Electrical Failure Problems of Ford Mustang

There is a manufacturer's defect that allows water leakage into the instrument panel/Smart box junction and subsequently into the vehicle itself. Resultant issues include the inability to drive the vehicle (frozen shift), electrical failure with loss of instruments including various gauges, brake lights, ventilation/ac, power windows, and headlights, and physical water damage (mold/mildew). Ford is aware of the defect and later models were redesigned to compensate for the flaw. However, Ford refuses to issue a recall or acknowledge the deficiency, nor will they provide any kind of financial assistance with the necessary repairs directly caused by this defect. Should the Mustang experience the above mentioned electrical failures while being driven, an accident could occur. There are numerous similar incidents reported about this exact same issue, and Ford must be held accountable. I spoke to Ford "customer service" on 5/5/11 to report the issue and request financial assistance for the repairs. I was told to take my vehicle to the dealership, pay for the diagnostic test, and have the dealership confirm the "defect". I made a follow-up call to Ford "customer service" on 5/9/10 to report that the service manager did confirm the defect and that he had seen similar problems. However, Ford said they were not responsible, would not provide financial assistance, and that I was "misinformed" by my initial call to Ford in giving me hope they could somehow help me. Additionally, they stated that I "should not expect my Ford vehicle to last beyond 100k miles". In the meantime, we are responsible for the towing, diagnostic, and repair bills, so the Ford service department is profiting from this. This was our fourth Ford vehicle, and it will certainly be our last.

The contact owns a 2005 Ford Mustang gt. The contact was driving 40 mph in heavy rain when the entire electrical system failed without warning, including the lights and dashboard gauges. The contact continued to drive with caution to a nearby service station. The engine was turned off and restarted after five minutes. The vehicle resumed normal operation until the failure recurred within twelve miles. The dealer was notified and informed the contact that the failure would be difficult to diagnose since the vehicle was operating properly. The failure mileage was approximately 66,200. Updated 01/14/11 updated 03/28/11.

The contact owns a 2006 Ford Mustang. While driving approximately 10 mph on wet road conditions, the vehicle came to a stop sign and then proceeded to accelerate. Suddenly, the contact heard water coming from the front passenger side of the vehicle. The contact pulled over to the side of the road and the driver observed that the passenger floor panel area and the glove compartment exhibited water leakage. The vehicle resumed normal operation to his residence. The following day, the engine failed to start. The vehicle was towed to the authorized dealer for diagnostic testing and they stated that the failure was contributed to an electrical shortage in the junction box. The technician stated that this was a manufacturer design flaw with the drainage. A fan was used to dry out the junction box; however, the electrical failures still persist. The exterior components that were inoperative consist taillights, parking lights, emergency brake lights, turn signals, rear back up lights, and the low beams. The VIN was unknown. The failure and current mileages were 52,000.

While driving in light rain, I experienced a total failure of my electrical system, including headlights, door locks, interior lights, radio, trunk release, etc. At that point, all warning indicators lit up on dash. I pulled over, put the car in "park" only to discover that, while the electrical issues continued, I couldn't get the car out of "park". After ~ 10 minutes the electric systems came back online, but the "check engine" light remained on. After taking the car to the dealership, I was told the problem was a water leak. There are numerous posts about this issue online, but the dealership claimed to have never heard of it before and refused to fix it free of charge, despite the fact that it's a manufacturer's defect. This could cause a serious problem if the problem occurs while driving at night, when loss of headlights could have catastrophic consequences.

: the contact stated while driving 3 mph at night in the rain, the entire electrical system failed, except for the center brake light. All the lights, the radio , the outlets, and the electric windows failed simultaneously. This was accompanied by all the engine warning lights on the dashboard illuminating, as well as the digital readout giving warning messages. The contact depressed the brake, and everything worked again. The battery was disconnected briefly, which made everything function intermittently upon reconnecting it. The battery was disconnected a second time for a few hours, which fixed the problem. The vehicle was not seen by a dealer.
