Hi There, I started a post on Tesla' Forum on March 8th about the same issue posted by
ptekngo above. I noticed he saw my post there too. So, connecting the 2 forums, I can report that i have been waiting patiently through the 3 month waiting period. Tesla San Fran had agreed to fix the problem in that period or buy me out of the lease for a replacement car. I have been communicating diligently over this 3 month period with the service manager. The clock runs out next week.
In the past few weeks Tesla brought out a noise and vibration Engineer to review another car in SF with a similar issue. They, to date, do not have a fix with the strut manufacturer. 2 weeks ago they manufactured a strut support bracket that attaches to the frame at 2 points with resilient rubber mounts to isolate the offending vibrating parts from telegraphing noise into the front chassis. This a "not a fix" according to the assist service manager but a fix for the symptom. Tesla has manufactured the part and it has a part number available for others to do the same fix. I'll attempt to provide that number for you. I should have taken a photo of it for this post.
The other customer had the fix done last week. The Tesla Engineer and owner appear to be satisfied so far which prompted them to make a second set for my car. we are on the bleeding edge here.
My car is in Tesla SF's shop today to be fitted with the brackets. Its a one day install. I will come back to the forum in few days with an update for you all. Stay tuned.
