Side/rear Glass problems of the 2010 Toyota Camry

I drive a 2010 Toyota Camry with about 7500 miles. At about 11:20 a. M. Today my rear window exploded as I stopped at a traffic light on arlington mill road in arlington, va. When the explosion occurred I did not know what it was and looked around for the source. When I looked to the rear I saw the window in fragments. I saw no one around me although there may have been several vehicles stopped at the light behind me. They all drove around and continued on when the light changed. I crossed the light to not hold up traffic and then called aaa to determine what to do. I take product pictures of products I market over the internet and had a camera with me, so I took several pictures. I did not call the police as I could see no one who might have fired a gun or thrown a stone. Aaa advised that I should not drive the car as it was not safe to other drivers if shattered glass flew off into the road way. I also did not want to drive or in any way disturb the vehicle prior to examination by the dealer. The temperature was 82 degrees and the ac was on. Also, the side windows have been tinted dark as I had intended to use the vehicle for a livery service. There is no tint on the front and rear windows. I received the customer satisfaction number (1-800-331-4331) to call Toyota, have called several times only to be placed on hold for significant periods of time.

Husband, daughter and myself got into our 2010 Camry, when our daughter closed her rear door, we heard a cracking noise and turned around to see the back windshield shattered and a huge hole in the middle. There was glass scattered all over the back seat. Luckily our daughter was not injured. There was no rock, branch or thrown object as a cause of the shattering. Car was parked in driveway. Had been driving car earlier in the day with no problems. Temperature outside roughly 40 degrees and car had just been turned on.
