I can be driving my car and it will just lose power... I can be sitting at a red light...I can be on the highway and it'll just stop pulling... The check engine light pop on and a wrench light pops on the dash....I have to pull over out of traffic which is extremely dangerous onto the side of the road...I would turn the car off and wait a minute.. Start it back up...the wrench signal is gone but the check engine light is still on...this has been going on with this car for a while now...and I took it to auto zone... They did diagnostics on it and said it was the eit or throttle body.

Driving in city @ 35mph, went to accelerate and nothing happened. Thought engine stalled but still had ps & pb,s. Called local shop, said to turn off & restart. Did and throttle returned. Two days later, happened again, on county highway @ about 60 MPH. Pulled over, turned off, restarted, went to local shop. No check engine light or wrench ?? Light came on. Computer test all negative,but probably a bad electronic throttle body needed @ $ 500. + . Took car and got on line, not going to spend $ until sure of exact issue. Found the federal safety agency csp 13n03 , addressing my identical issue for 2011 fusions & escapes with v6 engines, but haven't found for 2011 mustang. This extends warranty to 150,000, and 10 years. I have 109,879 miles now, and issue happened twice today on interstate @ 75 MPH. Popped to nuetral, killed key, restarted on roll both times.after parking car for short while and restarting, check eng ine lite on. Went back to shop & re-tested, this time, throttle body and associated issues dignosed. Since this is obviously a safety issue that is well documented on other models, I need to have my issue treated equally. What can you do to help?? Humbly, melody & kenneth pitts

6/22/2015: I was driving home from work and my car suddenly turned off and the check engine light turned on. It is very subtle when it happened; no jerky movement noticed. I realized what have happened after my failed attempts to accelerate. I was able to use the car's momentum to make it to a parking lot. I step out and examined my car but nothing was out of the ordinary. After 10 minutes, I attempted to start it up (first attempt after incident) and it started up normally. Everything functioned as normal and even the check engine light is gone. I thought it was a fluke incident so I drove home and forgot about it. 6/30/2015: I was driving on the highway and my engine cut off again. I was very scared because I was on the california 91 freeway and it was during traffic hours. I was able to draw experience from the last incident and cruised my car to the side of the highway. After I examined the car and once again wasn't able to find anything out of the ordinary. I started it back up on the first attempt and the car seemed to be operating normally. I was able to make it home safely but it was a very scary drive home...I will have to bring my car to a dealer and get it check soon and hopefully they will have a fix for this....updated 09/22/15 *bf updated 11/06/2017

11/14/2014 - vehicle engine appeared to stall or shutdown (no power) with "wrench" displayed while exiting highway. Coasted to shoulder and restarted vehicle mileage approx 32,100. Re-occurred on 12/9/2014 while traveling on highway at 70 MPH - was able to coast to shoulder and restart. Ford dealer ran complete diagnostics next day but could not identify a problem. Vehicle mileage less than 33,000. Occurred again on 1/27 on highway while traveling on highway at 65 MPH - coasted to shoulder and plugged in obd-ii diagnostic tool I have been carrying which displayed p2111 throttle actuator control system stuck open. Restarted care - occurred again 2 miles later this time - same code reading - and now check engine light also on. Vehicle mileage 34,650. Dealer replaced throttle actuator control on 1/28/15 at my expense (not under warranty / no manufacturer recall). This is a significant safety hazard - unexpected vehicle shutdown occurring at highway speed.

Driving at normal speeds (45 MPH), suddenly engine light and wrench light both illuminated and simultaneously lost all power to the car. I was almost crushed by a semi truck as I was in the process of turning. I was told by ford dealer to just restart engine and all would be okay. This temporarily fixed the problem but the next day the same issue happened again, this time I caused a large back up of cars behind me causing a very hazardous condition. Now when I talk to ford representative they tell me that it is not under warranty and that I am on my own to fix. After much research, my case is not alone. There is many people with the same situation. Ford fails to recognized that this is a problem.

This began as of last thursday. I have a 2011 ford mustang that I bought just last august. As I was driving on the freeway, a wrench light came on and my car seemed to have stalled on me. I thought maybe it was because it was pouring down raining so I was able to pull over into a parking lot since I was exiting the freeway. I turned off the car after it seemed to vibrate a bit, waited a few moments, turned it back on and it seemed fine. I was able to get home and park it only a few miles from where it happened. I had a doc appointment later that day and was able to get there. It was when I was on my way home that it happened again, on the freeway! It occurred again the next day (friday) as I was leaving from work. I was on the freeway again in busy traffic and it happened twice except the second time, my engine light came on. My dad took it to a mechanic, it was hooked up to the computer and no code came back. Coolant was put in it and the engine light went off. The throttle body was cleaned. Everything was fine afterwards. Today, I'm driving to work and it goes into limp mode twice on the freeway while drivers are swerving around me! This is not safe at all! I have extended warranty on my car so this is going to have to be fixed asap. To anyone else having this problem, please be careful. Once it goes into limp mode, your speed will drastically decrease and you will not be able to accelerate. It is scary because not all parts of the freeway have a shoulder to pull over...this needs to be a recall before someone is seriously hurt. I've read up on other owner's issues and saw that there have been quite a few wrecks behind this.
