Render with an override material, if the spots go away you know it is a material that is causing the problem.

are you using an HDR image to illuminate your scene?? if so try to increase the resolution in your Dome light or apply a little blur to your image, also the samples of your GI seems low, can you post your light and GI settings?? maybe then we can give you better input.

Was the problem solved? Please update us. I sometimes have similar problem as those that has been posted here before, but the original poser never bothers to update what worked for them. Saves us the time to narrow down solutions.
