I was in a car and I got into a accendent and I want to sue the car maker how do I do this or what can I do

If you were injured in the accident, you should consider hiring a lawyer to handle your case. They will hire a safety engineer to determine why your air bag failed and whether or not the failure either could have prevented your injuries or made them worse as a result of the failure. It is quite complicated and fairly expensive. They will need immediate access to your vehicle to inspect it.  The statute of limitations is 3 years to sue for your injuries from the accident or your claim will be forever barred.
