My vehicle defrost was on for the back defroster on my way to work as it was one of the coldest days where I live. I work for the fire department and work 48 hrs on. The second day of my shift one of my coworkers noticed the back window broken out on my jeep. Upon looking at what caused it there is burn marks where the rear defrosters touch the window. I initially called the police but they agreed the window was broken due to the rear defroster wires burning the window causing it to break out. Jeep sent out an engineer and is denying all liability. There are TONS of people reporting this on the jeep forums/blogs. I have pictures to prove the burn marks.
