Here is an update (and I'm not sure what to make of this). I went out to the car a few minutes ago just to try again, and this time everything came up normally with no errors. I went back inside the house, waited about 10 minutes and then tried again.
Everything worked fine so I got brave and took a 10 minute drive around my area. I waited about 10 minutes and then repeated the test again. Everything still worked so I took another drive with no issues. I can't imagine how this would just fix itself. Maybe I had a different issue?

So, when this happens, do you have to pay the $100 for a Ranger visit? I live about 4 miles from a Service Center and so wasn't going to opt for the all-inclusive (i.e. Ranger visits) maintenance plan. If I can't get the car started in my garage,or worse 40 miles further away at work, this could be a problem.
In the US at least, some insurance plans will have a towing option that takes you to the nearest service center. Since you are so close, that might work. I would hope with a large majority of problems you can still drive the car. The ranger service still is nice but you probably don't need it.

To answer your question strider, my car was delivered on the truck with 4.0, with 4.1 waiting for me when it arrived. I installed 4.1 that night. After almost a week of driving and 500 miles, I've had no issues.
I wondered the same thing. I'll be about the same distance from my service center when it opens next month so I didn't get the unlimited either.
There have been several different issues affecting the 12v battery for folks (I got the scoop today on my factory tour). I can pick out at least 3 we've seen here -- 1) Bad battery to begin with 2) Bad hardware and 3) bad battery management (software/firmware) ... The number of different issues increases the number of 12v failures overall, and given the severity of a 12v failure, we hear about it more by nature. It's quite a bad twist of luck for the number of distinct problems in this area (especially in this area).
I'll admit my confidence was starting to sway given various recent reports, especially in this area; but now that I understand it more deeply (and can see how much more deeply Tesla understands it and is aware of it), I'm standing on firmer ground.
For what that's worth ...

I know the lawyering of language and such makes it more difficult, but I wish Tesla would come out with this kind of information on their blog. Reserving blog posts for large damage control and big announcements is a bit narrow-minded and "droughty" for my taste.

12V battery and charging problem
Hello
I'm getting a "12V battery needs service/replace 12V battery soon" message. I rebooted the dash and restarted the car but still getting it.
This is very strange, I received the car less than two weeks ago, the 12V battery is supposed to work just fine.
Also, I can only charge the car to 385 KM. It stops charging at 385KM and gives me a "charging complete" message. I'm using 110V 12A for charging.
Can anyone help me?
Thanks!

When I left my office last Thursday afternoon my Model S had cold-soaked all day outside at 46°F. After about 5 minutes of driving an alert came on stating "Battery is heating" and energy use leapt to the top of the display while projected range plummeted to 70 miles, down in heartbeat from 210 a few seconds before.
I took this to mean that the car had switched on a powerful heater within the battery system to warm it quickly to optimum temperature. (It did occur to me at the moment that this ambiguous message might mean the battery was over-heating, i.e., thermal runaway in some of the cells; but I considered this unlikely because of the liquid cooling). After another 5 minutes the warning disappeared and all seemed normal.
The next morning as I drove to my office there was an alert below my speedometer that said "12 volt battery needs service"; so I immediately emailed our Austin Service Manager. He got back to me right away, and said he'd have Tesla run a remote diagnostic on my car. In the mean time, he was able to reshuffle his own schedule for the day in order to make time to check my car that afternoon.
When he arrived he wasn't optimistic because the Tesla remote diagnostic had suggested that my main 10wk onboard charger was faulty, and he didn't have a spare. Hoping against hope that the 12 volt battery might be the culprit, he took the entire frunk area apart in my garage to replace that battery which is buried deep and to the passenger side of that recess in the frunk covered by the cargo net. Sadly, no dice - replacing the 12v battery didn't fix the problem.
Kudos to my Service Manager who did his best to solve the problem on the spot.
Now the next step is to have a new 10kw charger FedEx'd from Fremont, not to arrive until Monday or Tuesday at the earliest. In the mean time, my brand new $100K car can do nothing more than look pretty in the garage. Sigh!
I must confess that my previously rock-solid confidence in my Model S has been rattled by this unfortunate event. What if this had happened while I was in Houston, 170 miles from home? Or in the middle of nowhere?
Why would such an vital piece of solid state electronics crap out with only 400 miles on it? At this point we don't know if it failed because of some defect within the charger itself; or whether something else in the electrical system is defective and perhaps overloaded the 10kw charger causing it to fail. Could that "Battery is heating" message the night before have anything to do with this? Can individual modules within the main battery short out, overheat, and thus produce an overload failure in the charger?
It will be quite a while before any of us learn hard details about how Tesla manages 12v and high voltage power because the inner workings of this car are doubtless Tesla's most closely guarded proprietary secrets; yet we can be certain they're burning lots of midnight oil at Tesla as they strive for their ultimate goal of "The Best Car in the World."
I've got my fingers crossed that my replacement charger will solve the problem for good, and that my Model S will now give me at least 50,000 miles of trouble-free driving as I've enjoyed from my Lexus.

In a previous life we "burned in" our computer equipment for 24 to 40 hours (depending on where we were in the product life cycle) before shipping. Electronics suffers from infant mortality meaning literally the stuff either fails quickly or lasts for a long time. Your charger may have suffered from this mode of failure and, given the lack of posts regarding main charger failures, I suspect this may be one that slipped out the door (meaning Tesla's burn in did not catch).
Right. And after we receive it from the manufacturer, nothing critical goes into production before it's been running for at least a month--because not all infant mortality is caught during the factory burn-in.

Tesla obviously has a problem here. What irks me is that when I was on the phone with them just days ago, they said these issues were no longer reported. In fact every single issue brought up here about winter driving issues was completely dismissed.
It's time for them to step up and make some kind of announcement that there is a problem.
There will be a critical mass of these issues if things don't change soon, and when this information goes more public, consumer confidence in Tesla will decline.

I phoned before finalizing and got the same kind of answers as well. Well, you can hardly expect them to say their car has loads of problems, and I suspect that those who answer the phones are strictly limited in what they can say. You never know when Fox news will call pretending to be a legitimate customer.

Well, they had my reservation number and were reviewing my configuration. I wouldn't expect them to outright say they had globs of problems, but a little honesty would have gone a long way to engender some trust in the process.

Statistically electronics are most likely to fail when they are brand-new. Once these "infancy failures" are out of the way, electronics tend to be very reliable until end-of-life, barring a design error that causes overstress.
