Q: Can you help me determine why my engine check light is triggering? on 2011 Hyundai Sonata

Car has less than 9000 miles and am getting a P0455 obd code. Seems to me that there is a serious defect somewhere since I would not expect the engine check light to appear on such a new car. No noticeable negative impact to performance and I don't smell any gas fumes in or around the car. Any advice would be appreciated. Hopefully this is covered by the warranty. Thanks
