While driving to work this morning, my check engine light came on. Car is driving fine, no issues that I could see. I took it and had it scanned. He said there were several codes but the two main ones that he said it kept coming back to was P0CC2 and P0AC4. VERY little info online about them or what could be causing them or and idea on what to do to fix them. I drive a 2013 Malibu Eco with 80k miles on it. Keep it serviced and whatnot. Like I said, no issues. A few weeks ago, I went out of town and left car at home for 10 days. When I got home, it was completely dead. Had to be jumped off. No issues other than that. Please help!
