Driving back home on the highway my steering wheel locked up while driving 75 mph in the middle lane of the highway. Something popped up and said steering wheel unavailable. Luckily no other cars were around I tried to pull the wheel to the right to get off the highway just it case it turned off, but I was pulling to left and I almost hit the wall in the median. The steering wheel clicked in and I snatch the wheel to the right! It could have been in fatal accident had I hit the wall. Cars coming down the fast lane would not have seen me crashed into the wall, because I was in a blind spot curve. It would have been fatal! and what if my daughter was in the car! I am scared for my safety and my daughters safety while riding in this car!! It caused me to go into a complete panic attack
