Definitely get it warrantied if they'll let you -- and, IMO, they should.
I had a crank develop a wobble, which my shop thought was just a bottom bracket bearing going bad. Once they took it apart, though, they saw that the spider had come loose from the axle. They offered to replace it under warranty, and I asked if I could use the warranty as a credit towards a different brand & model of crank. They agreed, so I got a totally different, and better, crank.
BTW, I think that lefty version of the Bad Boy is a hot-looking bike:
