why is gas gauge inaccurate, why is there not a recall on this known problem?

the fuel sender is most likely bad.it's the float/switch,and is part of the fuel pump module assembly,located in the fuel tank and must be replaced as a whole unit.all it's for is letting you know how much fuel you have in the tank.no recalls,no reported problems.some just go out on all makes, models.fords,chevys,toyotas,bmws.fuel tank will have to be removed,if fixin it,or just keep it full of gas,cause your pump is still working.
