We had some weird problems with our MFT last week as well. I did the performance upgrade the week before, which went fine. The system ran for a week or so with no issues.
Last week we were going out and I hopped in the truck....normally all three screen light up when you open the door. The two in the console did, but the big eight didn't.
I put the key in the ignition and fired her up. The two console screens came up but the eight remained black. So turned the truck off and opened the door. The two console screens went out, but the big eight came on and stayed up (with the key OUT of the ignition).
I repeated the item several times to no avail - the big eight didn't come back on when the key was is in the ignition, but would come on when the key was out and the door was opened and closed.
The other anomaly is that the Sync did not work (when I pushed it, the system did nothing) and the backup cam didn't work either.
We did bring it to the dealer, but they were closing so we made an appointment for later on in the week. As a last resort, I did a "hard reset" (undid and removed the positive battery cable, waited a minute and then put the cable back on). When I tried it again, I thought the same problem was going to happen. But then the Sync logo came on the big eight and there was a message that said "System cleanup, please wait" or something to that effect.
When it was done doing whatever it did to clean up all systems came back to normal. We haven't had a repeat performance since then.
I guess it's what to expect from a system that is software-based.
