I can understand your pain but you cannot let your emotions impact your reasoning and decision making. You have 2 things against you...you are out of warranty and you are not the original owner. Very few homes are perfect when first occupied and I believe the developer has a very good and commendable record of fixing anything identified as a problem within the first year AND will even come back and fix something that was identified during the first year but reoccurred after the warranty period expired. Add to this the fact that you never had a relationship with the builder, I would think you have a weak arguement. As others have said this could have eben identified during your home inspection or due dilligence on your part in simply asking for utility records prior to your purchase..and it would have been obvious if the bills were as outrageous as you have described.
NOW a friend of ours recently had a simialr situation as yours. They bought a Premiere home in 2005 and just sold it in August 2008 (Last month). The new buyer had a home inspector come through and they found that the home only had 4 inches of insulation in the attic rather than the required 8-10 inches. The new buyer placed the onus on the seller to get the problem fixed and the seller went back to TV Warranty to correct a "latent Defect" in the construction of the home even though the house was more than 3 years old. The Village inspector came by and agreed with the home insection report and had additional insulation blown in at no cost to the seller. SO these problems are resolved on a case by case basis (with my example comming out in favor of the original home buyer) but I think you not being the original buyer from the Developer does have an impact on the outcome.
