MY 23 YR OLD SON WAS TRAVELING FROM VENTURA, CA AT 75 MPH ON FWY 99 N BOUND IN THE MIDDLE LANE (OF 3) AT ABOUT 1 A.M. IN FRESNO, CA. JUST BEFORE ARRIVING AT HIS EXIT TO HWY 41 N, THE REAR END BEGAN TO SKID TO THE LEFT. DRIVER STEERED INTO THE SKID TO CORRECT WHILE STEPPING ON THE BRAKES TO REDUCE SPEED. SUDDENLY THE REAR END OF THE CAR WAS HURLED INTO THE AIR CAUSING THE ENTIRE VEHICLE TO GO AIRBORNE, CLEARING THE THIRD LANE (FAR RIGHT LANE) AND LANDING ON TOP OF ASPHALT BERM AND SOFT, SANDY EMBANKMENT RESULTING IN THE CAR ROLLING AND GOING AIRBORNE, BOUNCING OFF THE REAR END OF THE CAR AND GOING AIRBORNE YET A THIRD TIME LANDING UPSIDE DOWN ON THE SHOULDER OF THE FREEWAY WITH THE NOSE OF THE CAR EXTENDING INTO THE THIRD LANE. DRIVER RECEIVED MINOR INJURIES BUT CHP OFFICERS WERE ASTONISHED IT WAS NOT A FATALITY. CAR WAS TOTALED. TALKS WITH SATURN HEADQUARTERS HAS ONLY RESULTED IN DENIAL THAT THE SPINDLE COULD HAVE CAUSED THE ACCIDENT. THEY INSIST A TIRE BLOWOUT WAS MOST LIKELY THE CAUSE. PERSONAL INVESTIGATION REVEALED THERE WAS NO BLOWOUT. EVIDENCE POINTS TOWARD THE SPINDLE BREAKING ALLOWING THE WHEEL ASSEMBLY TO FOLD DOWN UNDER THE CAR CAUSING IT TO SKID TO THE LEFT. THE APPLICATION OF BRAKES BROUGHT THE FRONT END OF THE CAR DOWN ENOUGH TO ALLOW THE WHEEL ASSEMBLY TO CATCH THE FRAME ASSEMBLY AND PITCH THE CAR INTO THE AIR WHILE TEARING OUT THE ENTIRE REAR WHEEL WELL ASSEMBLY. PARTS OF THE WHEEL ASSEMBLY WERE FOUND 40 FEET BEFORE THE IMPACT OF THE CAR ON THE DRIV
