CASUAL DRIVER. NOTICED ACCELERATION AND COASTING/ROLLING WERE SLUGGISH. MECHANIC NOTED BRAKE AREA TEMP ON FRONT DRIVER'S SIDE WAS OVER 400 DEGREES. THE BRAKES ON THAT WHEEL WOULD NOT RELEASE COMPLETELY AND CAUSED CONTINUOUS FRICTION PRODUCING OVERHEATING. (I NOTICED I AM NOT THE ONLY ONE TO SUBMIT THIS BRAKE PROBLEM TO THIS BOARD. ) THE MECHANIC REPLACED THE TOTAL FRONT BRAKES AND MASTER CYLINDER SYSTEM. COST OVER $1100 TO DO THIS BACK IN 2013. IT IS NOW JAN 2021 AND I STILL HAVE LESS THAN 50,000 MILES ON MY BABY MUSTANG.

GAS PEDAL GOT CAUGHT ON A PIECE OF CARPET WHICH CAUSED MY CAR TO ENTER INTO AN INTERSECTION ON A RED LIGHT AND CAUSED ME TO HAVE AN ACCIDENT. WHICH THEN MADE MY INSURANCE JUMP. I REMEMBER THIS DAY VERY WELL IT WAS THE DAY BEFORE MY BIRTHDAY I CAME UP TO THE RED LIGHT AND STOPPED THE CAR SEEM TO WANT TO KEEP MOVING FORWARD AS I PUT MY FOOT ON THE BREAK IT WAS STILL A RED LIGHT MY CAR WAS MOVING FORWARD CARS WERE BEEPING AT ME AS I KEPT INCHING INTO THE MIDDLE OF THE STREET MY CAR WAS HIT IN THE REAR PASSENGER SIDE BY ANOTHER MUSTANG. I EXPLAIN TO THE POLICE OFFICER THAT WHAT SEEM TO HAPPEN WAS MY CARPET SEEM TO HAVE GOTTEN CAUGHT ON THE GAS PEDAL. AFTER LATER LEARNING THAT THERE WAS A RECALL FOR THAT PARTICULAR PROBLEM IT WASN'T RE CALLING UNDER MY VIN. TO THIS DAY I HAVE AN ACCIDENT MARK ON MY INSURANCE WHICH MADE MY BILL GO UP I DON'T THINK THAT THIS IS FAIR CONSIDERING THAT IT WAS NOT MY FAULT I TRIED SHOWING THE INSURANCE COMPANY THAT THERE WAS A RECALL BUT IT WASN'T RECALLING UNDER MY VIN NUMBER

THE SPARK PLUGS HAVE A TENDENCY TO BLOW OUT. AN EXPLOSION MAKES THE PLUG STRIP THE THREADS AND DO DAMAGE TO THE HEAD. THERE IS ALSO POTENTIAL FOR FIRE AS FUEL VAPOR IS THEN RELEASE DIRECTLY INTO THE ENGINE COMPARTMENT.

FOR AT LEAST 5 YEARS THE CONVERTIBLE TOP LEAKS WATER INTO THE BACK OF THE CAR WHEN THE TOP FOLDS DOWN INTO THE BACK OF THE CAR, THEN THIS WATER LEAKS ONTO THE BACK FLOOR BOARDS. AFRAID IT IS GOING TO ROT OUT THE FLOOR BOARDS. THIS NEEDS TO BE TAKEN CARE OF. I KNOW OF MANY FORD MUSTANGS THAT DO THIS.

PASSENGER SIDE FRONT SEAT BELT RETRACTS ONLY AND WILL NOT EXTEND, SO THEREFORE IS NON-FUNCTIONAL. THIS IS NOT A CASE OF TWISTED BELT, AS WE HAVE ACCESSED THE PART AND ENSURED "FLAT" WIND. MY SON JUST BOUGHT CAR. PRIOR OWNER SAYS IT NEVER WORKED FOR SEVERAL YEARS. DRIVER'S SIDE SEAT BELT IS ALSO BARELY FUNCTIONAL. BOTH PRESENT MAJOR SAFETY HAZARDS TO OCCUPANTS. LOOKING ON-LINE THIS SEEMS TO BE A WELL KNOWN PROBLEM WITH THE MANUFACTURER'S DESIGN WHICH SHOULD BE CORRECTED. *TR

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.

IN 2004 MY MOM BOUGHT A NEW 2004 FORD MUSTANG WITH THE 3.9 V-6 MOTOR AND WITHIN A COUPLE OF MONTHS IT STARTED TICKING REAL LOUD WHEN YOU FIRST START IT UP. COME TO FIND OUT IT WAS A PASSENGER SIDE EXHAUST LEAK THAT JUST GOT WORSE, AND AT THE SAME TIME HER ENGINE STARTED MAKING LOUD CHIRPING AND CRAZY NOISES TO FIND OUT IT WAS THE CAM POSITIONING SENSOR THAT WENT OUT. WELL SHE PAID ABOUT $550.00 TO GET THE SENSOR FIXED BUT SHE COULDN'T AFFORD THE EXHAUST TO.SO STILL TO THIS DAY SHE DRIVES HER NICE LOOKING MUSTANG CAREFULLY AROUND TOWN THAT SOUNDS LIKE ITS READY TO DIE, AND I WOULDN'T TRUST DRIVING THAT THING 10 MILES OUT OF TOWN. IT MIGHT NOT BE AN EYE SORE BUT IT SURE IS AN EAR SORE, AND IS STRESSING YEARS OFF MY OLD BROKE MOTHERS LIFE. WE'VE ALWAYS BEEN A FORD FAMILY AND MY DAD RETIRED FROM FORD PROVING GROUNDS. BUT THAT IS THE SORRIEST FORD WE'VE EVER SEEN.OH YEAH, PLUS THE AUTOMATIC TRANSMISSION NEVER SHIFTED RIGHT FROM DAY 1, AND SHE HAS HAD TO REPLACE THE ALTERNATOR, BATTERY ,A PULLEY, THE SERPENTINE BELT ETC.AND IT HAS A LOT OF RATTLES AND ROAD NOISE,AND IT JUST BARELY MADE 60,000 MILES. *TR
