Luckily there was no other cars around me and I was able to slow down and pull off the hway. Coincidentally, I was just a mile from the dealership and immediately took the car to them and they gave me loaner car and took it in to repair under warranty. Approximately 18 months later, the air bags failed again and the car was just past warranty so I paid for the repair but contacted Hyundai and they reimbursed me.Hyundai told me they had problems with the design of the airbags and redesigned it which is what my car was then equipped with.
