When moderately/heavy accelerating in a low-mid speed somewhat tight corner, I can feel the car doing a hesitation like the tranny is slipping or the fuel is being turned off/on quickly. It will do this thru the corner until I back off the gas or the corner is gone.

Perhaps the Xdrive is hunting for the correct axle to power? I don't have ANYTHING close to tire slippage under these conditions, but I don't think the car is behaving properly when it has this issue. That is, I don't think BMW designed the system to feel like this when I get this power train feeling.

The car now has 40.5K and is under warrantee for a while. I want to resolve this before the warrantee expires. Any thoughts? Anyone else ever experience this?

Try it in Sport+ or DSC off and report back. Sounds like stability control intervening. You don't have to have wheel slip for DSC to kick in.
