    I just got it serviced today because of the engine light. It's a little over 24,000 miles now. I've had this problem about 3 or 4 times since 5,000 miles. The mechanic said that the filter on the gas cap was dirty. It's been a pain in the ass. It gets a little sluggish also whenever the light is on.

    Check engine light comes on sporadically, always at speeds over 60mph. Not yet gas cap??

    Gas cap sounds like it locks, but you can pull it right off. Check engine light is constantly coming on. It's a pain in the butt. Have contacted OnStar with problem and have talked with their technicians about the problem. Last time we talked with them, we were given a document ID# and were told that it was an issue that needs to be taken up with our non-existent dealer. Will be making an appointment with dealership AFTER my company leaves!
