I sent Tesla an email because I was only getting 90kwh out of the new Springfield, OR 120kwh chargers. I was told today that my car is older and doesn't support 120kwh. I'm rather steamed about that. Nowhere that I can find has Tesla ever said newer cars had different support than older cars. I asked about an upgrade. Doesn't know. Would an upgrade be part of the "hardware upgrades" mentioned in my prepaid service contract? Doesn't know. If someone bought a used Tesla or activated SC on a 60kwh, would they know if it was 90 or 120 enabled? Doesn't know. I'm not particularly happy about the 90kwh limit and particularly by the complete lack of information conveyed to anyone about the fact a difference existed or how to find out. This certainly dims the resale value of older Teslas. He said he'd call me back when he found out more information, but I'm not pleased. I'm seriously regretting purchasing when I did rather than waiting another few months (VIN P02310).
