Have received the same error but the car was not charging. Ran errands, parked in driveway, and walked away for an hour. Jumped in the car to pull it into the garage and received the Powertrain Malfunction/Reduced Power error. Have followed the instructions in the link above with no luck. Before pulling the LVB, would a factory reset work? Car seems to drive fine and charges fine off our ChargePoint. Called dealership (actually called closest four!) and earliest date for an appointment is Nov 5. Thanks in advance!

Since you have a GT, do you have 21 jail bars? If so, it is likely an HVBJB. If not, it’s probably not the HVBJB. ??

No jail bars or any other "weirdness" besides the warning on start and the orange wrench. Manufacture date is 08/23 so I think it has the "fix" straight from the line.

The LL9Z-10C666-C HVBJB wasn’t cut in until mid-November of 2023, but this isn’t your problem. O
If you have an OBD-2 reader, you should pull your DTCs. ??

Gotcha. For some reason I thought anything past summer retooling. Scanner on the way. Thank you!

I got the infamous "high-voltage battery warning" today.
Can you look into mine?

Codes reported this morning. I see there was a P1A1E:66 code that triggered the SSN, which means the car was being cycled on and off too many times in a short period. This is caused by either turning the ignition on and off too many times in a row, or from charging starting and stopping too many times in a short period. The latter could be caused by a bad EVSE or a bad plug connection (such as not plugging in the car fully).

I'd suggest doing a charge port cleaning and J1772 inspection for defects: How to Clean and Inspect Your Charge Port

Again, could be a bad EVSE, a bad J1772 handle, or just not being plugged in fully. Vehicle will fully reset afterwards, it's not a big deal. But if it happens again, you should take further action (such as replacing the EVSE).

Which EVSE do you have?

There are several threads floating around from various points in time with people reporting the same issue as OP. I have it too. And I had the same error codes. It's cycling the car on and off due to some kind of charging bug -- when the car is plugged in outside of preferred charging times, some of us will sometimes observe the car "cycling" charging on for a few seconds before stopping abruptly, and repeating this loop for about 10 minutes before throwing the errors reported.

I'm trying to figure out a common thread, but so far everything points to an intermittent software bug.

It's like the car starts to charge before realizing it's outside of the preferred charging times, so it stops, before subsequently trying again. This cycling leads to the error. It just occured for my 2023 GT tonight again.

Try plugging in the L1 for 10 minutes and then switch to L2. If that works, you have something similar to my issue and it’s temperature related. Is it cold where you are?

It is, but this was happening in the summer, too. Doesn't seem to be cold-dependent for me, anyway.

Does the L1 trick work, though? Just curious if it fixes your issue.

Haven't tried that, but I most certainly will next time I see it. I'm pretty sure almost anything that cycles the car and/or its charging system on and off, like powering on and off, or swapping the charger out, will resolve the issue temporarily

Have a similar issue with the FCSP and my MachE. My lightning charges fine -

Preferred Charging times are set in the car and appear in the app. I plug in the FCSP to the vehicle. First go-around the car will usually say "Waiting to charge at <random time>"

I will then unplug and plug back in and get it to say "Waiting to Charge at 00:00" which is correct since I have my vehicle set for 12a-6a.

Then comes the fun part, the vehicle then seems to hit a reboot loop and will turn on and off the charger every 10-15 seconds. In Fordpass you see "starting charger" then it goes back to "waiting to charge". Rinse and Repeat.

I'm at wits end and Ford just wants me to "take it to the dealer". We all know what happens when you take it to a dealer and its not a TSB or reported issue. Was hoping someone would have had this addressed by now in an official capacity.

This sounds like me, just last night lol. It's definitely a software bug, and so far I haven't found a way to reliably reproduce it. I do feel as others have mentioned that it's somehow related to the charge window beginning at midnight which is the next day. I wonder if setting it to 11pm instead would end it, but I'm trying to avoid charging during mid-peak hours.

I did change the setting to 1am instead of midnight, and I didn't have an issue last night. So silly that these are the things that have to be done with an EV. Charging is one of the most important parts of the vehicle.

Glad that worked, but keep an eye on it. Mine will sometimes be fine, but I still have it set to start at midnight.

Had this happen today. Charged to 100% overnight with the Ford Mobile EVSE and had a departure time set to 9am. Went out to start loading the car at 8:15 and the pumps were running. At 8:30 I heard the HVBJ cycle 3-4 times and then got a charge error in the app. 10 minutes later unplugged, tried to start the car and got the SSN error. Pulled the negative terminal for 5 minutes and it went away. Haven't had a chance to scan the error codes (do they survive the battery pull?). It was about -6C outside and probably 5C in the garage where the car was.
