テスラModel Sのドライブユニットに対する保証がバッテリーパックと同等となるよう延長されました。つまり、最も人気のある85kWhのModel Sのバッテリーパックとドライブユニットの両方は8年間、走行距離に関わらず保証されます。また、保証期間中に何度所有者が変わっても保証内容に変更はありません。
Moreover, the warranty extension will apply retroactively to all Model S vehicles ever produced. In hindsight, this should have been our policy from the beginning of the Model S program. If we truly believe that electric motors are fundamentally more reliable than gasoline engines, with far fewer moving parts and no oily residue or combustion byproducts to gum up the works, then our warranty policy should reflect that.
To investors in Tesla, I must acknowledge that this will have a moderately negative effect on Tesla earnings in the short term, as our warranty reserves will necessarily have to increase above current levels. This is amplified by the fact that we are doing so retroactively, not just for new customers. However, by doing the right thing for Tesla vehicle owners at this early stage of our company, I am confident that it will work out well in the long term.
