Wanted to thank you for a article I read about the woman that had the service light on in her car and the dealer said it was the car's gas cap. My wife had her service light come on and started asking me what it could be. After reading your article I went out and checked the gas cap, sure enough that was the problem.

Saturn may want to list in the owners manual simple checks the owner can do before taking the car in for this type of indication.

Anyway, I wanted to thank you for posting your e-mail correspondence.

My 2005 L200 had the same light come on.  I returned to the dealer three time and after some discussion they did tell me that it was the main computor and that they would replace it.  This was done under extended warranty that I purchased. 100.00 deductable every visit.
