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.

The contact owns a 2004 Toyota Sienna. The contact stated the front driver's side seat belt webbing failed to retract or properly restrain her. The vehicle was taken to a private mechanic who stated that the entire seat belt assembly needed to be replaced. The manufacturer was not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 60,000. The current mileage was 140,000.

Front passenger seat belt folds over on itself when pulled to engage. This prohibits the use of the seatbelt. Does not happen every time but probably occurs 15 to 20 times a year. When it jams if the occupant does not know how to correct the problem they ride with no seatbelt protection. Toyota washes their hands and states that it is out of warranty.

The front passenger seat belt often gets folded and jammed and does not retract. It takes a lot of messing with to get it to retract. Today, I could not get it to retract, so it is extended all the way so noone can safely sit in the front seat.

  • 50,000 miles


The front passenger seat belt has a tendency to jam whenever put on in a certain way. I have found a way to almost consistently repeat it and have found that it tends to happen with passengers of greater girth or stature. Definitely more likely to happen when the passenger pulls the seatbelt out forward towards the dashboard to put it on. What happens is the belt folds over due to the design of the pivot area and gets jammed in the gap resulting in an inoperative seatbelt. This has happened so many times that the seatbelt tension on the passenger side is now noticeably lower than the driver's side. Also reproducible on the driver's side but happens less frequently mostly due to a consistent driver. Definitely a hazard if it can't be unjammed as the seatbelt cannot be fastened or used properly. There is also a high chance of causing the belt to twist inside the pillar when trying to unjamming it thereby decreasing its strength. Have not found a way to consistently unjam it easily and usually just requires lots of manipulation.

Sienna 6-cyl

  • 98,000 miles
The front seat belts--especially the passengers seat belt, often become stuck when extended because of twisting and folding up upon itself. Sometimes the seat belt cannot retract at all; more often than not, because of the twisting, the seat belt becomes jammed in the fully extended position. The result is that the it the occupant isn't (adequately) restrained. This happens 5 - 8 times per week. Also a problem, because the belt is not retracted, it frequently gets slammed in the door when the driver or passenger get out of the vehicle. Over time, the integrity of the belt will suffer from this. I never know when the belt will twist. If a passenger leans forward and then back, that is enough for the belt to twist upon retraction. Now I have an improperly restrained passenger at risk for injury in a moving vehicle. Please do not wait for a fatality before acting on this. We require occupants to wear belts for a reason. It is the law. If Toyota's belts are failing, we lose the benefit of the seat belt and are unprotected. Please see other websites that list this problem, the VIN numbers of these cars are similar.

Both front seat belts on this vehicle fold over and bind up. They cannot be retracted properly. The front passenger side is bound so bad, it is unusable. Frustrating.

The front seat belts do not retract. I just bought this vehicle used new years eve and the first time used the seat belts jammed. I just looked on line to see if there is a fix and there are none listed, but hundreds of Siennas with this problem. This is a safety problem because I still have to use the van, but the front seat belts do not retract to tighten around passengers.

Sienna 6-cyl

  • 70,000 miles
The front seat belts (both driver and passenger side) are easily jammed and getting folded over so that the seat belt neither retracts or pulls out. It is extremely difficult to unjam the belt, and often necessitates driving without the safety of an effective seat belt. This has never happened in any other make/model car I've driven - Toyota needs to address this safety issue promptly.

Sienna 6-cyl

Numerous times the seat belt folds as it is pulled out and then jams. Prior to today I have been able to get it unfolded. Today I am not able to and now cannot drive my car safely. If I can't fix it myself I will have to drive it to the Toyota dealership without wearing the seatbelt.

The front seat belts on this vehicle jam all the time. They fold and jam with the seatbelts unable to retract and hold the driver or passenger in a safe manner. This is the only vehicle I have owned with this continuous problem.

Passenger front seat belt is twisted and will not retract and is therefore unsafe for use. Since this is a safety concern, I asked Toyota dealership if there was any recall or service bulletin issued for this problem and I was told there is nothing they are aware of. Request Toyota to investigate this concern and take prompt action in resolving this safety issue. If there is a recall / service bulletin issued or in the works, please let us know.

I own 2004 Toyota Sienna mini van. For many years, I always have a problem with the driver side seat belt. It sometimes simply does not retract. The front seat belts frequently jammed and folded and unable to retract by itself. I have Toyota dealers to check the problem in 2011 and 2012, but they are not be able to fix it. Please go to the link below, there are 33 cases reported there NHTSA should have Toyota to recall this safety defect.

On passenger side, front seat belt folds and jams as it is being pulled out to be buckled. If the belt is pulled out further, it stays jammed and does not retract, thus creating a hazard for the passenger.

  • 149,000 miles
The Sienna 2004 front seat belts are getting frequently jammed and folded and unable to fully retract. This is a problem that has been happening with alot of the Sienna owners. The belts are getting jammed, and unless you use a plier to twist to unfold to be able to get it to its retracting position. It is a driving hazard as there is alot of slack on the seat belt when the retraction is jammed. I took to dealer and said the whole seat belt system needs to be replaced. I feel this is a defect with the manufacturing and a recall needs to be made on this issue. It is happening on these vehicle after 4-5 years of use.

Seat belt twists and jams extremely easily. Extends all the way, and will not retract. Sometimes it can be manipulated to straighten it and get it to retract, but it recurs regularly. The front passenger seat is not usable when it happens. It has happened once or twice on driver's side, but occurs at least once or twice a month on passenger side.

The drivers seat belt is stuck in the extended position and will not retract. Dealership said the retraction mechanism is broken and the part costs $400. I've read about many other owners having the same problem. When will something like this be recalled. It is a real safety issue.

  • miles
The driver's seat belt continuously binds up in the re-tractor bezel. Because of this the re-tractor unit does not function properly. Some times if you do get it to come out, you can get it latched but the belt fails to tighten. In other cases it binds so badly that the side wall must be taken apart to free it.
