Not that I know of, but that system was the same from the old 12v. Already perfected and proven in the B series long ago.no doubt... they all have issues. cam blank softness issues wasn't one of them, though.
03-04 drop valve seats
04.5-07.0 tend to melt pistons more, but that may be a user error. In any case all 5.9s have terrible injectors and fuel systems.
07.5-12 terrible emissions system, tend to blow head gaskets, but that may be a user error.
13-18 have grid heater bolt problem because of faulty solenoids. C&Cs can drop valve seats.
Give a few more years, and the cam issues should disappear as they are rectified. But with the way things are going, there’s probably going to be very little R&D in this engine from Cummins, so we’ll see.
Thankfully, the aftermarket is strong for these trucks.
