The results of $$^{27}$$Al nuclear magnetic resonance and specific-heat measurements of the noncentrosymmetric superconductor Mo$$_3$$Al$$_2$$C are reported. The phase transition around 130 K is inferred from a distinct change in the NMR spectrum, a clear peak in the spin-echo decay rate, and an anomaly in the specific heat. Possibility of charge-density wave ordering around 130 K is discussed by calculating the Fermi surfaces in the normal states and considering the partial quenching of the Fermi surfaces with the decrease in 1/$$T$$$$_1$$ below the superconducting transition temperature.
