What stands out
Among the 11 model years of Toyota Sienna in our records for seatbelts problems, this one ranks #3 by owner-complaint volume.
No new NHTSA seatbelts complaint has been filed on this vehicle in over 12 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering seatbelts on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners report four main seatbelt defects on the 2008 Sienna. The LATCH top tether anchor in the second row is completely covered by fabric, making it impossible to locate without disassembly. A CPST instructor confirmed this is a defect, noting owners may incorrectly attach the tether to the wrong anchor—a serious child safety issue.
Multiple owners report seatbelts that jam and lock in the retracted position, refusing to release or extend. One owner had to cut the belt to free a child it wrapped around at highway speed. Another reported the belt jammed several times before becoming permanently stuck; the dealer quoted $496 for seatbelt assembly replacement.
A second failure pattern involves belts that tighten excessively around passengers and won't loosen while latched. One owner's belt behaved this way after being replaced by a dealer; when it recurred, the dealer claimed it was normal operation. An owner also reported a driver-side belt that releases itself during every drive while simultaneously refusing to latch before driving and becoming stuck when latched.
Owners describe these as recurring problems—some vehicles had repeated jamming incidents. One owner said the issue is widely discussed online as common to the Sienna. Toyota refused to cover at least one seatbelt failure under warranty.

Failure modes owners describe
Top tether attachment point obscured by fabric
The LATCH top tether anchor in the second row is completely covered by fabric, making it inaccessible and indistinguishable from other hooks behind the seat. Owners installing car seats cannot locate the proper tether attachment point and may secure the tether to an incorrect anchor, defeating child restraint safety.
When: Present from delivery; discovered during car seat installation
Symptoms owners cite: Top tether anchor completely covered by fabric; Tether anchor indistinguishable from other hardware behind seat; Owner unable to locate correct LATCH top tether point despite consulting manual
Repairs/costs cited: Owner states CPST instructors confirmed defect and that tether bar should not be fabric-covered
Seatbelt tightens excessively and does not loosen
Seatbelts tighten around passengers and become stuck in a locked, extremely tight position. Loosening occurs only when the belt is fully unlatched. The issue recurs specifically when the seat is reclined or tilted back. Dealer replaced one belt but problem reoccurred; dealer then claimed vehicle operates as designed.
When: At 18,000 miles; recurred at 23,000 miles
Symptoms owners cite: Seatbelt becomes extremely tight around passenger; Seatbelt will not loosen while latched; Failure occurs when seat is in reclined position; Loosens only when fully unlatched
Repairs/costs cited: Rear passenger side seatbelt replaced at dealer; failure recurred
Recalls/TSBs owners mention: Dealer stated vehicle operating as designed; no further repair attempted
Seatbelt jams and locks in retracted position
Seatbelts jam, become locked, and will not release or retract. Some occurrences clear after multiple attempts; others are permanent. When jammed, the belt cannot be unlatched or extracted, making that seating position unusable. Owners report jamming occurs repeatedly on some vehicles.
When: Mileage varies; reported as early as 8,108 miles and as late as 96,000 miles
Symptoms owners cite: Seatbelt locks and will not release; Seatbelt will not retract; Jamming occurs repeatedly on affected vehicles; Belt may jam around passenger (wrapping around body); Belt folded or twisted internally
Repairs/costs cited: Seatbelt assembly replacement costs $496; belt tightening from twisting cleared only after interior panel removal and belt adjustment ($108 labor); one belt had to be cut to free a child
Seatbelt will not latch or unlatches during driving
Driver-side seatbelts release themselves repeatedly while the vehicle is in motion and refuse to latch when attempting to secure them before driving. When latched, the belt is stuck so tightly that removal is extremely difficult. Owner reports the combination of these failures makes the vehicle undriveable.
When: Recurring on each drive
Symptoms owners cite: Seatbelt releases itself during motion—happens every drive; Seatbelt will not latch when attempting to secure before driving; Seatbelt stuck in latch, extremely difficult to remove when stopped; All three issues occur together
Recalls/TSBs owners mention: Toyota case #1609160545 opened; Toyota refused to stand behind safety-related failure

At what mileage does the seatbelts typically fail?
Across the 10 complaints that reported odometer mileage, most seatbelts failures cluster between 77,000 and 130,000 miles, with the median around 96,000. A quarter of owners report trouble before 77,000; a quarter make it past 130,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $500 for seatbelts repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to seatbelts?
No active recalls currently cover seatbelts issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
