The fuel sensor gauge does not accurately depict how much gasoline is in the tank. When I fill up the tank it remains on "e" and the low fuel indicator light is on. The gauge will fluctuate up and down and never go all the way to "f". I am very upset that this problem is so prevalent yet gm will only cover 50% of the expenses. It is unsafe to not know the correct amount of fuel in one's vehicle.
