with the radio off, I can hear the A/C fan in faintly. I could never hear this before, but this is the first summer with the car. I know people have said that it is loud, but should it really be this loud? Multiple people standing outside my car when it is on have asked me why the car is so loud.

Yes, the auxiliary fan is that loud. Whether it should be that loud is another question, but that's the way it is for everyone. Somebody who lives in Florida compared it to the sound of an airboat - one of those boats with an airplane motor and propeller. Look on the bright side - it shows how effective the W211 soundproofing is. While people outside your car are wincing and covering their ears, you can barely hear the fan if your windows are up.

If you've got the SBC brakes, it will make whirring noises after you release the brakes. It doesn't happen all the time, but it does happen. You only notice it when the radio is off and you're in a quiet area. The sounds are normal operation of the brakes.

Yes, especially when reverse first thing in the morning, it is very loud and seems like something is definately wrong (sounds like something loose or something...), its definately not the brakes or AC fan in my case, as others mention...too lazy to take to dealer though
if you DO take it in, please let us know the diagnonsis ...thank you

I hear a metallic sound coming from below in these two situtions. Going at 5mph I need to sightly depress de gas pedal to hear that sound, (at full throttle only the engine can be heard).
Maybe it is not the same as you described.

Didn´t take the car for diagnostic yet .
