The issue below appears when smoothing in maya. I would prefer to solve the problem normally as opposed to import/export obj.
Below the image is a .ma file you can download yourself.

Steps Taken To Isolate Problem
-Issue does not occur when doing a smooth mesh preview with the EXCEPTION of 1 face
-Deleted face. Error moves up another face.
-Continued to delete the face ring one face at a time and noticed the error moves up.
-Selected face ring, delete and rebridged. Fixed.
-Infered that the root cause of the problem has something to do with the way I created face ring or edge ring.
-The issue only occurs in this one mesh object.
-Deleted all items in the scene except the problem mesh and saved an isolated file.
-Deleted UVs.
-Deleted history.
-Optimized scene.
-Cleaned mesh with the following settings.
-Select matching polygons.
-Apply to selected objects, Keep Construction History.
-Lamina faces.
-Nonmanifold geometry, Normal and geometry.
-Merged all vertices with a tolerance of 0.01.
-Unlocked normals.
-Ensured normal directions were correct.
-Ensured there were no faces inside of edges.
-Issue ONLY occurs with 1 subdivision.
-Hardened all the edges.
-Exported and reimported OBJ. Again, I do not want the lazy solution, I want the correct one. I did this so I can infer that the root cause is not mesh-related.
-Combined with cube
-Deleted history (again)
-Optimized scene (again)
-Cleaned mesh (again)
