The last time I drove my vehicle was Monday [XXX] which that day it was raining. I covered my car with my car cover that day because I don't use my vehicle often and being that it was raining I covered it and my vehicle was fine on this day. On Monday [XXX] it was raining as well, I took off my car cover off and when we opened the trunk of the vehicle we noticed that the trunk was wet including the bag to my car cover. We also noticed from the trunk opening that the vehicle had some spots of mold and there was also mold spots on the back of the seat right side of vehicle. I had an appointment at Mercedes Benz dealership in Portland Oregon to change my transmission & engine oil. As I drove the vehicle to the dealership for my appointment my daughter and I noticed drops of water falling on us and we didn't have our windows open because it was raining. The water was coming from the sunroof area and the sunroof wasn't open. We kept driving until we got to the dealership and once we got there we noticed that the back seats were also wet and the right side back seat had a few spots of mold on the seatbelt. We left the vehicle at the dealership. Today Wednesday [XXX] the dealership is stating that because the sunroof is used so much the parts in that area due to wear and tear it's no longer working properly. They are charging my daughter $500 for a water test that they did to the top of the sunroof and for changing the seals the the sunroof and the back of the trunk they are charging I believe an additional $736. I feel that there is something wrong with the sunroof this vehicle. My daughter only drove it for about one year and in May 2018 I became the only driver of this vehicle and to be honest I don't even open the sunroof at all. The dealership is stating that it will cost approximately $15,000 to fix this problem and if not considering this vehicle a total loss. We are going to be contacting our insurance and see what happens. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C.

After noticing my engine light come on, I had my vehicle checked out, the dealer informed (after spending $250) that the problem is the crankcase ventilation and it's a common problem. It seems the oh so familiar crankcase ventilation system is not working. This is a common problem with the GLC300 and Mercedes Benz needs to correct it. The engine is not being ventilated properly and the overwhelming smell of gasoline engulfs the interior of the vehicle. This is putting mine and the life of my family at risk, due to a faulty manufacturer issue. Mecedes Benz needs to obviously correct the faulty parts they use as soon as possible, before someone loses their life.

I pressed the "Park" button, but the transmission did not go into park. When I let my foot off the break, thinking that I was in Park, the car started rolling backwards. Thank God my wife was in the car and noticed the motion and shouted to me to break the car. I was able to stop the car before hitting anybody or anything, but it was dangerously scary.
