We calculate here the kinetic-energy release distributions of fragments produced for electron-impact dissociation of the vibrationally excited molecular hydrogen ion $${{\mathrm{H}}_{2}}^{+}$$ and its isotopologues $${{\mathrm{D}}_{2}}^{+}$$ and $${{\mathrm{T}}_{2}}^{+}$$. Here we apply the adiabatic-nuclei convergent close-coupling method and compare results with several different methods, including the $${\delta}$$ approximation. Results are presented for a number of dissociative excitation transitions and dissociative ionization as a function of the initial vibrational state of the molecule. We confirm that the square root approximation is a good approximation for the adiabatic-nuclei kinetic-energy release cross sections of $${{\mathrm{H}}_{2}}^{+}$$. Agreement with experiment, where available, is good.
