I too was concerned about this poorly designed inverter problem. I opted to purchase an RX330 with 103k miles instead of a hybrid. Runs beautifully. She still can use unleaded vs. premium fuel and gets around 25mpg if we baby her.
The only downside to purchasing a used Lexus is if the previous owner has not done their regularly scheduled maintenance. Repair costs are, well, shall I say significant at Lexus Service centers?

The inverter has been recalled, and Lexus will replace for free. At least on the 2006 model.

After learning that the inverter is a ten thousand dollar part, I would no longer buy the hybrid model either. Apparently, going green has it's downsides. Wind power also uses inverters (solar too), if the wind speeds are too high for a sustained period of time, you can burn out a 4-6 thousand dollar inverter. So, for wind, you have to really match wind speed to the inverter (for efficiency). This means "dumping wind", during highly sustained gusts or storms.
I wonder if high sustained freeway speeds can cause these inverters to burn out. If they built these to have a maximum efficiency at 60 mph can 80 mph over time burn out the inverters?

Last Thursday I had the very unpleasant experience of having my 2006 Lexus rx400h completely die while I was on the freeway. It was towed to Lexus and I was told my inverter water pump is dead. They are quoting me $1200 to fix it. They won't be able to tell what else might be wrong, such has the inverter itself completely failing, until the pump is installed.
I called cooperate lexus and as of right now, I'm not overly thrilled with their response. I flat out asked that if once the new pump is installed and we find that the inverter is still working, will they not replace it in spite of the many documented failure cases? No was the reply. So essentially the inverter will need to completely fail, possibly while I'm driving and not able to pull over with possibly hurting someone or myself. Nice lexus . . .
#106 of 110 Brake Calipers replaced
Dec 04, 2012 (12:09 pm)
For a while I have had a rattle/rumble from the rear of my car especially when going over bumps. No one could diagnose the problem and eventually I took it to a Lexus dealership (there isn't one in Charlottesville!) who told me that I needed to replace the rear brake calipers which were loose. Apparently they couldn't tighten them as a rubber bushing had failed. So $1,200 later I have new brake calipers and rattle has gone. The service dept. said they had never seen this problem before. Of course it's out of warrantee by about 12 months! Why should I need to replace the calipers just because a bushing has failed? Anyone else have this problem?

I did not have chance to update about our car but the dealer kept it for about 3 weeks, said drive fine everyday, could not find a problem and could not simulate the problem. They said the battery was actually fine but they changed it anyway (changed it twice within a year). Meanwhile we talk to the corporate to sell the car. Although the car is certified pre-owned, they couldn't help much. We told the dealer that they can't simulate the problem is already the big problem. They gave us a low price, we lost a lot of money but we just felt bad to sell this kind of car directly to someone by ourselves. The dealer even said 'Now we can't tell this problem to the sales person!' and put 30% mark up on and is selling it. I can't trust this model. We owned Prius twice, never had any problems. One has 120k miles on, still fine. Prius has been made a lot and been around long time, probably more reliable. Guess what? We purchased Prius again. I will report this Lexus to the government. We should not bare this kind of problems for such expensive cars!!

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 they 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 ! )
#109 of 110 P0AA06 code & Check engine light warning/water damage from seam separation
Jul 05, 2013 (9:17 am)
Our Lexus displayed a check engine warning and P0AA6 Code and then immediately stopped working. Upon inspection at dealer, the entire bottom floor of the cabin (under the floor boards) was flooded without any visible water damage inside the cabin or any visible point of water entry. We were given an estimate of approximately $11,000 to repair because the entire hybrid battery system had to be replace, inverter and other components along with the interior carpet had to be ripped up and replaced in the process. It turns out water was entering from very small fractures in the seams by the trunk door stays. These are not visible to us unless you are trained to know to look there as Lexus mechanics have been trained. Upon researching this because to me this indicated there was a manufacturing defect if the seams do not stay sealed and over time separate, there are two TSB's specifically addressing this issue. L-SB-0019-09, issued March 10, 2009 and L-SB-0045-09, issued April 29, 2009. In order for a TSB to be issued Lexus has to receive a threshold number of complaints on this issue. Lexus then investigates and comes up with a solution to correct this problem. TSB's are part of a computer data base available to service technicians so they can look it up and determine what may be allowing water intrusion and how to repair. Apparently, there were enough complaints of flooding and it was determined these seals were not holding and allowing water to come in over a period of time. The problem is Lexus did not issue these TSB's until well after most of the covered vehicles (2004-2009 models of three different Lexus cars) were out of warranty. Lexus also chose not to tell its customers of the potential for the separation and magnitude of damage that can happen from this defect. The repair to seal the seams is only a few hundred dollars compared to the damage you may suffer, in the thousands of dollars, if the leak goes undetected until the hybrid system shorts out. There are no warnings and your vehicle can shut down abruptly with the potential of severe harm to you whenever water gets into an electrical system. Lexus really dropped the ball on this one but is benefitting greatly by having you over a barrel once the damage is done and you have to pay for the repairs. Lexus did immediately agree to cover the battery without a complaint from us. However, when we went to customer care and complained that Lexus knew of this defect and refused to do any preventative notification or recall we only received a token $600 more. I then went to corporate who flat out refused to help us and would not accept responsibility since the car was out of warranty. We did not want to put the claim through insurance since the car would then be labeled as water damaged/flooded and be of no value on a trade in/resale. We got stuck with a $4000 bill for damages that could have been prevented by a simple notice from Lexus advising of the potential for damage and suggesting we have the seams resealed. We would have gladly spent a couple hundred dollars in preventative care then face the damages we just had to assume. Anyone who has experienced this needs to complain to Lexus and voice their disappointment!
#110 of 110 flash flood damage to hybrid engine and battery 400h 2006
Jul 18, 2013 (10:46 pm)
58,000 miles, excellent condition and maintenance for my 2006 400h Lexus then a flooding at an intersection caused hybrid engine and hybrid battery to need to be replaced which is being done now. my insurance covers these costs but I am concerned that the Lexus dealership in Florida will use refurbished or recertified parts instead of new parts. The car has been in the "shop" for 5 weeks so far and expectations are that more weeks will be required before the replacements have been received. Is this unusual ?
