Horn Assembly problems of the 2009 Ford Mustang

I have experienced problems with sensor faults prior to the first incident. Around may 22 I started experiencing water leaking under my dash board first when I thru a cawash. Then it rained and water came again. The tire pressure fault again came on and I was over due for an oil change so I took it in to have it looked at. The tech advised me to get the extended warranty and advised me the leak was a defrost evaporator and the tire pressure sensor was bad and would not be covered by warranty if extended. He said I needed to set up an appointment with the water damage guy to clean up the mildew and mold damage to the car which would cost 400 not to mention other parts and labor. So I was under the understanding that as long as I didnt use the defrost evaporator the leak would be contained. So I used it only on sundays and one Thursday from may 22 to July and had only put about 700 miles on the car. The week of July 19th we had a ton of rain and I noticed the floor board was saturated with water and the humidity in the cabin made the panels on the doors start to peel away and there was condensation on the inside of my windows and dash. So I sopped the water up with multiple towels. I was very frustrated at the time and was worried about how I would handle myself at the dealer. That night at 235 am on July 19th a police officer advised me that a neighbor had called about an alarm going off and that they saw what appeared to be smoke coming from the hood. So I couldnt get my alarm device to work and started the car thinking it would stop. Well it didnt, so the sheriff and I agreed to disconnect the battery for the car was experiencing an electrical short which triggered my horn. As I got to the hood you could smell fried wiring but I didnt see any smoke myself. With these cars from 2005 why isnt this a recall, does it have to cost a life to make a change?.
