6D and EF 50/1.4 AF issue

Does anyone have this combo? I just got a new 50/1.4 but I got an erratic AF. At MFD, the AF is accurate - but for middle to long focus distance the lens is front focusing. I tried to compensate this through 6D's AF adjustment but it won't help. At times it's still front focusing - so it's rather unpredictable. One thing for sure, when I adjusted the AF, at MFD it's back focusing...This issue occurs even in good light. Is it the lens? or the 6D??
