Problems with 2004 Lincoln Navigator EQUIPMENT

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). *tr

Problem with air suspension on vehicle. placed in shop over 7 or more times problem still not resolved. dealership has replaced parts but still same problem. *tr

Unable to operate satellite radio and rear entertainment dvd simultaneously. this is a design flaw of the radio which has only one aux input for both systems. this means that the occupants cannot listen to satellite radio on long trips while kids watch a dvd. dealer did not infom buyer of this problem and ford has no solution.*ak

The running board intermittently failed to come out properly when either door was used. the consumer took the vehicle to the dealer on 5 separate occasions and was unable to locate the problem. please provide any further information. *jb

The 2004 lincoln navigtor that we purchased has suffered numerous battery failures leading to various electrical problems. at first, the vehicle would not start at all. after numerous attempts to repair and over a week with the dealer, an improperly dealer installed dvd player was the cause. however, immediately after that problem was "fixed" the navigation system failed. specifically, the screen would "grey" out not allowing any input into the system. after 10-13 minutes, the options would appear for a few sections and then "grey" out again. *ak
