2005 Toyota Sienna
minivan
Moderate overlap front: original test
Tested vehicle: 2004 Toyota Sienna LE
Rating applies to 2004-10 models
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 moderate overlap frontal 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.

Side: original test
Tested vehicle: 2005 Toyota Sienna LE with optional head curtain airbags for all three rows of seats and optional front seat-mounted torso airbags
Rating applies to 2005 models built after February 2005
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.

| Driver head protection The intruding barrier came close to the dummy's head in this test. Although the barrier did not hit the head, this near miss indicates that only slightly different crash circumstances could produce a direct hit to a person's head. |
