2005 GMC ENVOY XL 370 Structure Problems

2005 GMC ENVOY XL BACK REAR DOOR WINDOW BRACKET DETACHED THE FIRST TIME, THE SECOND TIME THE BRACKET ITSELF BROKE AND SHATTERED THE REAR WINDOW. THIS IS A DESIGN FLAW THAT PEOPLE ALL OVER THE COUNTRY HAVE EXPERIENCED. I AM TRYING TO GET WARRANTY TO COVER IT BUT THEY KEEP TELLING ME THEY DON'T COVER BROKEN GLASS, WELL IF THE BRACKET DIDN'T SNAP IN 2 THE GLASS WOULD NOT HAVE BROKEN. I AM VERY LUCKY I WAS NOT BLINDED BY THE EXPLOSION OF GLASS. I TOOK PICTURES WHICH SHOW PIECES OF GLASS OVER 20 FEET AWAY. I ALSO READ POST BY OTHER PEOPLE WHERE CHILDREN WERE CUT IN THE FACE A SCARRED BY THIS SAME EVENT. *TR

MAY 18, 2010 6PM DRIVING HOME FROM CHENA HOT SPRINGS ROAD AT THE SPEED LIMIT 55 MILES PER HOUR THE REAR HATCH PLASTIC WAS RATTLING AS USUAL AT THAT SPEED. AT ABOUT 1 BLOCK FROM COLLEGE ROAD TURNOFF WHILE STILL DRIVING ON JOHANSON HWY THE RIGHT SIDE OF THE PLASTIC COVER BROKE AND WAS HANGING DOWN OVER BACK WINDOW. I REDUCED MY SPEED AND STOPPED AND TRIED TO PLACE RIGHT SIDE BACK UP AND SEEN IT WAS STILL ATTACHED ON LEFT SIDE. I DROVE THE REST OF THE WAY HOME VERY SLOW. WHEN MY HUSBAND GOT HOME I HAD HIM REMOVE FROM LEFT SIDE. THIS PIECE IS 3 FOOT 10 INCHES BY 10INCHES. IT ALSO HOLDS MY (CHMSL) LAMP. THIS IS THE THIRD TIME IT HAS FALLING OFF. 2006 LOCAL GMC REPLACED BECAUSE THEY SOLD IT TO ME. 2008 IT FLEW OFF WHILE DRIVING 55 MILES A HOUR AND LUCKLY...
