My drive unit was replaced due to inverter noise only (they called it "milling noise," but it was a low volume high pitched whine. The pitch increased with acceleration, but it was only audible at very low speeds, when 5-10 kW was being drawn from the battery, no more. Recently the inverter noise has returned, but at a lower volume than before. Tesla Service measured with volume and stated that it was too low to warrant another replacement at this time (I agree), but they will keep an eye on it, and may still replace the unit if the noise gets worse. My own theory is that giving "demos" of the Model S acceleration (by flooring it) leads directly to this issue. The inverter noise seemed to appear right after giving such a demo, which is really unecessary. I'm not giving any more "floor it" demos.
