So I have a 2011 Edge LTD FWD w\ 55000 miles ALSO with this issue.
Is this strictly an under warranty fix only?
I also have another issue w\ it that's driving me nuts. If you stay in park with the motor running for too long, the Collision Warning and Traction Control both throw fault errors on the left screen and become disabled. I'm surprised that's not some sort of recall in itself, since it disables the Traction Control.
The sad part is I'm a pretty loyal Ford fan (LOVE my 07 Fusion), but this vehicle, as much as I loved it in the beginning, is really wearing Ford's welcome in my driveway.
