Considering a 22’ burb or Yukon XL with a 3.0. Currently have a ‘21 burb z71 with 5.3 that’s in the shop again (lifters at 8500) now waiting on parts for air ride…going on almost 3 weeks . I don’t think the system is meant for rapid temp changes (went from 40 above to -20 in 24 hours before system crapped out) Am I a complete fool to try again with a 22 and 3.0 with no air ride??? I love the truck just not the issues. I knew about lifters but 3.0 dmax doesn’t seem completely trouble free either…
Fool me twice?

What's wrong with the DirtyMaxs?

They run on diesel
Look up long crank no start….there’s a few pages on GM forums. I know people with issues are vocal (me being one of them). I thought “the lifter won’t change my decision….” 8000 miles later and sitting with the fam 2 hours from home gave me pause.

The long crank issue does affect some LM2 Duramaxes. It basically cranks and doesn’t start, only very occasionally, and always starts on the next try. Nothing that’s going to strand you out of state or leave you without a vehicle for weeks at a time. Nor is it a ticking time bomb…
I personally haven’t had it on mine, and my dealer said if it isn’t broke don’t fix it. They have already come up with a software patch to eliminate this, which is a fix. There is no comparison the problems that people are having with 5.3 and 6.2 vs Dmax. By and large the Dmax platform has been fairly bulletproof and is the engine of choice in this vehicle platform…..

Well, I have the combo you're considering, and all I can say is that I've had zero issues with mine after eight months. No failure to start, no smells, zilch. That could change tomorrow I suppose, but so far I love it. I find it quite comfortable w/o air ride. Cruises quietly at any speed. About 24 MPG in daily driving and 28 MPG on the interstate if i keep it below 80. What do you give up compared to the 6.2? A little bit of acceleration once you reach 60 MPH or so and remember to add DEF at oil changes. If you just don't like diesels, can't help you. Otherwise as an alternative to the current problematic V8's, seems a no-brainer to me.

I’m thinking the lifter issue has more reported issues than any diesel issues out there, mainly due to the number of gas units sold vs diesel. Haven’t had any issues on my 5.3 thus far and sitting at 8500+ currently (May 21 build). If I do, I’ll consider the DMaX. I love this rig!!!
your build should be pre-lifter issue
