L2 charging speed recently dropped 33%

It helped, but I think it really depends on if your cars fan starts at all once plugged in. Mine didn't start until almost 2 hours into the charge when it actually stopped and started the charge by it's self. It was sitting all night in the garage ~ 105 degree soak at 9pm -> prob 90 degrees by 8am.

At 64 degrees I do not see a need for the fan to start but still charging at a slower rate here. Maybe ice in the frunk not for shrimp but for faster charging?

It just threw a curve ball. It's cycled the car fan twice, and restarted the charge, twice. Now it's charing at 40 solid with the car fan running on low and the leaf bower out of the picture. It's been charging for over 25 min (longest I've seen before a drop in amps) without the blower, the garage and all other temps higher than started and the cars fan running on low.

Something I noted about the way it's charing now, the air from the cars fan, is most likely cooling some other sensor somewhere. One that wasn't cooled by the leaf blower. Which would explain the rain having a better effect. With the way the fan is running now air if coming out of the wheel wells in the front. Remember my cooling fan never started this morning and didn't start until the first crap out. It has now charged to 85% and stopped (my target) without cycling the amps since the second crap out.

You could have multiple issues here. I think the port is still overheating some.

It could take a while for the fan to come on since everything in the loop including the motors has to heat up first. After that the fan should cycle on and off periodically. That’s how mine works. There are multiple reasons why the fan might come on, could be a battery cooling request (A/C will run) or another module like the DC/DC converter might have sent a cooling request too (that one usually jumps right to medium or high speed).

The interruptions are odd though, not sure what’s happening there.

Maybe the fan blowing on the backside of the port helps, but I didn’t see any effect on port temp in my tests.

Well I can tell you that as soon as i plug the car in the fans start. That is maybe at 40 amps it charge for 10 minutes at a constant rate and drop if the fans shut off. I'll have to check if the fans are still going after 10 mins. This could be the byproduct of the defective temp sensor.

My Level 2 charger in the garage has now done the same thing, almost to the day of one of the automatic updates. Used to get about 20 miles per hour added. Now its much less. KW went from 9 to 3 and I got the amber/blue light on the Ford charger. Its warm here, about 85 and humid but I never had this issue last summer. Also, tried to charge at night and got the same result. Should I report this to Ford, maybe get a new Ford charger under warranty or is it the software limiting the charging ability due to heat at the charge port?

Good morning- I can look into this for you. Feel free to send over a private message with your VIN and dealership information at your earliest convenience.

I got my car back from the dealer today, after having the charge port assembly replaced. It seems to be charging fine with my JB40, and the fan recycled on and off in my 80 degree garage.

Here’s a shot of the paperwork showing what was diagnosed before replacing the assembly.

Was this done as a warranty repair? If so are you still in your 36k mile bumper-to-bumper warranty or did it fall under the "Electric Vehicle Components" warranty? A bunch of us Job 1 owners are over the limit on our full warranty. Mine is at the dealership right now but they are still trying to "confirm" what they need to do so can't give me any kind of price yet.

The BEV team at Ford corporate did say that they were going to check if mine was on the list of "vin numbers affected by an issue with the charge port" so at least the issue is something corporate knows about.

Yes, it was under the 36k bumper-to-bumper warranty. I only have about 11K miles on the car.

Interesting

I Don’t have any engine light on or other obvious signs for my issues

Wonder if other have any thing like yours

This looks exactly like what the tech at the dealer told me. So harness swap really does seem to be yhe fix

The charge port assembly is only covered by the 36k warranty, not the 100k EV warranty (which makes no sense, but that’s how it is). If you’re over 36k it would require special permission from Ford to cover replacement.

Is this info from Ford? I’m afraid that’s what they are going to say when I hear back from the dealership, and is why I asked since I’m at 56k. Their EV warranty lists the parts that are covered and in that list is an item labeled “on-board charger”. It doesn’t list any specific part numbers. The charge port is logically part of the on board charger. At least thats what I’m planing on pushing them on if they say it isn’t covered.

Oops, it IS COVERED under 8/100k warranty now. They must have changed the warranty coverage on it since I last checked, that's good news.

LJ9Z-14A303-D is the part number for the charge port.

Sweet! If they tell me it isn’t I’m going to reply “but Mach-Lee said it was”. Thanks for the info and whatever digging you did to find this out.

That could be true. I just don't like how people are reporting it's charging at 40A in hot weather without running the cooling pump or fans. It's going to get hot and bare minimum the pump needs to run.

I did hear the pump at least running the other day when the fans wernt. The Fins were open but that's not enough to actually cool it at all. It charged at 40 +/- 28 for 2 hours without the fan.
I just got 4.3.5, but not holding hope that's the resolution.

I got 4.3.5 yesterday and had a charging session last night, still with the same issue. No change. If these harnesses really are faulty then hopefully there will be a recall associated because I strongly believe they were already faulty from factory for the update to affect it.

So I’m going to chime in on this thread. Because I believe I have the same issue on my wife’s car.
I posted a long thread early this spring where her car was heating up the charge port and the connector her Grizzl-E charger when set to 40 amps. It would then throw a charge fault and stop charging altogether. Same when she plugged her car into my charger. Slowing the charge rate to 32 amps fixed this. I should note that this began right after she received some update (4.1.2 I believe but don’t hold me to it).
Anyway we had the charge port and wire harness, as well as the SOBDM replaced. Things looked OK. But as we’ve been driving more over the summer, and plugging in with lower percentages, the car isn’t charging at the speeds it should. Last night it was plugged in for the entire 8 hour charge window and and pulled 57% (just under 52KWH). The car showed it was pulling 6KW, far less than the 9kw my car was getting from a twin of the circuit/charger setup. I can switch which car is plugged in to which charger and get the same results, her car charges slower. The EVSE plug handle that her car is plugged in to, gets warmer (by touch and by infrared thermometer).
I haven’t done any data logging on what any of her sensors are showing or seen if fans are running or not. All I can say is that since the update in December, her car throttles L2 charging speeds despite Ford having the car for over 6 weeks. And it isn’t anticipated throttling because the car doesn’t start charging before my set window, which shows that the car believed it would reach the charge target. But then I wake up to the car still not being completed and showing that it only averaged 6KW power.
So I’m hoping to join this discussion and see if we’ve learned anything or if we can prove to Ford that they’ve somehow messed up level 2 charging for us.
