I've got a 2012 Hybrid HL and noticed the same thing as well, my findings might be related to your 2011 model.... I put it down to the heater vent pipes running through the console for the rear vents. I worked this out as I have dual climate, so tweaking the temp on each side of the car adjusts the temp of the console. Being its 'winter' atm, the heater is running so I think you are noticing its warming up the console. If I flick the temp right down on the passenger side, that side of the console gets cold, while mine says hot. The same if I ramp the temp right up, that side gets hotter than mine and vice versa on the drivers side if I ramp the temp up or down! So seems its just routing of the climate pipework that is causing it. I do agree, it can get very warm!!
