2023 F150 Lightning ER - Electric Powertrain fault and Powertrain Malfunction/Reduced Power

[supreet21]

I have encountered an error with a 2023 F150 lightning ER. Currently has 20,000km on it.
1. Electric Powertrain fault
2. Powertrain Malfunction/Reduced Power.
The maximum power output has been limited to 20. The truck is not charging at all, tried the level 1, level 2 and the fast chargers. It displays an error right away when I pulg in. I believe this happened due to a software update that failed.
I tried restarting the truck a few times, full shut down and start. Disconnected the 12v battery and repluged to fully reboot, no luck.
Any insights?

That update failure is not likely anything to do with your problem!
how long did you disconnect the 12 V and did you check It’s state of charge?

2. Powertrain Malfunction/Reduced Power.

See the main thread (below) on these PM/RP situations. Most likely one of the 96 cells in one of the nine battery modules is failing. Click on my tracking spreadsheet in my signature to see the hundreds of examples. What is your build month/year atop the sticker on the driver’s door b pillar?

The Bluetooth OBD dongles are very helpful to get a lot more details if you are so inclined. In addition to getting specific error codes, you can see if your battery might have a bad module like @GoodSam mentioned.

Take it to the dealer. Asap to get diagnosed and parts moving.

Time to visit the dealer service.

The battery array has gone bad. No way around it. Depending on where you are 5-7 weeks to get your truck running again. Request a loaner if one is available. Went through the same problem with 9380 miles.

An update for you all, it was the battery array module. It was at the dealership for over 45 days. I got it back, drove for 300 kms and another issue occurred.
Electrical Powertrain Fault - High Voltage Detected, got it towed into a dealership. They replaced the 12V battery, got it back from the dealership and the same error 'High Voltage Detected' showed up again within an hour from picking up the vehicle.
Got it towed and back at the dealership again.
Any suggestions or recommendations on how to deal with this?

@Ford Motor Company please help

This is awful. Have you called the BEV Ford number? I don't know where you live, but I suggest you open a file with Ford and begin the process for a lemon or buy back. Also, did the dealer provide a loaner car while the truck was in the shop for 45 days? The BEV folks should address that also.

The only thing I can suggest is to contact the BEV team… I don’t remember if you did that before as I have not read back through the posts!

I woke up to the same issues on saturday when I was leaving my house I didn't even make it out of the driveway when I got the same faults. I wonder if the recent Customer Satisfaction update they were hounding me to to for so long that I finally let them do two weeks ago have anything to do with this issue. I am at 57 available battery with a state of charge of 73%

57 available battery

Sounds like another type of fault. Did it go away after a key cycle or 2? Did it actually give a fault code or was it silent like the contactor issue?

IT has not gone away. I dont actually have a fault about the battery but there is a charge fault when i plug in. I also have the powertrain fault

This may portend a better situation, the charging system has a defect, which might be fixed pretty quickly, hopefully the battery pack isn't the problem, looking forward to the technician diagnosis.
