I called ford service complaint hot line and they took my complaint. they indicated they were going to just send it to the dealership
I also looked at the local dealership site to see if there was a survey link and wound up on a chat with their internet response team. I asked them for a link to rate the 22 feb service response I got and they took my info.....a few minutes later...service manager emails me and says they will find an appt.
so maybe will not have to go out of state after all.
as crazy sensitive as the electrical system is could it just be a bad voltage sensor, no clue if that even exist anymore though.
also wondering if the voltage reading is a phantom reading, have you tried to start and disconnect both batteries and then see what the alt output is?
Grabbing at straws here but I feel your pain.
I brought it in to a PA dealership. I live in nyc.
they concluded it was an open circuit (somewhere under pax battery). Message and error is gone....but...I’ve had it for a few days and my battery voltages are runnning 14.8 to 14.9 which seem high to me. Will probally have to bring it in again.

Is this looking like a harness problem again?

Those voltages do appear a bit high. What is the resting voltage of your batteries? I've noticed 14.4-14.6 when my batteries are charging up. Maybe it's possible your batteries are a bit drained and the alternator is outputting a bit more voltage to quick charge them?
I do mostly short trips during the week and on the weekends take a little longer drives so I'll precharg the batteries on a trickle charger then monitor them over the weekend.
my concern is I read that the PCM varies the charge rate depending on the battery state of charge and in the past I verifed the charge rate varied...meaning....after crank up the voltage was mid 14's, but once the batteries recharge (5 to 10 minutes), the voltages dropped to low 14's.
I also know that if I put a surge protector across the battery terminals, indicated running charge voltages never go above 14.5, so that tells me that the 14.8/14.9 stuff that is going on are voltage spikes.
