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

Unless you are over 36,000 miles it is covered under warranty.

Doesn't your Hyunday have a TEN year or 100,000 MILE warranty?
The ten/100K is just a powertrain warranty. The 3/36K is a bumper to bumper warranty. The bumper to bumper warranty covers everything.
Parts Guy,

Thanks for the info. Appreciate it.
