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

Sienna LE 3.3L V6

Fantasitc! Toyota informs me, that in order to get to the timing belt, they had to break $500 worth of brackets! They also claim it happens 50% of the time, so they have plenty in stock! Lucky me! It seems, due to the different metals, and being in close proximity to road spray, the brackets and bolts all bind together so they have to be sledge hammered off the engine. I contacted Toyota, who gave me a round of circle logic, telling me that if I didn't want to pay for parts, I should have had the timing belt done in warranty (before 100000kms). What? Why would you change the belt 44000 kms before the maintenance schedule calls for it? Unbelievable. This along with all the other problems this van should not have had, and I've sealed my Toyota buying future.
