I didn't see in that link what the actual problem(s) is with the motor.

Wow, if they are buying them back that probably means no fix to the problem. Not good.

I don't understand why GM doesn't simply replace the motor.

Sounds like just new trucks. So considering no significant changes to that engine since 2017, must be a quality issue and not an inherent defect. Hopefully limiting the quantity of buybacks.
Hood this doesn’t put a damper on the 500hp+ version promised.

The only thing I can find was on a Duramax forum in comments on a thread. According to that, it seems to be a "heat treatment issue with the block that causes warping and hydrolock"
