This is so contrary to my experience. 75k miles over two Teslas and 3 years of ownership, never had an issue with the 12v battery, not once. I have to believe there is some common denominator in daily usage scenarios that makes one owner more likely to have issues than another. I've always had this sneaking suspicion that regular daily driving of near to 100 miles and/or the addition of an aftermarket sub that pulls off the 12v is causing some side benefit to the 12v being constantly kept happy with charging/discharging.
Maybe it's location. Jdcorbitt3 is in FL and you're in OH. Heat kills lead acid faster.
Maybe Charlotte splits the difference? I've had my 2013 for 16 months and 25k from when it was delivered (including multiple trips to Miami) and it is still on the same 12v it was delivered to me with.
