Wiper problems of the 2007 Toyota 4Runner

Driving along the freeway in winter conditions I used the rear defroster for the back window, this caused the back glass to explode loudly, shattering glass onto belongings, animals and the road behind us. This caused drivers behind us to act evasively and myself as well making a winter driving condition more dangerous, not to mention the spray of glass that reached the back seats of my car with passengers. This has been well documented by other drivers and been acknowledged by Toyota in letters and technician bulletins for replacement of the windows, there are no warning lamps, it just goes from working correctly to exploding.

Parked at a stop light and the rear windshield shattered.

During use of my rear window defroster, the rear window popped and shattered into the interior of the car.

My rear window shattered after using the defroster. Once I got out of my car after parking it in my job's garage it busted on it's own. I found out that this has happened to many 4th generation 4runner owners but Toyota won't recall or extend the warranty for this issue any longer. Now I have to either never use my rear defroster again while living in colorado or risk it shattering again and hurting passengers in my car. I would have never bought the vehicle if I had knowledge of such a dangerous issue.
