I drove my (always garaged) Insight to work on a cold morning where the temperature was about 15 degrees when I reached my place of work at 7:20 a.M. I returned to my vehicle, in the parking lot at a little after 12:00 P.M. to find that the rear glass was completely shattered. This is the main rear glass that includes the window defroster and is only available through genuine Honda parts. There is no aftermarket manufacturer of this glass. My parking lot has full time security with cameras in place. No exterior force, other than the environment, had any effect on the malfunction of the car's rear glass. The only thing I can imagine is that the sun heated the cold aluminum hatch at a much faster rate than it heated the glass. This caused the glass to burst and shatter. There was no impact mark like a rock or blunt object might create. But rather there was a fracture all along the perimeter of the glass. Upon contacting Honda, and taking the vehicle to the dealer where all service in the past has been done, they declined, on behalf of Honda usa, to take any responsibility for the defect in the automobile. Therefore, I had to use out of pocket and insurance to take care of this clearly defective part. I took pictures and documented the broken glass. Honda motor company usa should take responsibility for an unsafe and defective rear glass.

The rear hatch window of the Insight "self-destructed" while the vehicle was parked in the garage overnight. The weather had been extremely cold (in the teens), the car had been parked outside all day while at work, and the rear defroster had been used on the commute home. The following morning, the window was found still be in place but was broken around the entire perimeter and the window itself was completely shattered being held in place by the laminate. Through some online research, I tracked down another Insight owner who had reported the exact same problem on "yahoo! groups" two weeks earlier. I contacted him and found that his window had "self-destructed" in the exact same manner after being parked outside in cold weather. I brought my car to the local Honda dealership along with the results of my research and they contacted Honda America. Honda America told the dealer there were no problems with the window that they were aware of and that they consider it normal damage that will have to be paid for (my insurance is covering it). As the Insight is a rather limited production vehicle, the repair parts will take a few days to obtain. For this reason, the current damaged part (window) is still available should an investigation be warranted. I consider this a potential safety issue as there is the possibility for the window to spontaneously break while the car is being driven. Luckily myself and the other owner had our vehicles parked at the time so we did not have any moving vehicle issues. This would appear to be a concern for people with Insight's in cold weather climates.
