This shudder (IMO, it's more than just a vibration) has nothing to do with ice or snow build up in the driveline or wheels. The best way I can describe it is it's like driving a car with a manual trans in too high of a gear; it's like you're lugging it to death. I took one out when it was -15F and it felt like the engine was about to drop out of the thing. The only remedy for this in the meanwhile is to manually shift the car down a gear when it starts to shudder.
From what I've been told Mazda USA hasn't given us much to work with so far. We've been told they think it's the liquid motor mounts (and from my experience, I believe that to be true.) I wouldn't be surprised if the fix would be an ECU update to raise the shift points when the car detects extremely cold temps. Much, much cheaper than replacing motor mounts.
