Had an interesting failure on a truck at work, 2012 Silverado 4.8L V8 / 4L60E auto with about 180K miles on it.
It has been making a knocking noise for a while that was suspected to be the flywheel...found out it for sure it was...
The driver said there wasn't any real noise when it happened, it just stopped pulling as he was going down the interstate. He pulled over and it was still running, but the AC cut off, so he turned it off and tried to restart, and nothing. It took out the starter pinion too.
Reman starter, new flywheel, and a trans mount and it's back on the road. Amazingly no other damage. The guy who usually drives the truck is not abusive, but some of the previous operators probably were.
