My 2011 CTS4 almost didn't start the other day so I put it on a scanner and it came up with a misfire in cylinder 6. Took it to the dealership to get fixed. It has 85k on it. They changed the plugs and coil packs and gave it a tune-up. Got the car back and drove it less than 50 miles. Last night on my way home, alarm bells started sounding, engine light came on. Car went in to limp mode and it said engine was over heating. (It was 29°f out)
We pulled over for a minute. Shut it down. Waited turned it back on and drove the last mile home in limp mode watching temp gauge. Anyone have a clue to what's going on?
