Am I the only one thinking about the recycling and cost implications of doing this?

This is rather disingenuous. Of course Tesla doesn't replace the eMMC; that's a soldered on chip. No car manufacturer in the world does chip level electronics repairs. Instead you replace the entire board, and I have no doubt you can get this repair from Tesla. That's not to entirely excuse Tesla. If you have a modern operating system running from flash that needs to work for 20+ years as people expect from a car, it…

According to the video, the log is not used for anything and is basically unnecessary for the most part.

Why a full memory chip logging data which is never used should brick a car is simply price gouging.

There is no need for it whatsoever.

Thousands of dollars to replace a board because of a full memory chip? That is even worse than Apples repair racket, at least in Apple's case some other circuitry besides memory is faulty - https://www.youtube.com/watch?v=2yJKix17yYE

I'm not sure you understand the situation.

This is the board the chip is on, which Tesla does not offer to replace: https://share.icloud.com/photos/0u78AylGb9fv8QHQnyr9IC3nA

This is what Tesla will offer to replace: https://share.icloud.com/photos/0MVG8edJheaHYiEp7yWKkVePg

Is that what you were imagining?

The orphan car problem is a serious issue with non-Teslas, too, but I will personally stick to repairable vehicles. You know what you'll never, ever have trouble finding parts for? A Mustang or an F150. Corvettes. Carollas. All of the ubiquitous cars will have parts produced for a seriously long time.

The corner auto parts shop stocked almost every part I needed to work on a 1982 F-150.

Do you know that they toss the old media units? Are you sure they don't swap the entire media unit to simplify service procedures, and have have the old units inspected and refurbished (i.e. eMMC module replaced) for future repairs?

That sounds way more efficient than training all of the shop workers to diagnose and swap out individual parts of the media unit.

Tesla screwed up by using eMMC memory (flash memory with an integrated controller) and not disabling system logging. The additional writes cause the flash memory to wear rapidly, which should have been mitigated as this is not a new issue in embedded devices. As the chip is soldered and not socketed, the solution is to swap the entire (expensive) board, and Tesla won't do this for out-of-warranty vehicles and hasn't…

Tesla won’t do this for free for out-of-warranty vehicles. Replacement cost of the entire board is unfortunately high at around $2,700. [1] - https://teslamotorsclub.com/tmc/threads/2700-to-fix-mcu-migh...

From your link:

>I think we are on drivetrain #5 and it is now that one clunking intermittently, so maybe we take that one back in. We are on battery charger #2 and battery rebuild #3. We had most of the upgrades (wind noise on the door windows, etc). We had a left rear door handle start to go bad, took it to the shop and they fiddled with it and wanted to replace it, but afterwards no problems so we did not replace it.

Drivetrain #5, charger #2, and battery #3. All under 125k miles. Wow I’m not so sure I’ll be buying a Tesla for my wife.

As is so often the case with articles about Tesla the headline is completely misleading. No cars are getting bricked. Tesla fixes that problem by replacing the bad board but they won't replace the bad chip on the board and they won't sell the chip separately. Other manufacturers don't generally do that either.

> they won't replace the bad chip on the board

There is no bad chip on the board.

A full chip is not a bad chip, and there is no reason why the board should stop working on account of a full memory chip which contains a syslog that is not used for anything.

Hacker News is riddled with shills and apologists for atrocious corporate behaviour.

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.
