There's no excuse for that kind of failure mode but it's pretty typical for Sturmey all through its history....
So 15,000 miles on my SA 5 speed (drum brakes) is an indication that it is not robust and won't last? Interesting view of the world you have.
Perhaps I am biased - so I googled "shimano IGH problems" 34,200 hits then "sturmey IGH problems" 9,800 hits.
I think if you explain the specific issues instead of throwing out generalized opinions you would come across as more helpful.
