NHTSA complaint 11569571 - Filed Jun 28, 2023Failure Jun 16, 2023Austin, TXSeat belts
I got a notice from the car that the restraint system was malfunctioning. It said to go ahead and wear my seatbelt and go to the nearest repair shop. This is distressing and should not have happened. I’m afraid to drive it. I have no other means of transportation. My life was destroyed by a near fatal car accident in 1994 as I was enrolling in medical school. An 18-wheeler pulled out on narrow 2-lane Hwy with no shoulder. It ran through a very dense pine forest in east Texas. The trailer had only a bicycle sized reflector, and it was caked with mud. He was invisible. I couldn’t see him until my headlights shone upon the trailer. What is that? A distance of 50-60 feet, at most? Brights weren’t on. It was drizzling and little wisps of road mist were floating above the road here and there. I slammed as hard as I could apparently. As I swerved into the oncoming lane, the driver behind me watched in horror as my headlights swept across the entire length of the trailer. There was nowhere to go. I slid under the trailer and hit the axle going 45 mph. No time to stop. The driver directly behind me was an off duty police officer. He got out and ran over to the truck to tell the driver to stop. He didn’t know he’d caused an accident. The off duty policeman checked my car to see if there were any survivors. He peered into the dark through my window and found me alive and conscious. The seatbelt was still wrapped around me but the force of impact caused it to pop out of its socket. My head snapped forward on impact. It hit the airbag with such force, it ruptured fully on one side. I have a brain injury, was in a light coma for over four years. My life was so thoroughly destroyed, I had not one thing left but my 2 dogs and a Bible. My house, car, job, the ability to live independently, my future, and my personality—the person I was for the first 24 years of my life—all gone. Family abandoned me. I couldn’t function. Seatbelts must do their job. And truck drivers can go to hell.
