On Thursday July 22 when I went to go start my car my vehicle would not drive forward, it would only roll forward. The car dash stated it was because of the "stabilitrack" and the transmission light was also on. The car was towed and supposedly fixed. On Thursday July 30, I was driving on a major highway at 70mph about to turn off onto a ramp where my car stops driving in heavy traffic. The car was able to roll into the emergency lane. Again, the transmission light came on and "stabilitrack" came up on the dashboard. The car has been there for 4 working days and they still have not fixed it. They think it is a bad switch or wire in the transmission. This concerns me because it may happen again. If I did not recognize what was going on and thought quickly, I could have cause a major accident because of the speed the cars were driving on the interstate.
