My fuel gauge has gone completely out of whack. I filled up 6 days ago, and over the course of three days (at least 200 miles), the fuel gauge remained pinned at the highest reading - just above F. I knew this was incorrect, as I've previously had an issue (off and on) where the reading would actually INCREASE as I drove. http://fordfusionhyb...-gauge-reading/As described in that thread, the dealer did flash some software, but the problem persisted intermittently (the worst kind of problem...). At times, it will stay "normal", but will freak out on occasion, and after a few days will return to normal.
Anyhow, last Friday, I parked it at home with the gauge still above F. Monday, I started it up after not driving it over the weekend, and it showed about three quarters full. I think it should have been around half by this time, but no matter - as I drove to work, it began decreasing as I watched! After about 20 miles, it was on E - the low fuel warning popped up and the icon turned yellow, and a few minutes later - red! The miles to empty had dropped all the way to 0, and then just ---. And then later in the day, it's showing a nearly full tank. The fluctuations are very disconcerting (especially when the car warns me I'm running out of gas), but I've learned to deal with it.
I haven't seen anyone else report such an issue, and I have no interest in visiting a dealer just to have a mechanic "guess" at what might be wrong. Maybe someone here has an idea, or maybe even a knowledgeable Ford technician might read this and chime in... At this point, I'm used to just tracking the miles driven and gallons used for each tank, and refueling when I'm around 500-600 miles or about 11 gallons used, give or take.
