I discovered my car had a suspension noise today. If you sit in the car and rock the car left and right with the doors closed, you can hear a slight knock or pop. Took it in to the dealer and they lifted the car and found the problem, but couldn't fix it.
Official TSB PI0645: Knock or pop noise heard when coming to a stop or at low speeds over small bumps - Jan 10, 2012.

Some customers may comment on a knock noise or pop noise heard from the front strut assembly when coming to a stop or low speeds over small bumps in the road.
Engineering is aware of the concern and is working on a new part that will correct the noise concern. Please DO NOT replace struts for this concern as a new strut will be available shortly.
My dealer did not have an ETA as to when this strut would be available and suggested that I call back in a month to check for availability and to schedule an appointment. In the meantime, I'm stuck driving a broken car until GM gets a part ready. 22 days have passed since the release of the TSB and their "available shortly" strut is not yet available.
