since I bought the car I've had no end of problems really.
first was sold the car with 2 cracked/welded rear alloys sorted by dealer.
drivers seat moves when driving, up and down on brackets this has being going on since the day I bought the car may 2014 and still isn't fixed passenger seat is also moving now.
they have said its a common fault and there is an upgraded seat base.
headlights are filling with condensation, ive been told there is an upgraded gasket/seal kit for the headlight units which is getting fitted on Monday.
rear shock is also now being replaced under warranty.
rear bumper was loose and rattling new brackets fitted under warranty.
the engine is leaking oil down the side slightly, they have said that it may need new gaskets, which should be covered under warranty.
there's a fair few problems which I've had with mine 2012 c63 to put it into perspective in 10 months of ownership I've done as many miles in courtesy cars (when they had one for me) as I have in my own. so its pretty p**s poor for a Mercedes.
when it goes in on Monday I will be asking for any more warranty issues or common faults to be brought to my attention as I will be getting them sorted as well.
but when I can eventually drive it its a fantastic car lol.
