Airbags failed to deploy at 30-40 mph head on collision. Vehicle had an airbag light come up, was inspected by Ford and the RCM module was replaced as directed by manual. Airbags were also inspected at the time. Lights were cleared after the replacement. Was the car not reading the speed at the time of the accident? My wife and 2 toddlers were in the vehicle at the time of the accident. I have a wrist injury and whiplash. Injuries could have been worse if it was a vehicle of twice the size or a semi.
