Moderate overlap front

Rating applies to 2006-10 models

Tested vehicle: 2006 Hyundai Sonata GLS 4-door

The Hyundai Sonata was redesigned for the 2006 model year.

The Insurance Institute for Highway Safety has evaluated the crashworthiness of the Sonata in two 40 mph moderate overlap frontal crash tests into deformable barriers.

During the first test, the driver seat back failed to maintain its adjustment in its locked precrash position, resulting in forward rotation of the seat back into the inflated airbag. The seat back then moved rearward and after the crash was found in a semi-reclined position. Postcrash inspection showed the lap portion of the driver lap/shoulder belt was partially caught beneath the seat back adjustment lever and had likely activated the lever during the crash.

Starting on August 1, 2005, Hyundai put into production a new seat back adjustment lever designed to minimize interaction with the seat belt and ensure the belt cannot slide between the lever and the plastic trim on the side of the seat. Hyundai has recalled all 2006 Sonatas manufactured before August 1 to replace the levers at its cost.

A second test was conducted to assess the effect of the fix. Hyundai sent the Institute a replacement seat back adjustment lever that was retrofitted in a Sonata produced before August 1, 2005. In the second test, the seat back remained in place.

The evaluation of the Sonata is based on the second test, except for the structural rating, which is based both tests.

Action shot taken during the second of two frontal offset crash tests.

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

Smeared greasepaint above the dummy's head indicates where the head hit the roof rail during rebound in the second test. Head acceleration from this hit was low, but forces on the neck were high enough to indicate the possibility of injury.

Intrusion into the driver's space was minimal in both tests, and all leg and foot injury measures were low (second test shown).
