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.

2004 Lincoln Navigator Owner Comments

In Nov 05 the car started to shut off momentarily as you started to drive, it would do it only when you would take off from a stop and never at freeway speeds. This would occur 50% of the time. The dealer had it on 11-7 and replaced the cam position sensor. When I picked it up on 11-8 it was worse than before. I returned it on 11-9 they returned it on 11-19 after replacing one of the coils. This helped but didn't solve the problem, still had the hesitation leaving a stop but only happened 2-3 times in the 1st week. In the 2nd week as I slowed down for a stop it shut completely off, when I put it in neutral, turned the ignition off and back on it started. It continued to hesitate at time when you were driving in city traffic but would not shut completely off. This past week the hesitations became more frequent and on tugs 5-16 it shut down totally in heavy traffic as I turned a corner. I delivered the car back to the dealer in the afternoon, he call and said nothing could be found and could one of the techs drive it home for a test drive, I agreed. He called and reported the car runs perfect and they can't do anything if they don't know what the problem is. The car now shuts off momentarily at freeway speeds and is very violent. The car once acted like it was running on 4 cylinders and slowed down to 30 mph, after pulling over on the freeway shutting the key off it work K again. Dealer still can't detect what is wrong in September 2006.
