Since I've bought this vehicle brand new I have had random issues with the car. First I've experienced a huge issue with the transmission, it makes a vibrating/shaking problem while driving on any street any speed. I have operated manual transmissions before and have never ran across this. No matter what gear or what condition it consistently does this. Ford dealer was to no help at all. At times while driving the vehicle will start to uncontrollably swerve and the traction control light starts blinking, this issue is unknown to me why this happens and has almost put me in an accident. Secondly, the entire ignition tumbler just popped out. I can pull the ignition out of the steering column.

Warranty ended at 60,000.
Ford refusing to accept recall for car; car has issue with transmission lead frame. The car will be driving and will "hard shift" randomly. The speedometer goes crazy and I have to slow down or turn off the car for it to go away. Recall exists for my models transmission lead frame ( I believe I meet all the requirements ) issued in april 2016, but it is not appearing for the VIN of the vehicle. If I do not meet the requirements it should be extended for my car.

2012 mustang only has 35,000 miles and water pump went out. Dealer states it is not covered under power train warranty! Luckily it went out while parked in the garage at home and not on a trip! Antifreeze was every where when I went to get in the car the next morning. Thankfully I saw it before our pets did!

You should know that the 2012 mustang has a defective part called a throttle body sensor. Ford is aware it is defective because they were replacing this part free of charge prior to january 2015. Currently it is not under a safety recall but it most certainly should be. When you drive a car with this defect your can an accelerate, or decelerate, at its own will. It does not respond to the commands the driver gives. It just suddenly slows or speeds up as it likes. If you have not experienced this it may be hard to understand how unsafe this can be. It is not nan experience I recommend to anyone. Ford does not consider this a problem, but I do not feel safe in my car as a result. Try tooling along I-95 at 65 miles per hour and having your car suddenly slow and shudder almost to a stop...fun times. This defect creates an unsafe driving condition that 100% unacceptable and you really should do something about it before someone, (like me) gets killed. I am sure someone has already had accidents because of this issue.
My car has gone into 'limp' mode several times over the past couple of days. I took it to the dealer who advised me that the issue is the electronic throttle body, and it's not covered under the powertrain warranty. This part has been recalled for several other ford model vehicles - but not the mustang and they won't cover it. It'll cost me $570 to get the part replaced in my vehicle. This occurs while driving - at all different speeds - including going 65+ miles per hour on the highway.

I was driving down the street and when I shifted from 1st to 2nd the gear shifter got hung up and would not shift causing the car to downshift throwing me foward and hitting my head on the steering wheel.
After waiting at a light in the left turn lane, I started accelerating from a complete stop, slowly into my left turn. At almost completion of the turn, my tachometer went from 3000 rpms to over 6000 rpms. The car had a sudden jolt at this moment and the rear wheels locked up. I went into a slide and the car slid across 2 lanes into a tree filled median. The car was totaled by the insurance company. There were no factors that could influence such a crash, as the road was dry, it hadn't rained. The road was well paved. Finally, speed wasn't a factor in the crash. At the time of the accident we had no idea what could have caused the downshifts in gears, however after a recent recall we realized what had happened.
While driving car suddenly loses power and shows wrench light and goes into limp mode. Trouble codes shown p2111 and p2112. This can happen any time during driving and has happened in heavy traffic potentially dangerous consequences.
During initial acceleration after a left turn, shifting from 1st into 2nd gear, the vehicle shook wildly and violently rocked side to side and lost power. This was the second identical occurrence on city streets while accelerating out of left turns. On both occasions, had to make immediate moves to the right lane before power was restored. Based on other reporting and research, it appears to be an issue of throttle body failure. The vehicle has 18,500 miles and has a mt-82 transmission.
Tl* the contact owns a 2012 ford mustang. While the gear shifter was shifted into the neutral position, the front driver seat was lifted and collided with the parking brake. As a result, the parking brake was disengaged, the vehicle rolled away in the forward direction, and crashed into a fence. There were no injuries and a police report was not filed. The vehicle was not diagnosed nor repaired. The manufacturer was not notified of the failure. The failure mileage was 86,000.
While accelerating to get on the freeway, the transmission began to slip and the car began to jerk, then the transmission locked into 3rd gear, and would not shift out of 3rd gear until the vehicle was completely stopped, and the engine turned completely off. This is an intermittent problem, but an extremely dangerous one when it occurs. The ford dealership says I need a recall notice before they can fix it. I'm out of work and don't have the funds to replace or repair the vehicle. Right now, we are driving it as little as possible.
I have a 2012 mustang gt with 6 speed manual transmission. I bought the car as a certified pre-owned car at about 2,500 miles. The car at that point had a dealer re-built transmission and my understanding is that it has 2nd through 6th gear replaced due to a manufacturers defect. Since that time I've had multiple transmission issues and the car now has about 49,000 miles. In early january, it became almost impossible to shift the car into 1st gear. It was very stiff and took a lot of force to get it into 1st. Shifting to 2nd gear resulted in a gear-mashing sound. 3rd gear sounded like a loud clunk. 4th through 6th gears were fine. These incidents became worse and almost caused me to have 2 different accidents by not being able to shift gears in traffic. I took the car to a ford dealership in the north atlanta, ga area and they looked at the car. Their transmission tech believed it was an issue with the synchronizers. The tech did not believe he had the expertise to work on this issue and referred me to another ford dealership. On 1/14/16 I took the car to the 2nd dealership and their tech agreed it was the synchronizers. That dealership took about 1 week to complete the repairs. After the repairs, the issue was not solved; loud sounds were coming out of the rear of the car. Over the past 2 weeks, they've ordered numerous replacement parts. As of today, 2/9/16, there are parts that are not available and are on national back order. The eta for the parts is now 2/24/16. I've read about similar issues other mustang owners with this specific 6 speed transmission have had and personally can say it is a major safety warning for the driver. These cars should be recalled and new transmissions inserted as a whole unit vs. Installing multiple parts. I also believe that this issue will cause me to experience diminished value at resale.
My vehicle constantly goes into limp home mode while driving. Turns off all cylinders except 1 which let's you drive about 5mph. Also while my vehicle is at idle it begins to loose proper idle RPM and nearly stalls until revs back to a higher RPM. After some research I found that the issue is thought to be the throttle body and throttle body sensor. Currently mymy vehicle is at the dealership going through some vehicle diagnostics to figure out the exact problem. They told me it is not covered under the vehicle warranty and I am being charged $145.00 for the initial inspection and then charged by the hour to fix the problem, I not including parts. My vehicle only has 59,000 miles on it and it's already failing. It appears that numerous people are have this issue and ford has yet to recall affected vehicles.
Was driving around 50mph on city streets when all of a sudden car lost power and went limp. Wrench light came on and car was making a weird noise under the hood like it was struggling. Couldn't accelerate and I had to coast to the right hand side of the road. Turned the car off and then back on and everything was okay. This has happened 3 times since within a 8 month time period driving at various speeds. Each time I turn the car on & off again and it seems to reset. I've noticed my car hasn't been getting the same city mpg as before. Ive only had this car 2 years, I'm the second owner and this started at roughly 62,000 miles.
My car has approximately 31000 miles on it. I"m the second owner of this vehicle. 18 days ago antifreeze was on my garage floor. My mechanic come over and explained to me that my water pump had gone bad. So I took my car to the dealership and they told me that it was still was under power train warranty. They diagnosed my car and verified that it was indeed the water pump and that there was another person that was waiting ahead of me for the same thing 30 days. I called other dealerships and they too were out of water pumps. My concern is that I will have to keep buying anti freeze every other day and I cannot afford this. This dealer ship told me that they did not have a loaner vehicle for me. Please help. Thank you.
Tl* the contact owns a 2012 ford mustang. While driving at various speeds, the vehicle lost power. In addition, the gear shifter was difficult to shift into various positions. The failure recurred on numerous occasions. The vehicle was taken to multiple dealers who were unable to diagnose or repair the vehicle. The manufacturer was notified of the failure. The failure mileage was 50,000.
I took my 2012 ford mustang (62,000 miles) to a ford dealer to have the oil changed. They talked me into a transmission fluid change, because it would "extend the life of my vehicle". When I picked it up, it was not running right. The wrench light came on and the transmission was making a very loud noise. I had to have it towed back to the dealer. They replaced some sensors and sent me on my way. I made it home but the car wouldn't start the next morning. To make a long story short, after them attempting to fix it 3 times and it still not being fixed, they finally replaced the power train control module. I picked up the car and it still making a loud noise changing from 1st to 2nd gear. I see that there has been a recall on some 2012 mustangs for a power train control module. I was never notified of this recall.
On multiple occasions while shifting into a higher gear at 7000 - 7500 RPM the clutch peddle did not return to the fully engaged position and the clutch did not fully engage. After driving 1 or 2 miles the situation corrected itself. Manual 6 speed manual transmission and 5.0l v-8 engine. Boss 302 model. Several phone contacts with ford and ford racing resulted in their indication of no knowledge of the clutch sticking problem. 2 ford dealers I spoke to also claimed to know nothing about this situation.
Open leaving work for the day my second gear synco in my transmission completely failed leaving the parking lot. Therefore I no longer had 2nd gear. So I took it to a ford dealer where they where to fix the problem but in turned fix 2nd gear but messed up my reverse synco gear now. The car has been in the shop for almost 4 weeks and ford wont make a surplus of part for this transmission that the parts needed are on back order until april 20th 2015.
As I was trying to put my car into 3rd gear it wouldn't go into gear. So I have to slow down in order to put it in 2nd gear. Another time I had to go into 4th. This is very concerning to me.
Driving down the highway full speed in heavy traffic, and engine just shuts down. Wrench light and check engine light come on. Have to coast through traffic to pull off to the side of the road and stop. Restart the car a couple of times, and then it's fine. Took to ford dealer, who said I had a bad throttle body. Charged over $800 to repair. Completely losing power while driving down the highway is definitely a safety issue! Ford has agreed to fix defective throttle bodies on other models, but not the mustang. This really looks like the same problem, and should be addressed by ford.
On oct 30, 2014 I was shifting to 2nd gear and the engine bucked, lost speed, then the "wrench" symbol illuminated, indicating the limp home mode activated. I pulled into a parking lot, shut off the engine and restarted it and the light went out. I drove it to an auto shop and they could not detect a malfunction code. Today, nov 5, 2014 when leaving my neighborhood, the same loss of speed occurred in 2nd gear and the wrench and check engine light came on. I drove back to the local auto shop and they determined the throttle body was defective. The solenoid was bad. Fortunately, my incidents happened at a low speed. This could be catastrophic at high speed, running the risk of a high-speed, rear-end collision.
Today while trying to accelerate at a intersection and shift from 1st to 2nd gear the transmission wouldn't let me into 2nd. Now if this just happened once I would let it go but this has happened several times. This is a big safety issue considering it causes my car to slow while I'm trying to get into gear with traffic coming at me. This needs to be resolved before someone dies. I'm not the only person who has complained about this issue.
