On May 2, 2015, at about 10:00 a.M. we were driving to the scranton, pa, area. We had just entered the on-ramp to I-81 North from rt. 309 when we heard a very loud bang and roaring sound similar to a door on a jet blowing off mid-air in a movie. There was nothing on the road to run over and the closest vehicle to us was a truck tractor at least 500 yards ahead of us and not driving on an angle that would send anything airborne to our area; nor were we near an underpassr. We put our flashers on and pulled over at the first safe area. Upon checking our vehicle, we discovered our sunroof glass had 'exploded' with an approximate 8-10 inch circular hole dead center and the rest of the glass fractured. We had the interior sunroof covering pulled closed when this occurred. The edges of the hole were bent slightly upward indicating an upward force. We didn't run over anything and nothing struck us, so we were fairly shocked. We checked our cell phones and discovered independence Toyota, hazelton, pa, was about 5 minutes away at our next exit. We pulled in and both the sales people and service people examined the damage and were as surprised as us. Nothing was found in the glass debris that would indicate something struck the glass. Independence Toyota was great by cleaning up the glass, placing two layers of heavy plastic over the sunroof opening and taping it shut. I am a retired police lieutenant. I know what impact damage looks like and this was not it. Upon checking online, this occurrence appears more frequently than one would think in various makes of vehicles. Price Toyota in new castle, de is declining to cover this under warranty citing this is normal glass breakage. I have had windshields struck before. This is not remotely close. It is not okay to be driving your vehicle and suddenly have the sunroof "explode" with no causing factors present.
