Thanks for Replying
I bought the car, new, just before it started snowing here. I, too, just put snow tires on the care, but did not notice if it coincided with that. I will keep researching this and would appreciate you sharing anything you can find on it. First, I am going to run some "with" and "without" DS driving mode tests to see if there is a difference....with the hope of isolating it.
Thanks again, keep in touch if you find something.
