Love how quiet the engine is for the most part...UNLESS the A/C is running. Does everyone else notice how loud the compressor and/or belts are when accelerating, or idling, with the A/C on? I've owned 10+ vehicles and have never heard so much engine-related noise when the A/C is on.

On a different note (with or without the A/C on) - I've noticed a whistling noise when accelerating. It almost sounds like a turbo. I remember someone mentioning that it was a hose with a slight hole in it that the dealership fixed but would love to get rid of it. I'll take the whistle in a turbo diesel, but I dont want to hear it on a gas engine.

Thoughts?
