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.
My 07 9-7x always reads empty. I've only had it a few months and its been like that since I bought it used.

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.

when tank is half full, the light comes on and registered empty. This has happened twice straight
Fuel gauge reads empty when tank is full. Engine light comes on as it does this.
I changed the fuel level sender (involves dropping the fuel tank) with a new sender and the problem was solved.
