You may be experiencing new-owner-syndrome. I know I had it for my first 2 or 3 months - all kinds of odd little noises that I hadn't noticed in other cars (but I assume totally benign - like the noise when the auto-temp releases some Freon behind the dash or whatever it is doing). There would be expected to be some particular harmonics in exhaust and gear noises that vary with rpm, or only show up at certain places. Rest assured that these cars are smart enough that they'll throw a code if anything is starting to look seriously out of spec.
