My dealer has been informed it now charges like crap and I would like it fixed. He is waiting to get the next steps from Ford.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.
Also got 4.3.5 this morning which is another update to rule them all (think we had an update for updates before). What did they break with this one
90KW x 0.57 / 8hrs = 6.4 KW/hr 32 amp is 7.7 kw so 84% efficient makes sense. Welcome to the 32 amp charging club. Mine messages it will miss target every time it starts the schedule but then may make it. It is down to 32 amp now also. My charging handle gets warm but nothing that is not expected. After 2.5 years of working software now says it can not.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.
