I was driving my Mitsubishi across the university bridge on 7-28-2017 and suddenly the transmission went out and I was stuck and had no power of movement,my wife and 3 y. O. Child were passengers in the car,luckily the state patrol came and assisted us. The dealer told us that this car was mechanically sound and had no problems or issues. They lied to us and by doing so they put our lives in danger. The drivers side air bag was also missing when we purchased the car.
