I just want to stop by and provide an update on my suspension rattling issue, if this information is helpful to anyone. Two years ago, I went to Tesla Service Center and notified them of the clunking, bobbling, and rattling arising from the front suspension going roughly 15-30 mph. Service center then installed an updated air spring module (1067361-77-C), which worked for a few weeks, and then the noise returned. I lived with it for quite some time. But recently, I went back to Tesla and requested service again. This time, service center acknowledged the issue, stating the noise is a normal for that model S, but to help reduce this noise, they installed updated Shock Tower Braces. As of right now, after a few weeks of driving, noise is still virtually gone. Fingers crossed this is more or less a permanent solution.
