6 whole years huh? most of my K M and A lenses are at least 30 years

Both my A50/1.2 and 100 f/2.8 macro have suffered failures. Obviously,
the more there is to go wrong with something, the more chance of failure
exists. There is really very little to go wrong with K and m series
lenses, and they are fairly reliable. A lenses had more opportunity for
failure, and are not as well constructed, on average as their predecessors.
The original SDM lenses were a product of Hoya/Pentax. Hoya had very
little interest in the camera division, and, as a consequence, very
little interest in the quality of the products, choosing to make them as
cheaply as possible rather than as good as was reasonable. The SDM
failures were a direct result of Hoya and their shoddy R&D and quality
control.
This is the main reason for why the recent buy out of Pentax by Ricoh is
a good thing. Ricoh seemed to want the camera division, something Hoya
never wanted, and made absolutely no pretense towards wanting.
