REQUESTNG FORD BE MADE TO ISSUE A RECALL FOR EXHAUST MANIFOLD HOLES AND CRACKING ISSUES. THIS ISSUE IS KNOWN AND THE ARE MULTIPLE FORUMS ONLINE WHERE PEOPLE ARE TALKING ABOUT HAVING THIS ISSUE. WHEN THE MANIFOLD LEAKS, THE RISK IS THERE THAT EXHAUST FUMES CAN GET INTO THE DRIVING COMPARTMENT AND ASPHYXIATE THE PEOPLE IN THE CAR. IT IS AN EXPENSIVE REPAIR FOR AN ISSUE FOR SHOULD HAVE RESOLVED LONG AGO.
AFTER A RAINSTORM AND WHILE DRIVING, MY WINDSHIELD WIPERS STOPPED WORKING, MY RADIO/CD PLAYER STARTED TURNING OFF AND ON, MY PANEL LIGHT DIMMED, AND I HEARD A CLICKING NOISE UNDER MY DRIVER SIDE DASH BOARD. THERE WAS ALSO A CLICKING NOISE COMING FROM THE ENGINE. WHILE STATIONARY AND KEY OUT OF THE IGNITION, I NOTICED WATER ON THE DRIVER SIDE FLOOR, AND WHEN I LOOKED UNDER I COULD SEE DROPS OF WATER SLIDING OFF I BELIEVE MY EMERGENCY BAKE AND BRAKE PEDAL, AND AN ONGOING CLICKING SOUND UNDER THE STEERING WHEEL. I LEFT MY TRUCK IN DRIVEWAY OVERNIGHT, AND THE NEXT MORNING MY BATTERY WAS DEAD. I HAD AAA TOW COME AND REPLACE BATTERY THAT AFTERNOON. THE NEXT MORNING THE BATTERY WAS DEAD AGAIN. AAA CAME AND CHECKED THE STARTER AND ALTERNATOR, ALL WERE FINE. AS THEY RECHARGED BATTERY THERE WAS A WEIRD NOISE HEARD IN THE ENGINE AREA. I DROVE IT TO A MECHANIC WITH FORD TRUCK EXPERIENCE. HE STATED THE GEM AND FUSE BOX WERE WET AND ATTRIBUTED IT TO WATER LEAKAGE COMING FROM THE WINDSHIELD WEATHER STRIPPING TRIM WHICH WAS COMMON IN FORDS VEHICLES. HE RECOMMENDED REPLACING GEM, FUSE BOX, AND WINDSHIELD TRIM. THIS WATER/ELECTRICAL PROBLEM HAPPENS EVERY YEAR AFTER A RAINSTORM. I NEVER THOUGHT A VEHICLE IN GOOD CONDITION COULD HAVE OUTSIDE WATER LEAKS GETTING INSIDE AND ONTO THE FUSE BOX AND GEM MODULE. THE MECHANIC TOLD ME IT CAN BECOME VERY DANGEROUS FOR THE GEM AND FUSE BOX TO FAIL BECAUSE IT CONTROLS EVERYTHING IN THE TRUCK. THE GEM AND FUSE BOX SHOULD BE PROTECTED FROM OUTSIDE ELEMENTS. WHEN WATER IS INTRODUCED TO THESE MODULES, IT MAKES THE WHOLE SYSTEM GO WACKY AND CAN CAUSE SERIOUS AND POSSIBLY DANGEROUS SITUATIONS. FORD NEEDS TO ACKNOWLEDGE THAT THIS IS A MANUFACTURE DEFECT AND FIX AND/OR REIMBURSE US CONSUMERS ON THE COST OF FIXING IT

THE LOCAL DEALER AND MANUFACTURER WERE NOT CONTACTED. THE FAILURE MILEAGE WAS APPROXIMATELY 247,000.
TRANS WENT OUT A MONTH AFTER INTAKE CRACK HAD TO BE REPLACE ALMOST $1,650 TOGETHER ALSO BALL JOINTS AND TIEROD ENDS NO GOOD SHOCK NO GOOD BRAKE ARE FALLING AND REAR END IS GRINDING THIS TRUCK SHOULD HAVE NEVER BEEN SOLD HELP AND THERE'S "MORE".
THE SPARK PLUG EJECTED FROM MY ENGINE AND CYLINDER HEAD. AND APPARENTLY THIS IS A COMMON ISSUE WITH FORD TRUCK ENGINES. SEEMS TO ME IT SHOULD BE A DEFECT OR A RECALL. THAT SHOULD NOT HAPPEN IT COULD BE DANGEROUS. I THOUGHT MY VEHICLES ENGINE HAD EXPLODED. AND THE COST OF THIS COULD BE OUTRAGEOUS.
SPARK PLUG 2ND CLOSEST TO THE PASSENGER BLEW OUT.
WAS DRIVING ALONG AT 35 MPH GOING STRAIGHT ON A CITY STREET. A SPARK PLUG WAS EJECTED FROM THE ENGINE HEAD. THIS COULD CREATE A FIRE HAZARD.
VEHICLE CAUGHT ON FIRE WHILE PARKED IN DRIVEWAY. HAD NOT BEEN RUN IN OVER A WEEK. COMPLETELY BURNED UP AND CAUSED DAMAGED HOME. VEHICLE BURNED HAD SEVERAL EXPLOSIONS AND BURNED AT A HIGH TEMP UNTIL IT WAS EXTINGUISHED BY FIRE FIGHTERS.
DRIVING UP A HILL AT HIGHWAY SPEED I HEARD A LOUD BANG AND A CLUNK AND THE TRUCK STARTED SHAKING. I WAS QUITE STARTLED. I PULLED OVER IMMEDIATELY, SHUT IT OFF, AND FOUND THE SPARK PLUG HAD EJECTED FROM CYLINDER NUMBER 6. NOT BEING FAR FROM HOME, I ATTEMPTED TO DRIVE IT THE REST OF THE WAY ON LESS BUSY ROADS, BUT I HAD TO PULL OVER AGAIN WHEN I STARTED SMELLING A STRONG GASOLINE SMELL. I WAS ABLE TO DISCONNECT THE FUEL INJECTOR AND DRIVE IT THE REST OF THE WAY HOME, BUT I FEEL THERE WAS A DANGER OF AN ACCIDENT WHEN THE INCIDENT HAPPENED DUE TO THE SUDDEN LOSS OF POWER IN TRAFFIC ON A HILL, AND THEN A DANGER OF A FIRE WHEN I HAD TRIED TO CONTINUE DRIVING IT WITH THE FUEL INJECTOR ACTIVE.
SECOND TIME SAME SPARK PLUG HOUSING HAS FAILED TO HOLD SPARK PLUG AND EJECTED IT FROM ENGINE ALONG WITH RAW FUEL ALMOST IGNITING ENGINE COMPARTMENT.
WHILE DRIVING MY TRUCK WITH MY WIFE & SON, WE HEARD A LOUD POP, LIKE A GUN SHOT, THEN MY TRUCK STARTED TO RUN REAL ROUGH, I FOUND A COIL, & A SPARK PLUG HAD BEEN BLOWN OUT OF THE ENGINE, BECAUSE OF THE FUEL BUILD UP & THE SPARK FROM THE TRUCK STILL RUNNING WE ARE LUCKY THAT THE TRUCK DID NOT CATCH FIRE.
DRIVING DOWN HIGHWAY AND EXITING ONTO MY EXIT, THE TRUCK STARTED TO RUN ROUGH AND EVENTUALLY SHUT OFF. I HAD TO WAIT ABOUT 1HOUR FOR THE TRUCK TO COOL OFF BEFORE IT WOULD START AGAIN. WHILE WAITING FOR THE TRUCK TO COOL OFF, I CHANGED THE FUEL FILTER. TODAY, 6/3/15, I CAN START THE TRUCK UP AND LET IT RUN FOR ABOUT A HALF AN HOUR AND SHUT IT OFF AND IT WILL NOT START BACK. I WAIT ANOTHER HALF AN HOUR AND IT WILL START RIGHT UP. I CAN'T EFFORT TO TAKE IT TO THE SHOP AND PAY $50 TO $100 FOR THEM NOT TO BE ABLE TO TELL ME WHAT IS WRONG OR HOW TO FIX IT.
AS WE STARTED THE TRUCK, WE HEARD A LOUD POP AND THEN THE ENGINE WAS RUNNING ROUGH. I COULD SMELL GAS BURNING NOT IN A GOOD WAY, SO WE TURNED OFF THE ENGINE AND POPPED THE HOOD. THERE WAS GASOLINE RUNNING UNDER THE TRUCK, AND GASOLINE COMING FROM THE EXHAUST. A PASSERBY INFORMED US THAT THE F-150 WITH TRITON ENGINE IS NOTORIOUS FOR BLOWING SPARK PLUGS AND PROCEEDED TO POINT OUT WHICH SPARK PLUG HAD BLOWN. I RESEARCHED THIS ISSUE WHEN I ARRIVED HOME AFTER OUR TRUCK WAS TOWED TO A MECHANIC, AND DISCOVERED THAT JUST ABOUT EVERY F-150 OWNER GOES THROUGH THIS. WHY IS THIS NOT A DEFECT THAT FORD IS BEING REQUIRED TO FIX? DO PEOPLE HAVE TO DIE BEFORE A DEFECTIVE PART IS TAKEN CARE OF? *TR
