HYUNDAI issued a recall on the SONATA model

On certain vehicles equipped with an advanced airbag system, the Occupant Classification System (OCS), installed in the right front seat of the vehicle, may misclassify a small stature adult as a child and deactivate the passenger airbag. This would cause the right front airbag to not inflate in a crash that merits airbag deployment, and may result in injury to the right front seat occupant. Correction: Dealers will verify that the OCS does not recognize a properly seated adult occupant. After verification, the right front seat cushion assembly will be removed and reprogrammed.
