A little background information. There is a known issue with the sensor on the gas tank of the G5 and the gas gauge makes the driver think it's using more gas then it really is. Up until this point I don't believe I have had this problem. What my car is doing is... When I fill the tank the pump stops at the start of the last notch rather then at the end of the notch where any car would fill to. Any ideas? It has happened the last 2 times I have filled it.
