Thanks for your insight. Can you sight the US Federal Warranty Regs on EV batteries, specifically the Degradation Limit of 70%. I've founds lots of info on the "8 years / 100K miles", yet that seems to only be for complete battery failure, and does not state any degradation limit. I would like to be more informed when I discuss this stuff with my Telsa neighbor, as his experience has him selling his cars after a few years. Maybe he has some type of warranty claim with Telsa? Or is this Federal requirement something new for 2023 models?
Thanks!!
The way I understand it, 15 U.S. Code § 2301 (emissions law) covers these components, but I haven't seen the exact language everyone quotes for 8 years / 100k. CARB also has warranty rules in place, and are currently pushing for 10 year 150k miles. I do not believe there is language that guarantees the amount of performance retained, but almost all manufacturers have settled on 70% as that number. Nissan is the only weird one with wording like "displaying less than 9 bars out of 12 on the battery indicator". Tesla's battery warranty is 70% for 8/100k on Model 3 & Model Y, and 8/150k on Model S and X. https://www.tesla.com/support/vehicle-warranty
Maybe your neighbor should have kept the old cars around for a while, prior to 2015 Tesla had an unlimited-mileage warranty on the battery and drive units.
