NHTSA 5-Star Safety Rating
Complaints about the 2019 Sienna cluster around the powertrain and paint/body finish. On the powertrain side, multiple owners report a whining noise from the transmission that develops over time, often noticed during acceleration. Several describe the transmission ultimately failing and requiring replacement. On the structural side, the most consistent pattern involves paint peeling and cracking on the hood, with owners describing the clear coat separating and the damage spreading across the entire hood surface over a period of a couple of years. A smaller number of complaints mention sliding door issues, including doors that fail to open fully and wiring problems discovered at the door. The transmission whining and paint delamination are the two clearest recurring themes across this complaint set.

By System
The 2019 Toyota Sienna has 8 recalls, the most serious being a door construction defect that can prevent side and curtain airbags from deploying in a crash or cause them to fire without warning.
The airbag issue stems from incorrect welds inside the passenger front door that interfere with the crash sensors, and represents a single defect covered across multiple filings. On the fuel system side, the fuel pump can fail while driving, cutting engine power without warning and leaving the driver unable to accelerate or maintain speed. Owners of Braun mobility van conversions face two additional concerns specific to those modified vehicles: brake line fittings may have been installed incorrectly, reducing hydraulic pressure to the rear brakes and lengthening stopping distances, and steering shaft extensions may fracture, causing a sudden and complete loss of steering control. Rounding out the list are two label-related recalls affecting certain vehicles distributed through Gulf States Toyota and Southeast Toyota dealerships: the load capacity label may become unreadable or display incorrect information, which can lead a driver to unknowingly carry more weight than the vehicle is rated for and affect handling and braking.
