LOSS OF STEERING CONTROL! 11 May 2017, driving highway 5 to LA, speed control on at 72 MPH. Suddenly car veered to the left, all over both lanes. I was unable to get the car to drive straight. The car continued to swerve left then into the right lane causing it to spin backwards off the highway and into the dirt. I still was unable to stop the car as it continued to roll over. I was upside down and trapped inside the car. COMPLAINT WAS FILED IN 2017.
