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.

The contact owns a 2012 Ford Mustang. While installing an amateur radio in the vehicle and driving at various speeds, the contact observed an abnormal noise while the radio was transmitting. The failure recurred on several occasions. The vehicle was taken to a dealer, but was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 45,000.

My 2012 Ford Mustang has been experiencing problems starting with the vehicle in the park position. All of the appropriate lights on the dash come on, but the car will not crank until I place the gear shift lever into the neutral position. This happens with the car parked on level ground and the emergency brakes applied and I have verified that the indicator shows the P for park. After, doing research I have found that Ford recalled some 2012/13 Mustangs for the transmission range sensor (trs) which was not properly calibrated affecting the starter interlock preventing the vehicle from starting until the transmission is placed in neutral. The recall was 12C23, NHTSA # 12V190000, my 2012 Mustang was not included in this recall, but I have the same problem with an improperly calibrated (trs).

On 02-25-2014 at approximately 0800 my wife ([xxx]) was driving our 2012 Ford Mustang GT, she turned on the heated seats and was traveling North bound on ga hwy 49 when the seat warmer malfunctioned overheating and burning a hole through the leather seat back, causing a first degree burn to the bottom left flank of her back. On 02-27-2014 we took our 2012 Ford Mustang GT to riverside Ford/Lincoln in macon, ga we advised them of the incident, they charged us $95 to inspect the electrical system and determine what caused the seat warmer to malfunction and burn a hole through the seat back and cause a first degree burn to my wife's back. Riverside Ford stated the circuit for the seat malfunctioned/failed causing the seat warmer to overheat and burn a hole through the driver's side seat back. Riverside Ford stated our Mustang was out of warranty and we would be responsible for repairing/replace the driver's side seat of our Mustang at a cost to us of $1,142.36 (parts $715.76, labor $350, misc. $26.50, and tax $50.10). I called the Ford customer relationship center (1-800-392-3673) spoke with a representative and opened a case (case #: [xxx]) they stated there were no recalls concerning the seat warmers in the Ford Mustang's and there was nothing they could do for us concerning replacing/repairing the drivers seat in our vehicle but they would be looking into the problem. They did advise us to save our seat when we pay to have it replaced in case there is a recall at a later date. I am glad my wife was not more seriously hurt than she was and that she turned the seat warmer off before the vehicle could have caught on fire while she was driving on the highway and possible causing an accident or harming other motorist around her.

I was driving my 2012 Ford Mustang V6 premium on the morning of 10\21\2013 when for the 4th time the advance traction control malfunctioned. When it malfunctioned the traction control light started to flash and I was unable to steer my car, blower on my air conditioner came on by its self full blast. While I was trying to get control of the vehicle a eighteen wheeler had to go off the interstate into the grass to keep from running my car over! this is not the first time this has happened it has been in the shop 3 other times starting at about 13000 miles. The problem is only getting worse!! I carried it to the shop when it first started having this problem they told me then that the control module was under national back order at it was going to be 6 to 8 weeks before they would have to part in for my car. The dealer was told by tech support to replace my 2012 part with a 2013 part"?" they did that even though the part number was different. The next time I carried the car in the shop for the traction control they keep my car and did nothing.the third time I carried it to the shop for the same thing the tech connected to the car to the computer the alternator sent crazy waves to the electrical system and it messed up the battery they had to change the alternator and the battery. And even with everything they have done the car is still unsafe to drive and they tell me to take the car and when it happens again they will check it again. Now I am stuck with a car that is going to get someone hurt or worse someone killed!!! please help!!!

I had two incidents of unintended acceleration in my 2012 Ford Mustang GT automatic transmission premium pkg. These two incidents occurred on the same day March 5, 2013. The first was after I picked up my car from its garage of several weeks at lunch and drove back to work. I had gone about two blocks from my garage and was braking to slow down to make a right hand turn when the car down shifted and accelerated by itself while I was pressing the brake pedal. I was going about 5 mph when this all started. It lasted for about 3 seconds and then the car released and stopped the acceleration and I was able to slow down and make my right hand turn. I continued on back to work and complained to my co-worker about what had happened and how I was beginning to become afraid of the Mustang. He is my witness about this happening before the second incidence occurred. Later on I left work to go home and on the way home it happened again a second time only this time much stronger. I was in bumper to bumper traffic going under interstate hwy 820 bridge in fort worth to go under the bridge after going through a traffic light on each side to make a left hand turn to get on the West bound IH820. Well because of the traffic you have to stop at one light on the South side of the bridge and then again stop to get through the second light on the North side of the bridge to turn left. Anyway there was a large semi-truck hauling rocks in front of me and I stayed back about 60 feet so as not to get the rocks on new car. He went down to the other light which was red and stopped I was going about 5 mph again and started to brake way back from him because of the rocks and the red light. The car again accelerated on its own while I was pressing the brake pedal. I fought it the whole way but it would not let release till 15 feet from truck. I then crashed. I could have been killed!

Issue # 1 brakes: Upgrade "brembo" brakes squeaked about 2 weeks out the dealership. Took it a total of 4 times and dealer could not find the issue, the 5th time, I drove the vehicle and showed service advisor and tech. According to dealer the rear brakes were replaced. The next day, brakes are still squeaking, take it back to dealer where it was repaired a second time, picked up the car, on the 4th day, I was coming to slowing down ready to brake, pushed the clutch and car jolted forward (as if I pushed the gas and let go of the clutch). I did not think anything of it, 5 minutes later, the car started grinding, noise was only heard when driving and would stop as the vehicle came to a stop. A few days after that I was moving car forward, in my driveway, put in first gear, clutch in, as I slowly released the clutch (never touched the gas), and as I tried to brake, the vehicle did not stop, clutch engaged, pushed the brake as hard as I could the car kept moving as if there was pressure on the gas pedal, ended up hitting our SUV parked in front, car still did not stop, actually pushed SUV about 10 feet forward, until I turned off vehicle and used the hand brake. Issue # 2 A/C - when driving the air would come on randomly, full blast, the screen would show exterior temperature at 00, 2 fans would come on, one on each side of the screen displaying 88 degrees (vehicle is not equipped with dual air controls ). this happens random and in the past 4 months I've had the car I have experienced this issue 3 times. - dealer cannot find the problem.
