| Description of the problem | At 7:30 am on june 10, 2016, while driving north on rte. 495 in delaware in our 5-month-old mb - glc 300, the panoramic sunroof suddenly and without any warning exploded and shattered outward. The sound was as loud as a bomb. As shown in the photographs, nearly all the sunroof was blown out, with only a little glass remaining around the frame. The shattered glass fragments either flew off or settled on top of the shade screen. We were driving at approximately 65 mph and there were no cars directly in front of us or behind. We had the air conditioning system on with the outside temperature at about 70f. It was a clear morning and the sun had just risen. Our mb dealer in germantown, md said they were not aware of other instances of exploding glass sunroofs |
