The contact then coasted over to the emergency lane and there were no warning lights illuminated. The vehicle restarted; however, the failure recurred multiple times. The vehicle was taken to the dealer for diagnostic testing. The technician diagnosed that the side charge air hose into the throttle actuator was torn and caused the loss of hose pressure. Both the left and right hose needed to be replaced. The vehicle was not repaired. …”
