K-30 bought slightly used on eBay late January, 2013, manufacture date 2012:06:28.
Definitely has symptoms of "the dreaded aperture block failure", but I have not had that diagnosis confirmed by a technician; I am assuming that is the problem.
I first noticed the underexposed photos when shutter count was around 8986 (that is the oldest photo in my collection I can find quickly when I am certain the symptoms were manifested); that was just over a year ago, and I have seen the incidence of the underexposure increase. I had had no problems before that time that I recall.
I first thought it was the lens, because it seemed to occur only when using one lens -- the Sigma 70-200mm F2.8 EX DG Macro HSM II. When it started happening with other lenses, I was not sure whether to be sad or relieved -- at least the problem was not the expensive lens!
It at times seems to be worse / more likely to occur when I am pointing the camera down even slightly; I have not noticed any other tricks or tendencies with my particular K-30 body.
At this point, I continue to use the camera, though it is frustrating losing so many shots, and am considering the K-3ii or K-70 once I can save up some dough for one. It seems not worth the cost to fix. Sad, as my K-30 was an upgrade to my K-r, which had the problem front-focusing in tungsten lighting... from one problem child to another. I may just shelve the K-30 for now and use my backup, a K-x.
Thanks for starting this thread and for the survey.
I have not read through this thread, so maybe it's been suggested ... but my plea to Pentax would be to somehow offer those of us with failed cameras a coupon for $ off an upgrade, perhaps with a trade-in ...
