They have turned the car upside down and listened to it from all angles. They put sound sensors under the hood to record the noise during test drives. The air leak hypothesis makes no sense to me since the whistling noise stops as soon as you take your foot off the accelerator and begins again as soon as you hit the gas. Speed and wind angle are constant. I'm losing confidence that they can fix it.
