Any other examples of the big 3 US, German, or Japanese car makers having a similar issue? Where a media center issue causes the car to not run and the manufacturer refuses to fix the issue or even provide a part for it?

The article is misleading. The manufacturer does fix this. They just don't fix the bad chip. The replace the card instead.

Thank you. What a willful ridiculous article from the author.

This 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. Currently Tesla just replaces the entire media unit when this happ…

Wow, this is exactly the tutorials that you get on "How to get your Rasberry Pi to run stable for extended periods of time". Exact same failure mode, exact same fix proposed.

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.

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.

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 article is misleading. The manufacturer does fix this. They just don't fix the bad chip. The replace the card instead.

Except they don't if the car is out of warranty, which (at least in Canada) is 4 years or 80,000 km.

I don't think this is just me but I believe cars should be able to last longer than 4 years and not get bricked by fault of the manufacturer and then not at least easily give me the ability to fix it myself if they won't.

Wait. Do they have a fix but the fix is replacing the board and not the bad chip?

Is Telsa not fixing things or did they just use something that had a short life span? Not sure why I read this article.

Model 3 owner here. Having same issue as back in March. No AP, no FSD and most frustratingly, no cruise control. Multiple TS steps over phone with no resolution. The earliest appointment was months out so I drove into a service center. A frazzled, yet personable, tech assured me that the issue was NOT from the recent FW update but rather a hardware malfunction with the left repeater. I pressed for details- is it wiring, hardware, physical damage? He couldn’t tell me, but insisted that it had nothing to do with the previous FW update and that another FW update wouldn’t resolve it

Tech scheduled a service appointment for 4-13, much better than I could find in the app. On 4-4 Tesla pushed a FW update, which I guess is pretty common before a service appointment. On 4-5, a Tesla rep reached out and said the issue WAS in fact, with the original FW update and that the more recent FW update had resolved:

“Hello Sam,

We have reviewed your vehicle logs and alerts. At this time we do not see any issues with the Autopilot system as well as you confirming that the system is operating as designed. Since this is the case there will be no need for you to come in for your scheduled appointment. While there is no way to say that you will never have an issue again, at this time there is no issue that needs correction. If you do have an issue in the future you are always welcome to create another appointment with your concerns.”

I responded:

“Ok- I’d still like to understand what happened. It is generally acceptable that the universe is getting more disorderly. It is perfectly acceptable that something goes wrong and we don’t know why. It’s significantly less understandable, that the issue mysteriously resolves it self. Does that make sense?”

Tesla Response:

“Hi Sam,

It was found to be a software bug in the last update that was performed causing your cruise control not to function. That was resolved in the last update you performed.”

The rep then canceled the 4-13 appointment without further explanation or communication.

The issue returned yesterday (5-13) and now the earliest appointment is mid June.

Cruise control existed in 1958. I get that Tesla has “tight integration” but the lack of a fall back/degraded performance mode seems ridiculous. This is before considering the lack of NoAP and FSD, which adds insult to injury- Those features represented nearly 15% of the vehicle cost in my case ($8,000 upfront).

Convenience in LA traffic was a primary consideration when purchasing the Tesla. The lack access to purchased features is irritating, but I knew they were bleeding edge. The further loss of a ubiquitous feature like cruise control is even more irritating. Tesla’s handling of the situation feels ridiculous.

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…

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 of which are required for the vehicle to function.

Note that this doesn't excuse Tesla here, since the situation I discussed is very rare, normally if that module fails the vehicle will still start and run. Tesla engineers should absolutely have been aware of this issue, as pointed out up thread there are multiple tutorials for ras-pi SD memory preservation, and I have trouble believing a competent EE shouldn't be aware of life issues due to eMMC. It also shouldn't brick the car, normally automotive electronics are designed very carefully to avoid single points if failure, with fallback routines and safety "limp-home" modes in case of problems.

Earlier quoted context omitted.

The article is misleading. The manufacturer does fix this. They just don't fix the bad chip. The replace the card instead.

Do they not replace it out of warranty or simply don't pay for it out of warranty? There is a huge difference between those two options. If it is the former, I would imagine it is just a matter of time before a lawsuit. If it is the latter, then isn't this functionally the same as a particular model of car having a bad transmission or similarly critical ICE component that regularly fails much earlier than expected?
