The warranty for our 2012 S P85 says that we have 8 years from the date of delivery for our battery warranty. Tesla is now telling us it is 8 years from the date of production. That's not true, when we purchased the Model S CPO our warranty stated "8 years from date of delivery". Tesla is now telling us the Date of Delivery has been wiped from the log and they can't tell us what that date is. However they are telling us the Date of Production was December 2012 meaning we are out of warranty for battery replacement. Has anyone dealt with this? Seems like wiping the "Date of Delivery" from the log is suspicious and fraudulent IMO.
