So, I've noticed this issue lately. When starting to decelerate, I can hear the sound of air escaping from somewhere under the car. It's the same sound that you would hear when the pneumatic doors of a bus opens. After I drive for 15 or 20 minutes, though, it seems to go away. I emailed Tesla Service - they said that it represents air from the suspension system used to recharge the dehumidifier, but it seems excessive, considering the number of times I hear the noise. There are absolutely no driving issues, and air suspension works fine. Anyone else experience this?
