I am wondering how the high mileage owners deal with the 12v battery. My X just died after 2.5 years and 41,000 miles. Couldn't open doors etc. Bad hydrogen sulfide smell, so possibly leaking and not due to just a "dead" battery. There was no warning. I had just gone out and picked my daughter up 90 minutes before I went to check on my X. Tesla service called a tow truck, he was able to get it charged up over several minutes so he could open doors and back up to load on truck. My issue is, when the warranty expires, I don't want to have to pay for a tow truck to take it 45 miles just to change a 12 v battery. What options do I have? As most of us have done, in our old ICE cars, take the battery out, use another car, go to auto whatever store and exchange for a new battery. Drive back home and pop it in. Do I have them preventively change it every 35-40k miles at a service visit, do I learn how to change it, ????
