Do you have the A/C also turned on? MAX A/C switches on both fans I think. Maybe not in the 2011's?
Another reason is A/C system charge/sensor. If the system has incorrect pressure, or if the pressure switch says it does (faulty sensor), it triggers the fans on.
Others will have to help on that, I think it is the high side pressure switch.

Fan's don't run on high speed just on A/C alone do they? I thought it was only MAX A/C.
There are a few things that cause the high speed, including error sensor readings.
You should get codes read, it is likely there is a stored trouble code. It's odd that there have been 3 threads in 3 days with this problem all of a sudden happening. Maybe it was 3 threads in 4 days.
