We investigate theoretically and experimentally the instabilities of symmetry-broken, vectorial, bright cavity solitons (CSs) two-mode nonlinear passive Kerr resonators. Through comprehensive theoretical analyses coupled Lugiato-Lefever equations, we identify two different breathing regimes where components vectorial CSs breathe respectively in-phase out-of-phase. Moreover, find that deep out-of-phase can lead to intermittent self-switching components, spontaneously transforming a soliton into its mirror-symmetric state. In this process, are also sometimes observed decay. All our predictions confirmed in experiments performed an optical fiber ring resonator, CS symmetry breaking occurs across polarization modes resonator. To best knowledge, study constitutes first experimental report multi-component driven
