Hello, just found this forum and this is my first post so hope I chose the correct one to post my question in. I have a 2016 GMC Acadia and I have had this issue happen twice and want to see if anyone has also experienced this. Both times I was stopped at a red light and noticed a brief rough idle when the light turns green and I begin to go the “Stabilitrack Off” light and ”Check Engine” light comes on. Today the ”Service Stabilitrak“ also come on. Also, on both times I noticed after the lights go off that the rpm will go up high to at least to the 3 in between shifts. When I turn the engine off and crank it again it is fine. The first time it happen was just before Christmas and then again today. I’m curious to see if anyone else has had this happen and what was causing it. It’s making me sick to know I may have to take it to the dealer and who knows how much this could costs me. Thank you.
