2003 Nissan Pathfinder gas gauge is inaccurate to level indicated. On empty indicates full tank. Once filled it will remain accurate until 1/2 empty then begins to change levels each time vehicle is started. At times it reads full, other times 1/2 full and then jumping to full. Mechanic replaced fuel sender unit with Nissan parts from dealership. Problem remains. Presenting a po462 code both before and after replacing of float and sender unit.
Gas tank failure due to corrosion. After smelling a strong odor of gasoline I brought my 2003 Nissan Pathfinder to the dealer to have it checked, they discovered that the gas tank had rusted at the top of the tank underneath the rear seat allowing gasoline vapors to enter the interior as well as the exterior of the vehicle creating a potentially deadly situation. I was informed by the dealer that the gas tanks were on a national back order as none are available.
