The warranty issue is the responsibility of the LBS you bought it from. If they have to strip and rebuild, that's their problem. This is why you bought a Bike, not a Frame, from them. It's fair enough that the frame will be the only replacement part, but the LBS is responsible for the Bike if it has failed in the warranty period, not the manufacturer or distributor. (this is precisely why our LBS's aren't cheap)
If you end up paying for a rebuild, I've got an old bridge near Circular Quay I will let you have cheap
Actually the warranty is the sole responsibility of the manufacture, the LBS' s role in this is as a distributor and manager of the process.
If you check out the fine print in the warranty cards you will find that all absolve themselves of any costs to tear down or rebuild the bike.
That being said most will absorb the labour costs.
