The problem is that they probably will never admit it, so we'll never know, and the "perception" then is #2
"then you are saying "Pentax is evil" is a bit dramatic, don't you think?
No, when people make the same complaint over and over again, that is exactly what they are implicitly saying.
I cannot imagine sticking with a company when I don't trust them. I had two Canon Rebels in a row fail me, each apparently having processor issues.
It took me seven years to get there, but only 3552 shutter clicks - 2913 unique pictures according to my count.
I had moved from Pentax to Canon in 1995 because I liked the Canon lenses better, but in 2015 I moved back to Pentax because I decided I couldn't trust Canon bodies.
I am now using a K-30; I hope it doesn't fail soon {current shutter count 1454 - 538 unique pictures}, because our bank balance isn't what I would like it to be, but several M42-mount lenses now reside permanently in my camera bag
I keep asking questions about this malady because the answers I get don't point me in the same direction; I'm currently using my K-30 with AA-batteries and I try to use it at least once each week, because comments seem to indicate that these two practices might help ... but I don't know, and I don't believe that the Pentax engineers, who are a lot better at this than I am(*), really know.
The K-30 was released something like 4-1/2 years ago; if you assume that it took at least a year for this problem to show up in sufficient numbers to convince Pentax that it wasn't a fluke, and another year at the other end for the K-70 and KP to be designed. Pentax spent maybe two years trying to figure out what was going on here before giving up on that mechanism and moving on. As long as they have honored their warranties, as a retired design engineer I believe they did the best they can, and I can't see sinking Pentax over the cost of providing infinite warranty-like protection over something they had no way of foreseeing and no obvious way of alleviating.
(*) I am now retired, but as a software engineer I worked with some very clever hardware engineers, including at a company that makes lab equipment and an aerospace company, so I have high respect for the kind of person who does that kind of work.

Originally posted by paolo11 The problem with Pentax repair (Precision in CT), is that they replace the entire aperture block. The question is: modified or original? Why doesn't Pentax come out and say what the problem is, and how they are repairing it so we all can stop guessing.
As I've said multiple times, I'm convinced that they don't know what the problem is. They were caught by surprise when it started happening and after a couple of years trying to understand it, they gave up and moved on to another mechanism for the K-70. I would love to get a K-70 if I could find money for it.
