Difficulty in pulling the seats belt on the second row seats when the car is turned off. Child has no wiggle room once it’s fastened and cannot undo seat belt as there’s no room to reach to unbuckle belt. I have to force the seat belt out of booster seat so belt can retract completely. The third row seats had a similar issue but didn’t have to force to out of booster seat for it to work properly.

Relatively new Toyota Sienna, bought 6 weeks ago and currently at 1300 miles. Passenger side 2nd row seat belt inexplicably became stuck and would not retract, making that seat unusable as the seat belt was no longer able to safely restrain a passenger. No accidents or unusual incidents were noted. This was completely unexpected and random following a routine short-distance errand.

Driver side passenger 2 nd row seat belt stopped working. Won't clip as needed leaving us unable to use seat. This is a safety issue as we are not able to use the seat as needed as one is not able to strap in. This triggers the sensor and this a driving violation. Problem has been reported. Vehicle has been reported and still pending to be replaced. Unkown when issue can be resolved. Passenger seat on the second row was stuck upon purchase. Dealer made aware. they claimed a sock was stuck on railing which was not possible as issue was reported before they could schedule for vehicle to be inspected. Such sock did not exist when incident was reported. Sock was not purchased until day before taking vehicle to schedule appointment. Tension is still there but agency said it is working properly.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your
pre-purchase inspection list. Back to the
