    Well given basically everything goes through the MCU it has to have many points of failure.
    Good thing is that replacement MCUs are rock solid so far

    Thats a very clickbaity headline.

    The 12v died because the car was sitting up. Hardly newsworthy.

    12v battery

    that's a serious design flaw. Bad enough that the 12V battery goes flat but to make you partly dismantle the car to trickle charge it is ridiculous.

    Silly title of a vid, loses credibility with that one.
    I can't see his Tesla's front end but with mine (nose cone) there are two jumper connections right at the front of the car that take 10seconds to access should you want to trickle charge or indeed jump the 12v

    Most people use their car regularly, James has several cars and obviously left the Tesla unused for a long time. It's a non-story.

    James says in the video that he leaves the car connected to the charger permanently, when not it use. I thought that was bad for the batteries?

    Happened to me a couple of days ago. It was beyond reviving, so I took the battery out and the kind folks in Halfords replaced it free of charge as it was within the 3 year warranty period

    That was in my Porsche BTW...


    As you say this will happen in any car that has been sitting up. In fact it is far less likely to happen in a Tesla than in any other car, as Teslas are always awake and regularly check the voltage of the 12V lead acid battery and top up where required. But once a lead acid goes past a certain status, it is very hard to bring it back to useful life. Thankfully within the next decade or so, lead acids in cars will be a thing of the past

    so he left it connected while not in use and the 12V battery still died. that is a design flaw.

    Every car with a 12v battery has the same design flaw...

    clearly? he was trickle charging it so it hasn't failed.

    What’s the relevance?
    A dead 12v effects an EV just the same as an ICE.

    In fairness to the owners, it’s very simple to do. James overly exaggerated it for a YT clip which is fair enough as he wants it to be entertaining and click bait and attract viewers.

    Here’s the simple process in opening it :

    It takes 10 seconds!

    That's the surprise. a car full of electricity can't keep a tiny battery charged.

    In the same way a car full of petrol can’t keep a tiny battery charged.

    the ICE car isn't sitting there constantly monitoring itself. the EV is. if it detects the 12V battery is low why can't it charge it?

    it doesn't. EV is supposed to be an improvement on ICE

    It's a legitimate question. An ICE car does not have a source of power to charge the 12v.

    In some things yes. In others no.
    12v batteries have been going dead in every EV out there. They are under more strain than in an ICE so it’s to be expected if not maintained as it’s a consumable item.

    I thought the argument was that it was so hard to charge the battery in one of those Tesla’s but since that’s been proved a fake we have moved on.

    but another poster claimed that the EV battery did charge the 12V battery so why would leaving the car sitting there drain the 12V?

    if you have to remove trim panels to get to the battery terminals then I would class that as hard to charge. Nothing has been proven fake.

    Have to remove plastic panels in many many cars to access the terminals to charge many many cars. Have to remove half the boot in my 520d to change the battery.

    and you don't consider that a design flaw?
