2018 2500 Factory Clutch Fail

[sag2]

Update: Truck back
Replaced: Flywheel, Clutch, pressure plate, release bearing, pilot bearing and all the hydraulics including the master cylinder, i.e. everything.
The bottom line is that this was either damaged or installed wrong at the factory. They found damage to pressure plate fingers, heat checking, and a worn flywheel.
On their first test drive when i dropped it off, they could not replicate the problem. So i told the service manager to drive it himself and told him exactly how to reproduce the issue. When he did the following day, he said the clutch was slipping so much he was worried that he would make it back to the shop, after climbing a large hill. My guess is that he finished it off.
I prefer manual transmissions, so my other truck is far from the only standard i have owned or own and have always had fantastic longevity in clutches for the vehicles i drive. The extremely strange part of all of this is that there was no burnt clutch smell, no missed shifts, no slipping from a dead start, only at speed.
Again, just posting the painful details to help others should they see something similar in their rig.

Sounds like the technician had no clue how to diagnose the problem. Replacing everything was a waste of money and tells me that they have no clue as to the root cause of the problem. That doesn't really help anyone.
