I had just picked up 250 pieces of chicken from giant Eagle to feed the homeless at the ywca and placed the boxes in the back of my vehicle. As I drove down the street the window began to fog so I turned on the defrost. Within minutes of turning on the defrost, the window shattered into pieces. I ended up having to throw away over 100 pieces of chicken, but luckily no one was hurt. I have called the dealership and filed a complaint with the corporate office, but they say they cannot assist. After speaking with candice at GMC, @866-790-3600 ext 5923331, I was told that the extended warranty I purchased does not cover glass. I bough the car used almost a year ago, purchased the extended warranty to replace the bumper to bumper coverage, so why doesn't it cover glass" what is even more frightening to me is how does a window just shatter" this is a defect that needs to be address and this should be covered by GMC. I have researched and found that this has happened in other GMC vehicles and perhaps this needs to be a class action law suit before it will be properly addressed.
