I'm researching inverter failures for 2006 Toyota Highlander Hybrid. Similar story to others here. A dangerous complete power failure while driving. 9K+ estimate for replacement. First hybrid after many Toyotas in the family. Thought we were doing the right thing, even with the higher up front cost. Bragging the DAY of the failure this car was the best we ever bought. This is not right. My guess is that the Lexus 2006 inverter is the same part? Does anyone know?
#28 of 110 Please report your inverter failure

Please report you inverter failures as skycaptain suggests. Toyota refuses to give any information regarding these failures. Only consumer outrage will force them to respond.
Office of Defects Investigation (ODI)
Only takes a few minutes. Have your VIN number handy.
Some of us have our vehicles at dealers waiting repairs so this DOES matter. Please report your failure even if it was covered by warranty. Don't let Toyota get away with this dangerous and costly defect.

Just purchased the RX450h with the navigation system (ultra premium) and I have experienced what I believe could be problems with the hybrid and 12 volt batteries.
First instance after acquiring the car, I started to set up some of the car functions through the navigation screen with the car on accessory/on. After a few minutes of setting up the various functions, everything went blank and could not start the car. However, after a few minutes, I was able to start the car. This happened on more than one occasion during the weekend.
Second instance:Parked the car in the drive way, parking brake on, all power off; after washing the car with a pressure washer, including the inside of the mags, I could not start the car. Both 12 volt and hybrid indicated fully discharged after I finally got the car started. On the navigation system, which shows the status of power, the hybrid has only the two lowest bar on the graph, and the color was violet/mauve. Took the car for a spin, and everything appears to have returned to normal. Are those signs of something much serious. Looking forward hearing from others who may have experienced similar problems with the RX450h.

Have you experienced any problems with your new Rx450h, and if so, what were they.

I've have found the VIN break for the change from the defective inverter to the new part. Before the break you may experience total power failure, engine, steering and brakes. After the break the new part does not have any failures I can find.
Toyota 06 Highlander Hybrid 2wd - Ending in 60009725
Toyota 06 Highlander Hybrid 4wd - Ending in 60019910
Lexus 06 Rx 400h 2wd - Ending in 60002207
Lexus 06 Rx 400h 4wd - Ending in 60036526
My dealer did the right thing and brought my bill from $9000 to $1200, but how many owners are still driving these dangerous cars??
#32 of 110 RX400h Check Hybrid System, Check VSC system
Aug 04, 2010 (10:25 am)
2006 RX400h, 51k miles, live in Houston, TX. Driving 65-70mph on Hwy 290 on July 30 and my car completely shut down (exactly the same circumstances as others have described). Check Hybrid Sytem, Check VSC system lit up on the dash. Car shut off, steering was difficult, brakes worked slightly. I pulled off on an exit and stopped the car. The lights, radio, power windows, etc. were all still working but the car would not work. When I shut it off and turned it back on, the READY light came on for 1-2 seconds but the car never did start again. While waiting for the tow truck, I left the key on to run some AC but it drained the battery within 20 minutes. Just received word from the dealer that they need to replace the inverter and it is covered under warranty. My 4 year warranty on the car has expired but the Hybrid system has 10 year/100k mile warranty. Thanks to all others who posted. This site was a savior to me so i could talk intelligently to my Service Advisor.

I'm beginning to think I have the same problem.. I bought our 2006 rx 400h with only 6600 miles on it from the Lexus dealer. It now has about 60k on it.
It started having starter battery troubles almost immediately. Had to be jumped if I left the four-way flashers on for a few minutes, and would not start occasionally, so I took it in several times to dealer and they said they couldn't replicate the problem, that it operated normally while it was in the shop. Finally, it wouldn't start in their driveway and they quickly put in a new small battery (the starter battery).
It's been fine now for a couple of years, but last week it started acting funny, wouldn't start first try, and would tell me I needed to shift to "park" before starting, well, I was in "park"!! Then I jumped it and it ran fine a few days. Now it won't start unless I jump it. Am taking it in tomorrow.
I'm curious, maryland john.... how did you come by the VIN break list? I'd like to walk in the Lexus dealer tomorrow AM, armed with as much ammo/info as I can. I don't want the same run around as I got in the past.... thanks

Driving off a stop light and the car just died. Check AWD - CVT - Hybrid system warning lights went on . Towed to dealer next morning and they called to say lucky it is under warranty ( I have 64000 miles , warranty is 70 k ) and it needs a new invertor. I have not seen bill but here it is $ 7 to $ 9000 Yikes ! This is a problem as it shakes my faith in Lexus Bought from USA to bring to Canada and relied on toyota - Lexus brand Will report to NHTSA and Canada Transport as this should not be happening and from what I can see the toyota lexus hybrid system needs a longer warranty !!!!
Spread the word !!! Complain !!!

Yikes! $9K for a single bad part on the RX 400h?
Thought about buying an RX 400h, but now no way!
Thanks for your info. Wonder if the Prius has same problem?
Let us know if Toyota changes the design.
