A method for preventing secondary overvoltage-breakage of a hybrid vehicle comprises measuring the temperature of a motor and determining whether the measured temperature exceeds a predetermined temperature at which an over-voltage is induced; performing an energy consumption control logic, when it is determined that the measured temperature exceeds the predetermined temperature, by a mode of increasing charged energy of a 12V battery or by a mode of allowing a 12V electronic component or components to consume energy; and stopping the performance of the energy consumption control logic, when it is determined that the measured temperature does not exceed the predetermined temperature. The method can prevent induction of an over-voltage by regenerated energy in a fail mode in which a main battery is disconnected with high-voltage components.
