Ocassionally when coming to an almost stop in "D" mode. I can feel a thud under the floorpan somewhere. Its more of a sensation than a sound, as if someone tapped the floorpan with a rubber mallet, but faintly.
I think this also occured initially when I put the car in "N" as it was edging to a stop. But I have not been doing this anymore. Broke it already?
