It could be many things, but a tune up at 30K wouldn't have been one of them. Rather than going to the dealer, take the car to anationally recognized parts store and have the scan the computer. They will do it for free, and hopefully identify the problem. If the light is coming on, there is a trouble code being set.
Let me know what you find.
