To be fair to the OP, there are reports and anecdotes on this forum - and others - concerning real problems that users have had. Whether the various issues with Pentax gear exceed an industry average, who knows. We find reports of problems or failures in other brands as well, as recounted on similar forums. The overall rate of problems is relatively small compared to the total number of users, and not "everyone" has experienced a quality or reliability problem.
A newcomer or casual 'lurker' will find historical posts related to sensor stains, 'mirror flops,' battery issues, lost lens-release buttons, lens SDM failures, and firmware upgrade glitches. My own problems included a failed SDM on a 50-135 lens, and a mirror drive motor failure on a K-5 (both repaired promptly under warranty by Pentax Canada).
However, I now use a K-5 II, which seems to be very robust. Based on recent experiences of users, I think that Pentax (um, Ricoh) have resolved earlier problems of the original K-5 and other models. The current line of cameras seems to exhibit far fewer problems.
I would not hesitate to recommend Pentax cameras or lenses.
