For the past 6-8 months my vehicle has sporadically stalled/stopped for no apparent reason. When it stops like this it can occur on the highway or surface streets without notice. I have taken it to the Lincoln dealer two times with the last time being told it was a transmission problem, which I was skeptical, because of no previous problems. I have requested assistance from Ford motor who essentially dismissed without any liability due to the car being out of warranty. I am requesting your assistance before there is any injury, accident or fatality. I have the E-mail correspondence with Ford.

The number three spark plug on the passenger side of my 2004 Lincoln Navigator blew out. The car has 72000 mile on it and is excellent condition. This is defect, there should be more threads holding the spark plug in pace, this car uses aluminum cylinder heads, the manufactures design did not put enough threads in place for aluminum to hold the plug over the usable life of the car and engine.

Noticed the air compressor ran all of the time for the air ride system. The car was still in warranty took it to Ford and they said they had fixed the problem. 800 miles out of warranty the ride side air shock went bad and burned out the compressor. Looked up old paper work and come to find out that they has put on a noise reduction kit on the compressor. So we could no longer hear it run. Contact the dealership as well as customer service at Lincoln. They told us sorry about your luck it is out of warranty. Took it to a different dealer and they said that the bags on the air ride system were dry rotted (the truck has 50,800 miles. He said this a common problem with Ford and Lincoln. They replace at least 8 sets a week. I had the right side fixed, new compressor. Now 7 months later the left side as done the same thing (55,000 miles).

: the contact stated while driving 70mph on the interstate, the speed decreased to 50mph followed by the illumination of the check engine light. The vehicle was seen by a dealer. The mechanic determined the vacuum module on the engine failed. The engine vacuum module was replaced by the dealer.
