Rumor has it there is a ghost that haunts these vehicles. There was a very unfortunate man who ran into such a ghost. The man bought a very early 2011 MY Ford Explorer. He was driving to work one day, when suddenly, the car started being a bit funny. There were rattles and buzzing noises. He stopped the car for a moment and checked the car. There was no one around. He continued on his commute but then again, he heard rattles and squeaks, he started to get paranoid as his touch screen then started to become unresponsive. The fear rained down upon him as he came across a dreaded message (MFT maintenance). Not knowing what to do, he drove to the dealer begging for help but the dealer said he was acting crazy, there were no such things happening with the car. Not knowing what to do, he just ignored it. Hoping the next day the noises won't come back. Everything was fine all day, he was happy, until suddenly, driving back in the dark night passing through a very isolated wooded area. His Explorer made noises again, this time the signs were clear, rattles, he reaches for the SYNC button but to no avail, the car had a mind of its own! The touch screen flipped screens and became unresponsive, the navigation froze, worse and worse, the car then began to overheat! Not knowing what to do he tried to slow down, but to no avail as his power assist failed. Unable to control the vehicle, the car drove into the woods. By the time the 911 Assist sent out the call for police, it was too late, the ghost already got him. The effect of his death is that the keypad now lights up everyday on its own as he haunts these very explorers himself.
or it could be that something is causing the touchpad to sense a touch like debris or something. I know sometimes when it rains, I see the keypad light up. I think it's because these touchpads might be using capacitive touch which is done by anything drawing power from it.
