I never used the app for this. I suspect this is more the app than anything else. I always program this in the car.
If you have a consistent schedule that works. When your schedule changes all the time it would be nice not to have to go out to the car in -20C to set it. I suspect it is a car sleeping and lack of solid servers. Bluetooth communication would fix it but that will most likely never happen. Right after the frunk button may be?

So was at the dealer. They suspect it's the wiring harness with from the port since the temperature sensor was reading the wrong resistance. There was also a hidden fault code in the system to indicate as such which occurred around the date of the DCFD update. The harness is only available in the US so 2–3-week delay. My opinion, those of us with issues had a defective temp sensor in the harness. This only became apparent after the DCFC update throwing an error code indicating an out of spec result from the temp sensor. This probably caused the system to go into some sort of protect mode where the car would allow charging but only at lower amperage and by throttling the charge resulting in a sawtooth pattern.

They couldn't replicate my Bluetooth issue, but they wanted to do a master reset. I decided not to because I don't think it would resolve that issue but that's for another thread.

So that's my update.
Hard to believe it was working like a champ for 2.5 years and now after a software update it has faulty hardware but sure. The joy with this car never stops just keeps wanting to spend half its life in the shop. Not good news.

Some noted they changed the harness and were now looking for something else.

BTW for those of you that keep on asking if the extended warranty is worth it? The harness costs 800$cdn+labor (145$/hr) which without the 2400$ warranty i would have had to pay myself. I busted my kms, I'm currently at 65000kms. The base warranty is 60000kms.
That was a no brainer after buying this car and seeing the electronic mess we bought. I purchased an extended warranty before the first year past. I was going to see how long an EV can last but based on the first 2.5 years and that it appears it will never end not sure this one will make much more than the warranty parked here. Wonder how many are past the warranty before they throw out software to flag a hardware problem. The outstanding ethics just keeps repeating itself.

I know this is why I have to believe that it was already out of spec from factory. The error code thrown occured after the update which shows that the update detected an issue. Again ill know more in a few weeks. If the harness fixes the issue I can definitely see this becoming a recall with the number of people having this issue. The problem is that unless you have a 48 amp EVSE or a smart EVSE you might never know you have an issue unless you're timing your charges.

As one of my favorite youtubers says "they might have an issue but they might not have found THE issue."

Their are a few here that it works perfect but then again would they even know? I do not need a smart EVSE to calculate % charged x 90 KW/ time (Hrs) = charging speed. Calculated it a number of times and was always over 8 now 6. I do not have 48A I have 40A that now charges at 6 KW. As you noted it is good that it is still charging. I will sit back and see where you and others go unless it stops charging completely or starts throwing errors. Really tired of this being in the shop all the time. Hoping for a software fix this time not over heating up he so we do not need the California Arizona fix. Was working great until it was told not to so still hoping for a software bug and not finally flagging a safety concern.

Edit: This should be part of the E-systems and covered for 8 years 160K KM?

Shouldn't this be included in the "Electric vehicle component warranty"

Thinking about it a bit it is the HIGH VOLTAGE BATTERY AND eDRIVE SYSTEMS in the warranty not the charging so they may argue it is not. Possibly they waited until 90% of job 1's were out of warranty prior to dropping a safety concern update? Possibly just a buggy update? Time will tell. I can see some that need the 40 - 48 amps to meet their schedule and 12 hours (@ 6KW) to go 10 to 90 will not do it for them.

The warranty listed in fordpass for my 2021 says this about the electric components:
The high voltage battery and eDrive systems of your vehicle are covered by the Electric Vehicle Component coverage for eight years or 100,000 miles, whichever comes first. High voltage battery and eDrive components covered by this warranty include the high voltage battery assembly, Bussed Electrical Center (BEC), Battery Energy Control Module (BECM), on-board charger, Inverter System Controller (ISC), DC/DC converter, and eDrive. If a covered component requires replacement under the Electric Vehicle Component warranty, it may be replaced with a new, factory remanufactured, or factory refurbished component, at Ford’s discretion. Refurbished battery components selected for your vehicle will align with your vehicle’s age and mileage and meet Ford’s requirements and standards.​
I would logically expect that the charge port or whatever part is overheating here would be considered part of the "on-board charger".

I'm actually experiencing worse results than the charging just slowing down but instead if I try to start charging at 40A or more it will charge for a few minutes then stop and report "plugged in not charging". If I start charging at 32A it will function but will toggle between 6kw (24A) and 8kw (32A) every few minutes as people are reporting here. I don't care so much about it charging slower - although that's annoying. I care about it not charging at all and being stuck at some hotel hundreds of miles away because their charger is 40A or more and I can't even get a charge to start.

Not spelt out like that for the 2021 warranty info I had download before I bought. Just says eDrive systems with no indication what that may include but read as electrical drive train. Not sure what is going on here as normal absolutely no transparency from Ford. Drop it on some and there you go figure it out.

I've got an appointment with ford on Monday (the 17th) to have them take a look at my charging issue. I'm at 53k miles so I'll let you know how the warranty stuff turns out.

Is this consistent with what people are seeing when they need to get the charge port replaced? I finally broke down and pulled out car scanner and got this just before the car stopped charging.

The circled values are AC charger coupler temp

I have the report from the dealer picked up the car. Apparently the error was thrown multiple times over the past few weeks in the sobdm module (on board charging module) So for all of you who are having issues you can point your dealer there. Its the p0E5F error https://www.macheforum.com/site/threads/p0e5f-error-in-sobdm.26060/

This seems like its going to eventually affect all cars. I didn't expect it to fall under the battery warranty because you can't really consider as part of the drivetrain. Example: a gas tank or fuel pump wouldn't be covered under the drivetrain warranty.

The 183F is actually the charger internal temp, not the charge port temp. Anything above 180F is too warm. The 287 number is just plain wrong, ignore it.

Looks like your charger module is overheating slightly. The cooling fans should be running at that temp.

I discuss these numbers from Car Scanner in a recent post:

Oh that's excellent! I'm going to have to analyze that a little bit more closely. I think my next step then is to check out the numbers with fdrs. Because as it stands I can charge for about 10 minutes on 48 amps, and 30 to 40 minutes at 32 amps...

Not acceptable at all

(And yes. The fans were going full blast)

I haven’t used the car much since I was traveling- started to charge up tonight at 32 amp (unit is a Juicebox 40 amp plug in)

for about 30 minutes or so charge seems normal. When I remembered I had derated it to 32 amp, I changed to 40 amp- you can see from the attached picture what is happening, ping pong effect. I noticed this once before when charging right before I left on vacation but thought it was the juicebox unit. Guess not.

I have read bits and pieces here, is this strictly from a software update or will hardware need to be replaced. I would think software.

BTW my car is silent not normal cooling noises coming from it.

Right now it seems a software issue discovered a hardware issue and we will have to wait and see.
