SEPTEMBER 18, 2011: WHILE EXITING AN INTERSTATE, I BEGAN TO GO AROUND THE CLOVERLEAF OF MY EXIT, LESS THAN 15 MPH, AND THE BACK END OF MY MUSTANG VERY QUICKLY FISHTAILED SPINNING ME ALL THE WAY AROUND. I ENDED UP FACING THE PEOPLE BEHIND ME, WHO FORTUNATELY WERE GOING AS SLOWLY AS I WAS. FORTUNATELY I WAS ABLE TO STOP JUST SHORT OF HITTING A CONCRETE BARRIER WALL. THERE WAS A VERY LIGHT RAIN, AND THE ROADS WERE WET. I HAVE ALL NEW TIRES. I'VE HAD THIS PROBLEM SINCE WE PURCHASED THE VEHICLE, AND HAVE FISH-TAILED BEFORE, BUT NEVER SPUN COMPLETELY AROUND. COMPLETELY TERRIFYING. *KB

POPPING/ METALLIC SOUND SIMILAR TO SOUND WHEN CRUNCHING A SODA CAN, A METALLIC POPPING SOUND FROM PASSENGER FLOOR BOARD AREA. DOES IT UNDER VARIOUS CONDITIONS, AND ONCE DID IT WHEN JUST GETTING INTO VEHICLE BEFORE STARTING, SEEMS TO BE LOAD RELATED AND SOME SORT OF STRESS RELIEF, BODY MOVEMENT SEEMS TO CAUSE IT. WAS CONFIRMED ON TEST DRIVE WITH A TECHNICIAN. THEY ATTEMPTED TO TIGHTEN FRONT SUSPENSION PARTS (TOURQUED ??) TRIED A POWER STEERING/RACK TSB WITH SOME SORT OF BRACKET ON RACK HOSES..... NO CHANGE, EXACT SAME NOISE, EVEN THOUGH FORD DOES NOT KNOW WHAT IT IS, THEY CLAIM IT IS NOT SAFETY RELATED..... POP CONTINUES .... VALUE OF CAR CONSIDERABLE LESSENED DUE TO NOISE ... SO ATTEMPTS TO SELL IT ARE IN VAIN... FORD HAS NOTHING BUT EXCUSES. *JB
WHILE DRIVING THE ACCELERATOR GOT STUCK, I APPLIED THE BRAKES WHEN THE CAR SPEND OUT OF CONTROL AND HIT THE CURVE, THE ACCELERATOR WAS RUNNING WHEN I TURNED THE CAR OFF. THIS CAUSE THE UPPER AND LOWER CONTROLS TO BREAK ALONG WITH THE DIFFERENTIAL AND BRAKES.
WHILE DRIVING 5-60 MPH STEERING WHEEL WOULD PULL TO THE RIGHT. DEALERSHIP WAS NOTIFIED, BUT DID NOT RESOLVE THE PROBLEM. *AK
