Tesla Model S Battery Drain Issue Fixed

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."

The 12V battery of a family member's Honda Civic didn't just draw more current than intended. It failed completely! The car could not start! The whole battery had to be replaced at cost to the owner and the Honda CEO was nowhere to be seen.

But expecting to turn all the electronics OFF in a present day automobile is not the smartest of ideas.

For sure the clock would be wrong - and just flash 12:00 all damn day :-)
