The 1999LINCOLNNAVIGATOR carries 155 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 10 crashes, 12 fires, 12 injuries, and 2 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.

Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 1 investigation file overlapping the 1999 NAVIGATOR. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page, a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

WE HAD DRIVEN THE VEHICLE ABOUT ONE MILE FROM THE BEACH TO A RESTAURANT, WHERE WE PARKED AS USUAL AND ENTERED TO DINE. WE HAD BEEN IN THE RESTAURANT APPROXIMATELY 15 - 20 MINUTES WHEN THE WAITER ANNOUNCED THAT THERE WAS A "CAR ON FIRE" IN THE PARKING LOT. MY FAMILY AND I, ALONG WITH EVERYONE ELSE IN THE RESTAURANT, RUSHED OUTSIDE, WHERE I WAS HORRIFIED TO SEE MY LINCOLN NAVIGATOR SURROUNDED BY POLICE CARS AND ENGULFED IN FLAMES. I HAVE PHOTOS ON MY PHONE IF NECESSARY. THE FIRE HAD VERY OBVIOUSLY STARTED IN THE ENGINE COMPARTMENT AND PROBABLY ON THE DRIVER'S SIDE, AS THE FRONT TIRE ON THAT SIDE HAD MELTED AND WAS FLAT, BUT THE OTHER TIRES WERE ALL INTACT. I HAVE SINCE BEEN MADE AWARE OF A FAULTY SWITCH RELATED TO THE CRUISE CONTROL THAT CAN CAUSE THESE PROBLEMS. I AM ALMOST CERTAIN THAT WE TOOK OUR VEHICLE IN AND HAD THAT RECALL DEALT WITH YEARS AGO. I WILL SEARCH FOR PAPERWORK. I REMEMBER SOME REPAIR BEING DONE AT THE DEALER, BUT I CANNOT REMEMBER IF IT WAS A RECALL OR JUST SOM

WATER, VAPOR, CONDENSATION KEEPS GETTING ON TO THE COIL ON PLUG ASSEMBLY ON THE PASSENGER SIDE OF MY ENGINE CAUSING WATER BUILD UP, ELECTRICAL FAILURE, MISFIRES AND SPARK PLUG EXPLOSIONS IN TO MY ENGINE, CAUSING FRAGMENTS OF METAL AND PLASTIC TO FIRE IN TO MY ENGINE. THIS HAS HAPPENED TO ME SEVERAL TIMES NOW, BEEN REPAIRED, AND CONTINUES TO HAPPEN. DESPITE 6 SEPARATE TECHNICAL SERVICE BULLETINS, FORD / LINCOLN HAVE NOT RECALLED THIS PROBLEM WITH THE 1999 TO 2006 5.4L V8 ENGINE, LEADING TO THOUSANDS OF PEOPLE LIKE ME HAVING TO CONTINUALLY FIX THIS PROBLEM, WHICH IS CAUSED BY A DESIGN / SAFETY FLAW IN THE ENGINE / COMPONENT CONSTRUCTION. I WAS NEARLY KILLED TODAY ON THE FREEWAY BECAUSE THE TRUCK HESITATED AND MISFIRED WHILE I WAS GOING UP A LARGE HILL, STUCK BETWEEN TWO SEMI-TRUCKS AND I COULDN'T MOVE OUT OF THE WAY DUE TO FAILURE TO ACCELERATE. *TR
