Two problems related to owners/service manual have been reported for the 2016 Tesla Model X. The most recently reported issues are listed below.
The mcu (main graphical display) will lose all sound (loss of warning sounds, blinker sounds, loss of radio), freeze (requiring a manual reset/reboot, or take a long time to boot before the car will start. This happens frequently (many times a month for the last 6-9 months). It has been somewhat less often after a recent software up from Tesla. One should not have to reboot their main display to return functionality while driving (driver distraction potential).
Sudden unexpected failure of mcu1-the main control touch screen of the car. Limiting access to key safety features such as back up camera and other vehicle controls. The vehicle had an unusual display behavior and took a prolonged time to wake up, then the center display failed to turn on at all. Manual reset attempts failed.
