Other board members, chime in, if I'm not accurate here.
Your email didn't mention if you tried to get "unstuck" with TCS engaged. TCS and AWD work seemlessly and there are no "indicators" that show when power or what percentage of power, is transferred to the rear.
Sometimes, all of this technology fails us. You only disengage TCS when other options fail. In the old days, before 4wd/AWD, if one got stuck in snow, one way was to rock the car, back and forth, by repeatedly shifting between fwd and reverse. Such is true with the CX-7, IF you disengage the TCS. TCS automatically senses loss of traction, then applies power to the rear axle. If AWD doesn't pull you free, you have to try the old fashioned methods.
BTW, CX-7 is basically a very light-duty off-road vehicle. It wasn't designed for extremes, so don't put too much confidence in the CX-7 to pull you out of a jam. Here in northern VA last winter, we had one pretty good snow storm and dumped about 1.5 feet snow is some spots. My CX-7 handled all of that with ease and I was bookin' down the freeway, when other drivers were ploddin along at 15 MPH in the slow lane. Here I was, troopin' along at 45 MPH ! I WAS IMPRESSED!

Correct. He should have left the TSC on. Even so, only 50% of the power will be delivered to the rear.
My father in law has had no problems driving in the snow.

I wonder what condition the tires were in?
For my wife's new cx-7, I will buy winter tires. In massachusetts, they are worth having. Not mandatory though.
#5 of 9 tried TCS off and then on

thanks for the responses to date. I actually tried both TCS off as well as on. Neither seemed to make any difference to the rear wheels getting power...
The tyres were new (the car was only 1 week old!) and were the Goodyear RSA mud and snow...

you might want to check the performance of the tires at tirerack.com. They evaluate tire performance in various conditions.

Something is not working correctly. I would take it back to the dealer. Power should have sent to the rear wheels--at least a certain measurable amount of it.

I drove an AWD CX-7 through last winter with the standard Goodyear all season tires and it drove excellent with no problems. Your Massachusetts winter should be roughly equal to our Minnesota winters, so I feel that snow tires should be unneeded on this model.
