Check engine light came on with Check Gas Cap alert. I noticed it came on when it reached 1/4. I would unscrew it and then tighten it again and light would go out. It doesn't always work.
Actually a 2004 Vue, same problem. Guess Saturn issued a letter about being a know problem and will replace under 120,000miles/10 years
