Since setting it to 70 gives you warm air, there's obviously enough heat to go around. A defective thermostat would show as the temp gauge barely getting off the peg.
I'll bet that if you put a thermometer in the car, you'll see the temp fairly stable. 66 degrees is actually pretty cool. 66 degree air blowing on your skin would feel even cooler. At highway speeds, you've got more air flowing through the car, so essentially, you've got a 'wind chill' effect.
The ACC tries to do a good job, compensating for solar gain (sun sensor in dash), but it can't adjust for humans. I've run into this - in summer, 70 degree air blowing on my skin would feel cool, and in winter, 70 feels warm.
I don't think there is anything wrong with the ACC. No system is going to feel totally comfortable until instead of a dash sensor, it gets wired to your brain. The best you can do is set the temp a little higher.
Remember the old days, when if you were cold, you turned a knob on the dash to adjust the heat?
