One problem related to battery propulsion system has been reported for the 2015 Tesla Model S. The most recently reported issues are listed below.
There is a flaw in the Tesla emmc which will inevitably cause a critical portion of the chip to fail prematurely, due to constant excessive logging within the touchscreen system. Ultimately the memory chip fails and the touchscreen goes black, placing the car in limp home mode, the parking sensors and rear view camera no longer work, it will not charge and effectively becomes un-drivable when the battery runs out. The emmc is a linchpin component for the functionality of the car. The emmc, though it does not control the car's propulsion, braking or steering, is the heart of the touchscreen which is used to turn on headlights, adjust hvac and all car settings run through the touchscreen. The hvac unit now has a "dog mode" which keeps the cabin cool for dogs or occupants waiting in car. The failure of the touchscreen unit while in dog mode could result in heat-related fatality, should an owner.
