EVER SINCE I PURCHASED MY 2004 YUKON XL IN DEC. 2003 THE STABILITY TRAC SYSTEM HAS BEEN DISABLED. THE DIGITAL READ OUT JUST BLINKS DISABLED. MY LOCAL DEALERS KEEP TELLING ME THAT GM IS AWARE OF THE PROBLEM, BUT CAN'T GIVE ME ANY ANSWERS. YOU WOULD THINK SOMEONE WOULD KNOW SOMETHING BY NOW. THE REASON I PURCHASED THE YUKON WITH THE STABILI-TRAC WAS FOR THE SAFETY OF MY FAMILY. I SPENT ALOT OF MONEY TO BUY THE VEHCILE AND NOW FEEL CHEATED DUE TO NOT HAVING WHAT I REALLY PURCAHSED THE YUKON FOR.*AK
