Robteesit, What you're describing is the traction control (VDC) doing its thing. It senses loss of traction and limits engine RPM and just about all wheel spin. If you try to go up a hill covered with snow and start spinning, this will kick in and you won't make it. This is where you need to turn the VDC button to "OFF", and, most likely, the AWD to "ON" (if equipped). See manual excerpt below:

Durning the big snow here on the east coast of 2009, and after the plow pushed a big mount of snow in front of the driveway. I went to back out and the car seemed too just stop when it encounter the resistince of the snow in front of the driveway. I was backing out slowly and just got into the mount of snow and the car just stop accelerating? No wheel spin, no engine rev or anything - just quit going in reverse. I could move forward no problem and then when I backed out in reverse again, giving it move gas, it bounced over the mount of snow and then all was fine. Never experienced anything like this before - it was almost like the car was not in gear - but it was even stranger, because when I pushed the gas pedal down nothing happened, no increase in rpm's or noise? It hasn't happened since and if I remember I will ask the dealer about this when I take the car back for the recalls.
