A method and a system of controlling a powertrain for a hybrid vehicle which is configured to start an engine and use power from the engine even though a starting motor has failed. More specifically, a controller is configured to determine whether the starting motor has failed or not and if the starting motor has failed, a first clutch is engaged to lock a first planetary gear set to start the engine with power from the drive motor. Furthermore, while operating the vehicle, power may be supplied from just the drive motor, just the engine or both even when the starting motor has failed.
