Similar happening to mine. Turned it on (guage in Enlighten mode) frove about 4 miles. 00.0 on the mpg redaout, the ACC, PWR, and instant mpg needles either jumped around sporadically or never moved. Got home turned the car off and on a couple times and all was ok for about a week. Did the same thing. This time I did not turn off but drove to dealer and took service guy for a ride to show him. He e-mailed Ford hot-line and was told (he said) that they never heard of this. No correction was offered (ok, this may be all new to them). This all happened first week or so in Nov. All has been ok since then. Although intantant mpg has a couple of times started out at 99.9 and worked its way down whereas all the other times mpg starts at 00.0 (if I had reset it) or at the last mpg when I last parked it.
