Software problems of the 2016 Ford Expedition

The vehicle blower speed controller doesn't match setting on the clement control. The blower will blow at full speed or not at all. This happens not matter the disposition to the vehicle. I took this in while under warranty, nothing was found. Second time out of warranty, stated it was a software update that was needed. Third time they found the issue with the speed control and the wire harness had melted (potential fire issues). Now that the issue was found, palm coast Ford refuses to fix it under warranty. On searching most common issues with the Ford Expedition I have found that the blower speed control is an issue for many people. From personal finding, it is a fire hazard, which makes it a safety hazard. I had mentioned it to the dealership since I bought the vehicle. When it got more common of an issue and more annoying, I took it in while still under warranty to have it documented.
