Zero Turn Mowers

I purchased a zero turn RZ4219 back in late May. I found online after the purchase that this model apparently has a design flaw with the belt, either coming off, breaking off or both. After my first usage of the mower I noticed the belt is frayed. What has Husqvarna done to solve this problem so that it will be fixed by an authorized repair center when I take it in? If it can not be fixed will Husqvarna offer any other options, as with a vehicle you are protected by the lemon lay for a known faulty equipment/design.
