Only the newest 2018, X15 engine did they somewhat reduce this fuel pump problem. You say your is 2016,.. Clearly a CM2350, and clearly in that category of "fuel pump of total engine death" category. Listen to the words of others on here and have the guts for the fuel pump changed by the time it gets 400k miles on it maximum (or equivalent ~roughly 8,300 engine hours?).
