So I just bought a used higher mileage tesla model s from a private owner - he assured me that he had the extended warranty and that it conveyed to me by simply calling tesla and informing them of change in ownership and providing associated verifications ... I call tesla ... They stumble and bumble and call me back to inform me that starting in 2016 extended warranties no longer transferred and that instead they are allowing the previous owner to submit a claim to receive a prorated amount of what they paid back ... Is this true ? After all this talk about customer service and how extended warranties positively affected value could the company simply change the rules without appropriate notifications and leave folks like me high and dry ... All, please chime in and help me understand what's going on!?
