Car was parked in garage and the moonroof was opened earlier in the day with no issues. There were no cracks at all in the moonroof and no rocks had hit the vehicle. As the car was parked in our garage with our 1 year old daughter still in her car seat and my husband and I were at the front of the garage, the moonroof shattered and the glass got all over the interior of the car. Again, there were no signs of glass and or wear on the actual moonroof during the day. Cadillac's moonroof department stated that it may have been due to a temperature change. This is ridiculous since we live in New Hampshire and the weather was a perfect 64 degrees and our garage was around 75. You assume that the glass in your car could withstand most situations. This could have been a major incident if we would have been driving on the highway when this happened and there are 6 other known cases of this on the safely website.
