The nuclear recoil effect on the ground-state g factor of highly charged boronlike ions is considered within the relativistic formalism. The interelectronic-interaction contribution is evaluated in the Breit approximation, employing two independent approaches: the second-order perturbation theory and the configuration-interaction Dirac-Fock-Sturm method. The uncertainty of the nuclear recoil g-factor contributions is significantly reduced, especially for low- and middle-Z ions.
