I knew this was an issue but was surprised that the MCU failed so soon. I have a 2015 90D that I bought from Tesla in 2018 so it is still under warranty. 36,400 miles. I had a few issues in January/February where the center screen spontaneously turned off for 1-2 minutes while driving. I also had a jumbled display when pulling up the HVAC once. I haven't driven a lot since then but I did notice that for about two weeks before the MCU died, a new software update (2020.12.5) would not install. It would go to 10% and stop. I didn't think too much about it.
Here is what happened when the MCU died for good. Car was technically driveable but:
-Center screen was completely off (screen above steering wheel still on)
-Odometer showed ----
-Temperature showed --
-Parking sensors did not work
-Turn signals did not work (but emergency blinkers still worked)
-Phone app not connecting
-Soft and hard reboot attempts had no effect
I brought the car in this week and they put in a remanufactured unit (part number 1098010-00-G). I did speak to someone in the service department and asked if this one they are putting in is going to fail again because of the memory defect and he said it's been "corrected" (via a software fix). Can anyone confirm this (that the logging issue that eventually causes the eMMC memory failure been fixed/improved)? Or is this going to crap out again in 4 years? Does anyone know if they start with a new eMMC memory chip on the remanufactured units?
