The car Hydroplaned while driving on the interstate, spun out of control and slammed into a tree in the rear end. My son was going approximately 65 mph and upon impact no airbags deployed and the steering wheel was in his hands after impact. His seat broke and collapsed into a laying position. His head sustained a huge blow to the interior side of the car in addition to another head injury in the front, a fractured wrist and multiple bruises along with a sore neck & back. The insurance adjuster saw the car and could not believe the steering wheel came completely detached in addition to no airbags deployed. My son is [XXX] ” and weighs [XXX]. I would have expected from his body weight alone the side airbag deploying. The car is totaled beyond repair. The car had no warnings or indicators regarding faulty airbags or steering issues.
