I was in a car accident, and air bags didn't deploy.

NHTSA ODI 11740233

My wife and I purchased a 2024 Hyundai Tucson in June.  Since February 28, 2025 the SRS indicator lights have come on twice. Hyundai replaced the airbag twice.  In March, the emergency brake system red lights illuminated, and the car came to an abrupt stop.  Luckily, there were  no Cars behind me.  Seconds later, the car resumed, and the lights disappeared. Hyundai dealership took the car in and returned it in two hours noting they could not duplicate. Several days ago, the same thing happened with the emergency brake system. Driving at approximately 40 mph the car slammed on brakes and the dash illuminated again.  No cars behind me. The dealership returned the car once again, noting they could not duplicate.   The car has less than 8000 miles.  I won’t allow my wife to drive more than 10 miles alone.  It’s unsafe. The manual states the car is not to be driven with any of the sys indicators on and to do so would cause serious injury or damage to the car.   I will send attachments of invoices, NHTSA complaints and Hyundai manual info about unsafe condition.
