Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Toyota Sienna was redesigned for the 2004 model year.

The Insurance Institute for Highway Safety has evaluated the crashworthiness of the Sienna in two 40 mph frontal offset crash tests into deformable barriers. Two tests were conducted because a major fuel leak occurred in the first test. Toyota identified a defect in the manufacturing process of the plastic fuel tank and recalled the affected models. A second test was conducted to assess the effect of the manufacturing fix. For this test, Toyota retrofitted a redesigned fuel tank into the van. Due to the similarity of results (except for the fuel leak), the evaluation of the Sienna is based on both tests.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity. Head acceleration from the B-pillar hit was low in both tests.

Restraints and dummy kinematics

Dummy movement was well controlled in both tests. During rebound, the dummy's head hit the B-pillar in both tests.

Side crash test ratings can be compared across vehicle categories.

The Toyota Sienna was redesigned for the 2004 model year. Beginning with 2005 models manufactured after February 2005, changes were made to the vehicle side structure and to the optional side torso airbags to improve occupant protection in side impact crashes (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door). Beginning with 2006 models, side airbags were made standard.

Two tests of a 2005 Sienna were conducted, one with optional side airbags for the driver and rear passenger, and one without. Both were manufactured after the structural and airbag modifications had been made. These vehicles are rated separately, except that the structural ratings for both vehicles are based on both tests.

Injury measures

Driver — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Passenger — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Head protection

Driver — The dummy's head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof and a side airbag that deployed from the seat.

Passenger — The dummy's head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.
