--The sunroof glass suddenly shattered without any prior warning while the vehicle was in driving on the road. Some of the broken glass pieces scattered throughout the interior of the car. --The sudden shattering of the glass roof created a hazardous situation for the driver and passengers. Although no one was injured, we were shocked and initially thought it might be an explosion or gunfire. Additionally, the tiny glass shards is very dangerous. --We have called dealer and they said there might be several similar cases reported. --The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives, but I have called dealer and insurance company. --There were no warning lights, messages, or symptoms indicating a potential failure before the incident. The glass shattered unexpectedly and spontaneously while driving.

FUEL/PROPULSION SYSTEM
During cold weather there is always a gasoline smell when starting the engine that eventually goes away. On 01/20/2025 the smell was so intense that I decided to stop the engine and leave the car outside the garage just in case. Upon opening the hood, I noticed an amount of a type of liquid similar to gasoline right on the undercarriage protector covers. I could not reach with my hands but instead I used a wood stick that I had in the garage. I reached the liquid and submerged the stick for like 10 seconds and pulled it out. When I smelled it, it indeed smelled like gasoline. I took the stick to the back patio and lighted it up and as I suspected, the tip of the stick lighted up like a torch. I called a nearby mechanic and made an appointment to check it out and today (01/23/2025) I am bringing it in. I went to Youtube and found numerous videos showing this "well known issue" with some of the fuel lines in this type of vehicle which I believe is a tremendous hazard. Just imagine that when I turned the engine up on 01/20/25 the engine could had gone up in flames burning not only the vehicle, but my entire house with maybe my family inside? Please take serious note on this issue and try to come up with a mandatory solution for the problem. I will let you guys know the findings from the Mercedes mechanic once the job if completed in case you need more information. Thanks

POWER TRAIN
The rear differential failed, causing both rear axles to be broken and the vehicle to lose all propulsion on a city road. A noise in the drivetrain under acceleration was first reported to a dealership in Nov 2023 about five months prior to the failure, but the report was dismissed as tire slippage and not addressed further. Then the failure occured in April 2024, and the vehicle was towed to a dealership and repaired out of warranty at great expense. There were no warning lights or symptoms immediately prior to the failure.

ENGINE
I have noticed a recurring issue during the colder months where there is a strong gas smell inside the cabin, and I have also observed fuel dripping into the engine compartment. This issue seems to occur primarily in winter conditions. I was surprised to find that there has been no official recall or service bulletin addressing this concern, especially given the potential safety implications.

There was a recall for this issue before. RecallCampaign2015100007
