2004 Cadillac Deville wipers, windshield & visibility problems

Tl*the contact owns a 2004 cadillac deville. The contact stated the sun roof glass shattered and caved in on her and an occupant while driving 50 MPH. The vehicle was driven onto the emergency lane because it was uncontrollable. The driver and the occupant were injured and had to be treated at the emergency room. The vehicle was driven to the dealer who repaired the sun roof under warranty. The failure mileage was 66,000.

Right front window dropped/broke down causing a $500 repair. Three months latter the left rear window also broke causing another $500 repair. Now, in 2014 the right rear window has broken, while driving on the freeway, startling my wife and grandchild with another very loud bang! This is a continuing problem on a car that only has 48,500 miles on it, and is always parked inside a garage. There are way too many reports of this happening for the feds or GM not to do something about this failure!
