My Fairly New P600 Just Blew Up!

I have had my P600 for almost a year now and it might have 8,000 miles on it, and the other day I noticed a different "pitch" in it while idling and just thought it was breaking in finally. It didn't sound bad, just different. Well today I took it out for lunch and pulled it up once to about 9psi and when I let off the throttle it started a terrible howling and grinding. I can clearly hear the impeller hitting inside. WTF!! I have heard the horror stories about ATI not wanting to replace anyhthing.. anyone ever had this happen? What can I do? I am so pissed right now!
