This may not be specific to 2G MDXes, since I have this on my 1G MDX as well as my ex's TL. I guess I have just gotten used to this, but someone pointed out recently who was in my car that when I accelerate at slow to moderate speeds, there is this rattling tin can noise. I actually did not notice it because every single Acura I have driven has had this. Once it was pointed out, now I notice it. My old Volvo never had this, my BMW does not have this, and my parents' and siblings' cars do not have this. A friend of mine has a 2005 TL and he has it too (at least that's what he told me). Anyone familiar with this noise? It is only during acceleration from 40-60KM or thereabouts. And it sounds exactly as described - a rattling tin can noise.
