NHTSA complaint #10402076, filed 2011-05, 150,000 miles

“The vehicle during a severe accident, in which the other drivers air bags were deployed, our vehicles airbags did not in fact deploy at any rate. Which put all passengers in severe danger causing injuries that could have been avoided if they worked properly. Also the drivers seat belt (which was worn at the time of the accident) due to the immense collision at one point clicks unhinged and would no longer actively snap back causing multiple injuries as well. This incident will call for suit.”
