A controller for a hybrid electric vehicle executes an engine starting process when an execution condition for starting an engine is satisfied. The engine starting process includes a first starting process that drives a motor generator to crank the engine and a second starting process that is executed when the first starting process failed to start the engine. The second starting process includes suspending supply of power to the motor generator and then driving the motor generator to crank the engine. The controller performs a counting process that counts an occurrence of execution of the second starting process after the first starting process failed to start the engine. When the counted occurrence is greater than or equal to a determination threshold value, the controller prohibits operation of an idle reduction system of the engine even if the second starting process successfully started the engine.
