Side/window Air Bag problems of the 2003 Jaguar S-type

My wife and I own a 2003 Jaguar s type. On the morning of the incident my wife got into the passenger seat and I in the drivers seat. When I turned on the ignition the passenger side air bag exploded, the dash cover that covers the air bag blew out just missing my wifes head, and completely smashed the windshield, ruining the cover and the windshield. It also blew out the sunroof breaking the plastic pieces that allow the sunroof to open and close. I called Jaguar who told me to have the car towed to the nearest Jaguar dealer. After 3 weeks I was told by the service manager that the cause of the air bag going off was a wire that came from the back of the airbag holder and connected to the airbag. The carrage that the airbag sits in had very sharp edges where the wire goes thru to connect with the airbag. As a result the wire rubbing on the airbag carrage rubbed thru the insulation of the wire causing the air bag to explode upon the turning of the key. Jaguar will do nothing to repair my vehicle ,but more then that someone is going to get killed as the metal dash plate over the airbag comes out at aprox. 800 miles per hour, enough speed and power to completely shatter the windshield, and sunroof.
