I, together with my family had a car accident that happened in stamford, ct. A car struck my van perpendicularly at the left rear wheel which caused it to spun 180 degrees. As the collision occurred my seatbelt suddenly unbuckled which resulted myself slamming on the side door and incurring multiple contusion. I filed a report to Toyota motors about it, and they sent someone to look at it. According to their inspector there is no malfunction to my seatbelt. He concluded that I might had accidentally press the release button at the time of the accident. I have not touched the release button of the at the time of the accident. So far I haven't heard anything from them as of now. By the way, my van is a 2006 Toyota Sienna le AWD . I was at the right second row when the accident occurred.

Middle row and back row seat belts do not retract and get stuck. The rear belts get stuck and do not come out or retract. This is especially a problem with children as they think the seat belt is deployed properly when it is not. This happened this morning, but also happens a few times a month and seems to be getting worse.
My power door stop working on the driver back side. I had to force its close. And now I can't get it to open back up. The back row belt won't pull down. So its can't be used now. And the fuel miles on this van is very poor at 11. Toyota is very high price when its come to little problems.
The third-row center seat belt was partially extended to secure a passenger when it became locked in place. It would not retract or extend. The entire seat belt tensioner needs replaced. This device is in the roof and exposed to extreme heat when the car is parked in direct sunlight.
Problem is with the second row seat belts in my 2006 Toyota Sienna xle van. Anytime someone (myself included) rides in the second row, the seat belts lock up and become so uncomfortable as they continue to tighten that we just end up not using them soon after the trip begins. Not using them because of this defect poses a real safety hazard if we were to have an accident. Earlier on I complained several times. I was always told there is nothing wrong with them. We probably weren't using them correctly and I was even given instruction by the service department on how to hook up the seat belt. My complaints fell on deaf ears and I really do think it is a safety hazard. I told them they might have to ride it longer than the few minutes they did. I'm not so sure this problem is about my Sienna only. When I ride in the back seat of other vehicles the seat belt seems to tighten. …
To national highway traffic safety administration representatives, this e-mail is sent regarding my alert to the danger and safety concerns to citizens regarding the used car sales at Honda of fort myers, florida. Due to a "2006 Toyota Sienna" in fort myers, florida, that was sold as in very good to excellent mechanical condition and free of defects. It is been recently discovered that a major front end accident occurred on 11/16/206 in florida. The impact severity caused functionality concerns and defects to the airbags, airbag sensor, and seat belts which were never repaired properly from this accident and left damaged and defective. Sadly, the carfax history had only begun reporting this data on 10/31/2011. The owners or used car dealership neglected to disclose this facts and other severe defects, recalls, and damages that occurred to the engine. …
Last week, the airbag warning light started flashing constantly while the car is running. A quick read of the owner's manual indicates a problem with the side or curtain airbags. More research on the internet indicates that this is a common problem with siennas from 2006. This is a safety issue, and should be addressed by Toyota on a wide scale basis. My car is like new, not used much, never been in an accident and has 23000 miles. It is inexcusable for this to happen, and more inexcusable for the consumer to have to pay to fix it, considering that this appears to be a common safety issue with these cars. Please force Toyota to issue a recall, to deal with this problem fairly, for affected owners.
