Failure Date: 02/03/2016

My back passenger floor is soaking wet for no reason. I have had issues with my air conditioning. Dealership said I had a leak but could not find the problem. I researched when they couldn't find it. My car started to not only blow hot air, but started smelling moldy. My cabin air filter and the carpartment was full of water. The filter was soaking wet and full of mold. I change it and drained the water myself. My car ac ran better than ever up to yesterday. My ac is not blowing the ice cold air and their is lots of water on the back floor. I have heated seats. The electrical parts are under the seats. I was told by the dealership I have the best warranty but it doesn't cover water. It didn't cover the ac either. I'm told I'm going to have to pay another $300+ to fix my car when this is a problem with 2005- present Mustangs. . Read more...

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.

Car was parked in my driveway and after a rain storm I noticed the passenger floor was soaked with water. Water leaks in from the cabin air filter and drips onto the fuse junction box on the passenger side of the car. When drain holes in cowl gets clogged water builds up and then pours in the cabin filter then into passenger side flooding carpet. As water drips down it makes contact with the f j b and starts to mess with the electrical parts, ie power windows go up and down by themselves, dash light won't shut off, radio will not turn off and convertible roof keeps trying to go up and down. Only fix is to replace and reprogram the fjb but Ford no longer makes this part because of the known issues. I am told either to wait for replacement unit to be developed or buy a used one and hope it will work either way still have to pay $400. 00 for part and $250. 00 for reprogramming. This is a known problem that is being passed onto the consumer . This has happened to not 1 but both of my Mustangs 2005 and 2007 , same style with same problems.

Failure Date: 10/17/2015

For a while now I have been experiencing after rain - water flowing through the passenger side firewall and along the passenger side kick board where the Smart conjunction box (fuse box) is. I have taken it to a Ford dealer who said he didn't know what I was talking about and would be $95. 00 to start looking in to what the problem is. This past Saturday, I parked my vehicle the key was stuck in the ignition and the car will not shift out of park. After searching online it seems this issue can be directly related to water damage. Water seeping in to the fuse box. I also found online where there are a number of model years that have had this issue. Now I am going to be stuck with a gigantic repair bill for a design flaw that Ford knows about and could of issued a recall for.

This 2005 Mustang was bought used about a year and a half ago. Within a few months we noticed the messenger side floor would be wet when it rained. Soon after the speedometer quit working. The extended warranty did not cover the repair. A few months later the heat and air control unit went out. These two repairs cost over a thousand dollars to fix. On October 102015 while at the drive up teller at a bank the car would not come out of park. Tried shutting it off but would not restart. Seemed to have complete electrical failure. No lights gauges or anything electrical would work. It was raining. After jumping the car several times we were able to get it home. We inspected the ecu and found green and white corrosion indicating water had been getting inside the box. When I called Ford they took a report but said they would not fix the problem unless there was a recall. There is a technical service bulletin issued TSB 07-14-6.

With no warning the electronic throttle body will fail causing the car to rapidly decelerate to its idle speed. In my case it happened on a city street in heavy traffic while the car was in motion. The motorist behind me almost rear-ended my car, and several other had to come to a screeching halt. The problem is dangerous, since it can occur at any time in traffic. It continued to happen after turning the engine off and back on. Since the issue is known in other Ford vehicles of the same model year range, the company should be communicating the issue to customers and proactively replacing the faulty part.

I was driving in the expressway at 60 mph when suddenly my car lost power on the acceleration. A wrench tool appear and the dashboard on the rpm clock . . . At that moment the car desaccelerate almost to 30 mph and I was unable to gain speed. I went to a side of the road, turn it off and restarted the car. Everything appear to be normal but the first thing I did was go to the dealer. They run a test on it and told me that the problem was related to the electeic throttle body. I dont understand how is possible to happend something like that when my car barely has 4 years. There is no warranty on ot and the repair for it is really expensive.

Driving down an interstate a wrench came on the dashboard and car went into limp mode. Pulled off turned the car off and restarted it. Got to the destination ok but on the way back home the wrench came on again. Looked at the code and saw it was the p2111 code. It happened 4 times in the way, losing power and shaking. Taking it to Ford tomorrow to find out if it covered under the warranty. There was no recall in the car,however, I am noticing a lot of people are having this issue. This is a safety issue and should have a recall on it. From what everyone else is saying Ford is not doing anything to help or fix the problem.

I am the owner of a 2015 Mustang gt with cooled seat option. When I purchased the car new in November of 2014 and tried the cooled seats they worked well during those cold late fall days for the handful of times I used it. After it got cold during winter and spring I did not use the cooled seat feature again until approximately may 1, 2015. At this time the lower seat cooler would cool the seat but the upper seat cooler would not cool the seat for any amount of time. In fact quite the opposite occurred. With the seat cooling set to maximum of 3 bars the lower cooler would get the seat cold but the upper seat cooler would actually warm the seat up. Several tests confirmed this happening for both seats, driver and passenger. Due to the design of the thermoelectric device buried and enclosed in the seat back, the back side of each seat back would actually warm as well to levels very hot to touch after as short of time of 5 minutes of use. It appears that many other 2015 Mustang owners with this option are experiencing the same issues. Also 2015 Ford f150 owners who have the same design ted cooling device are experiencing this as well. I have contacted Ford customer service and registered my complaint but no fix is out there currently from Ford this is obviously a faulty design. Its equivalent would be putting a room air conditioner inside a room and expecting it to cool the air. On top of that with prolonged usage the material on the back of the seat where the ted vents its waste heat gets hotter and hotter and could pose a fire risk with prolonged usage in the vehicle. Currently we have no information whether or not Ford is either aware or even has any intention of addressing this issue I do not use my cooled seats function currently because it only works on the bottoms and heats us the upper seat while in use. The upper seat will actually be cooler if left off.

Driving up hill going about 20. Orange wrench icon comes on and I lose all acceleration. Had to pull over going up a hill losing acceleration fast when cars are parked on the side of the road. Barely made it to a turn and parked my car. Had to turn the car off and wait a minute and turn it back on. Turned around and went home. Called Ford dealership and asked what could be the issue. The mechanic said it could be one of two things. Took the car in to get a dtc code and they couldn't find it. The mechanic said it was safe to drive. 4 days later the same thing happened going 60. Had to pull over and restart the ignition. Almost got rear ended. Took it to the dealer again. No code. They tell me it is safe to drive still. Three days later it happens again on the same road going 60. Certain part of this road have no place to pull over. Have to drift my car for a bit to get to a safe area. Almost get rear ended. Call dealership. They tell me the earliest they can see me is one week away. This morning on the way to work it craps out on me 5 times in 20 minutes. Luckily it was 5 am and there were few people on the road. I do the same thing and restart the car. I used my tuner this time and got a code of p2111 - throttle body actuator code. I know this has been an issue with other Fords as well and checking the message boards for the Mustangs and I have seen quite a few of these incidents, but I did not see where the NHTSA was looking at the Mustangs. Maybe this should be looked into before a lawsuit happens because of this? this car is not safe to drive no matter what they tell me. I will call the dealership this morning and give them the code so they can finally fix my car.
