    Just went through this myself after 7 months/18K miles and i'm hearing of more and more owners having their 12V batteries replaced, sometimes up to 3 times. How big a problem is this?

    If you have had a HV battery replacement it will include a 12V too (pretty sure in all cases?)

    Both times done pre-emptively by the SC when the car was being serviced for something else.

    I've had mine replaced as I noted recently on another thread, but be cautious of the selection bias here when viewing the results. People who haven't had 12V battery issues would be less likely to click on this thread and answer the poll.

    Once preemptively by Tesla service (after about 6 months of ownership). Last month, because of the Alert message

    Once, proactively by Tesla, just a couple weeks ago. Never had any problems with it since getting my car Feb 2013.

    Who is the supplier for the 12v batteries? Anyone taken a look at the markings on the battery or batteries? If you've seen both the original and the replacement, is the replacement the same brand?

    Bought the car a year ago and just now got the 12V alert. Tesla is replacing the battery. For free, I assume.

    Twice since Dec 2012 - increasing vampire losses were a clue the second time.

    I think you are very right on this. I happenstance onto this thread while reading this quoted statistic of '75% of Tesla owner respondents have had their battery replaced at least once!" This surprised me since I've met so many fellow Tesla owners, and only one mentioned having a [12 volt] battery problem.

    I had mine replaced preemptively a while ago, but it went again the other day in a less than opportune situation:
