Since you are in Hawaii you have limited choices on Tesla Service Centers. I would document everything in a letter, attach pictures and be nice to the SC manager. Explain that the service tech(s) said this was normal but that's not acceptable to you. If you hit a wall there, ask to escalate to the regional manager and go up the chain from there. Your state may have specific laws around new car warranty claims too.
I think it's unacceptable for three month old car to have this. Documenting everything, being persistant and nice will help getting this resolved.
