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?

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.

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?

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.
