I thought I'd pass on my experience with my 08 RDX. Right after I purchased it I felt that the turbo was noisier than the other RDX's I had driven. I brought it in to be checked right after I purchased it and they told me everything was fine. So I went the last 2 months thinking I'd have to live with it and wasn't too happy as I knew the other RDX's I drove weren't nearly this noisy. Well, I took it in again this past Friday and told them there HAD to be something wrong. This time I believe they decided to look a bit closer and apparently an intake breather hose wasn't connected to the turbo. The dealer says that they must not have connected it at the factory. Now that this is fixed its like driving a different car...the turbo is MUCH quieter...its still noticable, but barely...its a huge difference.

Anyway, just wanted to pass that info on in case other people seem to have an unusually loud turbo.
