Summary
The Toyota Sienna has 48 recalls spanning the 1998 through 2025 model years; the most serious recent issue affects 2019 models where the passenger front door can have incorrect welds that cause side and curtain airbags to either fail to deploy in a crash or fire unexpectedly without one.
On the current generation (2021-2025), third-row seatback bolts on 2021-2025 Hybrid models may not be properly tightened, allowing the seatback to fail to hold an occupant in a crash. The 2025 Hybrid adds a second seat concern: second-row seat rails with improper welds can allow the seat to shift forward in a crash. A 2024 BraunAbility wheelchair-access conversion has wheelchair tie-down anchor pucks that can work loose and detach in a crash. The 2022 model has second-row outboard seat belts with incorrect D-rings that can bunch up and tear in a crash. On 2020-2022 models, a software fault can quietly disable the electronic stability control system without the driver's knowledge. There is also a 2021 Vantage Mobility conversion where wheelchair tie-down retractors can fail to lock automatically, leaving the wheelchair unsecured.
For 2016-2019 models, a batch of 2016 vehicles received incorrect front seat belt height adjusters that can tear away from the B-pillar in a crash and leave an occupant unrestrained. The 2018 model has a wheel concern where a specific production lot of 10-spoke alloy wheels can crack at the spokes from road impact and separate from the hub. BraunAbility-converted 2017-2020 vehicles have a steering shaft extension that can fracture and cause sudden loss of steering. BraunAbility conversions from 2014-2019 also have a brake line fitting issue that can drop rear braking pressure. On 2015 models, the second-row overhead assist grips can break free during curtain airbag deployment and strike an occupant; some 2015 vehicles with dealer-installed overhead entertainment systems have a related trim clip that can fail in the same situation. The 2017 brake booster vacuum pump, shared with other Toyota models that year, can lose brake assist suddenly.
The 2011-2016 power sliding door can stall when frozen shut and then spring open unexpectedly while the vehicle is moving. The 2014 model has a fuel delivery pipe in the engine compartment that can leak near ignition sources, and a transmission shift cable whose sleeve can fray and cause the vehicle to move in an unintended direction. The 2011 front-right driveshaft can fracture without warning and cut drive power.
Going further back, 2004-2010 models registered in salt-belt states have a spare tire carrier cable that can corrode, drop the spare tire onto the road, and create a crash hazard. The shift lock assembly on 2004-2010 models allows the transmission to be moved out of Park without pressing the brake pedal, risking a rollaway. The 2004 model also has a floor carpet clip issue where a missing retention clip can jam the accelerator at nearly full throttle, a fuel tank that can rupture and leak in a frontal collision, and rear power liftgate struts that can weaken and drop the gate.
Label and compliance issues on 2011-2013 models involve incorrect tire loading information on the placard.
