Abstract: Methods and systems are provided for operating a vehicle that includes an electric machine as a propulsion source. In one example, a motor stall assessment level is generated based on an amount of time that the motor is stalled and an amount of torque that is generated by the motor. Mitigating actions may be performed if the motor stall assessment level exceeds a threshold level or value.
