So I got my new C-Max SEL a week and a half ago. About 4 days after I got it, the check engine light came on out of nowhere. Nothing appeared to be wrong, but the light wouldn't go off. I took it to the dealer a week ago today. They cleared everything and could not fight a problem. I went out earlier to grab some coffee and the light came on again, out of nowhere. So now I'm back to the dealer AGAIN. I haven't owned this car two weeks. What gives? Anyone have similar problems?
