All of the D-Max motors use a common-rail fuel system with a Bosch CP3 pump ( CP4 on the new LML). The early ones (LB7) had such a bad time with injectors that the warranty was extended to 7yrs/200k miles. Tough to have to swallow a $1600 repair bill @ 70K.

I don't want this to come across the wrong way...but I'm glad we're not the only ones that get raped over injector repair/replacements.
Benny, I've heard some serous horror stories related to guys running the 6.4L & 6.7L when it comes to bad fuel and common rail fuel systems. I thought I wanted a 6.7L until I talked to a guy at my local dealership......

Iv been on the 6.7 forum to and that scares the Daylights out of me too
The 500 ponies stock would be GREAT But the rest of it IDK
then A guy cant even change those injectors M-Chane tells me they each need to be programmed specific truck
He also told me that to change that High press fuel pump on a 6.4 the cabs coming off
These 6.0s are the Last truck an owner could wrench and fix most things
there just setting them up Now so each Component needs to be programmed to the PCM when it needs changing so an owner can no longer work on there ride and has to Haul it in to the Dealer no matter what. I do agree that some things just better that the Dealer does computers and such but not stuff like injectors ect.....
Iv Just come to the conclusion I HAVE to MAKE this 6.0 LAST I can actulley wrench on this one for the most part (give or take a FICM or PCM failure) With the Help of the FTE and the Techs on here
The last couple of weeks in my fight to make this truck last Iv been crawling under it with rust remover and a can of rubberized under coating I did the oil pan and front axel so far and looks Great. Rust will be the Death of my truck if I just let it go

When a HPFP on a 6.4, 6.7 or a 6.6 has a catastrophic failure it's a ~ $10k repair bill.
There's alot of drama in the 6.7 forum over fuel quality right now!
An interesting feature on the Duramax is you don't even have to remove the valve cover to replace an injector.

Both systems have their flaws...and even some HEUI systems are better than others. IMHO the Cat (original) HUEI system is way better than the one we have on the 6.0L...but it has it's issues as well. I haven't worked on a Dodge or Chevy/GMC diesel truck...so I can't comment on them. I just know what I've been reading & hearing about the common rail'd 6.4L & 6.7L PSD. The shear costs for simple things are scaring the crap out of me.

(I know this one event doesn't prove anything BTW - just was amazed at the cost for 2 injectors)

Like Zhilton said ....it's all a matter of opinion and taste.
Everything will eventually have problems, Cummins, Powerstroke, Duramax....Honda civic's...some sooner then others.

Another interest of mine is Harley motorcyles, where there sure appears to be an effort made to channel all maintenance and parts through a dealer.
So, as a 70 year old Geezer, I'm hoping that my 04 6.0 and my 2005 Road King outlast me, because one of my pleasures is tinkering with mechanical devices.

LOL this thread reminds me of my dad and grandpa complaining about how crowded and hard to work on their new vehicles were when they started fixing their vehicles made in the 90's They went from a carburated motor that dident have much for emissions to a fuel injected motor that was starting to crowd the engine compartment with things like AC and emissions, and now look at things. So anyway if we take the 6.7 and compare the cost/reliability of the truck maybe things are not as bad as they sound. Yeah 10k is a huge bill, but if its a problem affected by less than 5% of the trucks under 300k miles they its not so bad. This is just an example I dont think they have been around long enough for us to be reading about 300k lol but soon.
