So first contact with Tesla Service came 2 years later when they told me there is a complimentary service to check some bolts tightness, as I had no issues with the car or issues with complimentary check, I let them do it. Now 2 months after that I had a squeak develop on the left front end near the wheel, I sent them the sound recording of it and they scheduled a check. They took one look at it and said they know its the left front control arm joint and will replace under warranty, they just had to order the part. Took them 6 weeks to get the part but they replaced it in less than an hour and the squeak was gone.
My car was identical to yours, same squeak in front upper control arm ball joint just started last week. Dropped the boots and water came out, so clearly they need to be sealed better....regreased and sealed, no more squeak. No other issues in 25K KM and 2.5 years.
