A very interesting occurrence
About two weeks ago, my Model X, Pensive, started making an odd electronic sound. Tesla service responded:
Thank you for reaching out to Tesla Service, we appreciate your email. This is a very interesting occurrence, and one that we do not entirely know the cause of, as the vehicle logs do not reflect any information that might help shed some light on this.
They continued with general directions for resetting the MCU via the scroll-wheels.
