2021 Toyota Sienna Hybrid recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-19. Recalls apply to specific VINs — run your VIN to confirm.
4 safety recalls, most serious first
1. Airbags
What's wrong, in plain English: The airbag system — the part that is supposed to protect you in a crash. A short circuit may develop in the Occupant Classification System (OCS) sensor, preventing the front passenger air bag from deploying.
What could happen: An air bag that does not deploy during a crash increases the risk of injury.
The fix: Dealers will inspect and replace the sensor as necessary, free of charge. Interim letters notifying owners of the safety risk were mailed in February 2024. Some final remedy owner letters were mailed October 31, 2024. Letters will continue to be mailed in phases through January 2026. Owners may contact Toyota custome…

I purchased my 2021 Toyota Sienna Hybrid new in March 2021. For several years I have had an intermittent braking problem: when I apply the brakes, especially while slowing down or driving downhill, the vehicle sometimes lurches or feels like it suddenly accelerates forward instead of slowing. I must press the brake pedal again to stop. This happens without…

The front passenger door lock actuator does not work properly causing the door to stay locked or unlocked despite attempts to change the door lock through the internal power locking system or remote key. This presents a safety issue in that it requires a manual lock/unlocking of the door should an emergency situation arise and expeditious ingress or egress…

The rear power liftgate hinges on my 2021 Toyota Sienna failed structurally under normal, everyday operation. The power liftgate motor and struts appear to exert uneven or excessive pressure on the rear hatch assembly, causing the metal hinges to crack.

The electronic driver's seat motor and track assembly failed completely on my 2021 Toyota Sienna (VIN: [XXX]) at less than 18,000 miles. The seat is permanently seized in a fixed position. This creates an immediate safety and crash-protection hazard, as drivers of different heights cannot safely adjust their distance from the steering wheel airbag or proper…

My liftgate has been making loud noises upon closing. The dealership checked it and diagnosed that the trunk door is mis-aligned, leaving a gap so that the door WOULD NOT SECURELY CLOSE. I was referred to the body shop to have the shocks and hinges changed. Further discussions mentioned this was a common problem with the Toyota RAV-4 where the hydraulics fa…
