I live in southern Illinois, near St. Louis. I bought a grey 2012 SV 4x4 with 149,000 miles on it in the beginning of December. I've put almost 3500 miles on it since. I'm using it to drive in the snow, haul the family, and tow our 18" boat. I've changed most of the fluids in it because I don't know when/if they were done.
1. I noticed about a month ago that it started making a tapping/clicking noise at cold start up. I can't hear it after I drive for a few minutes. Is this a common issue with the VQ40DE? I hope its not the timing chain guides starting to fail
2. The rear AC sometimes makes a clunking noise when its changed from cool to heat. I'm going to remove the trim panel and try to find the problem
3. I'm disappointed in the fuel mileage. I've averaged about 17.5 mpg with more highway than city driving.
Overall, I think its a great truck. The issues are all minor at this point. I'm encouraged by the other high mileage Pathfinders I've seen of this vintage.
