The wiring for the rear defrost caught fire. A week later it caused the rear glass to completely shatter. We didn't know it was the rear defrost wiring until we had the glass replaced and were able to see the wires fried. I have farm animals and routinely leave my 3 children in their carseats in the truck with it running when it's cold outside and I feed our animals. If it had caught fire with my kids in the truck I wouldn't have known and they wouldn't have been able to get out. I talked to 2 Ford dealerships, 2 different lawyers and a service rep through Ford's website. Even though this exact issue is everywhere on Ford Forums no one will do anything about it because there's no current recall. The only thing we could do to make sure this doesn't happen again is to pull the fuse for the rear defrost. This is a devastating accident waiting to happen and no one will do anything about it.
