+1 on making Trek aware of your problems. Trek will want to find the "root cause" of the failure. More than likely it will be an issue with the vendor that supplied the wheels and will only cost Trek the time to investigate. Trek will have people (vendor assurance) that it's their only responsibility to do so and will have a policeman's mentality. It's their job to protect Trek's reputation. I'm not saying it will be a fast experience but hopefully the replacement will be built with extra care. This kind of after the fact quality control is one of the reasons they're more expensive even if they use the same components as "big box" bikes.
