Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Highlander Hybrid 6-cyl

  • 92,100 miles


I was pulling into our driveway and when I pressed the accelerator, the car stopped and began to roll backwards. All of the warning lights came on along with a warning on the lcd panel that stated "check hybrid system" and "check vsc". it was towed to a Toyota dealership. They indicated that the hybrid inverter and esu had failed and they replaced them. The vehicle still displayed several warnings and after searching for almost 1 week, they determined that the power steering esu was also bad although this was not the case prior to the hybrid failure. They said that the 12 volt battery also needed replacing although it was only 8 months old and was purchased at the dealership. When I asked how this could have happened, I was told that the vehicle must have been struck by lightning! October 1, 2011 in our state was a beautiful, clear day as it had been for a while. I suggested that the inverter and esu failure caused the power steering esu failure, not a phantom lightning strike. My vehicle is currently still at the dealership as I await their reply. Hybrid components are covered under the extended hybrid warranty but the steering esu is not and will cost $1,000 to replace unless Toyota will accept that the failure of the hybrid components could have caused a powerful electrical surge that damaged the power steering ECU as well as the 12 volt battery.

There have been four incidents with this vehicle in which the hybrid system shutting down. The first three times the vehicle was fine when I turned it off, but would not restart. With all three of these incidents the vehicle would restart with no issues after a few hours. The csv and the check hybrid system lights as well as most of the panel lights would come on. The dealership checked it two times and said it was fine. In the most recent event, I was waiting at the bottom of a driveway. When I went to proceed I pressed the accelerator and the engine made a loud sound that seemed equivalent to it running at a high RPM. The car would not go forward or reverse. I turned the car off and then on again, it made the same sound and again did not move. The csv and the "check hybrid system" lights as well as the panel lights came on. I rolled the car out of the driveway and turned it off again. Due to the previously described history of the car, I chose to wait an hour before trying to restart it. After waiting an hour, I attempted to restart the car and the exact same things happened. After putting the car on the scope the dealership could not determine the problem. I was called after two days of the dealer running many tests and told it was the inverter. The price quoted to me was $8000. I insisted that they needed to look into the Toyota recall of the hybrid inverters. I was told my vehicle was checked by another dealership on August 15,2011, and it was "cleared." I asked them to recheck this recall to see if my car fit into the category. I was informed they were not going to recheck it, but they would instead contact Toyota. Had this happened while I was driving up or down my driveway, I would most certainly would have gone over the 50 foot embankment on my driveway or the cliff directly across the street from my house.

I was backing out of our driveway into the middle of the street & the vehicle died. It couldn't be started & the gearshift could not be moved into any other gear, therefore it remained in reverse. Nothing electrical would work either & the car's interior is fully electric, (windows, door locks, nav, seats, radio ect). The "check engine" message was on. At first we thought it was the battery, as per tow truck driver. The car had to be towed. First towed the car to get a new battery but after installation of the newly purchased battery, the car still was inoperable & had to be towed again to the Toyota dealer. This was an additional out of pocket expense. The dealer replaced the "inverter" & something listed on the receipt as "super long life C".

While driving on major expressway I lost all power and was (thank goodness) able to safely coast to shoulder. All the warning lights lit up together with the alternating messages: "hybrid system failure" and "vsc failure." The car would not restart. I was fortunate it was a Sunday morning and I was able to safely reach the shoulder. The expressway I drive Monday through Friday (I-595 in broward county Florida) is very heavily traveled and, due to construction, has many sections without a shoulder. My 2006 Highlander hybrid had to be towed. I was advised that the hybrid inverter, a $7,000 part, had failed.

The inverter ( a very expensive electrical component) on my 2006 Toyota Highlander hybrid failed resulting in a complete loss of power on the highway. The car was towed to dealer. It took a week to diagnose and repair. Repair was covered under the extended warranty that applies to hybrid components. I have asked, but Toyota can/will not tell me how often this type of failure has occurred; the internet has stories from others who experienced this type of failure. Complete loss of power on the highway is clearly a safety issue. With Toyota's reputation, I can't help but wonder if this is an issue that they don't want discussed.
