Power Window problems of the 1998 Ford Mustang

While driving on the highway at 55mph, the left quarter window exploded sending glass fragments into the back and front seats of the car. Temporarily lost control of the vehicle due to window exploding. Was able to regain control of vehicle, pulled off the highway and notified police and obtained report. Notified insurance company and brought car back to glass shop who replaced the window the first time. Glass shop found a manufacturing flaw during assembly where screws were loose and binding against the glass when window was in the up position. Glass shop tightened loose screws, replaced window and gave no garantee this would fix the problem. Notified Ford of problem but they do not want to take any action. Notified dealer, they told me to call Ford. Catch 22, no one wants to take responsibility. This car is a safety hazard. Glass shop who found the problem is diamond auto glass 145 patterson Ave, wallington NJ 07057 (1-800-235-7487). My next step is to file a complaint against Ford motor company with the bbb. Since the car is leased, iam notifying the bank to see if I can get out of the lease due to the safety hazard of this vehicle.
