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.

While in the mountains in heavy traffic, the vehicle all the vehicle warning lights went on and the vehicle shutdown. While negotiating the vehicle to the side of the road, I barely avoided an an accident with another vehicle. I turned the vehicle off and it restarted and drove it to a mechanic who disconnected the battery and all of the vehicle warning lights disappeared and it drove fine. It has happened twice since including today (July 7, 2015). Was told by mechanic that it was likely an inverter that would cost about $10,000. While checking the Toyota recall website, I noticed that there were a number of other recalls involving inverters and electrical system malfunctions in 2006 Toyota Highlander hybrids but was told that these did not impact this VIN #.

I had closed the windows to discover the rear passenger side window was stuck in the down position. I had written to Toyota regarding this on 08/29/2012 their response -they had no data to share on what complaints they receive to provide to the public as that is proprietary. Toyota sent it to their national headquarters, giving me a file #. the window is now stuck again. And happened another time since 08/28/2012 I just searched Toyota power window controls, there is a recall, dated announced October 10, 2012, they are saying certain models 2007-2009 highland and more. If Toyota did send my complaint to their headquarters a month and a half earlier, they should have checked their records, this has happened to other 2006 Highlanders.

Our 2006 Toyota Highlander hybrid would not start on several occasions. The car had been running for some time, turned off for 5 minutes and then it would not restart. After sitting for a few hours it restarted. Some times it had to be jumped and the code read "shift to park" even though it was already in park. I took it in and everything checked out and of course they said that they never heard of this happening before.

I went to the dealer related to NHTSA campaign id number: 11V34200. The dealer check the Highlander and said that the recall not apply and did not need to be installed or repair the inverter. The next week ll the panel warning lights turn on(brake, slip, vcs warning, exclamation sing and ABS). Then a return to dealer, they check the Highlander. Now they said that the problem is the ABS module. How I can corroborate that my car is not included in the safety recall.

Highlander 6-cyl

  • 62,000 miles
I was driving in my Highlander with my daughters in the back seat when suddenly out of no where all the alert lights came on and there was no power at all - the gas pedal was non functional - I was in the far left lane of a an interstate and fortunately I was able to get off the road and pull the car out of traffic as it rolled to a stop. I waited on the crowded interstate for two hours for a tow. I was told that the Highlander hybrid inverter had failed - the dealer replaced the part that week and the car drives normally now. I was advised that in fact this is a known problem. One month later ironically I received in the mail notice from Toyota that my model of Highlander is being recalled for the inverter replacement that had just caused this extremely unsafe vehicle failure just one month prior.

Highlander 6-cyl

  • 35 miles
Vehicle Toyota 2006 VIN #[xxx] Highlander limited prior complaint sent to Toyota & dot 2/4/2010. After a stop when accelerator sometimes there is a second or two pause before the engine responds causing a sudden lurch forward. Additionally when diving at in town speeds and the accelerator is released and then a resumption of pressure on it there is a second or two pause before the engine engages, also causing a lurch forward. I have learned to "expect the condition" and make allowances for it, however it still causes concern and possibly a dangerous acceleration. The accelerator and engine activation need to be corrected for this "pause and lurch forward response". parts of this document have been redacted to protect personally identifiable information pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

2006 hybrid Highlander reported and went to mediation with nothing done. Car has lots of issues, it jumps forward when stopping about 3 feet on occasion, it will go dead for no reason, the gps fails and puts you in pa when in va, and electrical and mechanical nightmare, had written testimonials but they ignored it saying all tests were fine and it started when the car was only about 3-5 months old. I went on htn meds because of this and am afraid to drive car and had to buy another for my kids to drive as it is not safe. There are website with lots of others with the same issues being told all along that noone else reported it but they all did...please help!!

Re: 2006 Toyota Highlander hybrid 2wd SUV 29,500 miles. Upon entering a highway I experienced total failure of the hybrid system in my SUV, which slowly drifted to a halt, nearly causing several accidents. The nearest dealership replaced the inverter portion of the hybrid system. It was covered under warranty but I was told that had it not been covered it would have cost me between $9,000 and $10,000! or about 1/4 the cost of the entire vehicle new!
