This Problem Across All Years
The sunroof glass blasted and shattered during a drive on an interstate highway. I was driving normally when I heard a loud sound like a tire burst or gunshot. Initially, I thought that my tire had busted. I took an exit and stopped to inspect the tires. I found them to be okay, but I was puzzled where the sound came from. I started driving again and observed that a lot of outside noise was coming, also there was a glass clinking noise so I stopped again to check. I found a hole in my sunroof and the shattered glass had fallen on the protective mesh cloth. That is when I realized that the loud sound was from this broken sunroof. It was something like that the sunroof had blasted outwards as the bump was going outside. Luckily, I didn't lose control of that sudden, loud sound and didn't get into a crash. Hopefully, the broken glass didn't fly and hit other cars.

When working in the rear cargo area, the door comes down without warning and does not break when it meets resistance trapping me between the body of the car and the descending door. A great deal of physical pressure must be employed in trying to get it to reverse direction. It is a struggle to get out from under the continually closing door. This has happend to me on three different occasions. There should be an automatic reversal when the door meets resistance not unlike a garage door.
The automatic windows open when the car is parked without being initiated by anyone. Think of it as phantom window opening. The vehicle occasionally reports a window being open when in fact they are all closed. When the phantom opening occurs there is not notice of a window being open.

I bought this car brand with 4800 miles directly from Mercedes a month ago. The check engine light has been on since the second week of ownership. The reason I’m submitting this report is because it’s been into warranty service 4 times. Each time Mercedes Benz says that it is a known issue affecting ALL GLC300 models. They also indicate that it is a software issue, but don’t have a patch for it. There are other things like Bluetooth, no radio audio, and the remote start that they are also attributing to this software glitch. However, the check engine light presents a MAJOR safety issue. Please force Mercedes to issue a software update recall to fix the incessant check engine light.
