Default It’s the TCM!

To everyone here, I had the same problems, same codes. My traction control, power steering, and parking assist lights where one. Car ran fine when warm, but not too warm. Wouldn’t start when cold. Engine sounded terrible, intake problems, rough idle. 2012 Chevy Cruze. Intermittent problems, changed out EVERYTHING, literally. Negative battery cable, PCV, intake housing, spark plugs, I changed it all. It was the TCM all along. Replaced and programmed and haven’t had a problem since.
