  Li\'enard-type nonlinear one-dimensional oscillator is quantized using van
Roos symmetric ordering recipe for the kinetic-like part of the new derived
Hamiltonian. The corresponding Schr\"odinger equation is exactly solved in
momuntum space via the approach of supersymmetric quantum mechanics (SUSYQM).
The bound-states energy spectra and corresponding wave functions are given
explicitly in terms of the ambiguity parameters. The limiting case of no
deformation agrees exactly with the eigenenergies and eigenfunctions of the
ordinary quantum harmonic oscillator.
