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
CAR WAS PARKED ON HILL WHILE IDLING WITH PARKING BRAKE ON, WHEN THE CAR ROLLED DOWN THE HILL, RESULTING IN OVER $5,000.00 IN DAMAGES. THE BREAK HANDLE WAS STILL IN THE UP POSITION. *TR
A FEW DAYS PRIOR MY CAR MADE A SQUEALING NOISE WHEN I STOPPED. ON DEC 25, 2006 I WAS TRAVELING DOWN A RESIDENTIAL STREET WHEN MY AXLES SHIFT AND MY CAR TIRES LOCKED UP, IT WAS APPROXIMATELY 1/8 MILE FROM MY HOME. THE STEERING WHEEL WAS SHIFTED APPROXIMATELY 90 DEGREES. *JB

DT: THE CONSUMER STATES THAT 2004 FORD MUSTANG WAS HAVING MECHANICAL PROBLEMS. THE TRANSMISSION FLUID WAS GUSHING OUT AND THE VEHICLE WAS TAKEN TO A DEALERSHIP FOR REPAIRS. THE DEALERSHIP FIXED THE TRANSMISSION FLUID PROBLEM. THE NEXT PROBLEM WAS OIL LEAKING. THE VEHICLE HAS BEEN IN THE DEALERSHIP TWICE FOR REPAIRS AND IT WAS STILL LEAKING OIL. THE OWNER CONTACTED FORD FOR HELP. FORD HAD THE CAR TAKEN TO THE DEALERSHIP THAT FORD RECOMMENDED. THE PROBLEM IS STILL NOT FIXED. THE DEALERSHIP SAYS THAT THE OIL IS LEAKING FROM THE ENGINE. THE TRANSMISSION HAD TO HAVE A SEAL REPLACE A LINE, AND THE ENGINE IS STILL LEAKING. THE OWNER SAYS THAT HE CAN NOT DRIVE THE DRIVE BECAUSE IT WILL BLOW UP THE ENGINE. THE OWNER REFUSED TO DRIVE THE CAR WHEN HE FOUND ALL THESE PROBLEMS, SO HE DIDN'T BURN THE CAR UP. THERE HAVE BEEN TWO DIFFERENT DEALERSHIPS THAT HAVE WORKED ON THE CAR. THE OWNER SAID THAT THE DEALERS HAD CLAIMED TO FIX THE CAR, BUT DID NOT FIX IT. THE CAR ALSO HAS HAD A TIRE PROBLEM THAT THE OWNER HAD TO REPLACE. THE DEALERSHIP SAID THAT IT WAS WEAR AND TEAR. THE CAR HAS LESS THAN 800 MILES ON IT. *AK

I HAVE MANUAL TRANSMISSION. WHEN YOU PUT IT IN REVERSE IT WOULD NOT GO BACKWARD. I TOOK IT TO THE DEALER, WHEN I GOT THE CAR BACK, SECOND GEAR GRINDED VERY BADLY. I DID NOT HAVE THIS PROBLEM WHEN I INITIALLY TOOK THE CAR IN. THEY KEPT TELLING ME TO DRIVE THE CAR AND IT WOULD WORK, IT WAY OUT. IT DID NOT WORK ITS WAY OUT, AND I TOOK IT BACK IN FOR REPAIRS. THEY HAD THE CAR 9 DAYS. AFTER I PICKED THE CAR UP, A FEW DAYS LATER I REALIZED THE REVERSE LIGHTS WERE NOT WORKING, I TOOK IT BACK TO THE DEALER AND THEY SAID IT WAS A FUSE . A FEW WEEKS LATER I REALIZED IT WAS OUT AGAIN, THEY AGAIN SAID IT WAS A FUSE, AND THEY SAID IT WAS NOT WORKING BECAUSE OF MY AFTERMARKET RADIO. I DECIDED TO JUST DROP THE CAR OFF IN THE DEALERS AFTER HOUR DROP BOX TO MAKE THEM LOOK AT IT BECAUSE OF THE REVERSE LIGHTS NOT WORKING. IT TURNS OUT THE CIRCUIT BREAKER AND SWITCH WERE BROKEN AND HAD TO BE REPLACED. I JUST RECEIVED THE CAR BACK TODAY AND NOW THE "CHECK ENGINE" LIGHT IS ON. I NOTICED THIS BEFORE I EVEN GOT OUT OF THE DEALER'S LOT. THE CHECK ENGINE LIGHT WAS NOT ON WHEN I TURNED THE CAR IN. I TURNED THE CAR AROUND AND THE DEALER TOLD ME THEY WERE TO BUSY AND COULD NOT TAKE THE CAR BACK SO I DO NOT KNOW WHY THE CHECK ENGINE LIGHT IS ON. ALL OF THESE COMPLAINTS ARE IN REGARDS TO THE TRANSMISSION. I HAVE NO IDEA WHAT THE CHECK ENGINE LIGHT IS FROM BECAUSE THEY WILL NOT TAKE THE CAR IN UNTIL SUNDAY. *AK
WHEN CONSUMER APPLIED THE CLUTCH PEDAL IT CAUSED THE ENGINE TO RISE UP FROM 100 TO 3000 RPMS. VEHICLE WAS TAKEN TO THE DEALER, AND FLOOR MANAGER DETERMINED THERE WAS SOMETHING WRONG WITH CAR. HOWEVER, THE MANUFACTURER INDICATED NOTHING WAS WRONG WITH THE VEHICLE. *AK
I BOUGHT A 2004 FORD MUSTANG ON 9/15/03. THE REAR DIFFERENTIAL WAS FAULTY, CAUSING ME TO TAKE IT TO THE DEALERSHIP TO BE REPLACED ON 10/28/03. THE REAR END WHINES AND IS WOBBLY WHILE MAKING ANY TURNS, LEFT OR RIGHT.*AK
