2002 Mercury Mountaineer AWD 4dr SUV (4.0L 6cyl 5A)
We have 2 and they are nothing but trouble. Transmission on both clunked so bad you had to look in the mirror to see if there were parts on the road. Dealer said it was computer calibration, but that did not totally fix the problem. Not the dealers fault, they received no technical bulletins from Mercury. Also we dislike the third row seat. Only small children could fit there. The seat doesn't fold down flat and should be optional.
Fix the transmission problem and make the third row seat optional. Get rid of the cheesy faux metal interior trim.
