Transmission slips out of gear while driving and sometimes while stopped. Rear backup camera comes on while driving forward at highway speeds. Ford has issued TSB but my dealer was unaware of it and did not repair until I took them a copy of the TSB 10-21-2. Very dangerous especially when pulling out into traffic. Somebody is going to get hurt. I found info on TSB through owner message boards so it's not an isolated problem.
