Hi, I'm a new member. I've had my (2007) RX400h for a few years - easily the best car I've ever had. Now I'm facing a problem with the hybrid system (error code P0AA6). I've done some research and it looks like that error code is highly likely to be telling me I might need to replace the hybrid battery. I'm told the hybrid battery life is between 10 and 15 years, and the car is 13 years old now. The Lexus dealer will charge £3000 for a new hybrid battery and £1000 labour, so I'm trying to come to terms with maybe having to write off the car - which would be such a shame - but does it make sense to spend £4k repairing an older car, which is only worth around £4k. I did wonder if the hybrid system could be permanently disabled so I could run the car for the rest of its life on the petrol engine but the Lexus dealership says no, technically not possible because all the electrics work off the hybrid battery, not the 12v battery - which is just used to start the car. I'm looking for ways to get the car back on the road at a lower cost. I'm trying to research whether hybrid batteries can be repaired or if you can get second-hand or reconditioned batteries - finding it difficult to get much information on that. Financially this couldn't have come at a worse time and we're a one car family, so I'm hoping someone might suggest some options I've not thought of, or point me towards where I can get some more information. Thanks.
