When it rains, water is leaking under the windshield into the duct work and onto the passenger side floor. Heavy rains have caused as much as 5 inches of water to lay on passenger floor. This problem has caused the smart junction box to malfunction and car is not drivable. I now have to purchase a new box and have it programmed, which is very expensive. I have read articles about this happening to other 2009 Mustangs. Ford has no recall on this issue. Not only is it expensive to fix, it also is a safety concern because it can cause an electrical fire to ignite within the car. This issue happens when the car is in motion and stationary.

Takata recall my 2009 Mustang has a defective passenger seat occupancy sensor. When no one is seated the airbag flashes code 16. When I fasten the belt on that side still unoccupied, the fault code stops, but the center dash lights up indicating passenger airbag is off. My research shows the problem is not unique to my car, and that it has and is an ongoing issue with many cars not just Ford. This vehicle is on the takata recall for drivers airbag replacement since March of 2015. As yet Ford does not have replacement parts. I believe the passenger seat cushion assembly which includes the bladder, sensor, and ECM should also be recalled. I live in Hawaii (high humidity) and research has shown this to be the root cause of the failures. At this point the vehicle is completely unsafe for the driver and passenger in the event of an accident, the drivers airbag has the potential to cause serious injury or death, and the passenger airbag may or may not deploy or effectively prevent injury or death. Please respond with any direction.

The complaint filed by phone on 9/15/21 id #10763956 included important facts that are not showing on your web page. The damage to the electronic module was caused by the water leak as referenced in Ford's tsb 08-26-7 and I also filed complaint with Ford consumer relation since they offered no relief. I was unaware of this issue and consequence but, I'm now finding it's nothing new for owners as well as the auto industry that this is a problem with Mustangs '05-'09 and the resulting damage to the generic electronic module happens often.

The contact owns a 2009 Ford Mustang. While the vehicle was parked, the contact noticed water dripping from the front passenger side glove box. In addition, the head lamps, interior lighting, driver side turn signal, and hazard lights illuminated independently. The vehicle was taken to an independent mechanic who diagnosed that the generic electronic module needed to be replaced. The vehicle was not repaired due to parts being unavailable. The manufacturer was not notified of the failure. The failure mileage was 40,000.

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?

The check engine light. My vehicle (which I purchased new in June 2010) has been to the Ford dealer seven time in an attempt to repair an on-going problem with the check engine light. The Ford tech's have determined that there is a problem with the fuel recovery system however they are unable to repair. I have not driven my vehicle since I picked it up the end of Jan. 2011 and the check engine light came on 100 miles from the dealership. I have determined that there is either a problem with the fuel recovery system as the Ford tech's. say the light indicates or there is a electrical problem with the indicator light. Either or of which could cause a fire in my vehicle. I'm a fire investigator and it has been my experience that most accidental vehicle fires are caused by fuel or electrical problems.
