| Description of the problem | Exploding panoramic roof. On january 18, 2019, two hours into driving from new york to canada for a family vacation, without any warning and for no apparent reason the panoramic roof to our 2015 mercedes benz c300 4matic suddenly and violently exploded. At the time of the occurrence the highway road (i84e)was straight, smooth and we were at cruising speed (60mph), no cars anywhere near us in front or from the rear. The explosion sounded as if a bomb had gone off or if we had been shot. Tiny glass particles sprayed my entire family including my wife, 2 daughter (12,15) and our puppy. Luckily the sunshade covering underneath the glass roof caught the larger pieces of broken glass. After making sure the family was not injured i managed to find a large piece of cardboard that i duct tape to the roof and slowly made our way back home, ending our trip. Upon arriving home i did lots of research and to my surprise found that exploding panoramic roofs was more common than i had ever thought with many owners gone through the exact situation as i. Yet, mercedes refuses to acknowledge this issue and presently does not have a recall on their problem. To add insult to injury when i brought the vehicle to the dealership for a repair, the service advisor acted as if this was no big deal and also that he has never seen this issue in his 34 years of being there. I can only assume that this is a false statement since the vallet person who took my car said he has seen it on quite a few occasion. Mercedes benz of north america needs to address this situation before it becomes a fatal mishap. The sound and glass debris could have easily distracted me enough for me to lose control of the vehicle and cause an accident. Luckily no one was near our car. |
