Has anyone noticed a single click or knock type sound in the front end when creeping at low speed around parking lots or pulling into garages? I hear it when a window is open and I've just taken my foot off the gas either in drive or reverse, but doesn't occur in neutral. Can't hear it when the window is up. Driving slowly by a wall or into a garage amplifies the sound due to reflection. My dealer service rep heard it when I brought it in and after he checked with a Subaru master tech who happened to be there that day I was told by the master tech that it's a normal sound created by a servo (I believe he said related to the CVT transmission). He said they all make that sound and sure enough, after my asking to hear another Ascent on the lot, that one produced the same sound. Just curious if anyone else has heard it too and whether the CVT servo answer I was given sounds correct.
