I have had the Model S for about 3 months and have been plagued with strange noise from the front left wheel weld. After several attempts with the San Diego service center to solve the problem I think they have made progress. FYI I have 19 inch wheels with air suspension. The SC dynamated the car and seems to have reduced the noise, to acceptable levels. I have driven several 85s and 60s with 19 and 21, the noise level in all the cars are louder than my LS 460. Maybe Elon should work on the cabin sound levels. I love the car so don't get me wrong, I just want perfect. :smile:
