Highlander Hybrid 6-cyl

  • 55,803 miles


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".

The computer on 2006 Toyota Highlander hybrid won't allow engine to start. 12V battery will not start auto until a small charge is connected to battery I have had it in the dealership 3 times with the same problem. The first time was when the vehicle was less than 1 week old - was told that I must have left a door open, and nothing was wrong with it. Second time to the dealership - same problem - same response, again, they said nothing was wrong. New battery was installed 1/1/11. Still having the same problem - car will not start-get stranded and car will not start. On 2/22/11 I took vehicle back to the dealership, along with documentation on service bulletin 01605, NHTSA item number 10015806 - serviceman said that they (the service department) do not pay any attention to any of the NHTSA bulletins that I would have to pay to have a diagnostic test. No lights left on or accessories left on. Heater, radio, seats, are turned off.

2006 hybrid highlander. Well maintained. On two occasions, the engine died without warning. Lights flashed the car stalled in heavy traffic areas. Towed to Toyota dealership. Each time the dealership said could not replicate the problem. It happened at 96,000 miles and again at 105,000. I was offered a low trade in price for an new rav 4. the dealership said they can not replicate the problem. I suggested the problem was above their feeble minds. Ill trained brains can not comprehend complex issues. It is real easy, put in an new inverter. New month I will have a larger settlement check for a business Venture. Last Toyota product I buy. I have owned 8 vehicles from this dealership. Looks like I am going back to american it was very scary on top of the interstate 12 during rush hour with a hard rain failing..

My wife was parked in front of our apartment building, idling with her foot on the brake, when our 2006 Toyota Highlander hybrid suddenly accelerated and crashed into a gate. Before the car crashed, she repeatedly applied the brake and even put the car in park. The car did not stop. After the impact, the engine continued to rev and accelerate before finally stopping. This had never happened before. The body has been repaired, but per Toyota, nothing mechanical or electronic has been touched. Last week Toyota sent a specialist out to inspect the car and download data. We were present at the time, and 5 dtc codes displayed. The descriptions displayed on the investigator's lap top mentioned vehicle speed sensors on right wheel and left wheel, the emps, body ECU switch circuit and "low or high power supply voltage". the car was test driven, and no errors or codes were reported. The car is now waiting to be taken to a dealer to be reviewed and fixed.

Have a Toyota 2006 Highlander hybrid and was driving the car less than a week ago and was on the parkway doing 65 in the middle lane and car started to decelerate, lost the power steering, could not brake nor was I able to push the pedal for the gas. Able to get to the shoulder and car stopped. Put it in drive and went to restart car, would not turn on the entire dashboard lit up with check hybrid system, check vsh, brake light etc..... brought to a Toyota dealership Thursday, still no word. States it might be an electrical problem part is approximate. 1500 to start. Theycannot even evaluate the car till they place this part in. Sounds costly to me. Went on another website, appears that other owners of the 2006 Highlander hybrid have had similar problems when they are over 100,000 miles. October 4 email:"finally got my car back after 3 weeks. They put in a new control panel and inverter, I paid $1400 for the control panel and was compensated for the $8800 inverter. Plus they fixed a steering wheel recall and the rear brakes were shot (my fault). [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

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.

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.

We have a 2006 Toyota Highlander hybrid. There are a number of minor but annoying problems: 1) battery dead in morning 4 or 5 times for no apparent reason. 2) after turning off engine and opening door, buzzer occasionally goes off for no apparent reason. 3) some radio stations pick up a lot of static when brake pedal is pushed. 4) dvd carousel player picks up errors when attempting to play disks four or five. Wrote a letter to Toyota in 2007 regarding some of these issues but got no response. These problems could be related to the electronic issues we have recently been hearing about.
