Carrier/rack problems of the 2005 Chevrolet Corvette

My 2005 Chevrolet Corvette coupe started making popping and cracking noises at any and all rates of speed some time ago. At a higher rate of speed, the wind noise and whistling sounds are almost unbearable as the noises are so loud. I consulted with youman's Chevrolet in macon, GA as they are the only Chevrolet dealership in our are and they advised me that the top had stated to separate from the lower part and that we would have to purchase a entire new top. Once again, they did not even consider checking to see if there was a recall on this problem. Naturally, our greatest concern is the potential of the upper portion flying off while we are traveling at highway speeds and causing a potential accident to other vehicles or injuries. I recently starting taking the Corvette magazine and much to my surprise, I read that there is a recall on the top. I am disappointed that the Chevrolet dealership did not bother to check on this recall or to advise us of the recall if they were aware of it as we are regular customers and have spent a substantial amount of with them on this Corvette over the last seven years.
