Side/rear Glass problems of the 2001 Dodge Stratus

I was driving my 2001 Dodge Stratus on the interstate. I was going approximately 70 mph with no other vehicles around me. I heard what sounded like a shotgun blast coming from the rear seat. I looked back and reliazed my right rear window had exploded. I went to the dealership were I had purchased the vehicle two weeks before to see if they could explain what happened. I was told that the car creates a vaccum and that was what caused the window to explode. If this is the case I think something needs to be done about this issue. Lucky for us there was nobody in the back seat.

While husband was just sitting in vehicle his back windows exploded. No injuries were sustained.
