I have been driving Ford products since 1989. My current Mountaineer has been the worst of the lot. The other 6 or 7 did fairly well. All models lasted over 200,000 miles with only 1 transmission being replaced in the mid 90's.
My 02 Mountaineer
Wheel bearings (which are not serviceable and require a new hub up front) only last a couple of years then they go out. I've replaced 7 since 2002 and I have one bad again.
Transfer case has been replaced.
AC condensor replaced.
Most of the plastic hoses under the hood have cracked.
Multiple sensors including MAF have been replaced.
Ball joints have cracked boots and need to be replaced.
Interior trim pieces on all 4 doors are broken - all exactly the same place.
Entire window mechanism in passenger front door replaced due to small plastic clip breaking.
Steering wheel leather fell apart within the first year and they replaced the steering wheel with a cheaper Explorer model which has held up better.
Gear selector is wearing out, I have to shift into P or D in 2 stages as one of the plastic pieces is very worn.
Seat heater blows fuses regularly.
Plus lots more that I cannot remember right now.
Other than the above it has been a nice vehicle
Actually I do love the truck. The 4.6 AWD V8 is a geat combo. Plenty of power and the AWD is fantastic. I have owned a Subaru for 10 years so I know about AWD. Fords are very comfortable, ride nice and feel like an old shoe after a while.
I will miss it. Shopping for a Range Rover HSE Sport right now. I am a gluten for punishment.
