that's why storage voltage is cited at 3.6V per cell (30-40% state of charge). That allows you to leave the cells for over a year without having to maintain them.
A properly designed BMS in shutdown, will draw very little current, and will deplete the battery at a slower rate than natural leakage.
So, it is certainly possible for a battery to die on it's own if you fully deplete it, and then park it for a long period of time. There's nothing that Tesla can do about it if you're that intent upon damaging the pack.
