Long term results report. I had my invertor replaced september 3, 2010. So far it has been bullet proof. Toyota fixed this $10,000 repair for free. Basically it is a faulty invertor , recall # 87559
June 29, 2011. This was at 64,000 miles and I am now at 96,000 miles with everything working well. I had to do the timing belt, tensioners, water pump , as part of the recommended 90,000 mile maintenance. I also had to do a radiator and front control arm bushings so this was a major bill. I did switch tires to Yokohama Parada's so the car rides very well but thye are not the longest lasting tires. Gotta figure if there is a cheaper way than a lexus dealer. But in thinking of doing all this work I decided this is a overall very reliable car and worth doing as the car rides well, looks good,
and is nice to drive. I figure the Prius 's I have seen used as cabs are going over 300,000 miles so there is some precedent for long term ownership. Yes I would buy one again ( and I guess by fixing it I am planning another 90,000 miles , I hope ! )
Lexus service is expensive at times . The timing belt - water pump fix is costly. If the invertor has not been done , get the dealer to do this as it is a recall safety hazard. It's a Hybrid so we all hope Toyota stands behind this technology !
