Seat Belt Assembly Defect (8-Passenger Models)
Certain 2022 Sienna vehicles equipped with seating for eight passengers may have an incorrect seat belt webbing guide installed on the outboard second-row seat belt assemblies. The incorrect guide can reduce the effectiveness of the seat belt in a crash.
Toyota issued a recall to replace the outboard second-row seat belt assemblies free of charge. Owner notification letters were mailed January 10, 2022. Check your VIN at Toyota.com/recall.
Est. Cost: Covered under recall12V Battery Drain from Kick Sensor (Cold Weather)
Some 2022 Sienna Hybrid vehicles equipped with a kick sensor (hands-free power sliding doors or liftgate) may experience a depleted 12V battery. The kick sensor draws excessive current in cold weather, draining the battery overnight and preventing the vehicle from starting.
Toyota issued a TSB to update the kick sensor ECU software that corrects the abnormal current draw in cold temperatures. The dealer reprograms the module. If the 12V battery has been deeply discharged, it may also need replacement.
Est. Cost: $0 for software update; $200 - $350 for battery replacement if neededHybrid Braking Transition Lurch
The Sienna's hybrid system can cause a noticeable lurch or surge when braking at low speeds, particularly when transitioning from regenerative braking to friction braking. The vehicle may feel like it pushes forward momentarily when coming to a complete stop.
A Hybrid Control ECU software update from the dealer can smooth the regenerative-to-friction braking transition. This is a known characteristic of Toyota hybrid systems that has been improved through multiple software calibrations.
Est. Cost: $0 under warrantyFuel Gauge Inaccuracy on Inclines
Some 2021-2022 Sienna Hybrid vehicles display inaccurate fuel gauge readings when the vehicle is driven up or down an incline and left parked at an angle of up to 15 degrees for five minutes or longer. The gauge may show significantly more or less fuel than actual.
Toyota issued a TSB acknowledging this behavior and released a software update to improve the fuel level reading algorithm when the vehicle is parked on an incline. The meter ECU is reprogrammed at the dealer.
Est. Cost: $0 under warrantyVehicle Stability Control (VSC) Software Defect
The Skid Control ECU software may not re-enable the Vehicle Stability Control system when the vehicle is restarted after the driver previously disabled VSC. This leaves the stability control off without driver awareness.
Toyota issued recall 22TA03 to update the Skid Control ECU software. Dealers perform the free software update. Owner notification letters were mailed May 27, 2022.
