Tesla Model S Battery Drain Issue Fixed 239

cartechboy writes "Does the Tesla Model S suck down power even when the car is switched off? Recently, a tweet to Elon Musk with an article saying so sparked the Tesla CEO's attention. He tweeted that it wasn't right and that he'd look into the situation. Then a few hours later, he tweeted that the issue had to do with a bad 12-volt battery. Turns out Tesla had already called the owner of the affected car and sent a service tech to his house to replace that battery — and also install a newer build of the car's software. Now it appears the 'Vampire Draw' has been slain. The car went from using 4.5 kWh per day while turned off to a mere 1.1 kWh. So, it seems to be solved, but Tesla may either need to fix some software, or start sending a few new 12-volt batteries out to the folks still experiencing the issue."

    That's 45 watts continuously, it should be more like 10. Multiply the wasted energy times tens or hundreds of thousands of cars and all of sudden you're talking about the output of an energy plant wasted every day.

    The whole battery had to be replaced at cost to the owner and the Honda CEO was nowhere to be seen.

    This would be because people will buy a Honda regardless of whether the dealer or company or CEO is a prick or not, where Tesla is trying to get itself a foothold in the market and Elon feels personally responsible if there's a defective product because it reflects badly upon the company. A hundred million Hondas Thousands of Teslas.

    For 45W? That's a lot of watts for a 15mA receiver.

    My god, one person's battery failed completely? That's truly shocking! I've never heard of a battery failing before.

    That is clearly a worse problem than every single Tesla Model S ever made sucking down 4.5KWh per day, every day, for months on end while Tesla sit on their fingers and do nothing to fix a problem that can apparently be fixed within hours of a single Tweet to the CEO.

    And the fact that the "fixed" Tesla still sucks up enough power to drain the battery in any other car overnight, every night, for the rest of recorded time -- well, that's just the price of having a shiny car with no doorhandles or keys, right? Pretty trumps energy efficient and intelligently designed every time!

    In every piece concerning Tesla on slashdot, there are a few people making negative comments about Elon Musk. However, not once have I seen the complaints backed up with facts, examples, or otherwise, just negativity without any indication as to why.

    Could someone please explaint to me why there is this hate on Elon Musk, and what it is about?
