MY DAUGHTER WAS DRIVING MY 2000 MERCURY SABLE AROUND A CURVE TO THE LEFT WHEN THE REAR OF THE VEHICLE BEGAN TO SLIDE TO THE LEFT CAUSING HER TO LOOSE CONTROL AND STRIKE 2 GUARD RAILS,2 VEHICLES TRAVELING IN THE OPPOSITE DIRECTION AND THEN HEAD-ON INTO A STONE RETAINING WALL. VEHICLE WAS SEVERELY DAMAGE AND MY DAUGHTER SUFFERED A MINOR HEAD INJURY. THE AIRBAGS DID NOT DEPLOY EVEN AFTER STRIKING THE WALL HEAD-ON. WE ARE CONCERNED THAT THE REAR COIL SPRINGS WERE DEFECTIVE, RUSTED AND MAY HAVE CAUSE HER TO LOOSE CONTROL AND THE REAR-END OF THE VEHICLE TO SLIDE TO THE LEFT. 1 WEEK PRIOR TO VEHICLE CRASH/INCIDENT, THE REAR END OF THE VEHICLE SLID TO THE LEFT ON DRY PAVEMENT WHILE TURNING TO THE RIGHT. VEHICLE TIRES WERE FAIRLY NEW AND IN GOOD CONDITION. PLEASE REVIEW THE 2000 MERCURY SABLE FOR DEFECTS IN THE REAR COIL SPRINGS AND THE AIRBAG DEPLOYMENT FAILURE. *TR
