Searching for threads on interior noises is as hard as describing the noises themselves so forgive me if this has been handled before. Model S with several months under its belt, developed an interior noise that bothers the driver (me) the most. I think its coming from driver side of the car, interior, but I cannot even isolate it. When cruising at speed 60MPH 100km/h ish, hitting an expansion joint or crack running across the road brings the noise out. It takes a high speed slight jarring and is otherwise silent. Hitting same cracks at slower speeds does not bring it out. Sounds like short burst of crickets chirping, or coins rattling in a pile, or a light metal chain jangling.. No, it's not coins in my pocket. It's hits my left ear, not nearly as noticeable in the right ear. It's subtle but persistent... on long trips starts to drive me nuts. Others in the car have a hard time hearing it from their seats. It's really hard to isolate because of its high frequency, low volume, brief sound. I cannot determine if it's in the door, in the B pillar, in the seat, or in the dash. If I move my head around that whole area of driver's door the sound is about equally loud. Applying hand pressure to surfaces of things (door panel, seat sides, dash components, etc) does not cancel or diminish it. Shifting my body in seat, changing seat settings, no effect. Different steer wheel position settings, no effect. I've had the creaky seatbelt fix done with friction tape at the belt exit slot in the B pillar. That was nice. This crickets noise existed before and after that fix. IDEAS?
