What was the cause of the failure? Was it something on the turbo or in the engine itself?

My cousin had one go down last week, (they have four in there group) the other three worked pretty good but all low miles so far.
Not sure what happened for sure. Will update when I hear.

Not the first of heard of this, had a N/A 850 in our group go down from crank failure as well.
Typical crank failure would point to lack of lubrication. But that really makes no sense, that 850 crank should have incredible lubrication, even considering that the throttle body injectors are trying to wash the oil off the lower rod bearing.
RGM: do you know which bearing failed? Was it the lower rod bearing by chance?

A guy in Sicamous is on his 3rd motor in a 2021 850T. About 4000 km. First motor went at 3000 km.

Update: motor ok, stator not so much, something fell apart or got inside the stator housing... maybe something lose from factory as less than 100 k on sled.

yes, this can happen but is not turbo specific all of the stator housings are open so you need to be careful dropping any nuts and bolts, rivets etc in the engine bay.

i had 2000km on my 2020.5 original belt before i sold.
i changed my belt at 2000km on my 2021 as i feel that is good life and do not want to risk failuire.
i have logged 4000 km between 2 different machines,
i never once said 3000km orignal belt

The clips for the shot can fall off and get into the stator, or anything left in the engine bay.

I don’t know the doo engine, maybe they should put a grommet or tape over this hole?? Dealer said it was a bolt that backed out inside??
