The airbag light comes on and stays on when the vehicle is turned on. If the vehicle is turned off then back on, sometimes the light turns off. Other times, moving the connectors under the front seats causes it to turn off. *tr

What stands out
Owners have filed 35 airbags complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA airbags complaint has been filed on this vehicle in over 12 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2007 Sienna has a documented wiring and sensor issue in the airbag system that can trigger false warning lights or—more critically—disable airbags entirely, leaving you unprotected in a crash. Repair costs run $300–$4,000 and are not covered after warranty; several owners report crashes where airbags failed to deploy.
The 2007 Sienna has a widespread problem with its airbag warning system. Owners report the dashboard airbag light blinking on and off intermittently or staying illuminated, often clearing when the ignition is cycled or connectors under the seats are moved. When taken to dealerships, the light frequently stops flashing during diagnosis, making the problem hard to confirm. Diagnostic codes B0111 and B0116 point to passenger-side airbag sensor or wiring harness faults.
The real concern: owners who drove with an illuminated or flashing airbag light were operating with disabled airbags, unaware of the risk. Five separate crash incidents resulted in complete airbag non-deployment at impact speeds of 35–45 mph and higher. Vehicles were destroyed and occupants sustained injuries to the head, neck, and back.
Root causes include loose or corroded wiring connectors under the driver and passenger seats and failing airbag sensors. Toyota has issued TSBs (Technical Service Bulletins) addressing these issues on 2004–2008 Siennas with updated connectors and harnesses. However, repairs fall outside warranty coverage after 60,000 miles or five years, costing owners $337–$4,000 depending on what fails. Multiple owners discovered the problem only at high mileage and refused repairs due to cost, choosing to drive without functional airbag protection rather than pay out of pocket for a safety system.

Failure modes owners describe
Intermittent airbag warning light (SRS/airbag indicator)
Dashboard airbag warning light blinks on and off intermittently or stays illuminated, often clearing temporarily then returning. Owners report the light cycles unpredictably over weeks or months. When taken to dealers, the light frequently does not illuminate during diagnosis, making troubleshooting difficult.
When: Occurs at any mileage; owners report onset between 49,000 and 137,000 miles. One owner noted it began at 59,000 miles and persisted for a year.
Symptoms owners cite: Airbag warning light flashing or illuminated on dashboard; Light cycles on and off intermittently; Light disappears when ignition is cycled; Moving connectors under front seats temporarily turns light off; Light difficult to reproduce at dealership
Codes mentioned: B0111, B0116, P0116
Repairs/costs cited: Dealers quote $337–$4,000 depending on diagnosed cause. Repairs include: passenger side front seat airbag sensor replacement ($700); airbag assembly replacement (~$900); wiring harness and connectors under driver or passenger seat ($337–$1,100); complete restraint system rewiring ($4,000). One owner reports TSB repair for updated airbag connectors and pig-tail harness cost $337.39.
Recalls/TSBs owners mention: Toyota TSB T-SB-0252-08 and TSB 0162-10 (dated 02/27/2008) address airbag connector and harness failures on 2004–2008 Sienna. Some owners note a recall notice was sent but others state no formal recall has been issued. Owners report Toyota acknowledges problem but repairs are not covered under warranty after 60,000 miles or 5 years.
Airbags failed to deploy in crashes
In five separate crash incidents, airbags did not deploy despite impact severity that should have triggered deployment. Crashes include rear-end collisions at high speed, side-impact collisions, and frontal impact at 35–45 mph. Owners report vehicles were totaled or destroyed. Connection to illuminated/flashing airbag warning light noted in at least two cases.
When: Failures reported at mileages of 100,000–149,000 miles. One owner was involved in a non-deployment crash in 2009 while also experiencing intermittent airbag light.
Symptoms owners cite: No airbag deployment in rear-end collision at high speed (estimated 40+ mph); No airbag deployment in side-impact collision; No airbag deployment in frontal impact at 35–45 mph; Vehicle destroyed or totaled; Occupant injuries (head, neck, shoulder, back pain reported in separate incidents); Airbag warning light was illuminated or flashing prior to or at time of crash in some cases
Codes mentioned: B0111
Repairs/costs cited: Vehicles were not repaired; all were deemed destroyed or totaled. One incident involved vehicle catching fire post-crash. No owner indicated repair of airbag system prior to failure.
Recalls/TSBs owners mention: Manufacturer was notified in three of five cases; in two cases notification status unclear or stated manufacturer not contacted. No recalls or remedies mentioned by owners.
Loose or corroded wiring connectors under seats
Multiple owners report loose or poorly connected wiring under the front driver and passenger seats, identified as the root cause of intermittent airbag warning lights. Owners note moving or adjusting connectors temporarily resolves the light. One owner specifically identifies yellow connector under passenger seat as problem. Wires described as having bad connections.
When: Reported at mileages ranging from 59,000 to 90,000+ miles.
Symptoms owners cite: Airbag warning light illuminates or flashes; Moving connectors under front seats temporarily clears the light; Poor or corroded wire connections visible; Problem intermittent and unpredictable
Repairs/costs cited: No specific repair costs stated for connector-only repairs. TSB-referenced repairs include replacement of updated connectors and pig-tail harness ($337.39 in one case). Some owners chose not to repair due to cost or concern about recurrence.
Recalls/TSBs owners mention: Toyota TSB 0162-10 addresses connector and harness issues on 2004–2008 Siennas and includes updated parts. Owners report Toyota knows about the problem and references TSB, but repairs not covered under standard warranty.

At what mileage does the airbags typically fail?
Across the 28 complaints that reported odometer mileage, most airbags failures cluster between 66,000 and 105,000 miles, with the median around 88,770. A quarter of owners report trouble before 66,000; a quarter make it past 105,000. 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 $1,100 for airbags 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 airbags?
No active recalls currently cover airbags 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.
