A fail-safe method and apparatus for high voltage parts in a hybrid vehicle is provided. In the fail-safe method, it is determined whether or not a high voltage main relay is turned off. Here, when the high voltage main relay is turned off, a voltage is charged into a direct current (DC) link using a counter electromotive force generated in a motor generator linked with a revolution of an engine. Voltage control is performed such that the voltage of the DC link is uniformly maintained using an inverter for the motor generator.
