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).

38 Electrical System problem

Failure Date: 09/04/2010

Driving in 6 lanes of heavy traffic we heard a 'thunk' and lost all power. I wrestled the vehicle to get it to coast off of the road. Car was towed to Toyota dealer where it was found that the inverter needed to be replaced. Cost was $7600, after a substantial discount from the dealer, who was obviously embarrassed about charging so much for a single part. The incident could have caused an accident, since all power and electrically assisted driving functions failed simultaneously. Fortunately it didn't. Subsequently I found that Toyota had upgraded their inverters beginning in 2007. We have also received in 2011 from Toyota an "interim safety recall notice" for the inverter, but have heard nothing since.

40 Electrical System problem

Failure Date: 08/16/2010

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.

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. .

45 Electrical System problem

Failure Date: 06/07/2010

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.
