Problems with 2014 Ford Fusion STEERING

I purchased a 2014 ford fusion on march 24, 2014. my son was driving on the expressway and the steering wheel would not turn for him to change lanes to exit. the next day(may 6th) he took the car back to the dealer and they kept the car for two days. again, he was driving on the expressway from the dealer (may 8th) and the steering froze and he had to maneuver the car to exit the expressway. the next day he took the car back to the dealer. the service department (after diagnosing the situation for three days) stated that ford changed from hydraulic module to an electrical module and the part is on backorder. i was given a loaner on that day and today is friday, may 30th and i do not have back my car. i am making payments on a new car with steering problems and my concern is will the car's steering problem be resolved with the replacement module. i am concerned about safety when highway or expressway driving. there are enough distractions with other drivers (texting, eating, talking on the phone, etc.) without having to be concerned whether the steering wheel will lock up and cause an accident and injure my son or others. *tr

I was driving home on a 2 lane hwy. and message came "steering fault service now" i called the dealership from the car and was told if the car wasn't doing anything abnormal, keep driving and bring it in monday. i arrived home safely turned off car and took pkgs. in the house. i came back out and started the car right away and the message was "loss of steering" and indeed no power steering. i called ford and they sent a tow truck driver and we took it to the dealership. it hasn't been serviced yet. *tr
