You mean the runaway mirror syndrome that was present in the early run K-3? That issue was addressed in production Summer of 2014. Reports after Fall of that year have been fairly sporadic. I can't make a strong general statement, but I don't believe the more recent reports have involved recent purchases from reputable dealers. Unfortunately, it has not been easy to characterize the risk by serial number range. Even so, I would expect that any K-3 made after August 2014 would be safe for that issue.
The only other common complaint I have heard regarding the K-3 is camera "freeze" or lock-up. The user will be using the camera and it will suddenly become completely unresponsive. The immediate remedy is to switch the camera off and remove the battery for 30 seconds or so and then replace the battery. Mine has locked up a handful of times since I purchased in Spring 2014, but not in the last year or so. I am running firmware v1.11. The has been speculation that the lock-up problem is power-related, though I was not able to make that association in my case.
Note that the K-3II, while very similar, is not the same camera as the K-3. Both hardware and firmware are different between the two cameras to reflect the difference in features.

* The percentage of users affected by the runaway mirror mirror issue has been difficult to determine. As for other problems, I did a quick tally of posts on this site regarding K-3 problems/complaints and found only two in September that involved recently discovered camera defect.
