Battery Dead problems of the 2005 Ford Mustang

After heavy rain for a couple weeks. I was driving strait, in the rain on a city street. I noticed my radio turned off. Then also noticed my headlights and blinkers were also not working. After reaching my destination before it got too dark I stopped and tested all lights including brake lights. All of the exterior lights weren't working, the gas light came on (although I had atleast a half tank) tcs light and also the emergency brake light were on in the instrument panel. After parking the Mustang in the garage for a couple weeks until I had time to check the status of the car. I noticed the floor of the cab (passenger side) was damp. The car battery was dead (less than a year old, red top optima) and there was mold actually growing in parts of the interior of the car. I did some research regarding this issue and found it common from a failed plug under the windshield wipers next to the a/c filter. Causing the water to fill up between the firewall and the engine compartment, and ultimately leaking inside the cab onto the sjb (Smart junction box) located directly behind the firewall on the passenger side. I am very concerned for this safety issue for it can cause a serious accident if electronics fail while driving and also the fact that there is mold growing in my car from this issue. This is a common problem and needs addressed immediately.

The Mustang battery dies out prematurely. I have had 2 batteries die out in the course of 2. 5 years.

I have experienced complete battery failure twice on my new Ford Mustang. The local Ford dealers service department cannot give me a good explanation as to what is causing this problem. They told me that my car was not being driven enough. This is no answer. They tried to sell me an under the hood power disconnect apparatus. I said no as this would make me reset all of my radio and clock settings every time I disconnected the battery. I don't dare leave my car idle for any length of time as this will probably lead to another power failure. My car only has 1,100 miles on it and it has had to be towed twice to the dealer to have a new battery installed. No new car should have this problem.

Contact states his vehicle will not start. The vehicle has been taken to the dealership 4 times. The 3rd time the dealership replaced the battery this was October 10, 2005. This did not fix the vehicle the battery went dead again. The vehicle was towed to the dealership November 14, 2005 the vehicle is at the dealership as of now. Updated 11/30/2005 -.
