My truck did this 2 days in a row. After the second time it was throwing a transmission error code. Dealer had for 2 weeks. They called today and said they replaced some computer control board and appears to be working now. They are delivery to me today. We will see if issue is resolved going forward.

I sure hope that solves your particular problem.

I had a new Chevy a few years back that did the same thing. Dead to the world. After being at the dealer for a week they could not find anything wrong but decided to put a new battery in it and after that no problem so there is hope that the battery is the problem.

Haven’t had my new F-150 for more than two weeks and experiencing the “phantom battery drain”. Anyone else having this dead battery issue? I’m hoping someone in my remote Alaskan town can help solve the issue.

Got my truck buck from the dealer yesterday after they had it for 2 weeks for testing for the Phantom Battery issue, and was throwing codes for a Powertrain Malfunction. Dealer ended up replacing the PCM. Per the service report part replaced was "ML3Z 12A650 GVB". Will report back if I still have issue.

I was having the same battery issues and I brought it to the dealership and they reflashed the heated mirrors/ tow module and now my windows don’t go up with one touch anymore they go down fine just have to hold the switch to go back up annoying

Read the manual about how to reset the one touch. Looks really easy.

This is because they forgot to restore your vehicles settings after the reflash. Same thing happened to me and my power folding mirrors were turned off. Luckily he still had my settings in his tool and restored everything.

Maybe we should enlighten this sharp reporter about the rust issue as well?
What is the rust issue? Unfortunately I’ve experienced the battery drain as well so I can’t wait to hear what this is.
