"Divet in Head" on 2008

[Romie69]

Hi,
I've got an 08 that starting knocking pretty hard about a month and a half ago, took it in to the dealership to get 3000 mile tune up, and they called back saying I had a big divet on a head and thats what was making the hard knocking sound. Yes, I was a little late on getting the 3000 mile checkup, like about 1800 miles over but its still an 08.. A DIVET in a head? Sounds to me like soft metal and a manufacturing defect. I was two months past my warrenty work when I took it in about a month ago, so that sucks even more!! I didn't go and have the the dealership do my 600 mile check so the Suzuki rep is denying me so it's out of my pocket. Does anyone know if the Magnuson-Moss act might work here? Does anyone know who the Suzuki Rep for Colorado is?
What is the average cost out there for a new head, cam and to put it all back together again + labor and a wet finger.

Thanks for any help out there folks!!
