I bought the GLC 220d about 6 months ago. I took my family for a vocation and we drove. My 2 kids in the back with my wife by side and me driving. When i came back my driving seat would not move forward or back and when I checked why found out that the electric motor that moves the seat is placed on a cheap platic and it broke in half and when I checked the passenger side found that it was also broken. I called my dealer and they quoted $1500 for each side. This is really shameful for a company like Mercades. They built there cars to last and it’s a off read version. My daughter is 16 and my son is 18 and i’m sure they didn’t deliberately kicked something or push there feet too hard. The plastic is so cheap.
