Takata recall I been dealing with a electrical problem with my car and its brand new. Every time I get in the car and turn it on and drive for about 5 minutes my music turns off and shows the horse symbol displayed on the screen and it comes back on 10 minutes later. But then sometimes it does that and then the display screen turns black and I can't turn on the radio or anything. And that last for a few hours or so. . It's really getting annoying and something needs to be done.

On 8/18/16, I was driving on maryland state route 198, at about 40 mph, when the car began to lurch forward, stop, lurch forward as I came through a roundabout. I pulled over to the shoulder. I turned the car off, restarted the car, and while on the shoulder, I pressed the gas pedal, and again the car lurched forward twice and then stopped. Wrench light was lit up on dashboard (it wasn't lit moments before) and when I looked at the manual it said the car had defaulted to "limp to home" and I should see the dealer. I was more than 40 miles from home and called aaa. If this had occurred 10 minutes later, I would have been driving 55 mph on interstate 295 s and would have been in danger because that road has no shoulder. This car behavior mimicked what I experienced oct. 6, 2015 (lurching, dashboard lights looking like a disco ball), when the dealer had to replace the throttle assembly (service date oct. 7, 2015). However, the dealer is now telling me it is a transmission problem with the car showing tft sensor, p0710, p0713 code readings. This is the third major repair. On 11/23/12, the dealer replaced the instrument cluster, after I experienced an issue thanksgiving day with all dashboard lights looking like a disco ball and could not read the speedometer to know how fast I was driving while in baltimore on interstate 695. The car is 4 years old and has about 61,000 miles on it. I believe all three incidents represent safety issues. I did not know you could file a complaint until I began researching after this latest incident, and so include the the other two in this report.

I was driving on the freeway going 60mph when all of a sudden my cars power just cut off and it went into limp mode and had the worst idle at 1100 rpm until I turned off the vehicle. I then turned it back on and the limp mode light went away but a few more miles up it cut power again and almost caused a wreck as I had to quickly think and get to the side of the freeway. It happened 2 more times that day til I got it home and got the engine code p2111. I found out later its a faulty throttle body that they used in fusions and other models and everyone is having this same issue of it randomly cutting off. It's a faulty throttle body that should be recalled!.

The car was in motion going down the interstate about 70 mph. All of the sudden the car speed dropped slowly until it reached about 20 mph with the gas pedal all the way to the floor and it would not pick speed back up. The service light came on and I pulled over. When the gas pedal was pushed while the car was in park it would not rev at all. Once the car was back in motion it would not go over 15mph. After the car was turned off and the battery reset the car was working like normal for a few days. Once again driving down the interstate out of nowhere the service light came on and the cars speed declined once again, once the car was turned off and reset it worked fine. This problem keeps happening with no warning.

For about 3 years, constant problem with water leaking onto my passenger floor board. I have to put plastic bags outside the windshield underneath the wipers every time it rains. This doesn't keep all the rain from coming in but it helps. I can no longer go through a car wash because it floods the inside of my car. I now have a plastic bucket on the passenger floor board in case it rains while I am driving so the interior doesn't get flooded. There is now a mildew smell in my car. There have been many complaints about this so it is ridiculous that we consumers have to foot the bill for an issue that Ford has known about for a long time. The last time I checked with a dealer a few years ago they said it would cost approx. $800-900 to try to fix; I'm sure some people have an extra grand laying around but I sure don't. Ford needs to issue a recall on this issue!! it is a safety as well as a health hazard, especially if people have small children. I am the second owner of the car and it started at about 70,000 miles.

My engine has randomly shut off three separate times now. I have about 12,000 miles on mt 2015 Mustang gt w/pp manual transmission. The first time I was parked and it was idling, my friend and I both witnessed the idle dip, then 3-5 seconds later the engine shut off. The second time (was much more dangerous) I was changing lanes because of a car fast approaching from behind, I downshifted from 3rd to 2nd gear (30-40mph), let out the clutch smoothly, pressed the accelerator and the car did nothing, I looked down and the rpm was at 0 and "press clutch to start" was displayed on the gauge cluster screen. I quickly depressed clutch and restarted engine and took off to avoid an accident. The third time happened today 3/15/2016 I was again at idle and the engine just shut down without me touching anything, it again displayed "press clutch to start". I've read in forums that many people are having this issue intermittently, this could be a serious safety issue that can have deadly consequences. Please address this issue correctly rather than sending everyone home with the "we didn't find any issue" go-to response. Hopefully people don't have to get injured, or god forbid die, before this issue is taken seriously.

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...

Failure Date: 01/06/2016

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.

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.
