I have an intermittent rattle coming from the passenger side seat belt housing, did anyone experience this rattle on their C240. Each time I bring the car to the dealer the rattle by magic disappears.
Is there any fix to this rattle or is this normal since the car is new and certain parts or plastics react with time.

I have not noticed any rattling form my seat belts. I wonder if there may be something loose with the height adjustment portion of the housing. Does it rattle when there is someone in the seat? or with with no one in the seat? It may be only when no one is in the seat. If you have taken it to the dealer and you have had someone in the seat - then it may go away because the belt is on tension. Maybe have the guy sit in the back seat to see if that makes a difference.

this "rattling" occurs when in the seat and the black part of the seat belt in the housing hits the housing. only on imperfect roads do you hear it. the noise is barely noticable to anyone other than those next to the seat belt housing and using it.

i had the same rattle in the back, but it went away sometime, i thought is just me. this is before i drop my car. since now is lowered i think the dealer will think is because is lowered

my car is not lowered. i had a 'rattle' in the back that turned out the heat exhaust shield system i think the dealer labeled it was loose. this was due to the crappy roads i drive on in michigan and ohio. on many occassions a bump and pothole would hit underneath my car and i guess that ruined it. i now take the long long way to work (10 miles extra than the bumpy road) and it is a smooth quiet ride.

I had a rattle in one of my rear seatbelt mechanisms. Told the dealer during service and he did a minor adjustment. It hasn't rattled since.
