My husband and daughter were in the house and heard a loud shatter. They went into the garage and saw that the rear window to my 2007 GMC Envoy was shattered. There was not anyone in or around the vehicle. The vehicle had not been driven in over 3 hours. There was frost on the windows 4 hours earlier, and the rear defroster was used, but did not have any problems with it. The hatchback and/or window was not opened or used the preceding 2 days.

2007 GMC Envoy. Driving on interstate on Saturday 1/8/11, cold snowy day, all of a sudden steam started to come out of vents, all windows fogged up could not see and strong smell of antifreeze. Had no place to pull over. A good thing my wife was in passenger seat she took off her coat and kept the windshield clear till I could exit the highway. Took car to dealer and was told the heater core was leaking. This could have caused a bad accident if we did not act quickly.

Weather is in the single digits and I parked my 2007 Envoy denali in my drive. I don't have a garage so it sits out in the extreme heat add cold. I thought I heard a noise outside and when I looked out my rear window was completely shattered. Nothing hit it, nobody was down our isolated lane, it just decided to fail. I looked online and there are other owners mentioning similar problems with Envoy and trailblazers over the years. I have had multiple vehicles over my 54 years and I have never heard of a rear window exploding on it's own. To cut to the chase my vehicle was 9 months out of warranty, but I did get some money from the GM rep and the dealership. They told me the cost of the replacement was $850 and I was asked to chip in $200. I think this is different than tires or brakes wearing out with time and I thought they should completely cover the window failure. I am concerned that in another few years I could have the same problem because my car sits out in the elements. It was a mess but I couldn't help but think of the inconvenience and problems I could have had if it failed while traveling or on vacation. The security of the vehicle was compromised with the rear window completely gone and no alarm when the break occurred. Fortunately I was home and could keep out the elements before I could get it repaired. I feel my dealer did what they could, but I think in this case GM should have done more.
