My car exhibits the exhaust buzzing problem.  It was in for a 30k
service at an independent garage (PR Motorsports), and they told me an
exhaust shield weld was cracked, and asked if it was buzzing.  They
seemed to know this problem, so it must be common.  Mine wasn't buzzing
then, but it sure does now.  It buzzes the most when accelerating in
2nd gear at higher RPMs.  It doesn't seem to be a function of
temperature or humidity (we don't have humidity in California), but a
function of the heaviness of my foot.

The other problem I had was that one of the rear brake caliper was
"frozen".  The floating part of the caliper was frozen solid, so that
only one brake pad was working (and getting worn down).  The dealer
"fixed" it under warranty, so that all the fluid drained out and the
brakes failed within a week.  They also conviently decided not to tell
me that the pad was worn down so far that it should be replaced.  They
finally replaced the brake assembly (under warranty), but took four
days, because they said there were no brake pads or calipers in
inventory.  No more business for that dealer.
