I have an 06 Toyota Highlander Hybrid with 64,900 miles on it, we were driving on interstate 5 south on central CA, suddenly vsc and check hybrid system flashed on the instrument panel and the car was totally dead, tried to start it a couple of times but to no avail. The car was towed too a nearest dealership and the problem was the hybrid inverter. 2 days before the incident the car's battery was totally drained, not a single light will turn on. I jump started the car to make run. The inverter was replaced under warranty and it would have caused us $8200 w/o installation to replaced it if it was not covered under warranty. I did some research and found out that a lot of people the same problem with their Highlander Hybrid inverter failure. This can happen anytime again w/o warning and could lead to accidents , and I don't feel safe on driving this car again.
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".
