2018 SUBARU WRX Structurebody Problems

IN JANUARY 2019 AROUND 10PM PST MY 2018 SUBARU WRX EXPERIENCED A SERIOUS MALFUNCTION. AT THE TIME OF THIS INCIENT I WAS IN A SUCLUDED, WOODED AREA WITHOUT CELLPHONE SERVICE, AS WELL AS BEING ATLEAST 30MINUTES TO THE NEAREST STORE. THIS COULD HAVE BEEN DEADLY. I WAS GOING DOWN A HILL AT 35MPH, IT WAS VERY RAINY AND DIFFICULT TO SEE. AT THE BOTTOM OF THIS HILL WAS A SHARP RIGHT TURN, AT THIS TIME THE SAFETY SYSTEM ACTIVED TAKING OVER ALL CONTROL OF THE VEHICLE. THIS CAUSED STEERING TO LOCK UP, TURNING TO THE FAR LEFT. AT THE RIGHT WAS A 15-20FOOT DROP INTO A LAKE. THE TURN I WAS SUPPOSED TO TAKE WAS A SHARP RIGHT. STILL UNABLE REGAIN CONTROL AND WAS DRIVING STRAIGHT TOWARDS THE FAST APPROACHING LAKE. SHORTLY BEFORE DROPOFF I WAS ABLE TO FORCE THE STERRING WHEEL TO THE RIGHT. BUT STEERING AGAIN LOCKED UP...
