general problems of the 2004 Lincoln Aviator

My SUV misfires, slips in and out of gears, stalls at stop signs and lights, accelerates at stop lights. Occasionally when the ac is turned on, there is a very loud clunk sound.

I purchased my truck used in December 2011 and it has been nothing but constant problems. First, the door locks would randomly engage/disengage on their own. Or if button pushed nothing at all would happen. While the heater works, it emits a death rattle before blowing air. My ac doesn't work at all and was told that I would need to replace the compressor. The most dangerous and expensive repair has been replacing the front differential mounting and wheel baring. I was told that it was only mounted on one side and was leaking and this was a common problem with this model car. The mechanic was actually able to shake my wheels with his bare hands. The front end stuff actually dropped from under the vehicle as I as driving. Luckily I was able to safely pull over and had to be towed on a flat bed because the front end was so damaged. Repair costs $1400. And I was advised that it would probably happen again! prior to this I also had to replace the wheel bearing and ball joints. Ford does not stand by their product!.

This is the 3rd time that my 2004 Lincoln Aviator has shut down while driving it. . . With kids in the car. No steering, no breaks, and 60 mph down the highway. This car is sure to be the death of me. . . I have been lucky 3 times now, but what about the next time??? voluntary service recall. . . Manufacturing defect of the coil packs. . . Issued by epa. Gov (found after digging), replacement of the coil packs are covered until 120,000 miles. Ford will only replace one at a time, not all of them, so each time one is replaced. . I still have the risk of another going bad. Had four replaced so far, another tomorrow. I cannot believe that Ford can get away with this knowing that they are putting people's lives in danger. A car completely shutting down while driving at 60mph because of a defect during the manufacturing process doesn't cause concern for a recall. . . But a car speeding out of control does? what happens when I am on the interstate next time during rush hour and I have no steering or brakes????.

Early this morning was driving on the freeway in our 2004 Lincoln Aviator. There was a moderate rain fall and zero natural light was available. Without warning, the electrical system, including the headlights, in the vehicle shut off. I was traveling at approx. 70 mph and was carrying a total of seven people. Unable to see, I drove off the road and was horrified to discover that I almost ran into the guard rail. While this situation did not result in any damage or fatalities, this could have easily been a disaster resulting in multiple deaths. I spoke to the local Lincoln dealership who to my surprise, indicated that he was aware of similar behavior on a similar Ford vehicle. Apparently, a leak in the windshield seal can direct water into the engine compartment and into the primary electronic control computer. I am taking the vehicle to the dealership for further investigation, however, this problem is intermittent and will therefore be very difficult to diagnose. This problem occurred another time a few months back, but the electrical system came right back on so we did not attempt to diagnose the problem. I am particularly concerned about this problem because it could have been the cause of multiple fatalities and the cause could have easily been attributed to my falling asleep at the wheel. Please do something about this important problem. Thank you.
