That doesnt sound right, especially if you're under warranty. But, living in the Garden State, who knows? The dealer a wise guy or what? 
Well.....keep in mind...there ARE reasons NOT to replace something under warranty. Don't bash the MoCo/dealers all the time. Not saying that's the case here. But let's say for example...(and I know NONE of us do this)...say you're washing your bike. Unknowingly, your rag drops on the ground as your drying your bike...next swipe and swoosh...there is a nice scratch in the paint. OH CRAP! now, do you take that back to the dealer and attempt to claim it? Or a stone chip..or, or, or...
Again..not saying it happend here..but would you ride your bike when there is salt on the road? Of course not. But believe it or not...some people do.

Then they don't WASH the bike and they park it for a while. All of a sudden you get corrosion and chrome peeling....maybe even a bubble under the paint because there was a small stone chip?
There's always two sides to every story.
Sure wish it's warm up to get rid of this white crap all over. Of course, I'd need a good shower to boot in order to wash the roads off.
Prayin for spring to hurry up and get here.
Cheers,
