I'm having the same issue. I have a 2007 Chevy Silverado I had the motor rebuilt and 2015 because I lost compression on the number 7 cylinder. Now I'm having the same issue with the Stabilitrak light coming on and the rough idle. I spent over $3,000 having the motor rebuilt and now it's rough idling the Stabilitrak lights coming on and I'm here in a little ticking noise. If I have to rebuild this motor again I'm not going to be very happy. GM knows about this issue they need to do something about it. I'm all game for the lawsuit. Does anyone know a lawyer that would be good for this kind of suit?
