I have the Powertrain Malfunction/Reduced power message on my App as well as the wrench icon. My truck is a 22 5.0. The dealership called me back and they can’t find the issue.. mentioned something about checking the wiring and wanted me to leave it for several days. Anyone else had this happen with the 5.0?
Mine just came on today. 22 5.0. Just got an update last night too. Not sure if associated.

I first noticed the problem earlier this month when the truck wouldn't go into electric mode and the Powertrain Malfunction warning appeared. The problem then went away so I ignored it, but it came back again accompanied with Remote Features Disabled and so I decided to take it to my dealer. He quickly diagnosed the problem and told me there was a TSB for it. They replaced the auxiliary battery isolator and reprogrammed the PCM. After I picked the truck up I'm still getting the low battery issue - hopefully it will go away after fully charging the battery.

I had my truck completely die on me on the highway. App gave me the powertrain malfunction warning and an electric powertrain malfunction. Was able to restart after a couple of try’s and went straight back home. Have it booked for Monday when the hybrid tech is in. I’m hoping they find something as my trust in the truck is greatly diminished at this point

I get this same message every few days, typically around the same spot in the road. It isn’t every time, and I do get it at other random times too. I’d say about 50% of the time is within a mile of my house on my way home from work about two times a week or so. Same DTC, no actual performance issue that I notice, and it clears on key cycle.

First time to the dealer, they programmed the PCM and sent me on my way. Second time to the dealer, they claimed the clutch pressure sensor was bad and replaced it. I’m scheduled for my next appointment next week, as the issue is still happening. Given how quickly they claimed the sensor was bad, I’m wondering if they really took the time to go through all the changes to their workshop manual. Granted, being that they are sending out TSBs related to DTC P084B, I’m guessing Ford is seeing this happen a lot more recently and it isn’t just a sensor going bad. We’ll see what they “find” next week.

I had the Powertrain Manlfunction/Reduced power light come on one time. I took my truck in for two other recall issues. It's been there for a week, was told they need to put a starter in the truck to fix the malfunction light. Surprised by that. Starting the second week in the shop but no word as to what is going on. A little frustrated that I didn't get a loaner even after purchasing the extended warranty.
My Power Boost has been at the dealership for 21 days now. No word when the starter/generator part will arrive. The dealership did give me a loaner.

How much longer will those of us who are waiting for the "starter/alternator" part number ML3Z*11A213*B be without our trucks. My F150 PowerBoost has been in the shop for nearly a month now waiting for this part.

So ridiculous.
Ford has access to the component, obviously. But no desire to re-route any of them to the after-sale support.

It's shameful

This is the message I have gotten for about the last 10 months or so. It would warm me. Then I would drive anyway and shut it off when I stopped. When I would get back in and start, it would go away. Each time it happened, I had the wrench symbol illuminated on the dash.

I finally got tired of this happening and went to my dealer. They looked at it today. When I picked it up they told me they did 2 things. One, they looked at axel bolts and said they passed inspection. Great, no service needed.
2nd, they told me there is a TSB on my powertrain issue. They have to order parts. They are going to give me a new battery, a new starter and a new alternator! Wow, not bad for a TSB. They told me that it's an issue with the system between the starter and the alternator. That is killing the battery. We'll see how it turns out when they have the parts. All of this should be a recall. So, so many owners having their batteries drained and ruined. Costing Ford a mint. A 2024, same build as a 22 or to 23 is $16000 higher. That's nuts.

Also, I'm a little ticked off. The damn dealer did whatever they did to check my issue, but one part of it must have been turn on all the lights and drain his battery. Then give it back to me with a battery that is 35% charged!! Really@#$$ I'm calling them tomorrow to complain and rip em. I had not been getting any " turning off to save power" messages. That is, until I got back from the dealer and then I put it on my charger. Come on man!!
So I finally got an email about the Power Train malfunction. When I called dealer for appt, the check engine light disappeared and they could not see a code. They said ot needed SW update and issue has not come back but the battery draining message keeps appearing now.

Update on my end. In my case, it looks like I was just approved for them to rebuild my transmission. Parts are ordered, so it’ll be a week or more before I get it back and see if that finally took care of my issue.

Well I think they are doing something to my transmission as well but not sure. Only update I got today was broken bolts on the turbo so it’s delayed and may need a new turbo. Hoping to get a better update soon

Got my truck back on Friday after the fix for a bad CDF drum. Granted, I don’t see a new CDF drum in the long list of parts. Drove home from work yesterday, and the DTC comes back in just like before. They may have fixed something, but it wasn’t this issue. Just scheduled my 5th time back to a dealer, for this DTC. I’ve already had to pay my warranty deductible twice since the first dealer had to send me to a larger dealer after the 3rd attempt.
