    I would expect a few more of these types of issues to emerge moving forward, trouble is on a Tesla this could effectively write the car off as everything is controlled from the centre screen.

    Some of these cars are only 3 years old - what happens to vehicles like this when they are 5+ years old and the processors are no longer available - you can't easily swap it for a different one....

    Scrap yards could be full of them

    The chip stores data on every use of the car and eventually fills up?? That is shocking.

    They should ask new Tesla owners . . . "Would you like chips with that"? :ROFLMAO:

    From what I can gather, it's not that the memory fills up, but rather that the memory eventually fails. This is because flash memory can only be written to a finite number of times, similar to the fact that a battery can only be charged a finite number of times.
    There are strategies which can be implemented in either hardware or software to minimise this effect, but it can't be eliminated entirely.

    That is 100% correct, flash memory just wears out. I have no knowledge of Teslas obviously, but my job of 25yrs until recently was telephone system maintainer for a large national company.

    One of the largest pabx manufacturers in the world insisted in using cf, and later on, sd cards for storing the fixed prompts and operating system etc of their voicemails and auto-attendants.

    Their imminent demise was indicated by the speech starting to jitter and then disappearing altogether. Of course the manufacturer would not supply just the media card by itself........... but this isn't a telecom forum so I'll spare you the details.

    I work in IT and have worked in automotive, it's amazing how little the engineers that apply technology know about IT and especially security, in my experience they are mostly arrogant too and think they know best, most of the coding is shockingly bad and full of back doors that can be exploited.

    What gets me is that any process is not down to ONE person
    It has to go through concept, design, manufacture and you hope testing, (probably involving loads of bods in meetings)
    so it has to get through several "thick" heads - amazing

    Well as I said earlier, I don't believe that this issue is caused by the memory "filling up", whatever that means. It's because the flash memory has a limited lifetime and simply wears out. Just like batteries, tyres, shock absorbers and many other components do. Are they all badly designed by idiots?

    The trouble here is when journalists, who don't really understand the technical issues, report incorrect nonsense. It happens all the time even on major news websites such as the BBC.

    For what it's worth, I work in the automotive IT industry, albeit on the GPU/graphics side, so I do know a bit about the subject. And yes these systems do go through an enormous amount of testing. However the GPU driver I am working on at the moment contains just over 1.5 million lines of C code, and that's not the whole system on a car, just the graphics driver part. There will inevitably be bugs in there, such as resource leaks and other nasties, which can be notoriously difficult to find.

    We license our products to companies who integrate that into their product that they sell to other companies who in turn sell to car manufacturers, so there is scope for bad communications and things to go wrong there I guess. So not only is it not down to one person, but it's not even down to one company.

    Wow, just read the BBC piece. I have reservations about electric cars and also their green credentials i.e. lifetime or embodied carbon which is even worse if they die prematurely.

    ICE cars are over reliant on microprocessors so the idea of a car that dies completely is nuts.

    it says in that articlec that

    l would say that 10 years is probably close to end of life for a tesla anyway. the battery has an 8 years or 100,000 miles warranty, whichever comes first

    so a model three that cost near fifty grand new would be worth around eight to ten grand at eight years old being generous (Sunday morning fag packet maths)

    so at ten years the battery gives up the ghost and needs replacing. and tesla will charge fifteen to eighteen grand to fit a new battery to what could be a five grand car at that stage of its life. and as the tesla parts market is still pretty much only in house at present that is just not going to happen so a ten year old car will be scrap

    To repeat an old post, what will the less well off drive in the future?

    The switch to all electric seems ill thought out to me.

    very much so. there will be no such thing as a cheap car in the all electric future

    just look at how many sub two grand cars there are on the roads of the uk. so a two grand car needs a new battery and you can fit one for a grand you may do it but once the battery costs more than the car is worth the car will be scrap

    l am off to the workshop to work out how to fit a BMW N47 diesel motor into a tesla model three. it will be like Cuba with all the big block Chevy motors swapped out for lada four pots

    Call me wrong here....
    And I am definitely no electric car fan ... believe you me....but it would seem we are going to have no choice...
    Tesla’s are holding their second hand values very well... my colleague has just been given exactly what he bought his model S for 3 years later to trade into a new one... it was ‘used’ to him when he got it..
    If there are much less things to go wrong...?( so we are told)
    Won’t a battery change ... just give the car a new lease of life... short of suspension and brakes admittedly..
    I think the electric car has a fairly long life span..batteries will get cheaper....what’s the life span of the motors..? And now corrosion is barely and issue to modern cars..
    I reckon at the 8-10 year mark.... and new set of batts, a software complete wipe and reload...won’t these things be ready to start their next 10 year life cycle...? Or have I got it completely wrong..?
    As an aside I have just watched Matt watsons review of the new MB EQS...
    I want one.... apart from dog to move and caravan to tow...! 500 mile range now.... surely despite most of us hating these things, we have to accept they are getting there.....
    Look at the tech change in mobile phones over 10 years.... and we are not now far off 2030....

    You may well be right, but to “refurbish” an electric car will be expensive and out of the price range of many.

    One of my neighbours has a P reg Astra that must be worth all of £300, but he isn’t interested in cars and only works a mile away, so it works for him. Extremely cheap motoring.

    i have seen some of that rich rebuilds Tesla LS swap but he hasn't got it running yet and it now seems to be on the back burner for a while. he will get it running eventually but we may have to wait a while before we see it

    i am by no means an electric car hater and i would actually buy one if the range and charge infrastructure was in place to make it a viable option just maybe not a Tesla

    there was a case in the US where a model three owner had to replace the battery pack due to damage not covered by warranty and the cost was $24,000 on a car that could have a new price of $37,990 so at what point does that become a non viable repair

    also at the bottom end of the market you can buy 2011 Nissan leaf with 77000 miles on it for under four grand and on a full charge it has a 70 mile range which is fine for a city shopping car that does no more than a handful of miles. you could have a new battery ftted to that car by Nissan for £4,920 and you will get £1,000 cashback for the old battery. now is that a viable repair on a sub four grand car
