heated seats are hot when i don't have the heated seats on

Heated seats are hot even when the heated seats are not on. I turn the switch off and on to no avail. When I ask the dealership to check the seats, they cannot find anything wrong. I have had people drive the car just to feel the heat coming out of the seat. Another Sonata owner with a newer is having the same problem!!

So many little things wrong with the 2011 Sonata, it is just crazy! Hyundai should be ashamed of themselves.
