The axion solution to the strong CP problem is closely entwined with the flavor structure of the standard model. So our model attempts at explaining the Flavor puzzle through the Frogatt Nielsen mechanism where the flavor symmetry is gauged and we thereby end up with a "quality axion" as the result of a residual symmtery. This is achieved in a DFSZ like scenario with a "Flavon" field of the gauged in addition to the PQ scalar. We find that, demanding a favorable mass texture compatible with embedding, the charges we require to cancel the anomalies naturally provide us an accidental quality axion whose scale is connected to the scale of right handed neutrino mass making it a viable ``Majoraxion". We also analyze the flavor violating (FV) axion phenomenology to test the model at the E949, E787 and CLEO experimental constraints on the FV vector axion quark couplings.
