Airbag and steering wheel problems. Neither driver's nor passenger's airbag deployed in a major crash. Our truck was hit by a fully loaded dump truck, speed unknown. Our driver had "mustang sign," bruising to chest. Passenger had seatbelt bruising. No warning lights or other indication was present to indicate that there was any problem with the airbags. We are the original owners and there was no previous use of, nor work done on the airbags. Steering wheel collapsed onto driver's legs, which we were told is common for adjustable steering wheels. Vehicle was totaled and is at junk yard. We have requested the collision report and can provide upon request.
