What owners say
Sunroof exploded and shattered. I heard it while driving and held on tightly to the steering wheel before I realized what it was. The dealer and my auto insurance have been called, neither picked up, and I left each a voice mail message. No warning lamps, messages or other symptoms of the problem occurred.
My sunroof just exploded while driving on the highway without any impact or warning. It was a clear sunny day. There wasn't a vehicle in front of me. Nothing fell on my windshield nor sunroof. The sudden explosion and shattering of the glass was extremely startling. I had a mesh underneath the sunroof that contained some of the shattered glass so it did not fall on me while I was driving. I'm so thankful there wasn't a car behind me for the glass debris to fall on. Mercedes USA was not helpful, unresponsive for many weeks. They eventually declined repair coverage due to out of warranty, not manufacture defect nor safety issue.
Sunroof exploded while I was driving. No other cars around me, pretty day, not a very hot day. I’m driving along and suddenly hear a loud POP that sounded like a shotgun going off! I swerved, but thankfully did not leave the road. Shattered glass was contained in the cover of the sunroof as I didn’t have it open at the time. A huge hole is in my roof of my car! I called the dealership who said it was not covered under any warranty although I just got the vehicle in Feb of this year. He said I would have to contact corporate. I contacted corporate who said bring it in for an inspection. At the conclusion of the inspection on 10/8/24, they could not determine if it was a manufacturer defect or outside sources since they could not find a point of impact, because the glass was nearly all gone. I had to get my insurance involved. There was no warning whatsoever. The dealership said no recalls. It just exploded all of a sudden!
On 12/23 I was driving away from home for holiday, and my panoramic sunroof exploded. I was quite shaken as glass was everywhere, in hair, on me and of course in car. I suffered very minor cuts. Called Mercedes SOS. Mercedes customer care. Advised me to go to local dealer near home. 2019 GLC300W4 with ~26,890 miles at time of accident. Dealer, West Chester MB without looking said $10,484. Not under warranty because of year and miles. I see that in March of 2021, about 17,000 vehicles were recalled for sunroof problems, just not my specific model. Clearly, there is a problem.
