Official summary
Some Autopilot HW2 or later Model S and Model X vehicles with Tegra Media Control Units (MCUs) may emit a faint static noise coming from the tweeters on the A-pillar. The noise is generally heard when it is very quiet in the cabin (the vehicle is in Park with climate control and media player off, etc.).
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
