I also received the dreaded error message yesterday, and from what I have seen, there have been other owners with the same issue. I have 3,048 miles on my Lariat extended range.
Hey! Can you please send over a private message with your VIN and the name & location of your local Ford dealer? I would like to see what I can do to assist with your Lightning's powertrain messages.

Good morning. I'd like to take a closer look at your Lightning's powertrain issues. To get started, can you send over a message with your VIN and the name/location of your local Ford dealer?

Just got my 4th warning in 2 weeks. Dealer visit tomorrow to diagnose. Will start a separate post, pro power has a test mode that is kicking a faulty circuit warning now.

Have you already verified your 12v connections are tight?

Nothing was plugged in when I tested
No I mean that is causing your other faults and if you have checked the actual posts on the 12v battery to ensure they are tight. Unless you are saying all of what you are experiencing is due to pro power test mode?

Not sure if they are related, I have checked the other posts but haven't seen anything about the 12v...will check now, thanks for the tip!

Both terminals are snug on the 12v

I have no warning lights, no messages, nothing. Woke up this morning everything seemed normal. I started driving and noticed my power was limited to 51%? Not sure what to do at this point. I just received 3.5.4 yesterday.

After executing the test, you must press the activation button in the bed to reset the trip condition, at least that is what I did after I tested mine the other day. (NOT A FIX FOR REDUCED TRACTION POWER)

Service department said the issue was the 12v battery, had it for a few hours. After tightening them the night before, thanks to @Gimme_my_MME, seems to be resolved, appreciate the tip on that.
