NHTSA Complaint #10205946 — 2008 BUICK ENCLAVE

I RECENTLY BOUGHT A BUICK ENCLAVE 2008. WHILE DRIVING I ROLLED DOWN THE BACK WINDOWS TO LET SOME AIR IN THE NEXT THING I HEARD WAS A TERRIBLE NOISE AND IT HURT MY EARS, THE FASTER I DROVE THE WORSE THE NOISE BECAME. I TOOK THE ENCLAVE BACK TO THE BUICK DEALER AND AFTER THEY DROVE IT THEY ALSO HEARD THE NOISE. FROM WHAT THEY TOLD ME IT IS BECAUSE THE ENCLAVE HAS A LOT OF AIR SPACE IN THE REAR OF THE VEHICLE AND THAT IS WHAT CAUSE THE NOISE BUT, WHY DOES IT NOT MAKE THE NOISE WHEN, I OPEN THE DRIVER WINDOW ALL THE WAY DOWN?? THEY COULD NOT ANSWER THAT QUESTION. HOWEVER I DID FIND OUT THAT ALL OF THE BUICKS AND GMC'S ARE BUILT THE SAME AND MAKE THE SAME NOISE. I ENJOY THE ENCLAVE BUT I DO NOT LIKE BEING ABLE TO OPEN THE REAR WINDOWS OF MY ENCLAVE. CAN YOU HELP ME OR TELL ME WHAT I CAN TO TO RESOLVE THIS PROBLEM? MY WIFE AND I ARE BOTH IN OUR MID 60S AND WE WANTED TO ENJOY A GOOD VEHICLE. THANKS JAMES BOOT *TR
