I am 1/2 way thru a 2 hour trip driving on interstate 75 in Florida doing about 75mph when all of the sudden I couldn't steer, had no dash lights with the exception of the radio plus the bluetooth still worked and braking was very difficult. I couldn't accelerate, nothing happened when I pushed the gas pedal. Neither turn signal worked but the emergency flashers did. Managed to get it on side of highway but then it got interesting; couldn't shift out of drive and couldn't turn the car off; I could turn the key but nothing happened. After sitting on the side of the road with my foot on the brake pedal for 30 minutes I tried turning the car off again and it magically worked. I sat there for about 10 minutes and thought I would turn the car on and see what happened; turned the key and it fired up like normal and everything was working just fine. Dealer says they have never heard of anything like this happening.
