This is the most reliable vehicle I have ever owned. Bought used at 47K miles and now have 90K. Didn't know warranty went to 70K but never needed. Traded in a 2002 Odyssey for this QX4 and had a volvo wagon before that. No comparison. This truck is great on the highway, safe in the snow and good offroad (think skid plates and real 4wd). The important difference from the Pathfinder is the Nissan Skyline transmission and extras. Real gas milage is consistent 19MPG. Good trailer towing capacity.
I have owned this vehicle for 3 years. It is great to drive, has loads of cargo space, is luxioursly comfortable inside and has a dynamite Bose system. It is well insulated from road noise, drives crisply and rides well. If you can find a clean one, go for it. It has all the bells and whistles you would expect from a luxury SUV. I was looking for a 4Runner but found this sitting next to it. Wasn't that impressed with the Toyota, but fell in love with the QX4. It only had 7500 miles on it. Now has 35k.
This vehicle is wonderful. It has everything, and is affordable. Could use a little more power, but not that bad. Better than what I expected. The comfort is great, and the Bose stereo is incredible. I highly recommned this vehicle.
I have to honestly tell you, that I really Love my QX4 and it is very very dependable with no repairs so far and it so sturdy on the highways. I love to drive this SUV on the highways since the seats are comfortable and the car rides very smooth and is very easy to handle. The styling is unmistakably luxiurious as it was the first luxury suv and the build quality is fanastic. I highly recommend people to buy these QX4s as well as the all new Infiniti FX35, because these SUV have a great reliablity, fun-factors, styling, and a decent price for what they offer.
Bought it used with 109K miles in 2007. Overall a very fun car to have and drive, wonderful comfort, great sound system, great off-road. There is one very important limitation - bad fuel economy, about 12-16 MPG. Which means it is not for a lots of freeway driving, but rather for short commutes, small towns and off-road (which is excellent!) Some reliability issues - non specific, but after 100K miles, some small and not small parts tend to go out. Off-road as good as it gets. I drove on a very steep uphill, narrow winding mountain road with more than 6 inches of snow and ice, and it went right through it for miles until the snow got really thick (more than 10 inches).
