Check Engine Light came on this afternoon. Called OnStar and they sent me an email with P06DC and P24A5.
About three weeks ago OnStar told me that I had P06DC but had no check engine light. Same thing about six months ago.
I‘m bone stock and 106,000 miles on the odometer.
Happened to be near my dealership so I stopped in. But my service advisor was off today. I went on my way and the check engine light cleared after about 50 miles.
Searched here and google. But could not find any correlation with those codes.
Anyone have any ideas?
