No idea how long I've had this but my VIN 4XXX S has a symptom I thought I'd better check on. Service is no help when describing it and not interested in driving 300 mile RT to have them look at it and scratch their heads again like they do with other symptoms. Basically when I go from stop to 5 mph I often, but not always a "nasty click" ... outside the drivers window, as if it maybe coming from underside of the car. Then decelerating from 5 to 0, it does it again about half the time. I thing back to when I hear other Model S driving around the SC's and cannot recall hearing it. Is it just me?
