I have a 2007 outlook xe. I bought it 2 months ago and already had the transmission changed. Everything has been going fine and I have started trusting it. My check engine light is on now. The car is running fine...not one problem. We changed out the gas cap and it shut off on it's own. A few days later it came back on again. It runs fine. I don't have any codes to give y'all. Has this happened to anyone?
