Thanks for that! And yes, I agree - if other countries have warrantees that cover the complete hybrid system, so should Australia. Apart from anything else, if the car was travelling at speed, the failure of this inverter could be catastrophic. All of a sudden it's a complete systems failure - and I've read that this has happened before overseas. Ours was parked on a steep hill and when I tried to start it the system went haywire and it wouldn't engage gear so it very nearly barrelled in a car down the hill. Who knows what this Australian warrantee aberration will do for the resale value of a Lexus Hybrid in general. I'll let you know if I have any progress to report.
