I got my MX in March this year with the following configuration:
Model: P100D, Full Options
Wheel Base: 22'' Onyx Turbine Black
Date Build: Dec/2017
When I drive at high speed on freeway above 80 MPH my steering was shaking lightly and shaking increase at higher speed. I brought my MX to Tesla service center and address this issue with service supervisor. First time, the technician did wheel balancing and alignment but it did not help much and there is only slight improvement. Second time, they did balance the wheel and do some calibration but it did not help. I am not sure what the cause of the vibration at higher speed, it is very unconformable feeling. I brought my car to service center for 3rd time and they found nothing wrong, the technician recommend me to setup the suspension at standard height instead of low and change steering mode to sport when I drive on freeway. It was help just a little bit and steering still shaking at high speed over 80 MPH. When I setup the steering mode at standard it even worst and if it is at comfort mode the steering even shaking more violently. I did some research and MX owners with 20 inches wheel most likely don't have this issue since it is smaller tire and tire performance (bigger wheel) trade off for stability when drive at higher speed. I am not sure this vibration issue is common for 22 Onyx wheel or something else contribute to this issue?
BTW: I always turn off lane departure warning while driving.
Thanks
