We study the quantum corrections on the Szekeres system in the context of canonical quantization in the presence of symmetries. We start from an effective point - like Lagrangian with two integrals of motion, one corresponding to the Hamiltonian and the other to a second rank killing tensor.
Imposing their quantum version on the wave function results to a solution which is then interpreted in the context of Bohmian mechanics. In this semiclassical approach, it is shown that there is no quantum corrections, thus the classical trajectories of the Szekeres system are not affected at this level.
Finally, we define a probability function which shows that a stationary surface of the probability corresponds to a classical exact solution.
