Windshield problems of the 2007 GMC Yukon

2007- GMC Yukon xl denali purchased on 11/09/2007. 1 week after picking up this new vehicle we noticed distorted images when driving. This is most noticeable at night time. The windshield has numerous waves throughout, causing the images to be distorted. After driving for awhile you get a feeling you are on a boat, makes you dizzy and gives you a headache. The dealership referred me to GMC. GMC's donna mowet (866-790-5600 xt 12023 service request #71-622065992) reported to me via phone yesterday (05/20/08) after about 2 months, ". . . The technicians have determined that this is a normal normal characteristics of the windshield and that no further action will be taken by GMC or the dealership, hence it does not qualify for the new vehicle warranty. . . . . ". I requested I be allowed to return the vehicle to which she stated "it would not qualify for a buy back". Please keep in mind that no technician ever looked at my specific vehicle, the dealership informed me of that and handed me a service bulletin, explaining that I will have to contact GMC. In addition, I will like to point out that the service bulletin was issues on Feb. 2008 after the vehicles have been built and sold, not before they were released. There were no service bulletins available when I made my purchase and there was no warning advising me as a consumer that the windshield had normal characteristic flaws that may cause distortion while operating this vehicle. I am requesting that NHTSA please look at this matter immediately so no deaths or injuries occur and have GMC comply with the new vehicle warranty or have then buy the vehicle back. I would like to also state that our previous vehicle was a 2002 GMC Yukon xl denali and that we were happy and had no major issues nor was the wind shield warped for over 1000,000 miles.
