This is the worst review that I have seen so far on the Titan diesel. I hope that it is an isolated case: http://www.caranddriver.com/reviews/2016-nissan-titan-xd-long-term-test-review
I wouldn't waste my money on a half ton diesel truck, go all in or go gasser.
Zero issues with my previous 2011 diesel in the 110k miles I had it and so far I have 23k miles and zero issues on this one. I don't think you can drive the new diesels around town, they need to be worked and run for a long time to keep from clogging.
