My 2007 Jeep Compass check engine light come on then goes off. I have notice when I have to use the heater in the morning and the AC in the evening for a few days the check engine light will come on for a week or so. Also, My husband uses the cruise control and I don't. It will come on when he is driving it also. But it runs fine. So, I'm still running it and it has about 50,000 more miles on it since it started.
