Open the full vehicle complaint log (all categories)AS I WAS MERGING ON FREEWAY, I EXPERIENCED SUDDEN LOSS OF POWER AND IT COULD HAVE RESULTED IN FATALITIES SINCE IT WAS AT RUSH HOUR. AS I PULLED OVER, THE ENGINE WAS BUCKING BUT REGAINED POWER WITH SPORADIC BOUTS OF LOSS DURING MY DRIVE HOME. THERE WAS A MISFIRE ON CYLINDER ONE AND I REPLACED AND TESTED ALL RELATED COMPONENTS AND THEN FOUND OUT IT WAS THE CAM PHASER ISSUE THAT PLAGUES THE TRITON ENGINE. FROM READING OTHER COMMENTS FROM BOTH CONSUMER AND REPAIR SHOP OWNERS, IT IS SIMPLY A DEFECTIVE PRODUCT FROM WHO ELSE, THE FORD CORP. OF COURSE THEY BLAME THE OWNER FOR LACK OF MAINTENANCE.
2005 NAVIGATOR HAS ONLY 60,000 MILES, SPARK PLUGS DEFECTED, DEALER WANTS $1,500 TO $2,500 TO REPLACE THEM, WHICH IS DEFECT FROM MANUFACTURE. THESE SPARK PLUGS SHOULD BE REPLACED DUE TO DEFECTS FROM MANUFACTURE, AND THE RECALL ONLY WANTS TO PAY $1,040 FOR THE REPLACEMENT OF THE SPARK PLUGS, WHY SHOULD I PAY UP FRONT IF THEY ARE MANUFACTURE FAULT AND MY NAVIGATOR ONLY HAS 60,00 MILES NOW AND I PURCHASED IT NEW FROM THE DEALER IN 2005.
AIR BAGS ARE VERY LOUD AND THEY RUN OFTEN AIR CONDITIONING IN REAR MAKES A POPPING NOISE AIR CONDITIONING IN BLOWS THROUGH FLOOR VENTS WHEN I ACCELERATE I HAVEN'T BEEN ABLE TO FIX IT BECAUSE IT IS TOO EXPENSIVE. *TR
TL*THE CONTACT OWNS 2005 LINCOLN NAVIGATOR. THE CONTACT STATED THAT THEY HAD TO REPLACE THE ENGINE SINCE THE HEAD GASKET WAS DEFECTIVE AND THERE WAS A PISTON THAT CAUSED METAL SHAVINGS TO ENTER THE ENGINE. THE VEHICLE WAS DIAGNOSED BY THE DEALER SEVERAL TIMES SINCE A KNOCKING SOUND WAS IN THE ENGINE. THE DEALER WAS UNABLE TO FIND THE SOURCE OF THE KNOCKING SOUNDS IN THE ENGINE. SINCE THE VEHICLE WAS 5000 MILES OVER THE WARRANTY THE ENGINE FAILED. THE DEALER INSPECTED THE ENGINE AND STATED THAT IN NEEDED TO BE REPLACED. THE FAILURE AND CURRENT MILEAGES WERE 55000. UPDATED 11/05/10. *LJ
2005 LINCOLN NAVIGATOR HAS HAD LOSS OF POWER ON MULTIPLE OCCASIONS. I HAVE HAD THE VEHICLE SINCE NEW AND I HAVE TAKEN IT TO THE FORD DEALERS IN THE AREA 3 TIMES TO HAVE THE PROBLEM FIXED. DEALER HAS BEEN ABLE TO DUPLICATE THE PROBLEM BUT DOES NOT HAVE A SOLUTION TO FIX IT. VEHICLE HESITATES AND DOES NOT ACCELERATE CREATING A SERIOUS HAZARD WHEN ACCELERATION IS NEEDED. FORD HAS NO SOLUTION TO REPAIR THE PROBLEM AND I WAS TOLD TO CONTINUE DRIVING THE VEHICLE AND KEEP A LOG OF WHEN THE PROBLEM EXISTS (IE; WEATHER, TIME DATE ECT). *NM
MY CAR CONTINUES TO SHUT OFF WHILE DRIVING, HAVE HAD IT SERVICED ALREADY 3 TIMES AND THE PROBLEM PERSISTS. *JB
