Looks like I was not on the latest update. Did the USB update last night and will report back if issue continue. FYI update took about 15 min or so to apply on my 2020.
I have a 2020 Expedition Max and have the exact same symptoms. The first time it occurred was about Oct 10th, but a restart resolved it. Since Oct 21st or so we have to do the Power + Forward hold down. It happens randomly, for some reason more for my wife...
Mine is on the auto update via...
Did anyone find a resolution ? On my 2020 Limited RWD, have this same issue of a high pitched whine only on acceleration after 45mph or more. RPMs are in the 1500-2500 usually.
