I'm also curious of those of you with 2011's that seem noisy bought after the tsunami/subsequent nuclear issue in Japan? (wondering if part shortages might have changed how they were produced).
My car was built in June. I wish I could describe the problem, it is the engine and I guess it is most noticeable when I reduce acceleration (if that makes sense) It is that rough ticking noises that these engines tend to make it is just unusually loud in the cabin. I have no other F sport accessories other than what came standard on the F sport package.

I bought my 11 IS in August and I also hear a rattling sound when my engine is idling at 1K RPM, but the car is pretty quite on the road.

Not necessarily -- mine is pretty quiet unless you push it hard, and then it sounds a lot like any other V6, including the 3.5L in my last car (Maxima).

That was the first thing I noticed when i went for a test drive in the 2011s
I ask the sales rep about it and they claim Lexus did an engine "tuning" for the 2011s, which sounds like total BS to me.

Yep sounds like BS, my guess is (assuming no actual mechanical problem with my car) that they removed some of the soundproofing.
