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.

Sienna 6-cyl

  • Automatic transmission
  • 22,000 miles


Radiator ruptured and the engine overheated; hose replaced in steering column recall; rust protective tape recall; dvd screen replaced and the entire dvd player replaced(screen still not easily visible in middle row); passenger seat belt replaced; middle passenger seat belt failing; gasoline smell inside of car with ac on recirculation; driver's window fell inside door in snow storm and was not considered a safety issue to get a loaner vehicle even though the vehicle could not be locked; tires completely bald and leaking under 30,000 miles, dvd player must be at a high db volume and when returned to radio/cd will almost deafen you; interior lights have to be manually over ridden or will drain battery; car hesitates 1-2 seconds when trying to quickly accelerate and then lurches forward alarmingly; cruise control is not functioning; waiting to have fuel mixture sensor replaced. I was not informed of first 2 recalls until I my engine overheated. I did get the rust recall and a sticker on my sliding door informing user of danger of having middle windows open while opening the middle door could catch a head or other extremity. Toyota dealer service manager says mine is the only 04 Sienna experiencing any problems except for the recalls on the radiator; the steering hose; the rust tape; and the middle seat belt. Not so according to all I have read here. Most of the problems have occurred between 22,000 and 34,000 miles; the dvd screen always failed to lock into a good position for the middle row viewers.

Seat belt gets jammed in the guides, does not retract. This is a major safety concern because when seat belt does not retract it is ussless. Dealer replaced guides but still occuring. Same issue happened in loaner Sienna. Getting passed around calling Toyota.

1. mid row passenger captains chair seat belt-shoulder harness webbing jams.. took vehicle to dealer--replaced plastic belt guide. Did not improve situation. Jammed before I left the dealership. 3. I now use strapling tape to hold guide in place. Still can have jam problems.. purchased this vehicle because of safety rating, since I Transport my grandchildren on a regular basis. Have been very disappointed with Toyota's "non response" to the problem. 5. I feel many persons are not aware of the problem since children are the usual passengers in this position & are not aware that this malfunction should be reported.

problem #1

Sienna 6-cyl

  • Automatic transmission
  • 3,000 miles
Right side second row seat belt fails every 2000 to 3000 miles. Encasement is located on the seat itself instead of the roof of the vehicle. This clip holding the encasement together pops out allowing the seat belt to catch in opening below, causing the seat belt to fail. A child or passenger could be seriously hurt. Most people won't even realize there is a problem unless they check this belt regularly as child passengers generally won't tell you when the belt doesn't not operate correctly.
