It almost sounds like the tire(s) are rolling over on themselves. I checked the pressure when its around 0F, and it was around 27psi, so I doubt it would be rolling over. I have also had others watch for anything as I turn slowly in the parking lot, they hear it, but don't see anything, other then 1 guy saw the wheel jerk as he heard the noise.

I have taken it in to the dealer to have the noise, as well as a couple other things checked and will see what they say, assuming they will be honest about what they find.

In case you are curious, my other problems are:
Heated seats wouldn't go into High when it was around 0F, lights just flashed
Cigarette lighter doesn't stay depressed, tried new one and that didn't work, so problem is in the car.
Wind noise from passenger window.
Rubber plugs in glove compartment need to be installed in frame.

and my favorite, because of the "certified".... check my rear passenger tire for damage because I drove on it for 3-4 days with around 15psi (in heat, so around 10 in cold) because the dealer told me to ignore the TPM light, that he said would be on for a bit from being in the cold on the lot. Apparantly being certified doesn't require tire pressure to be anywhere near recommended levels.
