Have you tried multiple different objects/test charts with the camera to confirm the issue?
If you have the left AF problem, on the same target, the right bank will be able to achieve focus, and the left bank will lock but the target will be OOF. Since both right and left banks have the same sensors, and limitations, both should be the same. So if neither side can achieve focus on a target, it could be the target.
However, the left AF problem is not that the AF won't lock. The camera thinks it achieved focus, so it locks. There's no hunting, which is usually what happens when the target is not suitable.
This is most evident at wide angles and shallow DOF, so fast wide lenses are most impacted. However, the problem exists in all lenses, as I understand this, but it's not evident when stopped down or at longer FL's.
