There are provided a motor control device capable of more surely detecting a short-circuit failure of at least one of a motor current blocking unit and a power source blocking unit regardless of a driving state and the like of a motor driving circuit, an electric power steering device, and a vehicle using the motor control device. The motor control device includes plural motor current blocking units that, in blocking operation, individually block energization between plural motor driving circuits and multi-phase motor windings of a multi-phase electric motor and an abnormality detecting unit that detects a short-circuit failure of the motor current blocking units. The abnormality detecting unit causes one or more motor current blocking units of the plural motor current blocking units to perform a blocking operation during energization between the plural motor driving circuits and the multi-phase electric motor, and, during the blocking operation, detects a short-circuit failure of the motor current blocking units caused to perform the blocking operation based on current values of currents flowing to the plural motor driving circuits.
