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

The 2003 Infiniti QX4 is a twin of the tested vehicle.

The Nissan Pathfinder was redesigned for the 1996 model year, and the Infiniti QX4 was introduced in 1997. All 1997 and later Pathfinder and QX4 models manufactured after October 1996 include structural changes to improve occupant protection in frontal 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). The QX4 was discontinued after 2003, but the Pathfinder was continued through the 2004 model year before it was redesigned again.

The Institute has evaluated the crashworthiness of a 1997 Pathfinder with the structural changes in a 40 mph frontal offset crash test into a deformable barrier.

Injury measures

Measures taken from the neck, chest, and legs indicate low risk of injuries to these body regions in a crash of this severity. Forces on the head as it moved into the airbag indicate that injuries to the head would be possible. Head acceleration from the B-pillar hit was low.

Restraints and dummy kinematics

Dummy movement was reasonably well controlled. There was too much upward and rearward movement of the steering wheel. During rebound, the dummy's head hit the B-pillar.
