For families who bought a Toyota Sienna partly for its passenger space, a new Canadian recall creates an unusually disruptive safety problem. Toyota is advising owners of 24,454 recalled Sienna Hybrid minivans not to carry anyone in the second-row seats until repairs are completed.
The recall covers certain 2022 through 2026 model-year vehicles. Transport Canada says the mechanisms that lock the second-row seat recliners can, under certain conditions, disengage when a seat-belt pretensioner activates. If that happens during a crash, the seatback could move and increase the risk of injury. The prescribed repair is an update to software in the supplemental restraint system electronic control unit, rather than the seat-rail replacement involved in a separate Sienna recall announced in 2025.
Why Toyota Is Telling Families to Leave the Second Row Empty
Transport Canada lists 24,454 Sienna Hybrids in Canada under recall 2026-505, covering model years 2022, 2023, 2024, 2025 and 2026. The department categorizes the issue under seats and restraints and says the second-row recliner locking mechanisms may disengage when a seat-belt pretensioner activates. A seatback that does not remain where it is supposed to during a collision can change how effectively the occupant is restrained.
The most important part of the federal notice is therefore not simply the existence of a recall. It is Toyota’s interim instruction. Owners are being advised not to use the second-row seats to transport passengers until the recall repair has been completed. For a household that routinely puts children, grandparents or other passengers in the middle row, that changes the vehicle’s practical carrying capacity immediately. It also means that merely waiting for a recall letter while continuing to use every seating position would be inconsistent with the safety guidance currently published by Transport Canada.
What Can Go Wrong During a Crash
Modern occupant-protection systems depend on several components working together at the instant of a collision. Transport Canada notes that seat belts in passenger vehicles can incorporate devices such as pretensioners and load limiters and that these systems work with airbags during frontal crashes to reduce the risk of occupants striking parts of the vehicle interior. In the recalled Siennas, the concern involves an unexpected interaction between pretensioner activation and the second-row seatback recliner mechanism.
The federal recall does not suggest that every second-row seatback will suddenly release during everyday driving. Instead, it describes a problem arising under certain conditions when the pretensioner activates. The danger is that a system intended to help restrain an occupant could coincide with the recliner mechanism becoming unlocked, allowing the seatback to move during the crash. That is why the potential consequence matters even though the triggering circumstances are specific. Vehicle seats, belts, anchorages and airbags form a coordinated restraint system; unwanted seatback movement can undermine the position in which that system was designed to protect an occupant.
Why the Warning Hits Sienna Families Especially Hard
Toyota markets the Sienna as a people-mover, and its Canadian configurations underline how central the second row is to the vehicle’s purpose. The 2026 Sienna is offered in seven- and eight-passenger forms. Eight-seat versions use a second-row bench arrangement, while several seven-seat versions use a pair of captain’s chairs. Higher trims can include long-slide captain’s chairs, heated second-row seating and ottomans, making the middle row one of the van’s defining passenger spaces.
That makes this recall different in everyday impact from a defect involving a feature owners rarely use. A family may have selected a Sienna specifically because it could carry several children and adults without requiring a second vehicle. Removing the second row from passenger duty can turn school runs, carpools, weekend outings and multigenerational trips into logistical problems. Toyota even equips the 2026 Sienna with an advanced rear-seat reminder designed to detect people in the second and third rows. The irony is difficult to miss: one of the vehicle’s most family-oriented spaces is temporarily the area Toyota says affected owners should leave unoccupied.
Which Siennas Are Covered and How Owners Can Check
The Canadian recall applies to Sienna Hybrid vehicles from the 2022 through 2026 model years, but owners should use the vehicle identification number rather than the model year alone to determine whether a specific minivan is included. Transport Canada’s recall database links owners directly to Toyota’s recall-checking service, and Toyota Canada’s own site provides a VIN-based lookup for safety recalls and service campaigns.
A VIN is the unique 17-character identifier assigned to a vehicle. Toyota says it can be found on vehicle registration or insurance documents, on the driver’s side of the dashboard near the windshield, and on the information label at the driver’s door pillar. Toyota also says owners and lessees are normally notified by mail when their vehicle requires recall-related work. Checking electronically can still be worthwhile instead of waiting for the envelope to arrive, particularly for recently purchased used vehicles or vehicles whose registration or owner contact information may have changed. Transport Canada identifies Toyota’s Canadian customer contact number for this recall as 1-888-869-6828.
The Planned Repair Focuses on the SRS Control Software
The current Canadian remedy is notable because Transport Canada does not call for replacement of the second-row recliners themselves. Instead, Toyota will instruct affected owners to bring their Siennas to a dealership so technicians can update the software in the supplemental restraint system, or SRS, electronic control unit. That unit controls the pretensioners involved in the recall condition.
In other words, the Canadian notice currently describes a software-based correction to the way the restraint system operates rather than a mechanical rebuild of the second-row seat. Toyota Canada states generally that inspection or repair required under a Safety Recall Campaign is performed at no charge to the vehicle owner. The federal Sienna notice does not specify how long this particular software procedure will take, so owners should not assume a service duration before speaking with a dealer. More importantly, the relative simplicity of a software remedy does not change Toyota’s interim safety instruction. Until an affected vehicle has actually received the recall repair, the second-row passenger restriction remains the guidance published by Transport Canada.
This Recall Is Different From the 2025 Second-Row Rail Problem
Some Sienna owners may remember another warning about leaving the second row empty, but that earlier campaign involved a different defect. In October 2025, Toyota announced a Canadian recall involving approximately 7,142 model-year 2025 Siennas because their second-row seats could have been mounted on seat rails that were improperly welded. Toyota warned that a seat could lose structural integrity in certain high-speed collisions, increasing the risk of injury.
The remedy for that campaign was mechanical: dealers were to replace the affected second-row seat rails with properly welded components at no charge. The new 24,454-vehicle recall concerns the recliner locking mechanism and its interaction with pretensioner activation, with Transport Canada currently calling for an SRS control-unit software update. Distinguishing the recalls matters because a 2025 Sienna could potentially appear in owners’ searches alongside more than one campaign, while other vehicles may be covered only by the newer issue. A completed repair for the older rail recall should therefore not be assumed to resolve the newly announced recliner-related recall.
Sienna Has Also Had a Separate Third-Row Seat Recall
The Sienna has faced another recent Canadian seat-related campaign involving a different part of the cabin. In February 2025, Toyota recalled approximately 17,684 Siennas from the 2021 through 2025 model years because bolts connecting the split 60/40 third-row seatbacks to their recliner assemblies might not have been tightened to specification. Toyota said a seatback in that condition might not perform as intended during a crash, increasing the risk of injury.
Dealers were instructed to tighten the affected third-row seat bolts to the proper specification at no charge. That campaign should not be conflated with either the improperly welded second-row rails announced later in 2025 or the new second-row recliner issue affecting 24,454 vehicles. Together, however, the separate campaigns make a VIN search particularly valuable for Sienna owners. Rather than assuming that a vehicle has one recall because of its model year, an owner can determine which specific campaigns remain open. That is especially relevant for used Siennas, where a previous owner may have completed one recall but not another.
What Parents Should Do About Child Seats and Passenger Seating
The second-row warning is particularly consequential for families using rear-facing seats, forward-facing child restraints or booster seats. Transport Canada’s recall notice says affected owners should not use the second row to transport passengers until repairs are completed; it does not provide an exception for a child riding in a car seat. Families should therefore avoid treating a properly installed child restraint as a workaround for a seating position Toyota has advised owners not to use.
If another rear seating position is being considered, Transport Canada’s general child-restraint guidance says caregivers should read both the vehicle owner’s manual and the child-seat manufacturer’s instructions and follow the applicable provincial or territorial rules. A restraint should only be moved to another seating position when it can be installed and used correctly there. Transport Canada has specifically advised that, if an infant seat cannot be installed correctly in a vehicle, another vehicle should be used for transporting the infant. Sienna owners should also check their VIN for any additional open campaigns before assuming another seating row is unaffected by an older recall applicable to their individual vehicle.
What Owners Should Do Next
The most practical first step is to run the Sienna’s 17-character VIN through Toyota Canada’s recall lookup rather than relying solely on the broad 2022–2026 model-year range. If the vehicle is included, owners should contact a Toyota dealer about the repair and follow the instruction not to carry passengers in the second row until the recall work has been completed. Owners whose contact information has changed should also update it so future manufacturer notices reach the correct household.
Toyota says safety-recall work is performed without charge to the owner. For questions, Toyota Canada’s Customer Assistance Centre lists 1-888-869-6828, while Transport Canada’s recall database carries the same contact number for campaign 2026-505. Families facing an immediate transportation problem can also ask their dealership what options, if any, are available while arranging the repair, rather than assuming a particular accommodation is guaranteed. The key distinction is simple: a recall letter may be administrative, but the recommendation to keep passengers out of the affected second-row seats is active safety guidance until the repair is completed.
