New nondiagonal $G_{2}$ inhomogeneous cosmological solutions are presented in
a wide range of scalar-tensor theories with a stiff perfect fluid as a matter
source. The solutions have no big-bang singularity or any other curvature
singularities. The dilaton field and the fluid energy density are everywhere
regular, too. The geodesic completeness of the solutions is investigated.
