Only problem was fixed under warranty. Nissan redesigned brake rotors and replaced mine free. Very fast, reliable, all the bugs have been worked out. After owning it for 2 years, its still my favorite car to drive. I also own a vette convertible and G35. It is more quiet than the G35 and better for long road trips. I drove it to VT and drove in 6" of snow without problems. Great truck that I recommend to everyone. Get an '06 leftover if you can. The "improvements" for '07 aren't worth the extra money.
