My 2006 died with an inverter failure a few months ago and your experience sounds like mine. Beware of multiple failures as a result of this event! Once Toyota replaced my inverter and Hybrid ECU, there were still multiple error messages. They told me that my power steering ECU had also died and needed to be replaced for $1,000! I told them that I felt the Hybrid failure had cause this and they told me, with a straight face, that my vehicle must have been struck by lightning and that is why I had multiple failures. They replace the power steering ECU and then discovered that the ECU for my climate control was ALSO bad! Another $1,000 repair at that! I did not have it repaired and traded it for a non-hybrid Highlander at a different dealer. The service writer at my Toyota dealer actually told me that I should get rid of it, after he told me that it had been struck by lightning! No evidence of a lightning strike, but they stuck to their version.
I would say that you need to get your vehicle to a Toyota dealer and have them replace the inverter and likely the Hybrid ECU. Any other problems are likely caused by a lightning strike! No kidding! Good luck.

Depending upon the VIN number, it might fall into the recall batch. Even if it doesn't it's the same problem and they should fix it at no cost. I believe, the printed circuit board that controls the inverter fails due to improper soldering.
When that happens the entire inverter is ruined. You might be able to find out on the internet. There definatley was a TSB that you should be able to find.

Had the same problems as you, read past posts....Toyota will not help you, we tried everything with them. They told us the reason the inverter went out was because we did not maintain good service, we did, and have the records to show...Only thing left to do was to file a class action law suit, which we did, Thalberg v Toyota. Might take a while but hang in there...

Thanks for those that replied. Reputable mechanic (D&K Automotive Repair) in Leander, TX towed the car for me, tested the engine start battery and found it to be bad (would not hold a charge). They replaced it with the 3-year replacement battery for only $85, but said the remainder of the issues appeared to be related to the Hybrid system, which they could fix, but recommended I have the vehicle towed to Toyota instead, as they should fix this under warranty, cover the towing charge, and pay for a rental vehicle.
First and foremost is finding a shop like D&K that will be honest with you. They could have taken me to the cleaners, but did the right thing.
Vehicle is now at Champion Toyota in South Austin. Looking forward to tomorrow's diagnosis and a serious discussion with the head of the service department. Doesn't hurt that one of their master Hybrid technician's was the coach of my son's soccer team. Will fill y'all in once I talk with them.

Had the same set of circumstances as most of the other posts. We were stranded at night in a rural area with no street lights around. While we were standing away from the car (because we couldn't get it totally off the road) someone who couldn't see us in the dark actually tried to break into my car. Dealership says that the diagnostic indicated failure in all 6 ignition coils, but they offered to try to fix it by replacing one coil??? They also indicated that they had "checked" the inverter and it was fine. Anyone else hear this?

As it turns out, my circumstances ended up with the exact same result. They said the the ignition coil on one cylinder needed to be replaced, but they didn't have any in stock. Had to order and wait a day. When they replaced the ignition coil and told me the car was fixed and ready for pickup, it then ran like the engine was miss firing. Took it back and they told me that coincidentally, on a different cylinder, a fuel injector had debris in it and that I must have gotten bad gas. Curious huh? After everything was working totally fine before the incident, now all of a sudden after replacing a coil, a fuel injector starts acting up. Total bill was just under $600 including a $140 towing charge, and $90 for a rental car.
They admitted that they have started to see coils go bad around 90K miles, but not this early (around 75K miles). So are the coils all going to go bad at 90K miles?
Fingers crossed this doesn't happen again!!!!

My car as 56K, not near 90K yet. At this rate, it'll never make 90! It is still at the dealer so I have no resolution yet. I would be happy if changing one coil fixes the problem, but I'm certainly not confident that it will. I'm still wondering the explanation for ALL coils failing at the same time if it's NOT the inverter???

I just registered on this site and am trying to catch up on this thread.
I bought a '06 Toyota HH a couple months ago with 113k on it. The inverter had been replaced under warranty in 08/10 (83k). Everything was well until the "Check VSC System" and "Check Hybrid System" popped up last w/e. The dealer said that there is no remaining warranty and wanted $550 to diagnose the HV battery. It appears that hybrid system is covered under a 8/100 but the battery is 10/150, maybe. It is a CA car. I spoke to Toyota directly and was told the battery was 10/150 and they were going to FAX me the documentation. She then called me back and said that she had made a mistake and it is not covered (Prius and Camry are, but not the HH). She apologized and said that she would open a case, esculate it, and assist however possible. I am awaiting a call from the case manager.
Anyone have any suggestions?
Thank in advance.

Paid over $500 last year to have one ignition coil replaced - just had another go out while driving. Have now paid over $1000 to replace all coils since both went out while driving and could cause a fatal crash. GM of dealership told me I should have bought an extended warranty - what a crock - split the cost of replacing all coils with me. I am reporting this to Nat. Trans. Safety Board as this is a dangerous defect. Of course, my car was just out of warranty when the first coil went out-go figure.
