I OWN A 2003 LINCOLN NAVIGATOR WITH THE 5.4 LITER ENGINE AND I HAVE AN OIL LEAK COMING FROM BOTH BACK CORNERS ON EACH OF THE CYLINDER HEAD GASKETS. MY MECHANIC SHOP DID RESEARCH AND FOUND THAT DURING THIS YEAR OF 2003 THE GASKETS COULD OF BEEN DAMAGED DURING INSTALLATION AT THE MANUFACTURING PLANT. I FEEL LIKE THIS ISSUE NEEDS TO BE ADDRESSED AND FOR FORD MOTOR COMPANY TO ISSUE A RECALL ON THIS MATTER. *TR

MY 2003 LINCOLN NAVIGATOR HAS SHUT DOWN COMPLETELY THREE TIMES IN THE LAST 6 WEEKS. TWO OF THE OCCASIONS HAPPENED ON THE INTERSTATE WHILE DRIVING ABOUT 55 MPH, THE THIRD INSTANCE HAPPENED IN MY SUBDIVISION DRIVING LESS THAN 30 MPH. AFTER PULLING THE TRUCK OVER TO THE SIDE FOR SAFETY THE TRUCK WILL NOT START IMMEDIATELY BUT WILL START AFTER RESTING ABOUT 7 MINUTES. WHEN THE TRUCK SHUTS DOWN SEVERAL LIGHTS ON THE DASHBOARD LIGHT UP. I EXPLAINED THE ISSUE AS WELL AS I COULD TO MY LOCAL FORD / LINCOLN DEALERSHIP IN MADISON, TN BUT THEY COULD NOT FIND ANY ISSUES WITH IT SAYING THAT NO CODES WERE SHOWING. I ALSO TOOK THE TRUCK TO A GOODYEAR SERVICE REPAIR IN BRENTWOOD, TN BUT THEY ALSO COULD NOT DIAGNOSE THE PROBLEM. AFTER SEARCHING FOR THIS TYPE OF ISSUE ON THE INTERNET I FOUND NUMEROUS CUSTOMERS THAT HAVE HAD A SIMILAR EXPERIENCE, SOME SAYING THAT THE ISSUE IS RELATED TO THE "FAIL SAFE" SECURITY OPTION KICKING IN WHILE A PERSON IS DRIVING. THE ISSUE OF HAVING MY TRUCK SHUT DOWN COMPLETELY ON THE INTERSTATE IS DANGEROUS AND I WOULD APPRECIATE HELP ON GETTING THE ISSUE RESOLVED AS SOON AS POSSIBLE.

I BOUGHT A USED 2003 LINCOLN NAVIGATOR WITH A BIG 5.4-LITER V-8 ENGINE FROM WITTMEIER FORD IN CHICO, CA. IN 2004. THE NAVIGATOR LOOKED LIKE A GREAT DEAL. THE PRICE WAS $43,000. THE NAVIGATOR HAD ONLY 23,000 MILES ON THE ODOMETER. BUT THE GREAT DEAL BLEW UP IN MY FACE WHEN THE USED LINCOLN NAVIGATOR SPIT A SPARK PLUG AT 81,000 MILES. THE CHECK ENGINE LIGHT CAME ON AS THE TRUCK BEGAN TO LOSE POWER. AS WE DROVE THE CAR IT CONTINUED TO BACK FIRE. THE IGNITION PACK FOR THAT PLUG WAS SHREDDED. I CALLED WITTMEIER SERVICE AND THEY SAID THEY KNEW NOTHING OF THE PROBLEM. THE THREADS IN THE NUMBER 3 SPARK PLUG HOLE IN THE NAVIGATOR WERE STRIPPED. WE NEEDED TO RE-THREAD THE NUMBER 3 SPARK PLUG HOLE AND REPLACE THE IGNITION PACK. I READ ON THE INTERNET WHERE THIS IS A COMMON PROBLEM AND IT WILL LIKELY HAPPEN AGAIN. I BELIEVE FORD SHOULD TAKE CARE OF THIS PROBLEM. *TR

MY 2003 LINCOLN NAVIGATOR ULTIMATE @ 84,000 MILES BLEW 2 SPARK PLUGS THROUGH THE ALUMINUM HEAD OF THE 5.4 LITER TRITON ENGINE. IT IS MY UNDERSTANDING THAT THIS ALUMINUM HEAD HAS BEEN REDESIGNED BY FORD AND THAT THERE IS ALSO AN AFTER-MARKET FIX TO THIS INCREASING PROBLEM THAT RE-THREADS THE SPARK PLUGS, BUT THAT SAID FIX ALSO GETS FORCED THROUGH SAID INADEQUATELY ENGINEERED ALUMINUM HEAD. FOR REFUSES TO PAY FOR THE REPLACEMENT OF SAID HEAD AND SAID REPAIR IS ESTIMATED IN THE THOUSANDS OF DOLLARS. I REPLACED THE MELTED COIL AND BARELY WAS ABLE TO THREAD NEW PLUGS INTO PLACE, BUT I AM CONCERNED ABOUT BEING STRANDED SOMEWHERE IN MY CAR. I THINK THAT FORD SHOULD HAVE TO RECALL ALL OF THESE ENGINES AND REPLACE THE OLD HEADS WITH NEW, BETTER ENGINEERED HEADS. *JB
