Our 2010 had a hepvo valve (google it) on that drain instead of a P trap. It's usually located in the basement and can be removed by loosening the end connections. Do not run something down the drain or use anything but a soft brush to clean it or you will damage the membrane inside and have to buy a new one. We use a drain screen in the shower to catch the hair and keep the valve clean without having to do anything with it.
