Aviator 8-cyl

  • 130,000 miles


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!
