I've had my car for almost two weeks now. It's fantastic. However, its very hard to know which sounds are normal and which sounds might need a trip to the service center. For example, when I first "wake the car up" in the morning I hear an audible loud-ish click from under the car -- it sounds like a relay closing. (i have V 5.0 of the software). Perhaps we can create a wiki page here that has recording of these sounds so we can compare the "good" from the "bad". Other fun sounds are the air-suspension, the air conditioner, the sound of the car under VERY hard acceleration -- I had my first "My Tesla Saved my A$$" today when I had to accelerate very very hard and fast when someone tried to occupy the same space as my car -- the sound of the juice flowing at that rate is fun.
