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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

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.

Ltr from senator hutchison on behalf of constituent, re problems with her 2005 Lincoln Navigator. The consumer stated there was a noise coming from the engine. The front end vibrated constantly. The consumer was informed the track bar and cad mount bushings needed to be replaced to correct the vibrating. The sunroof leaked, the cd changer scratched the cd's, the drivers seat was repaired 3 times, the tire pressure sensor didn't work, the remote start did not work, the transmission was slipping, the rear windows were grinding, the drivers side door would not open, the mirror would not adjust and the wipers were replaced. The consumer stated after two years of being told there was nothing wrong with the vehicle, it finally broke down and the dealer had to perform major engine work. After the engine work was completed the consumer stated the engine continued to make noise and there was also hesitation problems. Updated 03/01/10.

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).
