There have been incidents that the MCU does not power on, like for 5 mins and still a no-power blackscreen, sound lost (streaming, radio, signaling), and sudden signal drop (4 bars to suddenly no connectivity at the same spot) and would require a soft reset (holding both scroll wheels) to resolve. May be not affecting driving but I cannot access the MCU to open the garage too :(. I scheduled for an appointment for that MCU emmc check and replacement but the appointment got cancelled without my confirmation. Tesla service left a message saying they have done a remote analysis, 2 weeks after the previous incident, and claimed it was working at that time (of coz it would, else I won't be able to open my garage for a while) and said they have therefore cancelled my appointment.
I would like to confirm if these signs/incidents more due to the emmc chip failure on the MCU? My model X is the Oct 2017 model. I have book another appointment again about this issue since MCU just failed to start again few days ago and hoping they don't cancel again.
