Supposedly they have checked all of the harnesses especially the on behind the wheel liner for a short and haven’t found anything

It’s a 2020 Silverado rst 3.0 diesel. The harness they are referring to is the main engine harness and say they have to lift the entire body from the frame to change it out most of the money is for labor they charge 270 per hour

Mine is doing the same thing as Montana Steve did they figure it out my dealership can’t figure it out after three months they say they need to replace the main harness and that’s a $10000 fix and isn’t under warranty
