I'm sure the Model 3 having a single multifunction screen that does everything (combining entertainment with critical driving features) will go great.

Why did your choice of words include “anonymous coward”?
On Slashdot, "anonymous coward" was the default username for anyone posting without being logged in. The linked reddit post is from a user who claims to have worked for Tesla in the past, and is (presumably) not using their "real" reddit account to post it. I don't read it as an insult.

Gotcha. That makes sense. Slashdot was never my thing. Thanks for clarifying; I had read it as bafflingly unjustified aggression.

#63This issue is best explained on Rich Rebuilds' recent video here: https://youtube.com/watch?v=o-7b1waoj9Q&t=525 This has been a known issue for some time, and it's amazing Tesla hasn't fixed it yet. As explained in the video, the issue is simply the base linux OS has full syslog's still enabled, which over time burn own the eMMC chip used for storage.

"Replacing a tiny part" is trivializing the work necessary to do this, in my opinion. eMMC flash is typically a ball-grid array part and it's soldered down hard to the motherboard of the processor. Almost every mobile device has the same setup and it's tricky and expensive to rework this chip. You need to carefully desolder it off the board, reball the part with the correct masking stencil, then reapply it without to…
This is the right answer
Replace the board, then you can refurbish it in a specialized lab
Same reason why genius bars won't replace components, just boards

You are right but at the same time one does not expect a component of the dashboard to actually brick a car. I guess.
While counter-intuitive, I have actually encountered this issue with other cars as well, specifically a Ford f150 where an internal problem in the APIM module (accessory protocol interface module, essentially the dash touchscreen controller) essentially bricked the truck by spamming the canbus with erroneous signals. Remember that modern automobiles are rolling networks with multiple interconnected controllers, some…
bricked the truck by spamming the canbus with erroneous signals.
Wasn't preventing this one of the design goals/selling points of CAN?

Luckily Tesla isn't very space or money limited with this pretty ciritcal component. An SD card would make life easier for everyone, as the logs could be easily read out and the booting OS changed - yay for actually owning the device you paid for. But wait: That's not something Tesla wants.

They have been replacing the whole media unit including the screen (and charging customers $2k-5k for the priv) where they could replace the processor module board (which is "just" a add-in board inside the media unit) keeping the rest of the media unit and lowering costs.
Sure refurbish the processor module and replace the eMMC at a proper rework station but replacing the whole media unit esp when the failed part is on a removable board just seems like a huge waste to me esp when the customer is footing the bill.

It feels like they should just turn off syslog in production builds, release it in a firmware update and offer a recall for everyone affected by broken board.

Problems with an SD card is that it will wear out even faster than an eMMC due to lack of FTL, and also friction fit instead of soldered connections means the part is susceptible to wiggling out of the socket and also corrosion between the contactors. Not sure of the benefits of an SSD over an eMMC. Guessing the former will have a more sophisticated FTL and other things.
Multiple companies make high endurance SD cards for things like dash cams and automobiles. Take, for example, WD https://www.westerndigital.com/products/embedded-removable-f...

If this anonymous coward's characterization of Tesla is true and accurate, it's not surprising https://www.reddit.com/r/EnoughMuskSpam/comments/99sbwa/form...
The wording makes it sound like you're calling the parent comment an anonymous coward. I also suspect a lot of people didn't catch the Slashdot reference.
Maybe he was hit / smashed over the head with an OPEN SOURCE CD?
