Do you see the same behavior with any other lenses? I've run about 30 lenses through testing so far and all have shown repeatable auto-focus. This has been against focus targets at relatively short distance though, not infinity. However, I just got back from a trip with about 2,000 images, still sorting through them but so far I see no focus issues with any of the lenses I used.
But I don't have the 15-30 so not sure how much all that helps you.

What AF mode are you using? Try single center point, called 'spot'. Press and hold the button marked AF mode then rotate the rear dial.

I think almost everyone else with the k-1 has been ecstatic over the great auto-focus, so your experience is clearly an exception. Whether that is due to a faulty camera, camera settings or your not being used to small DSLRs remains to be seen.
The obvious thing to check is what focus mode your are in. If you have it in AF.S and spot then your focus should be repeatable, mine certainly is. If however you are using Auto multi-point or Select multi-point then the camera has a number of focus points to use and will select the one it thinks best, which in many situations will not be the same one as the last time due to changing lighting, very slight movement of the camera and so on.
So to see if the camera is faulty, put it in AF.S and spot (single point) mode. Put it on a tripod and test the focus, it should always give the same result. If it is still giving inconsistent results I would suggest returning it as defective as this is not normal behavior.
