When the fuel gauge falls below one-half tank, the gauge begins reading incorrectly...showing everything from a full tank to half tank.
I've had this issue for almost a year. But now the gauge will flop back and forth between full and empty.
The fuel gauge fluctuates wildly, though it rarely indicates a level below half a tank of fuel. At initial start up it appears to indicate an accurate fuel level but I'm still doubtful of its accuracy. The fuel used indicator seems to be more accurate for estimating what fuel level actually is
