Yes I received that yesterday, around 3:30pm EST. The next time I started the truck, later that evening, it was gone.
same! It did not re-appear when i started the truck again! This is the 4th Glitch since the latest ota update! 1. Trailer fault 2. Frunk adjar 3. Dash Brightness randomly changing and now 4. Powertrain Malfunction

hope today is less exciting! Hahaha

Consumers testing Ford software? Not so good. One of the solutions for odd faults has been to check the 12Vdc battery connections. Some have found a cable loose. Why do we need a "lucky to get" 3 year life 12Vdc battery instead of relying on low voltage tapped from the long life big battery?

12v is tapped from the traction pack to charge the 12v battery and run the 12v systems when the vehicle is on. You do not want this to keep running when the truck is off, due to the loss it creates; hence the 12v battery.

One solution (a good one in my book) is to upgrade your 12v battery to a lithium and be done with the issues for many years to come.

It’s very weird… since the over the air update last week I get random alerts. But shutting the truck off and Turing it back on has seemed to resolve the issues for now. Just a little annoying at the moment… Maybe the next update will address it.

I just had this happen this afternoon on my ‘23 Lariat ER which I’ve only had for 2 weeks. Check engine light came on with like 320 miles on the ODO. Truck otherwise drove fine. Drove to the dealer but the error cleared on the way there. I showed them the fault message from my phone. They took a quick look but couldn’t figure it out. They said bring it back tomorrow and they’ll give me a loaner since they expect it could take a while to troubleshoot all the various modules. I’ll report back what they say.

Mine did it tonight on my 2022 ER Lariat With only 498 miles on ODO. Parked it and then restarted and message gone. Maybe 12V was low and my 30mile drive home from work allowed It to charge 12V up???

Most of these messages are transients. Usually it’s best to just clear it and see if it comes back again before going to the dealer.

Ok thanks for the info. It was clear this morning. Also got an update overnight (only 3.5.5). Waiting on PAAK. Dealer has it to check it over this morning. I asked them to at least check the 12V battery. Thanks Mark!

UPDATE: dealer found a shift fault module issue. They had to order the part, it’s on back order. Ford would not allow them to release the truck to me. Could be a couple weeks for the part to come in.

I never received a clear update on the issue, but I got my truck back after 3 days. They claimed to have reprogrammed a module. It’s been 3 weeks since and there have been no further issues of any kind. Ford’s BEV team opened a case on it at my request. I didn’t get much more info on the issue from them, but they did comp me a Ford protection plan for 3 years, so I don’t need to worry about brake pads, wiper blades, or cabin air filters.

Well, I got 5 weeks of error free use. The same error returned today. I guess this error only occurs on holiday weekends.

I informed my service person at the dealer. But the error cleared itself the next morning and there have been no performance issues. I’m waiting for the dealer to call me back with their thoughts.
