L2 charging speed recently dropped 33%

[Shayne]

It is official the MME charging like shit is a normal characteristic of a Ford EV now. Ford OTA making your car worse is their slogan now. It took 26 months and a lot of being jacked around but Ford finally came clean that they installed software to depreciate our cars and it is now a big FU. With ethics and integrity like that I can see them doing well in the future. After the cover up and bogus software for the HVJB and then again with home charging I will be looking elsewhere for my next one. Looks like with no class action I am screwed. @Ford Motor Company thanks for your support and care for your customers. Just a great organization.

There’s something wrong with your car- that’s not normal. I have no idea what actually transpired between FMC and your dealer, but it smells rotten.
I understand your frustration.

It’s not normal, but he’s not alone. Same update slowed my wife’s car. Have had everything replaced. No longer under warranty. But we set her car to charge to 90% and because it won’t hold a charge rate, it rarely gets above 80% by morning.

Stockfish Ford. So what should I do to get it fixed? Your guidance would be appreciated. The work order reads like an uneducated kindergarten wrote it but the answer is the same FU.

I know if this dealer gets paid they will fix it. They called me in for a second door fault because they had the parts sitting there for months and no work. I was not going in there again for that but they promised me progress on my charging and had check tests they were directed to run by Ford engineers. To me the door fault is all they did.

I have had nothing replaced just your software is up to date and Ford says there is nothing more that they can do.

I don’t have any good suggestions on what to do, sorry. FWIW, my car did the same thing - I have posts about it earlier in this thread. At some point, an update fixed it.

Is your car setting any related DTCs?

From what I understand from @Mach-Lee when the charging ports were melting and catching fire ford developed new software to throttle the charging and set a threshold of 80C with no DTC. The original which I had and worked flawlessly at a stead 40 amp for 2.5 years was 105C and at that point would throw a DTC which it never did. If the sensor they are monitoring is defective you are now sh!t out of luck. This thing now throttles when ambient air temperatures are at -20C. Pretty disgusting display of ethics and not too different then the HVJB they refused to fix however this is not a continuing safety issue and therefore the government will not force them to show common decency.

If you’re getting throttling at -20, there has to be a problem with the temp sensor in the charge port.
It should set this DTC:
SOBDM P1A3E - Battery Charger Output Limited - Battery Charger Coupler Temperature 'A' Too High.
If you get that code at -20C ambient, they should replace the charge port.

Thank you is this something new and different? What I have is them testing it in the shop now 3 times and it never charged over 8.3 KW and as low as 2.2 KW. It took 9.3 hours to charge it 66% in their shop which is an average of 6.5 Kw/hr on their 10 Kw ford charger. Of course they should replace the port and I have an email to them telling them that but Ford came back with that is normal and will direct them to do nothing. If you look at @Mach-Lee note the code is P0E5F.

NOTE: As of this writing, P0E5F (105ºC) will effectively not be set with the current SOBDM software, which limits charge port temp to 80ºC through a derating strategy. 105ºC will never be reached. A vehicle with a defective charge port will only experience a reduced charge rate, with no codes set (silent failure). Therefore I don't see this SSM being very helpful unless you are somehow still on the old SOBDM software that allowed overheat all the way to the 105ºC cutoff threshold.

Same here. I'm still heavily throttled. Dealer blamed the heat and claimed the OTA fixed it. I gave them the graphs and asked how making it take 40% longer to charge at home is a fix. When doing the math an 'over night fill up' is near impossible at 5.5kW on an ER car, unless you start ~18 hours before you leave. My garage is usually heat soaked to 105 degrees at 9pm (because, 7th layer of hell) and doesn't start tapering off until about 2 am. I'm 'lucky' enough and have done enough of this that it doesn't stop me, but others like Shane are hosed.

Here’s the TLDR of my saga:
My charge rate dropped 33% (early summer of 2023) at the same time a lot of others did. My dealer told me it was normal at that time. About 9 months later, after an OTA, my charge rate was restored. Maybe that was a coincidence, perhaps the flaky temp sensor quit being flaky. Then last fall, my charge rate dropped again, but 20 or 25% vs the original 33%. That’s when code P1A3E was discovered. I don’t know if that code was getting set when I first saw the 33% issue or not. I took the car to the dealer and described the problem and they replaced the charge port which corrected the problem.

Mine throttles pretty much right away and at 20C all the way down to -20C never see it hit 40 amp too often anymore. It will average around 6.5 Kw/hr and no more which will not work for anyone's heavy commuter. I agree this take so much value out of this car I can no longer sell it privately and screw someone like Ford has screwed me. Be a long long time before I would buy anything else from the unethical @Ford Motor Company.

You have that code but will Ford do anything about it?

@ Both I truly appreciate long term reputable members like you two speaking out and letting people know what Ford has done and what they stand for. Never know a company until you have problems and now I know what Ford is like. Their own design errors get passed down to the owners with a big FU. May not be able to do anything about it but we can sure let others know. Money must have traded hands at motor trend.

It is telling that one that thinks he knows all about the MME has nothing to say here even if flagged multiple times. Link

Edit: My bad @ you 3

I had that code being set every time I L2 charged. Dealer replaced the charge port and I no longer have throttling or the code. That should be the universally-applied warranty fix.

I have heard (3rd-hand) of dealers refusing to take action even when that code is present.

You have another option - paying out of your own pocket to have the charge port replaced. But I would only do that if 1) P1A3E is getting set every time you L2; and 2) You feel the value of the car as it sits is being hurt by more than it costs to replace the charge port.

I really feel bad about your situation - it sucks.

I have been having issues for a while and noticed the issue in last year, but could have been even longer. After getting fed up with the slow charging, I finally had the dealer take a look in the last month. I was searching for people with this issue and thankfully discovered this thread and read the entire thing.

my situation:
2021 Job 1 Mach-E. Car starts charging at 8.4kW but quickly within minutes drops to 7, 6, 5 and eventually 4kW when charging on my 40 amp grizzl-e charger.
Tested another 2021 job 1 Mach-E on my home charger and it doesn’t experience the issue.

Tested my car on multiple chargers and am experiencing the issue.

I would bet that if there was a way to see when it started, it was probably around the same time mine started. Christmas of 2023 if I recall. Welcome to the club. is it a problem, yes. Is it a problem that I can’t get around, no. But it does mean my wife has to charge outside our off peak discount rates sometimes.
