Hyundai says that the Sonata Hybrid is good for 36 miles per gallon in the city and 40 mpg on the highway, and the high-tech battery pack is only a portion of that story. The company's engineers have also rolled in a host of tricks to keep the fuel-economy numbers as high as possible, including what they call an "active air flap" behind that gaping hexagonal inlet in the front fascia. At low speeds, the flap is open to assist in cooling the gas engine, but once the vehicle speeds up, the flap closes to decrease the Sonata Hybrid's coefficient of drag by as much as 10 percent."

I had same problem "Open Active air flap system" i went to dealer and they told me the price of $1672 so i did not fixed there because the price is crazy high so i am still driving it i did 6000 miles on it since the light came on . Make sure you check if its open if its open not much harm but if its closed your in big trouble your will start heating up after a while and you will feel car starts messing up

If your flaps are closed just open them up by putting your fingers between them or use some kind of stick and pull down from top . If you don't know where are the flaps located just look thru your bumper grills . Also if you can afford a active air flap system for $150-$200 please buy it i bought my from eBay and if you need my help installation I'll definitely help it's very easy I did it by myself .
