Moderate overlap front

Rating applies to 2004-06 models

Tested vehicle: 2004 Hyundai Elantra GLS 4-door

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. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on the driver door or adjacent B-pillar.) 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 moderate overlap frontal 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 initiated 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.

Driver restraints and dummy kinematics

Action shot taken during the third of three frontal crash tests.

The dummy's position in relation to the steering wheel and instrument panel after all three crash tests indicates that the driver's survival space was maintained well (third test shown).

A high head acceleration occurred when the dummy's head hit the steering wheel in the first and third tests (third test shown).

Forces on the lower right leg were high enough to indicate the possibility of injury in the third test.
