Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The rear most driver side seat belt was severely damaged by a steel bracket that holds the center seat/ middle seat on the 8 passenger model. This bracket is located behind the plastic covers. The steel bracket is razor sharp. The seat belt was severely cut. We can send pictures. The seat belt has been replaced by us. But other owners need to be made aware of this design flaw. Thanks.”
NHTSA complaint #11205423, filed 2019-05, 75,000 miles“Shoulder straps of passenger mid-section seats have lost tension and do not reliably retract, possibly due to extended car seat installation (britax pinnacle clicktight, was installed for prolonged period in harness mode). Lack of shoulder strap tension is a severe hazard as I attempted to convert britax pinnacle clicktight to booster mode but found that child could loosen their shoulder strap and be sitting in booster mode seat with a loose shoulder strap that is not holding them tight and secure at the shoulder.”
NHTSA complaint #10990496, filed 2017-05, 33,599 miles“2nd row seat belts bind and generally do not retract, even when seat is occupied. They remain loose and flop around and do not snug up against the occupant as every other seat belt does. Dealer says all the Sienna's do that because it's such a long belt - in fact he replaced the belt and the replacement does the same thing. This seems like a safety hazard since in the case of a wreck I worry that the seat belt may not retract correctly to restrain the occupant, or even if it retracts it may not be positioned correctly. …”
NHTSA complaint #10927597, filed 2016-11, 8,000 miles“Passenger side middle row seat belt has locked up fully retracted. Dealership service center stated on invoice, “nothing found to be causing the binding other than a mechanical issue, quoted replacing the seat belt assembly.””
NHTSA complaint #11623175, filed 2024-11“Seat belt will not retract. No accident/collission. It seems the seat belt is defected and dealer refuses to correct, stating seat belt is out of warranty. My child pulled the seat belt to put it on and it just simply did not retract.”
