I had the speedometer problem last week where it just sticks when you are driving. It stopped at 57 MPH and would not move when I speed up or slowed down. Finaly I stopped and it went down to the bottom of the gauge. When I shut down and restarted it went back to normal. I did a thread search but didn't find what I was looking for. I know some of you have had this problem. Did Chevy put out a bulletin on it? Also did it keep getting worse untill it quit completely or did the problem stay random? I am asking because I am now on my extended warrenty and if you take it in and they don't find a problem they charge you. It is working OK now so I don't think they will do anything about it.
