So the Model S/X have an 8 year/unlimited mile Warrenty in the drive train and battery pack. By all accounts the number of drive unit replacements is way down and the battery capacity losses are very low. On the order of (at most) 8% over 100,000 miles. Now battery packs are expensive even with Gigafactory cost reductions. With the volume of Model 3 orders, I wonder if Tesla will have a lesser Warrenty on these items for the 3. I heard (not sure if accurate) that the Warrenty covers you for a new pack if the lose is greater than 20% over the Warrenty period. That is awesome if you are a high mile driver. Comparing that to the Leaf (what I am familiar with) 8/100,000 on the pack against Cell failure 5/60,000 from premature loss of greater than 66%!!! Now Nissan has some loss issues but that is a tough number to make in that timeframe. Now for comparison, a guy just hit 150,000 miles on his Leaf in temperate OR and only has 50% capacity left!! So Tesla has a great battery but what are they gonna offer? I bet it will be something similar to the S now but more like their original 8/100k.
