While some of the Sienna's crash test ratings haven't been updated, it's always been a star performer–and now it has some of the most modern safety tech available on the market.
All Sienna minivans come with side curtain airbags that offer protection for all three rows of seating, as well as a driver-side knee airbag. A pre-collision protection system that preps the car for an imminent accident is offered on higher-level trims, as is dynamic cruise control. A rearview camera is now standard on the LE model and all models above it in the hierarchy, and front and rear parking sensors are standard on the Limited. Blind-spot monitors are now standard on the XLE and Limited and available on the SE, and they incorporate cross-traffic alerts, for backing out of parking spots more safely.
Visibility is excellent in the Sienna, and its upgrade rearview camera offers a 180-degree view.
The National Highway Traffic Safety Administration (NHTSA) bumped the Toyota minivan up to an overall rating of five stars, although it took a rerun of its side tests--and apparently, a very strong performance in that test, to overcome its four-star frontal test.
The Insurance Institute for Highway Safety (IIHS) has called the Sienna a Top Safety Pick in the past, with top 'good' ratings in all categories--but since it hasn't yet been tested in the new small-overlap frontal test, it does not qualify for the award this year.
