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

problem #1

Sienna XLE Limited 3.3L V6

  • Automatic transmission

I had this rattling engine noise upon startup for about 3 years already. Read a lot about the same concerns on Toyota Sienna forums saying that it was an oil sludge issue with the engine design or a vvti issue, etc. Brought my van to a Toyota dealer (where I bought it brand new) and was informed I have to pay for them to check on the problem. Decided to get opinion from other car shops and unfortunately getting different information. I tried using some oil additives to no avail. I am almost giving up and just have to deal with the startup noise hoping nothing more serious happens to the engine.
