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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2004 Toyota Sienna Owner Comments

We've are the original owners of the 2004 Toyota Sienna XLE Limited Van (132,000 miles). We have had the VSC Traction Control System malfunction numerous times since November 2015. While driving the van at any speeds...the Traction Control goes on on its own which applies the brakes, makes the van lunge to the right and the lights on the dash board come on with annoying beeps. We have taken the 2004 Sienna into our local Lithia Toyota dealer over the last 9 month over 3 separate times to no avail. They have checked out the VSC system and says "Computer is working fine". During test drives with the dealer, they couldn't duplicate the malfunction. After picking up the van in June 28, 2016 from Lithia Toyota of Redding, we didn't get 3 miles down the highway when the VSC Traction Control System automatically came on during normal 45 m.p.h. on a slight curve. Thus, endangering myself, wife and two children. Called the dealer right back and reported the problem and was told nothing is wrong with the van! When the VSC system is about to come on we notice an acceleration problem. No matter how much you are pressing the accelerator the van doesn't engage in going faster, then the bells, lights and traction control goes off and puts on the brakes automatically and veers you to the right. This VSC Traction Control System is currently still an issue. Happens at least once a day if not more. We have avoided several accidents thus far, but Sienna Van is going to cause an accident or harm if the problem isn't identified and repaired by Toyota.
