    Have had cap replaced at least three times since we purchased auto. Started around 15,000. Dealership closed and any recalls, we are told need to go to a GM dealer or not covered even if other shops were certified through GM

    A Toy Story Sticker solved this one for me. I stuck it right over the indicator light!! THe darn thing comes on EVERY time that I am almost empty. As soon as I fill up, it may go off, it may not. Sometimes I only have to turn the car off, go outside and screw the cap on again. It's not a very smart car.

    The light came on signalling a Gas Cap issue. I bought a new one at the dealership where I bought the car new, and we still have the problem.
