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.
check engine light is steady
check engine light comes on, stays on, then blinks
Actually a 2004 Vue, same problem. Guess Saturn issued a letter about being a know problem and will replace under 120,000miles/10 years
