We propose a D4 flavor model based on $\mathrm{SU}(3)_C\otimes \mathrm{SU}(3)_L \otimes \mathrm{U}(1)_X$ gauge symmetry responsible for fermion masses and mixings in which all fermion fields act only as singlets under D4. If a $SU(3)_L$ Higgs triplet, lying in $\underline{1}'''$ under D4, is regarded as a perturbation, the corresponding neutrino mass mixing matrix gets the most general form. In this case, the model can fit the most recent data on neutrino masses and mixing with non-zero $\theta_{13}$. The sum of three light neutrino masses and the effective mass governing neutrinoless double beta decay are obtained that consistent with the recent data.
