Tesla Covering Some MCU1 Issues for Some Owners

Still Trying to Figure This All Out
Update: Since I went to MCU2 (about 2-3 weeks ago, paid out of my pocket), 100% of all the issues I reported/that occurred after getting the HW3 installed/with MCU1 in place, are now 100% gone. That includes summon/smart summon now connecting literally 100% of the times I've attempted to use it. Including when my car and/or my phone, are on home wifi. My streaming services are almost flawless now. No waiting, no loading errors/no timeout errors. Navigation is fast/quick/no delays. Voice commands are recognized almost 99% of the time. And this is with a USB connected/dashcam running/sentry enabled.

@2101Guy, I don't know how I feel about this. I'm happy for you, but sad as well. I feel like the right thing for Tesla to do would be to discount the MCU2 for FSD HW3 owners since they literally broke the car. Maybe meet in the middle (i.e. $1,250)?
Glad you're happy! Also, am glad to know that upgrading does indeed fix all the issues!

Per the title of this thread, here is the new Tesla instructions TSB filed with the NTSB, for evaluating the eMMC:
Link posted earlier did not take. Working on it.

They said that those details would be released in February, 2021. It isn't February yet, so no details have been released.

Update: The service center (bot?) texted me today to say the part had arrived, and I should schedule a new appointment. I took the earliest one at that service center which was January 18th. (I originally initiated a service appointment on 11/26.)
Fingers crossed. I got the "storage device degraded" warning, and my MCU previously required service for blank screen (which was address without replacing any hardware). Yesterday, my car started acting up. The MCU appeared to be working, but turn signals made no sound and Slacker streaming wasn't working. I rebooted the MCU and it took something like five minutes to come back up, but it did start working again.

Suggest bring a copy of the TSB. It indicates that display of the warning is grounds for replacement of the chip.
Good luck and let us know how it went!
Is that MCU_w088_eMMCNeedsReplacement or MCU_w086_eMMCEOL? Any way to tell which alert my car is throwing?
I'll be sure to post an update after my service appointment. Thanks!
You should be able to go to Menu>Service>Notifications to see a list of prior alerts, and I think that shows the alert code as well as the description.
There's nothing listed there. I just have the "center display storage device degraded" message on the instrument cluster.

They are not making it easy for us...get a pic of the message, submit it in the service request app...
When I first scheduled the service, it actually pulled the message from my car, as I recall. That didn't happen when I scheduled this time around. But hopefully that info is still tied to my service appointment, given they ordered the part for me. (I'm wondering if they ran through the steps in that TSB remotely before ordering the part.) I do have a photo of the message from back then, and the message is still appearing on my IC.

Don't let them pull a fast one by clearing you home folder or some other such nonsense. Point out they should be following the Tesla approved procedure in the SB, i.e., replacement, when an alert is observed.
