A few weeks after I took delivery of my S85 with coils and 19" wheels I started hearing a rather noticeable noise when I make my first turn or go over a speed bump. This only happens after a "key cycle" and it sounds like a low pitched "eek". I've had Tesla service take a look several times and they just give me a shrug and say it's wierd but they can't figure it out. Has anyone else had this issue? I can't believe I'm the only one but if I am I would like to get it fixed cause I have this feeling like its a precursor to a problem. Thoughts?
