned some issues with modules but none of that stuff worked. I can set up charging schedules, and it starts charging at the designated time, but when it reaches my charging threshold it stops adding kw but the charger in the car keeps running and the blue light at charge port stays on. I can manually shut off charging, which is what I'm doing now, a bit annoying , but not the end of the world.

DM me your VIN and I can see what they did. I work at a Ford store.

First off, I looked on this forum for quite some time to find a similar issue.
To preface this, I'll mention for nearly 2.5 years I used the exact same phone, evse (Juicebox 40) for my 21 mache premium.

A few days ago my ordered 2023 GTPE arrived. I set up charging using fordpass, set up "saved location" for home with charging period nightly 7p-6am to 90%. Twice now I've charged the car. It hits the 90% threshhold and doesn't add more charge after that, the concerning thing is I can still hear the cooling pump hum and also the blue lights next to the plug are behaving as if charging, ie the last blue light is flashing, ie the last 25% charge.

I do seem to get some connectivity problems with the car and phone.
So I'm going to delete the saved location, but this time when I set charging up I will do it in the car on the sync 4 screen. Not sure what else I can try.

Exact same issue here. August 2023 Mach E premium eAWD. It never stops charging. The app says it is constantly pulling power. Tried resetting up charge locations. Didnt work. I just tried deleting the charge locations and letting it go to 100%. It stayed at 99% for hours and never got to 100 until I unplugged it, then it immediately jumped to 100%. Then I plugged back in. The app now says it’s not pulling power and the humming sound when charging is way less loud, but the Grizzl-e charger still shows it’s giving power. This is extremely frustrating. I need to see a daily power usage report from my power provider to verify if the car is indeed infinitely pulling power.

My most recent incident was similar. It stayed at 99% for hours while making noise up front.

I drove it 8 miles, it stayed at 100% the entire time and the range didn’t change. Next time I started it, still at 100% but the range was now less. ??‍

Hi Guys,
Both of you should give ford cares a call and get a case opened with BEV team 800-392-3673. The more cases opened better chance to get it fixed

I did open a case. Their answer was they have seen another case like this, and then I should try using the Ford charger and see if it does the same thing. I don’t have the Ford charger yet since I bought the car in the evening after the parts department closed and it was not in the trunk of the car. I keep being told they are sending it to me, but I bought the car three weeks ago and still don’t have it. I am betting the Ford charger will not make a difference.

Ford charger won't make a difference. All the "chargers" are in terms of AC are EVSE, the AC power converter etc is buried in the car, the external EVSE "charger" is just a power source. My car spent a week at the dealer and they used their own charger and had same result as me.

Something I did notice, they were charging it 100% and as someone else mentioned it never moved past 99%, I also noticed on fordpass that after some time the charging kw dropped down from 8 to <1 kw.

So I think I've heard from maybefive to six people with the same issue so absolutely must be manymore. An EV you can't schedule stopping and starting is a pretty big pain. My BEV point of contact said she'd keep me posted and she's been a terrific help. at the minimum I'll call them once a month for the next three to four months, and if still no resolve I'm going to push for a buyback.

Also, as to ford charger are you speaking about the portable that used to come with the cars? If your car is a 23.5 it was made a $500 option, otherwise you won't get one. Prior to that they came as standard equipment

Yeah, I’m talking about the one that used to come with the cars. I thought the car would not come with one of those anymore, but the salesman said he would ship me one. They told me they shipped one, but it got damaged in shipping and returned to them. he said they didn’t have any more in stock and when they get one he will ship it to me. I find it hard to believe that a dealer that had probably five or six Mach E on the lot don’t have at least one charger in stock.
