2009 Ford Flex Fuel system Problems

“The car will cut off and think its out of gas. When my car has 1/8 it goes from 50 miles to 0. Then runs out of gas. If I fill up it will say 322 tip empty but only getting 225 out of fill tank of gas. I been having the issue since I purchased car in 2011. The fuel pump sending unit has to be replaced with jet pump.”

“As has been reported many time on here and in the FLEX forums, the vehicle will suddenly stall at a 1/4 tank of gas for no reason. I was traveling down the interstate at high way speed when the fuel gauge dropped to e and the miles to empty read 0. This has happened three times. I called one of my local dealers who insisted they have never heard of this problem and nothing was done. There advice was to not let the car get to a 1/4 of a tank. They have no fix for this dangerous problem.”

“The issue that has recently cropped up on our FLEX is the fuel meter will read sufficient fuel for approximately 50 miles and then, in a matter of miles, the tank seems to run dry/indicate no miles left. On this particular date I was driving the car it indicated 49 miles to empty. After 3 miles it ran out of gas. Fortunately I was on a side street and not the highway. This behavior could have been fatal if I was operating on a highway. I am not the only one having this issue. …”

“Car said '15 miles to empty' and gauge needle was just below a quarter, then needle dropped to empty and computer estimate went down to '3 miles to empty' within a mile..then shut down and limped off road. Left me stranded on the side of a busy city freeway in a very dangerous location, until I could get someone to bring gas to refuel. Repeated this the next time the gas was down to a quarter tank. I watched it carefully and saw it recalculate from approx 15 to empty, to 0 in less than 4 miles. Got to a gas station in time before the car shut off. …”

“Our 2009 Ford FLEX has shut off on 4 occasions while we were driving since nov. 2013 (11/29/2013, 12/18/2013, 12/28/2013, 4/15/2014). On 3 of the 4 occasions we were on interstate highways (495 in ma, 95 in ct, 81 in pa) which was scary and could have been deadly. On 2 of the 4 shut downs the car would not restart so we had to be towed. We noticed that once the car was taken off the flatbed, it started right up. That tells me that the gas must have moved to where it was needed. On each occurrence the gas gauge read half a tank or just slightly below. …”
