third time lucky?

I have now taken possession of a clean K5. Yay! Went out with it yesterday to the Seven Sisters. Trouble is, that has highlighted how inaccurate the inbuilt electronic level is. As it is a feature of the camera, I would like to use it. Not sure what to do though, I am not having a good run with the K5. Do I take it back for exchange, take it back for warranty repair, or ditch Pentax completely? Having to go go into a shop and say “I want a Pentax, but this is the list of know problems that might mean I bring it back…” is just a bit embarrassing. It also highlights that the decision to stay with Pentax is not really that rational. Anyway, the pictures were good and the camera handles well, but that just confuses the issue.
