WHILE DRIVING AT APPROXIMATELY 65 MPH ON A HIGHWAY, THE LOCKS ENGAGED, THE RADIO SHUT DOWN, POWER STEERING WAS LOST, AND THE VEHICLE SLOWED DOWN/BRAKED ON IT'S OWN. THANKFULLY WE WERE ABLE TO MOVE TO THE SIDE OF THE ROAD WITHOUT GETTING HIT. THE ONLY MESSAGE ON THE DASH WAS "SERVICE STABILITRACK." THE DEALER AND AN INDEPENDENT MECHANIC HAVE BEEN UNABLE TO REPLICATE THE ERROR MESSAGE. *TR
