Seized Engine UOA - Proving shop damaged my engine

OR-it could be these (diesel) vans are absolutely garbage-because they are.

Yeah they're honestly bad. Frankly there's almost no diesel vehicle that I would buy over something with a big gas engine unless I absolutely needed a pickup truck to tow 15k+ lbs routinely. But I would never buy a car or suv with a diesel these days. I was first offered a 3.0 V6 duramax Escalade before buying my 6.2 one but I declined on it because I had a gut feeling it was going to be a piece of junk and it's designed terribly when you look at it. Now gm is discontinuing it and I'm for it.

My Son managed a small fleet of these. The reliability was low-and the repair costs ultra high. They got rid of them in favor of gas version.

Wouldn't surprise me if they fired it up after the job without oil by accident, figured it out quickly, then added oil after the fact. Just a wild guess. Probably also impossible to prove.

Q- was the oil/water heat exchanger leaking coolant in oil for a while before the repair? That in itself may kill the bearings over a couple months time

This is something that has me curious as well. Coolant/water in the oil will wipe out bearings which the shop would have no way of knowing unless they drop the oil pan.
