WHILE MAKING A LEFT TURN ONTO ANOTHER STREET AT APPROXIMATELY 12 MPH, THE LEFT REAR BALL JOINT PULLED COMPLETELY UNSEATED. THIS CAUSED THE WHEEL TO NO LONGER SPIN AND PUSHED THE TOP AGAINST THE FRAME CAUSING DAMAGE TO THE FOLLOWING: UPPER CONTROL ARM, UPPER PIVOT BUSHING, AND KNUCKLE ON THE LEFT REAR WHEEL. I DID HAVE THE BALL JOINT REPLACED AND CURRENTLY AM IN NEED OF REPLACING THE BUSHING AND KNUCKLE. ALL IN ALL, THESE REPAIRS WILL HAVE COST ME: BALL JOINT REPLACEMENT AND LABOR APPROXIMATELY 267.00, BUSHING AND KNUCKLE 165.00, AND UPPER CONTROL ARM 65.00, PLUS TOOL RENTALS. LUCKILY I WAS NOT DRIVING ANY FASTER AT THE TIME OF INCIDENT, BUT STILL IT CAUSED LOSS OF FUNCTION AND STEERING BASED ON THAT. THERE IS A RECALL IN CANADA FOR THIS ISSUE BUT HAS NOT BEEN ISSUED IN THE U.S. I'M SERIOUSLY CONSIDERING A LAWSUIT AGAINST GM FOR THIS AS IT IS USED NOT ONLY AS MY WORKING VEHICLE FOR MY JOB, BUT ALSO TO TRANSPORT MY FAMILY.
