Same here, Michael. I bought my 50-135 second-hand in April 2009. I loved it so much that I bought my 16-50 new from B&H three months later. Both lenses spent a lot of time on the front of my K200D and K-5. I tried them on my K-1 last year, but I got obsessed with FF lenses. I brought my 50-135 out of retirement about a month ago to discover that the SDM was 99% dead. It had been getting a bit slow and hit-and-miss in late 2015/early 2016. My 16-50's SDM is still 100% (fingers crossed, touch wood, etc.) I sent my 50-135 off to CR Kennedy (Australia's Pentax importer) for some TLC. It wasn't the first one they'd heard of
I should get it back in about a week.
