I had a little bit of engine trouble, as in my Check Engine Maintenance light is on. I called the Chevy dealer and they can't get me in for another two weeks. Bummer. I found a company called YourMechanic who does house calls. They came out and checked the codes. Coolant Fan issue. The guy said there was a loose plug, he plugged it in and the light went out. I sort of think he might have just cleared the code, but what do I know.
