Generalized Hidden Local Symmetry (GHLS) model is the chiral model ofpseudoscalar, vector, and axial vector mesons and their interactions. Itcontains also the couplings of strongly interacting particles with electroweakgauge bosons. Here, GHLS model is confronted with the ALEPH data on the decay$\tau^-\to\pi^-\pi^-\pi^+\nu_\tau$. It is shown that the invariant massspectrum of final pions in this decay calculated in GHLS framework with thesingle $a_1(1260)$ resonance disagrees with the experimental data at anyreasonable number of free GHLS parameters. Two modifications of GHLS modelbased on inclusion of two additional heavier axial vector mesons are studied.One of them giving a good description of the ALEPH data, with all theparameters kept free is shown to result in very large$\Gamma_{a_1^\pm\to\pi^\pm\gamma}$ partial width. The other scheme with theGHLS parameters fixed in a way that the universality is preserved and theobserved central value of $\Gamma_{a_1^\pm\to\pi^\pm\gamma}$ is reached,results in a good description of the three pion spectrum in$\tau^-\to\pi^+\pi^-\pi^-\nu_\tau$ decay.
