Recreational Vehicle Lpg Tank Valve/gauge problems of the 2014 Tesla Model S

There is a known issue with Tesla media control unit (mcu) dead or won't turn on due to poor design of the emmc memories. The unit eventually dies once the memories are full and the unit won't turn on anymore. Since this mcu is the heart of the Tesla vehicle, all the safety features will be disable like collision sensors, hazard alert/notification, unlock the door/windows from the inside, most of the gauges on the dashboard are disable, even the lane turn signals are disable and the backup camera. My unit went out since may 2020, Tesla will not cover the defected unit, it they will charge me over $1700 to replaced a refurbished one. This is the 3rd time they reschedule my repair since they claim they don't have all the parts in stock. I've been driving the car with a dead mcu for almost 3 months. It is very unsafe when I drive the disable car on the road.
