NHTSA's VIN data lists these trims for the 2023 Sienna. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 70 complaints with NHTSA about the 2023 Sienna. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

What the columns count
Complaints: complaints that name that part. One complaint can name several parts, so the rows overlap and don't add up to the total.
Crashes and Fires: complaints that report one. Two owners can file about the same event, and NHTSA doesn't link them, so these count reports, not events.
Injuries: the number of people the complaints say were injured.
None of these columns shows that a part caused a crash, fire or injury: they're what owners reported, unverified.
Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 2 recall campaigns for the 2023 Sienna over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.

Vantage Mobility, LLC (VM) is recalling certain 2021-2026 Honda Odyssey, 2021-2025 Chrysler Pacifica, and Toyota Sienna vehicles equipped with QRT-Deluxe and QRT-Max wheelchair restraints. The retractors may not lock, preventing the wheelchair from being properly secured.

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.
