I was driving on the expressway when my car started shaking and a malfunction message came on. My steering then started to steer only to the left and the car would not allow me to control the steering any longer. I hit the median wall, did a 360 and was facing the opposite direction of traffic. The door initially would not unlock to let me out. I kept trying in a panic and all of a sudden they unlocked for me to get out. My car was totaled out by my insurance company.
