general problems of the 2013 Tesla Model S

This issue appears to be related to a known mcu failure affecting early Tesla Model S vehicles. The touchscreen exhibits screen melting/discoloration and eventually goes blank or becomes inoperative. When this occurs, critical functions including occupant detection indicators, seatbelt warnings, and windshield defrost controls may become unavailable. The loss of these functions creates potential safety risks involving visibility, occupant protection, and driver awareness while operating the vehicle. ".

The media control unit (mcu) in my 2013 Tesla Model S stopped working when I rebooted the car while stationary (commonly needed to restore lost functionality), apparently due to a failure of the embedded multi-media card (emmc) memory. As part of this failure, the turn signals did not work when I later went to drive the car, the passenger airbag defaulted to 'off' (pic attached), and the hvac system (including the windshield defroster) defaulted to an unknown setting and could not be controlled (neither by the dead mcu nor the smartphone application), though the car was otherwise still driveable. Apparently, the oem emmc had limited re-write capability and a relatively high re-write frequency; when it failed, it not only created driving safety hazards, but also cost more than $1,000 to repair what was probably an inexpensive part (under $10) for the oem.
