I MERGED ON TO THE FREEWAY ON RAMP INCREASING MY SPEED AS NORMAL. WITNESS STATES I WAS DRIVING IN THE CENTER OF THE STREET. ALL OF A SUDDEN MY VEHICLE LOST TRACTION AND STARTING SWERVING RIGHT AND LEFT AS IF A TIRE HAD BLOWN OUT. I TRY TO GET CONTROL OF THE VEHICLE BY LETTING OFF OF THE GAS AND STEERING STRAIGHT WHEN MY STEERING WHEEL LOCKED UP AND I WAS UNABLE TO MOVE THE STEERING WHEEL. I TRIED TO HOLD THE STEERING WHEEL STRAIGHT AS MY CAR VEERED OFF THE SIDE OF THE FREEWAY AND ROLLED OVER ONCE. I HAD THREE SMALL CHILDREN IN THE BACK SEAT BUCKLED AND SECURED AND MY CAR LANDED ON ITS TIRES. NO AIRBAGS DEPLOYED DURING THE ROLLOVER ACCIDENT AND I WAS UNABLE TO GET CONTROL OF THE VEHICLE DUE TO THE STEERING WHEEL BEING LOCKED AND THE SUDDEN LOSS OF CONTROL. ONCE I HAD PULLED MY CHILDREN OUT OF THE VEHICLE I NOTICED NON OF THE TIRES HAD BLOWN BUT MY ENTIRE FRONT END OF MY VEHICLE WAS DESTROYED. PRIOR TO THE ACCIDENT THERE HAD BEEN NO NOTICEABLE PROBLEMS WITH THE CAR AND THE ACCIDENT WAS DUE TO A MECHANICAL ISSUE OR FAULTY ASSEMBLY OF THE VEHICLE. *TR
