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.
