Fuel gauge malfunction. When tank filled gauge reads empty. As fuel is used gauge operates more effectively. Service engine light periodically comes on due to "low Fuel level" $500 to $600 repair estimate
The low fuel light will stay on along with the engine light, no matter how much fuel is in the tank. Every once in awhile in a sharp turn or steep hill it will give me a reading of what is actually in the tank but only for a split second.
I pull into the gas station without the fuel light on, then I leave the gas pump after putting 20 gallons in it and the low fuel light is on as well as the check engine light. I was reading on line that GM is taking care of half the cost of the fuel pump/sending unit / sensor as it is all one part.
