WE WERE DRIVING ON THE HIGHWAY AND THE SPEEDOMETER JUMPED UP TO 120+ MPH. I WAS GOING 70MPH. THIS HAS HAPPENED A FEW TIMES. ITS VERY ANNOYING AND DANGEROUS NOT KNOWING HOW FAST YOU ARE GOING. PLEASE GET A RECALL OUT ON THIS PROBLEM. I HAVE READ QUITE A FEW STORIES ABOUT THIS HAPPENING AND GM NOT DOING ANYTHING.
