The weirdest thing happened tonight. At about 9:30 my wife and I heard a noise that sounded like maybe someone had smashed one of your big pumpkins on the sidewalk so of course I flew right out there and.....nothing. We stood there for a few seconds and heard what sounded like running water so I thought maybe someone's hose had burst across the street. I walked across the street and found out that the back window had blown out of our neighbors Saturn and was still very actively crackling, resulting in the running water sound. It is a 2002 and has it's original glass so it was not recently replaced poorly. Looking at it we noticed that a section across about half of the middle of the window about 4 or 5 inches wide (top to bottom) was bowed outward as though there was some serious pressure on the glass and there was a huge hole on the left and a smaller one on the right. Temperatures were mild and his windows were open. All I could think of was that maybe he has a frame issue because of rust or broken welds but there was no sign of anything in the body panels or under the car. Weird. Freaking GM!
