The problem here is not that the engine had a problem, but that the engine has been underutilized.
In all likelihood, the engine was not driven enough and deposits in the engine hardened and stuck to internal engine parts. Now with the cleansers in the new oil attacking these deposits - they break away and float throughout the system. The place the oil passageways tend to end is the hydraulic lifters. They collect lots of loose junk from the engine.
When these lifters get clogged, they stick partially compressed which creates a gap between the lifter and the pushrod. Under use, this gap sounds like a metal to metal knocking as the engine turns over. This is likely the noise the owner is hearing.
If it were a "rod knock" there would have been some indication prior to this, it doesn't just happen, and that problem is typically from neglect, abuse, or other lack of preventive maintenance. This doesn't seem to be the case here as th engine is fairly new.
I agree that the company should not be liable for this. For the consumer, letting the engine run at idle for a while to heat up th oil and allow it to enter the clogged passageways and refill the lifters, and exchanging the oil and filter usually will clear this up. In the future, running your engine weekly should prevent this embarrassing situation from happening again.
FWIW: I was a diesel and gasoline technician for over 15 years.

You purchased something with a 3 yr warranty. Its apparent that the warranty is now over and you still want help? With the current state of the economy, do you think companies are going to stick their necks out any further than they have to? This may sound harsh, but looks like they fullfilled the warranty, and you asking for even more?
