Have had to replace engine twice.
Have had to replace coils for 2 cylinders at a cost $300 per cylinder.
Rust along bottom of doors.
Engine has quit running at highway speeds many many times, and dealer cannot diagnose anything that does not show up on his computer. Ford is aware of problems and suggests changing fuel.
$2500 fix to replace air conditioner because they have to take dashboard apart..
$1700 to replace pads and rotors.
Have 270,000 miles combined on my Volvo and Blazer and have not had 10% of the problems with these cars combined as I have had with the Navigator.
Poorly designed engine and worst dealer support.
These problems only cost you that much money if you take it to a dealer, buy a Chilton manual and a twelve pack spend a Saturday doing it yourself you'll save $1200 from labor alone. I have three navigators 1998, 1999, 2001 all with 100k+ wouldn't trade em' for anything bought an 03' Escalade sold it a week later.
