I'm curious if this has happened to anyone else. My fiance has a 2012 C30 R Design and this morning and she was pulling out of the garage to go to work, her car was making weird noise, I had her pop the hood and the timing belt was wearing through the cover. We shut it off right away and the belt was loose, the sounds had to be the either the roller or tensioner failing. I do not think it jumped timing at all as the engine sounded fine and the noise was all coming from the t belt area. The car only has 45k miles on it though. Maybe this is a freak occurrence, but 45k is way too early for any of the timing components to fail.
