What stands out
Airbags accounts for 32% of every owner complaint on file for this vehicle — the dominant problem area across 12 categories tracked.
Owners have filed 195 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.
The failure pattern owners describe
Buyer takeaway: A 2011 Sienna with a Takata airbag recall history is a serious safety concern — Takata inflators can rupture in hot/humid climates (Zone A), ejecting metal shards. Multiple owners also reported airbag non-deployment in moderate-speed crashes. Verify that the airbag recall has been completed with genuine replacement parts and get a pre-purchase inspection focusing on airbag and electrical systems; extended wait times and parts shortages plagued these repairs for years.
The 2011 Toyota Sienna is plagued by Takata front passenger airbag inflators that degrade in high-heat, high-humidity environments (designated Zone A climates). The propellant can rupture during deployment, potentially ejecting metal fragments that strike occupants and cause serious injury or death. Toyota issued recall notices in mid-2016 instructing owners not to occupy the front passenger seat — a severe practical burden for a seven-passenger family van.
The repair catastrophe compounded the safety hazard. Parts were unavailable for 8–11+ months after the recall was issued, leaving owners unable to use their vehicles as designed. Dealers offered inadequate loaner vehicles (compact cars instead of comparable minivans). Toyota representatives verbally suggested passenger use was safe but refused to confirm it in writing. When owners demanded repairs, Toyota either refused to help or offered unacceptable workarounds. One owner spent over $17,000 on rental costs while waiting for a part.
Separate reports document airbag non-deployment during moderate-speed collisions (30–38 mph), leaving occupants unprotected. Owners also reported power sliding door failures requiring motor and control button replacement, again delayed by parts shortages. One owner reported unintended acceleration into a building without airbag deployment. Toyota has largely dismissed these incidents as not defective and denied liability.

Failure modes owners describe
Takata front passenger airbag inflator degradation — propellant rupture hazard
Takata-supplied front passenger airbag inflators are subject to propellant degradation after prolonged exposure to high heat and humidity, particularly in Zone A climates (high heat/humidity areas). Degraded propellant can cause the inflator to rupture during deployment, potentially ejecting metal fragments through the airbag cushion material and striking occupants, causing serious injury or death. Owners in affected vehicles (primarily 2011 Sienna) were instructed not to allow anyone to sit in the front passenger seat until the remedy became available.
When: Recall issued mid-2016 (June–July 2016); vehicles manufactured ~2011; failure risk increases with age and environmental exposure
Symptoms owners cite: Recall notice received instructing owners not to occupy front passenger seat; No airbag deployment during front-end and passenger-side impacts despite significant collision forces (30–38 mph, passenger-side T-bone crashes); Airbag warning indicator illuminating when armrests touched (symptom of electrical/sensor disconnect related to recall conditions)
Codes mentioned: NHTSA Campaign 16V340000
Repairs/costs cited: Remedy consists of replacement of airbag inflator or entire airbag assembly. Parts unavailable for extended periods (8–11+ months reported); owners cite wait times of 4–6+ weeks even after parts allegedly became available in late 2016/2017. One owner reported $17,000+ in rental costs while waiting for repair. Loaner vehicles offered were often too small for family use (compact cars/5-passenger Camry offered instead of comparable 7-passenger replacement).
Recalls/TSBs owners mention: Toyota issued recall notices (NHTSA 16V340000) in June–July 2016 designating some vehicles as Zone A (highest risk). Toyota offered loaner vehicles (often inadequate), provided case/file numbers but gave no ETAs for parts or repairs. Toyota representatives allegedly suggested informally that passenger use was safe but refused to confirm in writing. When confronted after extended delays, Toyota refused to address the problem or provide compensation. Some dealers disassembled power sliding doors as a workaround while awaiting parts.
Airbag non-deployment during moderate to high-speed collisions
Multiple owners reported that airbags failed to deploy during moderate to high-speed collisions involving frontal, passenger-side, and side-impact forces. In some cases, vehicles were involved in crashes with speeds documented at 30–38 mph; in one instance, crash data showed a vehicle hit another at 38 mph. Despite these impact forces, no airbag activation occurred, leaving occupants unprotected.
When: Incidents reported 2014–2016 in vehicles with 27,000–120,000 miles; one case at ~40,000 miles involved unintended acceleration and building impact without deployment
Symptoms owners cite: Complete absence of airbag deployment on frontal impact (38 mph rear-end collision, driver struck building following unintended acceleration); Failure of side curtain airbags to deploy on passenger-side T-bone crashes (30–35 mph); No airbag deployment on rear-end impact at stop sign (accident speed unknown but impact sufficient to cause injuries); Vehicle tilted on side, dragged over 100 feet after side-impact; no airbag inflation despite significant crash forces
Codes mentioned: NHTSA Campaign 16V340000, Crash Data Recorder data available in one case (38 mph impact recorded)
Repairs/costs cited: Crash data recorder downloaded in one case showing 38 mph impact; Toyota provided no explanation of the data or airbag failure. One owner paid ~$9,000 for repair of extensive damage (rear-end collision at 38 mph). Vehicles were not diagnosed or repaired in some cases; insurance lots held vehicles; independent body shops involved in damage assessment.
Recalls/TSBs owners mention: Toyota conducted third-party investigations and reviewed crash data recorder information in at least one case but concluded the airbag was not faulty and that injuries from such impacts are not proven to be preventable by airbags. Toyota denied liability and refused to provide analysis of crash data to owners. No TSBs or recalls issued for this failure mode; manufacturer stated this is not a defect.
Power sliding door failures — door malfunction and control system issues
Owners reported power sliding door failures including doors that failed to open, opened inadvertently, or became difficult to operate manually. Underlying causes include failure of the sliding door motor and control button that regulates door operation. Doors were replaced but the root cause (electrical/mechanical) was difficult to diagnose across multiple dealers.
When: Recalls issued ~November 2016 (NHTSA 16V858000); failures reported at ~65,000 miles; repairs attempted through mid-2017
Symptoms owners cite: Driver and passenger side sliding doors failed to open; Doors opened inadvertently without user input; Doors became very difficult or impossible to operate manually; Control button malfunction preventing normal power operation
Codes mentioned: NHTSA Campaign 16V858000
Repairs/costs cited: Diagnosis required testing at three different dealers before root cause identified; ultimately, sliding door motor and control button were replaced. Parts unavailable for extended periods; owners offered workaround of disabling power feature and operating doors manually (unacceptable for families and elderly users). Repairs completed for some; status unclear for others.
Recalls/TSBs owners mention: Toyota issued recall NHTSA 16V858000 for power sliding door issues on certain 2011–2016 Siennas. Parts shortages delayed repairs. Manufacturer advised owners to disable power feature and operate doors manually pending parts availability. No specific ETA provided.
Unintended acceleration — vehicle accelerated despite brake pedal engaged
Owner reported that the vehicle unintentionally accelerated as the brake pedal was depressed and failed to respond, causing the driver to lose control and crash into a building. No airbag deployment occurred during this impact.
When: Incident at ~40,000 miles; no year given but vehicle is 2011 model
Symptoms owners cite: Vehicle accelerated without driver input despite brake pedal depressed; Brake pedal failed to respond; Uncontrolled acceleration into a building; No airbag deployment on impact with building
Repairs/costs cited: Vehicle towed to independent mechanic for repair; extent of repairs not specified. No diagnostic work documented.
Recalls/TSBs owners mention: Manufacturer was not made aware of the failure; no investigation or response documented.
