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.
