ANALYSISHow safe is the 2021 Toyota Sienna?

The 2021 Toyota Sienna earns an 88/100 Safety Index, placing it in the Strong band. This is the first model year for the re-engineered Sienna, now sold exclusively as a hybrid AWD platform, and it maintains the same Safety Index score as the 2020 model. The Sienna received a 5-star overall rating. Within the crash protection sub-score, which stands at 61 out of 70, the Sienna received a 5-star rating for side impact. Frontal crash tests resulted in a 4-star rating, as did the rollover resistance assessment. The avoidance technology sub-score achieved a maximum 10 out of 10, reflecting standard inclusion of forward collision warning, lane departure warning, and electronic stability control. The vehicle's defect record sub-score of 16.75 out of 20 is based on two recalls. One recall, issued in 2025, addresses third-party mobility equipment. The second recall, from 2022, involves an electronic stability control software update. Neither recall relates to a structural or powertrain failure mode that would broadly impact the fleet or necessitate a do-not-drive directive. Owner complaints total 33, with allegations concerning the air bags being the most frequent, a detail to note for future assessments.

USED BUYERWhat should used buyers know about the 2021 Toyota Sienna?

Potential purchasers of a 2021 Toyota Sienna must verify the status of two open recall campaigns. The electronic stability control software update and the mobility wheelchair restraint repair both warrant confirmation through a Toyota dealer, using the vehicle's VIN, prior to purchase.

  • The 2021 model year is the first Sienna sold exclusively as a hybrid AWD configuration, and NHTSA still awarded it a 5-star overall crash rating in that new form.
  • An ESC control module software recall issued in 2022 covers this specific model year and should be verified as completed via VIN lookup before purchase.
  • A 2025-issued recall targets wheelchair restraint latch and anchor hardware on mobility-converted units of the 2021 Sienna, making this check especially important for any van with aftermarket accessibility equipment.
  • Air bags account for 12 of the 33 unverified NHTSA complaints filed against this model year, the single largest complaint category and worth discussing with a dealer during any pre-purchase inspection.
