I have '12 6.7 PSD with ~60k miles. So far it's been a great truck that makes really good fuel economy. Not one single glitch, CEL or a trip to the shop like the other brand seams to be experiencing right now.
The updates on the '15 trucks are basically for increased HP/torque to smoke those cummins boys....Although my current truck will do that all day long! :B
They did make some changes to the problematic fuel pump, as referenced by earlier posters.
Now what exactly they did is not known to me.
For your reference brnzbk, all three brands (Ram, Ford & GM) run Bosch made fuel injection pumps.
Ram runs with the Bosch CP 3 series pump.
Ford & GM run with the Bosch CP 4.2 series pump. The first version of this pump came out with the 2011 Ford 6.7L Powerstroke and was later also adopted for use in the GM Duramax engine.
The problem area with the Bosch CP 4.2 pump seems to be in design. A twin piston V design, it will run at twice the RPM's of the engine in order to deliver fuel. But, for some reason, Bosch built the pump
without wrist pins connecting the pump piston to the connecting rods.
And, in rare cases (Ricatic's, who previously posted here was one) the pump piston separates from the connecting rod and the resulting collision between parts sends aluminum shrapnel throughout the fuel system destroying the engine.
It may indeed be this wrist pin that was changed/or added to the revised 2015 but I do not know for sure. I do hope this is the case, because it would really add to the reliability of this engine.
I owned a 2011 Ford, and it served me well without problem. Many have put literally hundreds of thousands of miles on this motor, without problem.
But there are some who have had the fuel pump problem. In this small group of folks who post here on this forum, there are two who have had their fuel pump destroy itself. The aforementioned Ricatic and a Canadian poster whom I will not identify publicly.
To conclude, I would also urge you to go with the 2015 Ford if you are leaning towards that brand. As mentioned, the fuel pump in the 2015's was changed somewhat. Hopefully, it will eliminate the problems found in a few of the earlier version pump.
