This service and repair manual is written for the 2022 Toyota Sienna, the year Toyota sold the van as a hybrid only. Every 2022 Sienna carries the same powertrain, the 2.5L four-cylinder (A25A-FXS) paired with Toyota's hybrid system, so the torque values, service intervals and diagnostic steps here are the ones Toyota specifies for that exact combination rather than figures shared across a range of drivetrains.

Known issues on the 2022 Sienna. Three recalls are on federal record for this model year. One is a software recall on the electronic stability control module: driving with a deactivated stability control system increases the risk of a crash. A second covers rear seat belt anchorage on Siennas built with seating for eight passengers, where an incorrect seat belt webbing guide may have been installed; during seat belt pre-tensioner deployment, the incorrect webbing guide may damage the seat belt. The third is an equipment recall from Vantage Mobility covering QRT-Deluxe and QRT-Max wheelchair restraints fitted to certain Siennas, where an unsecured wheelchair can move during transit, increasing the risk of injury. No owner complaints are logged for the year, and Toyota has issued 83 technical service bulletins.
Whether you are chasing a stability control fault, checking a rear belt anchorage on an eight-passenger van, or servicing the hybrid powertrain, the procedure and the specification you work to are Toyota's own for this 2022 Sienna.
