2003 GMC YUKON DENALI Structurebody Problems

I LIVE IN FLORIDA- IT WAS APPROX 8 AM, SITTING OUTSIDE DRINKING COFFEE ON MY PORCH. VEHICLE HAD BEEN PARKED SINCE PRIOR AFTERNOON AND WAS LOCKED (ALARM ENGAGED). SUDDENLY, MY REAR WINDOW SPONTANEOUSLY 'EXPLODED'. THERE WAS GLASS EVERYWHERE BOTH INSIDE AND OUTSIDE OF THE VEHICLE. AFTER RESEARCHING WHAT COULD'VE CAUSED SOMETHING LIKE THIS TO HAPPEN, THERE ARE INNUMERABLE REPORTS OF THIS HAPPENING TO OTHER GMC OWNERS WITHOUT ANY PLAUSIBLE EXPLANATION. THIS IS A VERY CONCERNING ISSUE AS GLASS FLEW EVERYWHERE IN AND AROUND MY VEHICLE AND IT IS BY PURE LUCK THAT MY 15 YEAR OLD DAUGHTER AND USUALLY AT LEAST 1-2 OF HER FRIENDS, ALONG WITH MY ONE YEAR OLD DAUGHTER, WHO NATURALLY, IS IN THE REAR OF THE VEHICLE. MYSELF OR ANYONE ELSE MERELY WALKING BY THE VEHICLE COULD'VE BEEN INJURED JUST WALKING BY. HAD SOMEONE BEEN NEAR MY VEHICLE IN A PUBLIC PLACE, I.E. GROCERY STORE PARKING...

THERE ARE SEVERAL PROBLEMS WITH MY 2003 YUKON DENALI. FIRST, THE DASH TRIM IS CREAKY AND MAKES ALOT OF NOISE. THE AIR CONDITIONER IS NOT VERY COLD. WHEN I BREAK AND SLIGHTLY RELEASE I GET THIS MOANING LIKE NOISE FROM UNDERNEATH THE TRUCK. FINALLY, ON ONE OF THE RUNNING BOARDS THE PAINT IS PEALING OFF. I AM NOT VERY PLEASED BY ALL THESE DEFECTS, ESPECIALLY FROM A 50,000 DOLLAR TRUCK.*AK
