DUCK THIS THIS IS SUPPOSE TO BE A LUXURY SUV FOR MY AND MY 4 CHILDREN. I SHOULDN'T HAVE THESE MANY PROBLEMS CONSIDERING THE PRICE I PAID HELLO..... MY DAD IS A MECHANIC FOR TOYOTA AND NOW I UNDERSTAND WHY HE ONLY BUYS TOYOTAS TO.
FOR THE PAST 6-8 MONTHS MY VEHICLE HAS SPORADICALLY STALLED/STOPPED FOR NO APPARENT REASON. WHEN IT STOPS LIKE THIS IT CAN OCCUR ON THE HIGHWAY OR SURFACE STREETS WITHOUT NOTICE. I HAVE TAKEN IT TO THE LINCOLN DEALER TWO TIMES WITH THE LAST TIME BEING TOLD IT WAS A TRANSMISSION PROBLEM, WHICH I WAS SKEPTICAL, BECAUSE OF NO PREVIOUS PROBLEMS. I HAVE REQUESTED ASSISTANCE FROM FORD MOTOR WHO ESSENTIALLY DISMISSED WITHOUT ANY LIABILITY DUE TO THE CAR BEING OUT OF WARRANTY. I AM REQUESTING YOUR ASSISTANCE BEFORE THERE IS ANY INJURY, ACCIDENT OR FATALITY. I HAVE THE E-MAIL CORRESPONDENCE WITH FORD. *TR
TL* THE CONTACT OWNS A 2004 LINCOLN NAVIGATOR. THE CONTACT WAS DRIVING 65 MPH WHEN THE ENGINE STALLED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE DEALER. THE DEALER CONFIRMED THERE WAS AN ENGINE MISFIRE. THE MANUFACTURER WAS CONTACTED AND THE VEHICLE WAS REPAIRED. THE VIN WAS UNAVAILABLE. THE FAILURE MILEAGE WAS 54,000 AND THE CURRENT MILEAGE WAS 75,000.
THE NUMBER THREE SPARK PLUG ON THE PASSENGER SIDE OF MY 2004 LINCOLN NAVIGATOR BLEW OUT. THE CAR HAS 72000 MILE ON IT AND IS EXCELLENT CONDITION. THIS IS DEFECT, THERE SHOULD BE MORE THREADS HOLDING THE SPARK PLUG IN PACE, THIS CAR USES ALUMINUM CYLINDER HEADS, THE MANUFACTURES DESIGN DID NOT PUT ENOUGH THREADS IN PLACE FOR ALUMINUM TO HOLD THE PLUG OVER THE USABLE LIFE OF THE CAR AND ENGINE. *TR
SPARK PLUGS EJECTED FROM CYLINDER HEAD. *TR
NOTICED THE AIR COMPRESSOR RAN ALL OF THE TIME FOR THE AIR RIDE SYSTEM. THE CAR WAS STILL IN WARRANTY TOOK IT TO FORD AND THEY SAID THEY HAD FIXED THE PROBLEM. 800 MILES OUT OF WARRANTY THE RIDE SIDE AIR SHOCK WENT BAD AND BURNED OUT THE COMPRESSOR. LOOKED UP OLD PAPER WORK AND COME TO FIND OUT THAT THEY HAS PUT ON A NOISE REDUCTION KIT ON THE COMPRESSOR. SO WE COULD NO LONGER HEAR IT RUN. CONTACT THE DEALERSHIP AS WELL AS CUSTOMER SERVICE AT LINCOLN. THEY TOLD US SORRY ABOUT YOUR LUCK IT IS OUT OF WARRANTY. TOOK IT TO A DIFFERENT DEALER AND THEY SAID THAT THE BAGS ON THE AIR RIDE SYSTEM WERE DRY ROTTED (THE TRUCK HAS 50,800 MILES. HE SAID THIS A COMMON PROBLEM WITH FORD AND LINCOLN. THEY REPLACE AT LEAST 8 SETS A WEEK. I HAD THE RIGHT SIDE FIXED, NEW COMPRESSOR. NOW 7 MONTHS LATER THE LEFT SIDE AS DONE THE SAME THING (55,000 MILES). *TR
FIRST WEEK IN DECEMBER TOOK 2004 NAVIGATOR WITH 29,000 MILES TO DEALERSHIP AFTER HEARING A VERY CLUNKING SOUND. I WAS TOLD IT NEEDED A CATALYTIC CONVERTER. DEALERSHIP STATED THAT IT WOULD TAKE 2 WEEKS FOR PART. I CALLED LINCOLN TO STATE MY COMPLAIN AS TO WHY IT WAS GOING TAKE SO LONG AND WAS TOLD THE WAREHOUSE THAT STORED THEM BURNT DOWN. TOO MAKE A VERY TRYING STORY SHORT IT WILL BE 2 MONTHS UNTIL I GET MY NAVIGATOR REPAIRED. THE DEALERSHIP TOLD ME THAT THEY WERE TOLD BY LINCOLN THAT THE PART HAS TO BE MADE AND THEN TESTED BEFORE THEY SHIP IT TO THE DEALERSHIP. I HAVE NEVER HEARD OF SUCH A THING. I CAN NOW UNDERSTAND WHY PEOPLE ARE BUYING THE IMPORTS AND WHY AMERICAN CAR MAKERS ARE HURTING. I WILL NOT BUY ANOTHER LINCOLN AGAIN. *JB
DT*: THE CONTACT STATED THE VEHICLE HAD BEEN AT THE DEALER FOR TWO MONTHS FOR A CATALYTIC CONVERTER REPLACEMENT, HOWEVER THE PARTS WERE NOT AVAILABLE. UPDATED 12/18/06. *JB
IN NOV 05 THE CAR STARTED TO SHUT OFF MOMENTARILY AS YOU STARTED TO DRIVE, IT WOULD DO IT ONLY WHEN YOU WOULD TAKE OFF FROM A STOP AND NEVER AT FREEWAY SPEEDS. THIS WOULD OCCUR 50% OF THE TIME. THE DEALER HAD IT ON 11-7 AND REPLACED THE CAM POSITION SENSOR. WHEN I PICKED IT UP ON 11-8 IT WAS WORSE THAN BEFORE. I RETURNED IT ON 11-9 THEY RETURNED IT ON 11-19 AFTER REPLACING ONE OF THE COILS. THIS HELPED BUT DIDN'T SOLVE THE PROBLEM, STILL HAD THE HESITATION LEAVING A STOP BUT ONLY HAPPENED 2-3 TIMES IN THE 1ST WEEK. IN THE 2ND WEEK AS I SLOWED DOWN FOR A STOP IT SHUT COMPLETELY OFF, WHEN I PUT IT IN NEUTRAL , TURNED THE IGNITION OFF AND BACK ON IT STARTED. IT CONTINUED TO HESITATE AT TIME WHEN YOU WERE DRIVING IN CITY TRAFFIC BUT WOULD NOT SHUT COMPLETELY OFF. THIS PAST WEEK THE HESITATIONS BECAME MORE FREQUENT AND ON TUGS 5-16 IT SHUT DOWN TOTALLY IN HEAVY TRAFFIC AS I TURNED A CORNER. I DELIVERED THE CAR BACK TO THE DEALER IN THE AFTERNOON, HE CALL AND SAID NOTHING COULD BE FOUND AND COULD ONE OF THE TECHS DRIVE IT HOME FOR A TEST DRIVE, I AGREED. HE CALLED AND REPORTED THE CAR RUNS PERFECT AND THEY CAN'T DO ANYTHING IF THEY DON'T KNOW WHAT THE PROBLEM IS. THE CAR NOW SHUTS OFF MOMENTARILY AT FREEWAY SPEEDS AND IS VERY VIOLENT. THE CAR ONCE ACTED LIKE IT WAS RUNNING ON 4 CYLINDERS AND SLOWED DOWN TO 30 MPH, AFTER PULLING OVER ON THE FREEWAY SHUTTING THE KEY OFF IT WORK K AGAIN. DEALER STILL CAN'T DETECT WHAT IS WRONG IN SEPTEMBER 2006. *NM
DT*: THE CONTACT STATED WHILE DRIVING 70MPH ON THE INTERSTATE, THE SPEED DECREASED TO 50MPH FOLLOWED BY THE ILLUMINATION OF THE CHECK ENGINE LIGHT. THE VEHICLE WAS SEEN BY A DEALER. THE MECHANIC DETERMINED THE VACUUM MODULE ON THE ENGINE FAILED. THE ENGINE VACUUM MODULE WAS REPLACED BY THE DEALER.
