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.

I just thought you should know, last year my gas pedal got stuck. I have a 2004 Toyota Highlander. When I investigated it, I found that the plastic panel to the right of the pedal had broken loose causing the panel to lift up so that the pedal could get stuck under it. The plastic screw had completely sheared off. I went to Toyota here in boulder and they replace the screw. Why manufacturers use plastic screws is beyond me. I was a little disappointed that Toyota would have used plastic screws for what is apparently a stressed area. I'm just glad I did not have an accident. It was pretty scary!

: the contact stated at various speeds, the vehicle hesitated when the accelerator pedal was depressed. Also, the vehicle shifted erratically. The dealership had reprogrammed the computer multiple times, but the problem persisted.

My 2004 Toyota Highlander exhibits a significant hesitation at the start of rapid acceleration that I believe is a potential safety hazard. When the vehicle is moving at a slow speed and the accelerator is depressed to begin a rapid acceleration (passing a slower vehicle or merging into traffic), a significant hesitation is present before the vehicle begins to accelerate. This delayed response to the accelerator input can place the vehicle in dangerous situations where the vehicle cannot get out of the way of other traffic. I believe this behavior could result in a traffic accident and potential injury to people.

Highlander 6-cyl

  • Automatic transmission
  • 2,000 miles
I purchased a new 2004 Toyota Highlander on 3/26/2004 and after about 2 months started noticing a problem with hesitation when accelerating from a stop or when passing. The car feels like it dies for 1 to 2 seconds and then lurches forward. This is very dangerous when making a left hand turn at a light with oncoming cars from the opposite direction. This also causes problems when trying to merge with highway traffic or when passing. This occures every day and when it was reported to Toyota service they stated it was a known issue with no fix or technical bulletin.
