On 12/03/2023, We were involved in serious accident. During this accident, only driver door air bag was deployed. No other air bags were deployed.My wife was on passenger side. She was seriously injured and hospitalized for several days. She is still under medical care. I think air bags on passenger side was defective. Due to defective air bags system, my wife had serious injury and had to go for medical treatment, pain and suffering. We like to investigate defect in air bags. My wife was wearing lap and shoulder seat belt.However, seat belt was not activated and remain loose. Due to loose seat belt, she was injured. Please help. Thank you.
