I have a 2017 Fiat 500e with 10,600 miles on it. Last month the Electric Service Light came on and I took Orange Coast Fiat in CA. The dealer indicated that a fault code P0607 was present in the ECU. They performed "Graceful Shut down", PIN reset, EMOTO reset and cleared all the codes. The light was not on any more, however it did come back last week again and the dealer said that I may need a new Inverter (?) at a cost of $8.5K. Does this sound right. The car charges fine and drives perfectly okay. Any feedback is greatly appreciated!
