I have had several black screen issues. However, Tesla will NOT replace my chip for no charge. This is their reply...
An occasional touchscreen reboot is normal and not indicative of accumulated wear. In the future, if you see an alert on the touchscreen indicating that a memory storage device has degraded, please schedule an appointment.
my response is, define occasional. Just like they say you SC a lot. What is a lot? 20%, 50%, 80%?
yeah same here. It used to be that it reboots maybe once in 2-3 months...now its weekly. I get in the car and screen is black. Can stay like that for several minutes and it will reboot itself, sometimes twice. Or can go longer and I reboot it. May be ok from time to time, but not ok weekly, or when it's 110 outside, or your sunroof is open, or you follow the traffic rules and use blinker.
Sometimes, screen is completely unresponsive, or part of it is unresponsive and part is responsive.
Sometimes, only part of the screen updates, and not the whole screen (so one part will have eg. quick menu, and the other will have nav
Sometimes, screen has corruption.
Sent logs multiple times and was told no hardware failures, just reboot.
So how often do you reboot your phone? Me, about once a year. Why would i want to reboot my car once a week, it's 2020, not 1995. If it needs a reboot, it should do it when I'm not trying to go somewhere.
Also told me to turn off energy saving, which will help with responsiveness. They cleared cache (not sure what cache we are talking about), which is an action that can only be done by SC - why???? That means whenever computer gets unresponsive, I have to go there so they can clear the cache.
I do not believe this is all eMMC, but it's possible I guess depending on SW design. That said, as consumer, makes no diff to me where the issue is, just fix it, it's crippling the car.
