2004 LINCOLN AVIATOR Engine And Engine Coolingengine Problems

2004 LINCOLN AVIATOR 74,000 MILES. WHILE ATTEMPTING TO MERGE ONTO INTERSTATE 95 S THE VEHICLE SHUDDERED AND LOST POWER UNABLE TO ACCELERATE. FINAL DETERMINATION BY A MECHANIC DETERMINED THE #8 CYLINDER WAS NOT HOLDING PRESSURE BECAUSE THE VALVE WAS NOT SEALING CORRECTLY. THE 4.6L V8 FORD ENGINE'S VALVE'S ARE POWDER COATED AND THIS CAUSED THE VALUE TO STICK AND OVERTIME WARPED THE VALVE'S COMPONENTS DUE TO EXCESSIVE HEAT. THIS IS AN ENGINE DESIGN DEFECT AND THE ENGINE AND WILL REQUIRE A COMPLETE VALVE JOB TO REPLACE THE HEAD, HEAD GASKET AND FAULTY VALVE STEM. FORD HAS ISSUED A TECHNICAL BULLETIN ON THE SUBJECT BUT WILL NOT PERFORM A VOLUNTARY RECALL. THIS IS A SERIOUS SAFETY ISSUE AND COULD CAUSE SERIOUS INJURY OR DEATH IF THE VEHICLE LOSSES POWER WHILE MERGING WITH OR EVADING ONCOMING TRAFFIC. *TR

I RECENTLY PURCHASED A 2004 LINCOLN AVIATOR. ABOUT A MONTH AFTER I PURCHASED THIS VEHICLE IT STARTED TO DEVELOP PROBLEMS. THE REAR BEARING SEAL FAILED AND OIL IS LEAKING OUT. THE GEAR SHIFTER ON THE CONSOLE IS STARTING TO STICK AND NOT GO INTO GEAR. I UNDERSTAND THE AVIATOR IS HAVING A LOT OF PROBLEMS IN THESE AREAS. THE VEHICLE ONLY HAD 79000 MILES ON IT WHEN I PURCHASED IT. FORD MUST HAVE USED INFERIOR MATERIALS TO MAKE THE AVIATOR. PLEASE LOOK INTO THIS AND IF SO FORCE FORD TO RECALL THE AVIATOR AND REPLACE THE INFERIOR PARTS WITH PARTS THAT ARE SAFE AND RELIABLE. *TR

I PURCHASED AN 04 LINCOLN AVIATOR IN DEC. 2006, IN AUG. 2007 I NOTICED IT WAS NOT RUNNING RIGHT. IT WAS STALLING WHEN ACCELERATING OR DECELERATING. IT WOULD SPUTTER LIKE IT WAS OUT OF FUEL. THE PROBLEM WORSENED FOR THE NEXT 6 WKS. NO MECHANIC COULD TELL ME WHAT WAS WRONG BECAUSE THE ENGINE LIGHT HAD NOT COME ON. IN OCT. 2007, I WAS DRIVING ON THE INTERSTATE WHEN MY CAR LOST ALL POWER FOR A SPLIT SECOND. I TOOK IT TO THE MECHANIC WHO COULD NOT TELL ME WHAT WAS WRONG STILL. THEN MY CHECK ENGINE LIGHT CAME ON AND I WAS TOLD IT WAS A COIL PACK. I HAD THAT REPLACED AND 2 DAYS LATER, THE PROBLEM STARTED AGAIN. I WENT TO MY MECHANIC WHO TOLD ME TO TAKE THE CAR TO FORD, BECAUSE A CAR WITH THAT FEW MILES SHOULD NOT BE HAVING ENGINE TROUBLE. I TOOK...

CHECK ENGINE LIGHT CAME ON 2 YEARS AGO OR SO. TOOK INTO SHOP. REPLACED COIL #8 AND SPARK PLUGS. SEVERAL MONTHS LATER, LIGHT COMES ON AGAIN, THIS TIME #7. 2 DAYS LATER, LIGHT COMES ON AGAIN, MUST HAVE BEEN A DEFECTIVE PART, REPLACED THE REPLACED #7. ANOTHER 2 DAYS LATER, LIGHT BACK ON. I'M TOLD IT'S A CYLINDER HEAD PROBLEM AND THEY WON'T KNOW WHAT EXACTLY THE PROBLEM IS UNTIL THEY TAKE THE CYLINDER HEADS OFF. OR I CAN GET A NEW ENGINE.... LINCOLN WANTS NO RESPONSIBILITY FOR SUCH A CATASTROPHIC AND KNOWN PROBLEM. SINCE MY MILEAGE IS OVER THEIR WARRANTY (ALTHOUGH AT THE ONSET IT WASN'T). GEE, I WONDER WHY NO ONE WANTS TO BUY AN AMERICAN MADE CAR! *TR

AT 13,650 MILES THE ENGINE DESTROYED ITSELF DUE TO A DEFECTIVE CRANKSHAFT. I WAS DRIVING HOME AT NIGHT IN THE RAIN WHEN THE ENGINE LIGHT CAME ON AND A LOUD BANGING SOUND WAS COMING FROM THE ENGINE COMPARTMENT. I IMMEDIATELY PULLED OFF THE HIGHWAY & CALLED ROADSIDE ASSISTANCE. I WAITED FOR 3 HOURS FOR A TOW TRUCK AND EVENTUALLY HAD TO CALL CT STATE POLICE WHO SUMMONED A WRECKER. THE LOWER HALF OF THE ENGINE WAS COMPLETELY DESTROYED. MANUFACTURER REPLACED THE ENGINE WITH A NEW ENGINE ASSEMBLY AND ENGINEERS REQUESTED THE OLD ENGINE BE SENT TO THEM FOR INSPECTION AS THEY HAD NEVER SEEN THIS DEFECT BEFORE. I WAS WITHOUT MY VEHICLE FOR 15 DAYS. THE FIRST NIGHT I PICKED IT UP THE ENGINE LIGHT CAME ON AFTER LESS THAN 20 MILES ON MY WAY HOME, AGAIN AT NIGHT. IT WAS NOT A DUMMY LIGHT. ANOTHER DEFECTIVE PART HAD TO...
