The vehicle had been previously serviced in 2019 by a Mercedes-Benz dealership. The panel between the windshield and the panoramic sunroof was replaced due to paint issues. While driving down the highway, I heard a constant noise but was unable to locate it when driving above 60 mph, after a few minutes the panel ripped off the car onto traffic behind. Thankfully the car behind me was able to brake and was not struck directly by the panel, but did run it over. This VIN is currently not in recall for this issue, but the car does meet the criteria for recall.

I was driving on the highway and the front panel in between the windshield and the sunroof detached from the car and went flying. Luckily there was no one driving behind me at the time. It was previously repaired in December of 2018. I did some research and saw that my make and model car had a recall issued for this type of incident if you had ever had this part repaired stating that it was done improperly. See: NHTSA CAMPAIGN ID: 21V197000 RECALL DATE: 2021-03-22 For some reason, my VIN is not included in the recall. I'm not sure why not since this exact incident happened to me. I contacted Mercedes-Benz USA and they are not helping and would not tell me why my car is not included in the recall.

Last week on March 31st I went to turn my vehicle on since I wanted to move it from my parking spot in the neighborhood to my garage in order for me to go to the grocery store shortly with my 2 month old baby. As soon as I put the key in the ingnition slot and turn the key I heard like a zapping noise instantly and noticed in a matter of seconds smoke coming from underneath the steering wheel area. Sort of near the floor os the drivers side. I immediately hop out of the vehicle to see what had happened and where the smoke was coming from and just as quickly flames started coming from the same area as the smoke. I called 911 and in less than 3 minutes the entire inside of the vehicle was in flames, burning down. The flames then blew all the windows and moon roof trying to escape the vehicle and by the time the fire rescue came most of the vehicle was gone. I thank god I didnt get to move this vehicle as I had originially planned because it would have cost me my life and my families. I owned this vehicle only about 3 years and it never ever gave me problems. All of its maintanance was up to date and never had any electrical issues or major repairs due to anything. I am almost certain this was a fuse or electrical problem that caused the vehicle to burst into flames due to the zapping noise I heard as the vehicle was being turned on. I had been driving this vehicle perfectly fine which is why this came as a huge surprise. I want to make sure others are aware of this issue since its a huge risk. My specific vehicle has never had any recalls and im always checking and up to date with everything. I will be contacting the Mercedes Benz manufacturing company to let them know of this as well.

I was driving my car on local streets, suddenly I heard a cracking noise from the sunroof. After that I pulled my car aside and notice that there was a small crack on the sunroof. (see attached photos) there was no falling foreign objects, no impact from the weather. I have no clue what is the cause of the day crack. My first reaction was to call the insurance company and find a parking lot to store the car. After I contacted the insurance company and I was on my way to the parking lot, the sunroof shattered completely. Some of the glass piece even fell and caused injury to my wife. This was definitely a manufacture defect because there was no impact from the outside at that time and you can also clearly tell from the picture of the crack. It is not caused by any fallen foreign object. I was not able to drive the car anymore at the risk of my family's injury so I called the mb roadside assistance to have the car tolled. The shattered sunroof not only cause diversion of the driver's attention and also cause body injury from the fallen glass pieces. Mercedes is not responding to the complain. Dealer is taking the responsibility on this issue and charge me $2,400 to repair the sunroof. I did a search on internet and I noticed that similar cases are widely seen worldwide, see below links to recent incidents in California and uk.

He bought the case to the court in California. I really think Mercedes should be responsible for this issue and evaluate the risk, consider a recall since this is not an uncommon case.
