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

Gauges don't work properly. Can't tell how fast you are going, what your oil pressure is, how much fuel you have etc it's a safety issue

The cluster electrical gauge panel has slowly stopped working. First the speedometer started spinning over 360 degrees, then the tachometer went, followed by the temperature gauge, and now intermittently the oil pressure gauge. On-line research suggests this is a frequent issue mainly involving the 2005 mustang year. Ford has refused issue a recall and has declined to fix the problem once the vehicle has passed the warranty period (the issue almost always develops after the warranty period expires). Ford has charged some an exorberent $800 fee to fix the panel. Obviously, it is an issue driving without a speedometer, temperature gauge, and oil pressure gauge (the tachometer nonwithstanding). To have a major electrical system issue in a statisically significant number of vehicles of the same make and same calendar year seems to warrant more integrity on the part of ford in admitting a technical flaw and graciously offering to repair it.

On this day the oil temperature gauge stopped functioning correctly. In the following months the RPM gauge, the fuel level gauge, and speedometer have stopped functioning correctly and read the wrong information.

Tl* the contact owns a 2005 ford mustang gt. The contact stated that while the vehicle was being serviced at a dealer, the technician discovered that the air conditioner emitted a harmful gas into the cabin. As a result, the contact sustained sensations of lightheadedness, severe headaches and heart palpitations that required medical attention. The dealer advised the contact not to activate the air conditioner to avoid further health issues. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 38,200.

Exiting the highway I 93 and entering I 95 s, there is a relative sharp corner to turn. Both my speedometer and tachometer showed incorrect speed and RPM and made me believe I was slowing down to a safe speed of 30 MPH. However these gauges were not working and I was struggling to make the corner. I have had issues with the fuel, oil pressure and water temp gauges not working, but with tachometer and speedometer not working reliable I believe that it is not safe to operate the vehicle. As a precaution, I am using my navigation system to know what actual speed I am going. Looking at the internet, I am finding lots of people complaining about the dial stepper motors not working correctly. It is a costly exchange of approximately $ 600 + labor and with ford knowing of the malfunctioning gauges and not warning consumers is really unacceptable to me. These clusters should be replaced at ford's expense and not at the consumer's. These gauges were designed to ensure safe and proper operation of the vehicle.

I got the car @42,500 or so miles. There was a bad puddle of water after it rained. Near the smart junction box is where it appears to be getting in. I have read alot of complaints online about this issue. For sure a defect that ford should fix... As another person on this site mentioned, I am sure that major electrical damage could potentially take place (I forced myself to cover the car at all times). The gas tank is difficult to fill up all the way. I cannot simply pull the gas pump "trigger" and lock it. The pump stops, due to the trigger being "tripped" (as if the tank was full). So I have to hold down the trigger again (the fuel pump usually gets "triggered" 20 times per every filling of the tank). Super annoying and a known defect that needs a new gas tank to be corrected. How does ford not correct this?
