Well that didn't take long, GM is dumping the 3.0 current version for a newer one. Main cause seems to be long crank times and having to drop the transmission to replace the timing belt. Not a lot of available info yet but it's a start. https://pickuptrucktalk.com/2022/04/replaced-already-new-gm-3-0l-duramax-diesel-lz0-coming/
Looks like the 2.8 is dead too.

If they correct all the things speculated in the article, it could be a real winner. Now if they can do it without an EGR system it would really be a super winner.

Thanks for the information.

Attended Auto show in JAX this Spring. The 3.0 was in GMC equivalent of Tahoe and Suburban.
Closest option to my X in 17 years and there was a line waiting to experience the diesel.

I read on another site that the BabyMax (2.8) is gone for the Colorado/Canyon. They are only offering a single engine with multiple tunes to vary the HP/torque. No more 6' bed either.
