Overall, this is a distinctly mediocre vehicle. I agree with other comments stating that the Xterra is a good value for money, but overall, the vehicle makes too many compromises to be a really enjoyable truck.
I seemed to have had more problems than others with my car. I live in Phoenix, and the truck seemed to have problems surviving our summers. All of my above mentioned problems happened in the summer months. On a related note, the air conditioner was a joke.
When my truck visited the dealership for these problems, there was always a back order for parts. My service rep told me that they had a recall on the window motors.
The loose skid plate and bumper were ongoing problems from my first summer on. Not a huge problem to deal with- when going over speed bumps, the truck would make a sound like metal hitting metal. Also made noise when going slowly on an unpaved road.
Performance was so-so, and fuel mileage was abysmal. I tend to put a lot of miles on my car, and my monthly gas bill was easily reaching $200/month.
I owned the car for 25 months, and I put 36000 miles on it. The Nissan Xterra is a relatively cheap way for someone to work a desire for an SUV out of their system.
