I was in a car wreck and my air bags did not deploy and my seat belt did not lock. The other vehicle involved in the car accident immediately deployed its airbags.

Vehicle is easily stolen, and is a safety risk for others. Kia's are getting stolen at an alarming rate and should be recalled! Not only are they getting stolen but they pose a major safety risk because the people stealing them are crashing them, running from police, etc. Damage to my own property as well as others (mine had mysterious damage but I have no idea who or what they hit). Something mu...
