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.

2004 Toyota Highlander Owner Comments

problem #5

Highlander 6-cyl

  • 78,000 miles


I took my 2004 Toyota Highlander V6 to longo Toyota for brake booster recall in November 2010. They kept my car nearly 7 weeks before repair was completed. A few days after picking up my vehicle, while I was parked dropping off my passenger, most of the control panel lights illuminated (brakes, ABS, trac off, vsc, check engine). I reported this to the dealer. They said to bring the car back. I took the car back and diagnostic tests were run and concluded that a code was stored but it was nothing specific that had failed. Brake system was bled. In June 2011, the light cluster ("christmas tree" is how the dealer refers to it) illuminated again while I was attempting to pick up my car from my local Toyota dealer (bob smith Toyota). Again, the car was left. Again it was reported to me that the system had stored a code but no specific component was in failure and the brakes were bled. Approximately, July 20, 2011 and July 23, 2011, the lights illuminated again, only four of them (trac off, vsc, ABS, brakes). I contacted the Toyota dealer on Tuesday, July 26 and was forcing the issue on July 29, 2011 and made an appointment for August 1, 2011. On July 31, 2011, the same four lights illuminated while driving and stayed on. I stopped, turned off the engine, restarted the vehicle, and experienced a very spongy, squishy brake pedal. I contacted Toyota motor corporation to further address the concern of my vehicle now being unsafe as a result of their recall. Toyota motor corporation was vague and said that the matter could only be addressed by longo Toyota, the dealer that performed the recall, since the parts warranty would only be with them. In contacting bob smith Toyota, the service advisors swears that the problem can be resolved by them. It appears that performing the recall weakened the integrity of my brake system. As one representative said, "you will not have a catastrophic failure and you will still be able to stop. It will just take longer."

While researching another matter concerning my 2004 Toyota Highlander on your site, I read complaint #10161055 concerning a hesitation problem the owner was having and wanted to say that I have experienced the same problem. It is not constant, however it does happen frequently.

My 2004 Toyota Highlander hesitates for a couple of seconds when I accelerate from about 40 to 50 mph such as getting onto a freeway. I have never experienced this in any other vehicle. I find this hesitation to be very disconcerting and makes me worry about merging into traffic.

Excessive sulfur dioxide in 2004 V6 Toyota Highlander, there is already a tsb on the V4, but I own a V6 and have had this problem for almost a year now (stop and go and acceleration, there is a rotten-egg smell). I've been told by 2 Toyota service stations that it is the gas. This is definitely not the case. I've tried every type of gas available.
