Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Engine was missing when trying to accelerate or pass vehicles. Dangerous situation when trying to pass on highways and interstates. Took 2006 Lincoln Navigator in for new spark plugs. Dealer said all 8 plugs broke off and one damaged the head and now need new head due to broken spark plug. Cost will exceed $3,000. Spoke with 6 local mechanics and all agreed this is a big problem. Why should I pay for Ford's faulty design?

2006 Lincoln Navigator, 60,000 miles on car. Car shut down after giving an engine failed safety mode error on dash while on four lane busy highway traveling 40-45 mph. Coasted to side of road (no berm available)... waited 5 minutes. Restarted car and limped into gary yeoman Ford dealer. I was told the throttle control body & motor asy #3L3Z*9E926 was bad and was not covered under the extended warranty I purchased on the car in 2009. Repair bill was $900 out of pocket. Checked online and this is a known issue for Ford Expedition & Lincoln Navigator engines and yet Ford does nothing to fix. Does someone have to die to get Ford to repair these defective parts? nothing more dangerous than a car that shuts down in heavy traffic traveling at high speeds.

Engine shut down at 45 miles an hour. Fail-safe light illuminated followed by a loss of power steering. Coasted car to the side of road and turned key to off position. The engine immediately restarted with no other problems. This car has 79,000 miles on it and I have owned it since new. This has not happened since the car was new. The dealer took the problem seriously, but can never find a problem. It seems to be a computer problem with the fail-safe mode.

The contact owns a 2006 Lincoln Navigator. The contact was driving approximately between 40-45 mph when the safe engine mode warning light illuminated and then the vehicle immediately stalled. The engine restarted and resumed operation. The vehicle was taken to the dealer five times regarding the similar failure. The technician reprogrammed the computerized system software and the fuel pump was replaced at a different time. The failure persisted after the repairs. Also, most recent the temperature warning indicator illuminated during the engine malfunction. The vehicle was currently at the dealer for diagnostic testing and a trouble code was not detected. The dealer was unable to locate the problem. The manufacturer had been notified in which there were no resolutions. The failure mileage was unknown.

2006 Lincoln Navigator. Fail safe mode comes on while driving and shuts vehicle down. This has happened twice and also exact same incident to friend in different state with same 2006 Navigator. Decided to report after I called Lincoln and they had record of my call in December 2009 and January 2010 but no record of the work performed to correct the problem or the dangerous incident. It happened again September 23, 2010 after it was supposed to have been fixed by changing a sensor. This is extremely dangerous!! car shuts down and my wife was almost rear ended at highway speeds. On google search of "Lincoln Navigator fail safe mode problems" there are 1380 results. Goes to over 2500 when 2006 is removed. During first "fix" Ford dealership replaced a sensor but the details are not documented in my file on the Ford/Lincoln computer system. This could be how Ford/Lincoln is avoiding a major recall for a extraordinarily dangerous problem.
