I was not aware of the action you describe by BMW and I have not had any problems whatsoever with the M6's SMG. I can actually say that I like the SMG. It takes some getting accustomed to, and I agree with those here who've opined that familiarity with a manual or standard transmission helps with handling the SMG...particularly when it comes to things like sound and feel.
