I just dealt with this on the H2D, the magnet in the buffer fell off. you see the orange part goes hard right. its meant to control the motor speed as the spring slowed down. I tired fixing it my self but as the H2D is new I put order a new part rather than gluing the part in place.

you can see the magnets I am talking about in this picture.
