WE WERE DRIVING DOWN THE HIGHWAY AT APPROXIMATELY 70MPH, WHEN I HEARD A LOUD POP AND CLANKING NOISE ON THE DRIVER'S SIDE FRONT ENGINE AREA. I WAS DRIVING WITH MY WHOLE FAMILY IN THE SUV. WE WERE ABLE TO STILL DRIVE IT TO A MECHANIC. THE MECHANIC DIAGNOSED IT AS A "BLOWN-OUT SPARK PLUG". HE SAID THE SPARK PLUG HAD COME OUT OF THE…

WE WERE DRIVING DOWN THE HIGHWAY AT APPROXIMATELY 70MPH, WHEN I HEARD A LOUD POP AND CLANKING NOISE ON THE DRIVER'S SIDE FRONT ENGINE AREA. I WAS DRIVING WITH MY WHOLE FAMILY IN THE SUV. WE WERE ABLE TO STILL DRIVE IT TO A MECHANIC. THE MECHANIC DIAGNOSED IT AS A "BLOWN-OUT SPARK PLUG". HE SAID THE SPARK PLUG HAD COME OUT OF THE ENGINE BLOCK. HE SAID IT IS A COMMON PROBLEM ON THAT ENGINE AND THERE WAS A SPARK PLUG KIT FOR IT. HE USED THE KIT, AND IT ONLY HELD FOR ABOUT 2 MONTHS. IT NOW HAS LOST POWER, SHAKES, AND POOR GAS MILEAGE. THE REPAIR KIT OBVIOUSLY IS NOT AMPLE FOR THIS PROBLEM. *TR

THIS IS THE FIFTH (5TH) TIME IN 6 YEARS I HAVE BROUGHT MY CAR IN FOR REPAIR OF THE AIR SUSPENSION (COMPRESSOR, RIDE HEIGHT) , ALL BUT ONE OF THOSE TIMES WAS TO THE FORD LINCOLN DEALERSHIP. IT IS CLEAR THAT FORD IS AWARE OF THE PROBLEM AS THERE ARE 10 SERVICE BULLETINS ON THE 2003 AIR SUSPENSION ALONE, AS WELL AS HUNDREDS OF COMPLAINTS ON THE INTERNET (SEE COMPLAINTS ON EDMUNDS, EVEN FORDS WEBSITE AND SEVERAL CAR FORUMS. THESE ARE OF THE LINCOLN NAVIGATOR ONLY, NOT ITS EQUIVALENT FORD EXPEDITION, WHICH ALSO HAS HOSTS OF COMPLAINTS.) MANY OF THE COMPLAINTS STATE, MUCH LIKE MY EXPERIENCE, THAT THE DEALER CANNOT EVEN FIGURE OUT THE PROBLEM. IT IS IMPOSSIBLE TO DESCRIBE TO YOU THE DANGER INVOLVED WHEN THE SUSPENSION FAILS, ESPECIALLY AT HIGHWAY SPEEDS. THE CAR BOUNCES VIOLENTLY AND BECOMES TOTALLY UNCONTROLLABLE. *TR

I BOUGHT MY USED 2003 LINCOLN NAVIGATOR IN 2008. A YEAR LATER, AIR SUSPENSION FAILURE HAPPENED SEVERAL TIMES. BOTH IN CITY AND ON HIGHWAY - VARIOUS SPEEDS - BUT THE SCARIEST AND MOST DANGEROUS WAS WHEN IT HAPPENED ON THE HIGHWAYS. CAUSED VEHICLE TO LOSE ALL SUSPENSION AND DROP EXTREMELY LOW. THE NAVI BOUNCED DANGEROUSLY AND VIOLENTLY EVEN AT VERY REDUCED SPEEDS. IT ALSO CAUSED THE NAVI TO SCRAPE THE GROUND ON A FEW OCCASIONS. HAD IT REPAIRED THREE TIMES @ $500+ AND WAS FINALLY TOLD THAT I NEEDED TO REPLACE ALL FOUR @ APPX $2000+!! I WAS ALSO TOLD THAT THIS IS A KNOWN PROBLEM WITH NAVI'S. IN ORDER TO SAVE MY TIME, MONEY AND SANITY, I OPTED FOR SPRING-SUSPENSIONS AT A THIRD OF THE COST AND HAVE NOT HAD ANY PROBLEMS WITH THOSE IN OVER 4 YEARS! I HIGHLY RECOMMEND THE SPRING-SUSPENSIONS AND STOP THE INSANITY. *TR
