Did you try to get trade in estimate?I have about 60k miles on my 2012 Sig red 85kwh (#708) that I have now passed the 8yr extended service agreement as well. Last week I got a fault alert for the 12 v battery so I scheduled a service appointment. Two days ago it now is reducing max power and all regenerative braking. The service center in Superior contacted me and now tells me that the HV battery is bad and that it’s 15k, customer pay since warranty expired. I agree with the above poster in that I feel over a barrel. I was not ready to sell my car for scrap but am very nauseated by this sudden cost that seems to have conveniently fallen immediately (ok 5 months) after the warranty expired. What option do I have?
