So I got my MCS about 11 months ago now and after the first two months I had this horrible rattle at the fron on the passenger side. Took into my local dealer they looked at it heard it (thank god because it came and went, and lord knows that most of our problems dont occur if a tech specialist steps into the car, they have a way of disapearing). So they took the car in said it was something in the dash. Got my car back covered under warranty even though I had H&R coil overs on..he he. And the car was fixed. great! No not great abotu two months later the rattle is back and it is worse than ever now. It is totally annoying me and my wife and even though I have a different suspension on (oh time for a plug, I have a full set of H&R coil overs FS now, with 6k on them, let me know if your interested. Pics in gallery of what they look like) I did not think that it should come back. ANy input on how to solve this rattle under the dash or recomendations as to what I should do. I am taking it back into the dealer so hopefully they will fix it, but if they dont has anyone else had this problem and how did you fix it.
Thanks

i can only recommend you remove the dash and do a process of elimination
on the rattle trouble areas.
