ON 08/13/2011, I WAS TRAVELING ON NORTHBOUND I-95 WHEN A LOUD BOOM OCCURED AND THE CAR BEGAN LURCHING OUT OF CONTROL BRINGING THE TIRES OFF OF THE GROUND. I MANAGED TO GET THE VEHICLE UNDER CONTROL AND DISCOVERED THE BOLTS ON THE DRIVESHAFT HAD LOOSENED AND FELL OFF, RESULTING IN THE DRIVESHAFT STRIKING THE PAVEMENT "LIKE A CATAPULT" AND OBSERVED THE DRIVESHAFT LAYING UNDER THE CAR, DISABILING THE VEHICLE IN TRAFFIC WITH NO CONTROL. HAD MY INFANT AND TWO OTHER CHILDREN IN THE CAR AND THEY WERE FLUNG ABOUT DURING THE INCIDENT. THIS IS THE SECOND TIME THE BOLTS ON THE DRIVESHAFT HAVE LOOSENED AND FALLEN OFF, RENDERING THE VEHICLE INOPERABALE AND CAUSING THE VEHICLE TO LOSE CONTROL WHEN THE DRIVESHAFT STRIKES THE PAVEMENT. THE LAST ONE (04/10) OCCURED AT A LOW SPEED BUT STILL CAUSED THE TIRES TO LEAVE THE GROUND. SATURN HAS ISSUED A TBI FOR THE BOLTS BUT HAS NOT FIXED THE PROBLEM AS EVIDENCED BY THIS MOST RECENT INCIDENT. *TR
