Any idea if the end links on the front sway bar were replaced in your repair? A friend of mine had a creaking noise coming from the front of the car a few years ago. I helped him replace them and that ended up being the cause of HIS noise. They were relatively cheap IIRC and they were pretty easy to swap out. But.....I'm not a mechanic, and if the 2 of us could compress the front suspension and ascertain that the noise was coming from the sway bar end links I'd HOPE a certified Tesla tech would have caught it on your car before throwing parts at it!!
