Trouble with a Titan XD

Better of getting the 6.7L Cummins. You get more power and there is not much of a difference in fuel economy. The only reason Cummins created the ISV5.0 was to make an engine that would fit into to tighter spaces where an inline 6 of the same displacement would have a hard time fitting into like cab overs and vans.

I've had good luck with Nissan in the past but the XD would have me leery. All new engine in an all new truck, and there are things about that engine I really dislike such as the timing chains and infamous CP4 grenade. I don't really see much in the way of advantages compared to getting the bigger Cummins in the Ram.

That would sure keep me way if I were researching whether or not to buy. That said, any brand can have an isolated lemon. The question with a relatively new model is "how isolated is this problem?"
