1999: “Drivers side gas tank is leaking with strong gas fumes coming from under car sitting still. Leak is at the bottom sending unit on the left plastic tank under the passenger seat behind the driver. I isolated the leak to where the wires plug to the tank gauge sending unit. This is obviously a very dangerous condition that should not occur ever in normal operating of the car. This car has not been abused or wrecked that I know about so, it is a manufacturer defect. …”
