When the fuel tank is filled with 1/4 tank or below and is parked on a slight decline, the fuel gauge will drop below empty and the low fuel light will illuminate. Sometimes the vehicle will have a hard time starting or will not start at all until the vehicle is pushed onto a more level surface. It has been into the dealer 5 times for this condition and the problem continues.
