5/5 Overall
NHTSA 5-Star Safety Rating
For the 2016 Toyota Sienna, the dominant complaint theme centers on the power sliding doors. Owners across multiple reports describe the driver-side sliding door failing to latch, not closing completely, or triggering false door-open warning lights while driving. Several owners also report the door closing abruptly or unexpectedly during entry and exit. The structure category, which is where these door complaints land, accounts for the largest share of complaints filed for this model year. Beyond the doors, a smaller cluster of owners reports a loud whirring or grinding noise from the rear of the vehicle, which some trace to a rear bearing or coupling assembly showing wear after higher mileage. Seat belt and electrical complaints each appear in a handful of reports but don't form a clear pattern beyond individual cases.

By System
The 2016 Toyota Sienna has 4 recalls, the most serious affecting mobility van conversions where rear brake hoses or brake line fittings can fail and cause a significant loss of braking power, raising the risk of a crash.
Both brake recalls apply only to vehicles converted into wheelchair-accessible or mobility vans: in one, rear brake hoses routed too short can rub against the axle and wear through; in another, incorrect brake line fittings can drop pressure in the rear braking circuit. On the occupant safety side, a narrow window of vehicles built over a few days in February 2016 may have incorrect front seatbelt height adjusters that can tear away from the B-pillar in a crash, leaving the occupant without proper restraint. There is also a door concern across a wide range of model years: if a power sliding door is stuck, such as when frozen shut, it can later open on its own without warning, including while the vehicle is moving.
