The issue you describe is somewhat puzzling.
First: If the maximum aperture is 1.4, then it's a Summilux. Assuming this is the case, this lens is prone to focus shift at different apertures. Have it tested (it can be adjusted).
Second: Check the camera at infinity by focusing on the moon (if this is off you need to send it to Leica for adjustment).
Third: Check for front/back-focusing - Focus on something that will give you depth perception (like a chess board) with objects in front, middle, and back (about an inch or two apart) diagonally. Focus on the center piece. If this is off (you will know if it is), it could be the lens or the camera. If a problem exists here, a technician should be able to narrow it down.
