Just bought a 2011 AWD non-turbo Flex. So far ,so good. Have owned it about a week and noticed that it seems to slightly hold back when the traction control is on and descending a hill. I noticed it doesn't seem to roll as freely down hills as my old minivan. I almost have to give it a little throttle on descents where I was dragging my brakes in the van. . I turned the traction control off and it seemed to do better. Not sure if I'm imagining things or not. I know the traction control is only supposed to work (or do anything) when wheels are slipping. Any one else notice this? I will try and get better data as I drive it. I'm also wondering if the fuel mileage will be affected when I don't need traction control.

You are imagining things. Traction control has nothing to do with going down hills. The Flex uses a system called ADFSO which shuts off fuel while going down hill, that's why it doesn't roll as freely. It's one of the technological advances that helps Ford (and others) improve the fuel economy on the newer cars. But the traction control system will have no effect on fuel economy in any way, unless of course you want to sit and spin your wheels for minutes on end.

Or did he push the button on the shifter?

Is there a hill descent feature on the 11? I dont recall the 10 I had doing that, but it was also an Ecoboost.

Yes, they all have hill descent.  On the Ecoboost if you put the shifter is "M" or "S" on the new one it will be in hill descent mode until you use the paddle shifters.
