The Hyundai Elantra was redesigned for the 2001 model year. The Institute evaluated the 2001 Elantra and identified a problem with the airbag system. The driver frontal airbag fired late in two crashes resulting in high head injury measures.
All 2004 and later Elantra models have redesigned driver frontal airbags and all 2004 and later Elantras manufactured after August 2003 also include redesigned passenger frontal airbags (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). At the request of Hyundai, the Institute agreed to test the 2004 Elantra with the redesigned airbag system.
The Insurance Institute for Highway Safety has evaluated the crashworthiness of the 2004 Elantra with the redesigned driver and passenger airbags in three 40 mph frontal offset crash tests into deformable barriers. A fuel leak occurred in the first test. Hyundai identified a fuel hose clamp that was improperly positioned, which led to puncturing of the fuel tank during the crash. Hyundai has recalled the affected models to reposition the hose clamp. A second test was conducted to assess the effect of the fix.
In the second test, no fuel leakage occurred, but the driver frontal airbag failed to deploy. This led Hyundai to modify the frontal airbag deployment characteristics beginning with 2005 models produced after December, 2004. Also, Hyundai will initiate a recall to modify at its cost 2004-05 models produced earlier. The Institute tested a third Elantra with the modified airbags, and the driver airbag inflated properly.
The evaluation of the Elantra below is based on the first and third tests, except for the structural rating, which is based on all three tests.
Measures taken from the neck and chest indicate low risk of injuries to these body regions in the first and third tests in a crash of this severity. A high head acceleration occurred when the dummy's head hit the steering wheel through the airbag, indicating that head injuries would be possible. Head acceleration from the B-pillar hit was high in the first test but low in the third test. Forces on the right tibia in the third test indicate that injuries to the lower leg would be possible.
Restraints and dummy kinematics
Dummy movement was reasonably well controlled in the first test and well controlled in the third test. During rebound in both tests, the dummy's head hit the B-pillar.
