This was a known issue with the k-5. There would be quite a few threads about it here someplace.
I forget the exact term, maybe it was the "mirror actuator" or something like that. For awhile I just just smacked the bottom of the camera when mine got stuck, worked quite well, (but not recommended)
Anyway, it will gradually get worse and does need repair to fix. Mine was done under the extended warranty so no cost to me. You will need to decide if it is worth the cost of repair or if it is time to trade it in.
