As well as raw converter techniques of reducing or eliminating colour moiré patterns, there are also procedures using image editors such as Photoshop or Paint Shop Pro layers that can do the same, so for the few cases where it appears and might affect the overall image, I wouldn't consider it a big problem.

What do you think about what is happening around the blue Volkswagen? I can't figure out how that pattern got there in the K-5IIs photos.

As johnbee says, I think it is a pattern in the card stock on which the Volkswagen picture is printed, which the non Anti-Aliasing (AA) filter K-5 IIs can pick up.  I tried to remove the pattern using the pattern in the green channel but the moiré pattern is also in the higher-sample-rate green channel.  Perhaps techniques such as those of http://www.dbphoto.net/techniques/moire/index.html would work, but it's quite a bit of manual steps to go through.
