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.
