RDL0100

A new experience today. After I come to a stop, the steering wheel is perfectly steady and silent. After a couple of seconds, I can literally feel something cycling on through the steering wheel. It is very obvious. I turned off air conditioning, but it still does it. Pull to a stop, wheel is steady and quiet, then suddenly something cycles on and the wheel starts vibrating. Cannot feel it through the seat or anywhere other than the wheel. Can't hear anything particularly when the hood is open, car is running and wheel is vibrating. Anybody have any suggestions as to what it might be? It was in the shop last week and pronounced fine (it wasn't doing this then) and is scheduled to go back in next week. I'm sure they will tell me its being doing this all along, and I would like to have some thoughts about what it could be so I could discuss it with them. Thanks for any help.

Dealer replaced motor and transmission mounts plus the pulsation dampener, all under warranty. Vibration is now gone.

I had the same symptoms on a CL550. New motor mounts fixed the vibration that was there only at idle and low speeds.
