Known issues

Medium
Warranty terms depend on when the car was bought. Tesla's warranty effective January 29, 2020 gives Model S and Model X 8 years or 150,000 miles with at least 70% capacity retention, and says cars bought earlier keep the terms in force on the day they were bought.
Medium
Tesla's 2018 Model S and Model X warranty covers the battery for 8 years with no mileage limit, except the original 60 kWh battery built before 2015. It carried no capacity guarantee.
Low
The 60 and 60D sold for 2016 and 2017 use this pack. Tesla's EPA filing describes the Model S 60D as a dual-motor car with a firmware-limited 75 kWh battery pack.
Low
From March 2017 Tesla told EPA it was adding a second battery to the 75 carline, a 100 kWh pack module with depopulated cells and firmware limits to match the 75 kWh pack, while still building the existing pack. Its pack test measured 73.2 kWh on the standard 75 and 79.7 kWh on the new one.
