Car Randomly Stops Charging

[Mach-Lee]

I sense an expensive recall coming.

No, because the melted charge ports are likely caused by using defective EVSE charge cords with poor or damaged pin connections. Some of the J1772s on the cheaper EVSEs do not meet specs and cause these overheating issues to develop. Using damaged public J1772s can also cause damage to your charge port.

Be careful what you plug into your charge port, since it could cause damage to your vehicle. I inspect the pins on unfamiliar chargers before I use them.

I've also had the exact issue others have reported. It started about 3 weeks ago with my ChargePoint. This other thread mentioned the same issue but referenced SSM 51513.

After further investigation I noticed my last Power-up version 4.2.5 was pushed on Monday 4/24. The issue started on 4/28 on my next charge at home and has been happening ever since. I have a 2021 model and have never had this issue up until now. This seems to be the case for others that have posted on this thread. I suspect this is a software issue so I plan to wait it out for as long as I can. After the glass roof recall issues I went through I try and avoid the dealership, unless absolutely necessary. For now unplugging and plugging back in works everytime to resume charging, but it's a little annoying.

Mine stopped working on the 28th as well. I know that distinctly... It was the last Friday Hood Meadows was open for ski season and I was going up there. Plugged the car in on Thursday night, went to get in on Friday at 7:30am and it had barely charged.

Thankfully Sandy has an EA station now that I was able to use.

I think an OTA update dorked up the LVL2 charging conformance. Or whatever that protocol is. It got f'd up.

Found this from another forum last year, similar issue.

All points back to something with Level 2 chargers. And more users talking about very hot charging ports/plugs. Sure seems like an update is telling the cars to not handle higher output (I'm on 40amps to a Grillz-e)right.

This weekend I couldn't go more than 40-45 minutes before charging stopped. I decided to try the mobile charger using the same 14-50 outlet my ChargePoint was plugged into. Charging was a bit slower I think it was around 6-7kW, but charging completed for another couple hours with no issues. Last night I went back to using my ChargePoint, the same issue happened again. Since I set my ChargePoint to 50A, I changed it to 40A, then started charging again. The charge rate dropped from the usual 9kW @ 50A to around 7kW @ 40A. This time around charging completed without issues.

At least this workaround solves the annoyance of having to unplug and replug in the charging plug. I'm still holding out hope this is a software issue in my case. I never had the issue of the port being hot to the touch at any point.

I can't go more than 30 minutes on a 40amp Grizzl-e that is externally mounted. There might be a way for me to open it up and set a dip switch or jumper pin, but frankly this is a Ford problem.

I'm going to get a case open with support (that will be useless) and then basically go to war with a dealer over this *not* being my problem.

Something OTA that last week of April screwed the pooch.

Have you charged at any other location to see if it is just your Grizzl-e or if it follows the car?

It's okay at Electrify America stations. This is following what others are noting in this thread that it's unique to Level 2 chargers operating at higher amp ratings. I don't have much access to other chargers of this type. Several us had the same issue pop up within the same day.

That's more than a coincidence.

Ford's OTA model has been absolute trash. Every update it's a question of what was broke and what setting I need to reset.

Who else had I pop up after the same OTA? Eraser said the issue so far follows the charge point unit. Dancoon never mentioned an OTA and did indicate the charge handle might be getting hot.

It started for me after OTA 4.2.5 on 4/24. My ChargePoint has the issue when set to 50A, dropping down to 40A it works fine. The Ford mobile charger worked as well on the same outlet, but I think the that is because it operates at a lower amperage.

Pulled the front off my Grizzl-e today and kicked the amps back to 32 down from 40 and the car went a full 2.5 hours until fully charged. First time it went more than 30 minutes in almost 3 weeks.

No clue how to get Ford to move on this. It's not something a car owner should be expected to troubleshoot and repair on their own.

Well work around. This isn't a fix. It's most definitely a work around.

Yeah it's pretty lame to have to go through that. If this was as software issue I would expect this would be getting a lot more attention from others. It just seems like a odd coincidence that some of us are having the same issue right around the same timeframe.

My car started randomly stopping charging a few weeks ago. At fist I blamed the L2 chargers at my work (8kW). But then it happened at my house (also 8kW). Took it to my ford dealer and they charged it on their 5kW charger and told me it wasn’t broken and would do no further diagnosis until they could reproduce it. Not sure what to do here.

If you change the amperage on your home L2 charger to under 50A it should charge fine. I've had zero issues since I did that. Prior to that change my car would stop charging every 40 minutes or so.

On a related note I just got Power-up 4.2.6 today. This update mentions changes to the charging port. I'm hoping this is the June fix for this issue. I'll report back later this week when I charge next. I'll see if charging stops when I set my ChargePoint back to 50A.
