AIR BAGS
Owners report issues related to a recall for the air bags in the 2021 Toyota Sienna Hybrid, specifically mentioning that the parts required for the recall repair are not available. Complaints frequently mention that the manufacturer has exceeded a reasonable amount of time to provide the necessary parts for the repair. In these reports, no actual air bag failures are described, and there are no mentions of crashes, fires, or loss of control. One owner notes that the SRS warning light is illuminated, but no other symptoms are reported. This information may be useful for potential buyers to understand the current status of recall repairs and the availability of parts.
Owner complaints3
VISIBILITY/WIPER
Owners of the 2021 Toyota Sienna frequently report a visibility issue related to the rear entertainment system. When the entertainment screen is in use, it obstructs the view through the rearview mirror, which owners describe as a significant safety concern. This issue is noted in vehicles equipped with the rear entertainment package, particularly in the XLE trim level, and is often identified shortly after purchase, within the first few weeks of ownership. Owners express concern about the inability to see vehicles approaching from behind, especially at stop signs, and suggest that a digital rearview mirror could mitigate this problem. There are no reports of crashes or loss of control, but the visibility obstruction is consistently highlighted as a safety risk.
Owner complaints2
SEATS
Owners report two main issues with the seats in the 2021 Toyota Sienna Hybrid. Some describe melted spots on the lower back rest of both the driver’s and front passenger’s seats, typically observed when the vehicle is parked, with one case occurring around 60,000 miles. Others mention an abnormal rattling sound from the second-row seats while driving, accompanied by a "Check Rear Seats" message, with this issue noted at approximately 169,000 miles. Safety implications are not directly reported, as there are no mentions of crashes or fires related to these seat issues. This information may be useful for used car buyers considering potential seat-related concerns in this model.
Owner complaints2
STRUCTURE
Owners of the 2021 Toyota Sienna Hybrid report issues related to the vehicle's structure, specifically involving water intrusion and rear liftgate malfunctions. Complaints frequently mention an abnormal splashing noise inside the vehicle, attributed to water inside the doors, with one owner noting this issue at approximately 22,500 miles. Additionally, another owner describes a malfunctioning rear liftgate that fails to open, which required manual intervention to resolve, occurring at around 67,000 miles. These issues do not indicate crashes or safety incidents, but potential buyers should be aware of these structural concerns, particularly regarding water intrusion and liftgate reliability.
Owner complaints2
EXTERIOR LIGHTING
Owners report two distinct issues with the 2021 Toyota Sienna's exterior lighting. The first involves the third brake light, where complaints frequently mention poor visibility due to reflections off the rear window and defrost elements, particularly in low or dark lighting conditions. This reflection limits the operator's rear visibility, potentially impacting safe driving. The second issue, although primarily related to the interior, involves climate controls falling from the headliner and injuring rear passengers, which occurs at any speed. While these complaints do not specify mileage ranges, the safety implications include limited rear visibility and potential passenger injury.

SEATSNHTSA 25V086000Feb 13, 2025
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2021-2025 Sienna Hybrid vehicles. The bolts for the seatbacks on the third-row seat assemblies may not be tightened properly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 202, "Head Restraints," 207, "Seating Systems," and 225, "Child Restraint Anchorage Systems."
Consequence: An improperly tightened seatback may not adequately restrain the occupant during a crash, increasing their risk of injury.
Remedy
Dealers will tighten the seat assembly bolts, free of charge. Owner notification letters were mailed April 1, 2025. Owners may contact Toyota's customer service at 1-800-331-4331. Toyota's number for this recall is 25TA05.
AIR BAGSNHTSA 23V865000Dec 20, 2023
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Avalon, Avalon Hybrid, Corolla, Highlander, Highlander Hybrid, RAV4, RAV4 Hybrid, Lexus ES350, Lexus RX350, Lexus RX450H, 2021 Sienna Hybrid, Lexus ES250, 2020-2022 Camry, Camry Hybrid, and ES300H vehicles. A short circuit may develop in the Occupant Classification System (OCS) sensor, preventing the front passenger air bag from deploying.
Consequence: An air bag that does not deploy during a crash increases the risk of injury.
Remedy
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 customer service at 1-800-331-4331. Toyota's number for this recall is 23TB15/23TA15 Lexus 23LB03/23LA03.

Listing benchmarks establish a market range; trim, mileage, condition, title history and prior damage determine what one vehicle is worth.
The 2021 Toyota Sienna posts an above-segment reliability score, indicating solid overall dependability relative to peers. With a limited recall count, the data points to a generally controlled risk profile rather than widespread systemic problems.
Complaint activity is not evenly spread across the vehicle. Reports cluster heavily around air-bag-related concerns, while the remaining issues appear in smaller pockets involving visibility/wiper performance, seats, structure, and exterior lighting. That concentration suggests the ownership risk is more about a specific system than a broad pattern across major vehicle functions. As the first year of a new generation, the data still reads as above average.
Overall, risk level is moderate-to-low, with attention centered on a single dominant category.
