&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;youtube.com&amp;#x2F;watch?v=o-7b1waoj9Q&amp;amp;t=525&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;youtube.com&amp;#x2F;watch?v=o-7b1waoj9Q&amp;amp;t=525&lt;/a&gt;&lt;p&gt;This has been a known issue for some time, and it&amp;#x27;s amazing Tesla hasn&amp;#x27;t fixed it yet. As explained in the video, the issue is simply the base linux OS has full syslog&amp;#x27;s still enabled, which over time burn own the eMMC chip used for storage. Currently Tesla just replaces the entire media unit when this happens, which is extremely expensive for them. In reality they only need to replace a tiny part instead of tossing entire boards.&lt;p&gt;The GOOD news is this issue is almost fully solvable through a software update. They just need to disable base syslogs, or at least only store logs in RAM while car is running (if they need those logs for debugging purposes, which I doubt). Long term, they should replace this eMMC with a proper SSD, or removable SD card that&amp;#x27;s easily serviced when it goes bad (as is the case in other parts of the car).&lt;p&gt;I think this must be an issue of visibility in the company, and the right engineer just isn&amp;#x27;t aware of this issue yet. I hope this gets more visibility and gets patched in a future software update.</text></item></parent_chain><comment><author>joezydeco</author><text>&amp;quot;Replacing a tiny part&amp;quot; is trivializing the work necessary to do this, in my opinion.&lt;p&gt;eMMC flash is typically a ball-grid array part and it&amp;#x27;s soldered down hard to the motherboard of the processor.  Almost every mobile device has the same setup and it&amp;#x27;s tricky and expensive to rework this chip.&lt;p&gt;You need to carefully desolder it off the board, reball the part with the correct masking stencil, then reapply it without torching the rest of the board, missing a solder connection, or zapping any other component with static electricity.&lt;p&gt;You can see a similar process done on an iPhone here: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=y4M9uAZlbK4&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=y4M9uAZlbK4&lt;/a&gt;&lt;p&gt;You can understand why Tesla would rather replace&amp;#x2F;refurbish the board than try to field-repair it.</text></comment>

In reality they only need to replace a tiny part instead of tossing entire boards.&lt;p&gt;Do you know that they toss the old media units? Are you sure they don&amp;#x27;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?&lt;p&gt;That sounds way more efficient than training all of the shop workers to diagnose and swap out individual parts of the media unit.</text></comment>
