The car will "shut down" (wrench error light) at any time, anywhere, any speed. Very dangerous!!! Error code p2111 throttle body actuator stuck open. I have seen numerous posts on this. Ford really needs to fix this!!! I will no longer let my child drive this car. So unsafe!! It happened to me several times a day probably three times in the last week. The vehicle is in motion, highway, city, straight, turns, fast, slow.

So the car has a actuator control system stuck open. I have had it at the ford dealership twice now and will be going back on monday again for the same issue. When it starts up it runs at the 1 RPM then it goes down from there, not letting the car getting any fuel or speed for it to go forward or backwards. I have cleared the codes and works for a few days but then it does it again. This last time the code wouldn't clear off so I was stuck on the side of the road to have it towed to the ford dealership. The code on it is p2111. Just very frustrating knowing that I cant really on my car to get where I need to be. The first time I was in my driveway fixing to go to work when it happened and couldn't get out of my driveway. The second time happened again in my driveway but took it to autozone to clear the codes. And the third time I was driving home from work last night on 01/06/2018 when it stopped my car on the highway in the middle of the night. Just doesn't get any power to the car. My copy of the invoice is in my car which is at the billingsley ford dealership now.

Normal driving on highway, speed around 50 MPH, car abruptly loses power and goes into "limp" mode with flashing wrench light on dash. Car does not respond to throttle and barely moves with rough idle. After stopping and turning car off and restarting, problem is temporarily fixed, but comes back within a few minutes. Cel code is p2111.

While driving my 2011 v6 mustang the car will completely loose power. This has happened on the highway and on side streets. There is no warning. The wrench light comes on and the car is forced to idle. No response at all to throttle input. Error code read is p2111 which indicates "throttle actuator "a" control system - stuck open". It is my understanding that the throttle body in this vehicle is the same as used in other ford vehicles. A recall has been issued for those other vehicles but everyone suffering from this on the v6 mustang is on their own. This can be very dangerous for people accelerating to merge and very dangerous on the highway to stop in the middle of the road or have to limp to the shoulder through traffic at idle. I have already paid $300 for a full throttle body service and the same thing is still happening.

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.

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

While driving down the left lane of the sawgrass expressway, a very busy highway between ft. Lauderdale and miami, I lost all throttle response. The wrench light came on the dashboard and I went from 60 MPH down to nothing by the time I was off to the side of the road. Cars behind me were obviously braking hard to avoid smashing into me. I turned the car off and was about to call aaa, but the heat index that day was around a million degrees so I turned the car back on. The throttle response had returned so I cautiously limped the car back home in the right hand lane the whole way. I thought it was some freak computer glitch until it happened again going to the store the next day. I called the ford dealership and before I even got the problem oout of my mouth the service tech said " it is your throttle body. We see this all the time. It will be about $800 to repair". If the techs are aware of this problem and it is all over the internet with people complaining about dangerous situations the have been placed in as a result, and there is already a recall for the same problem in other ford models, then why hasn't the federal safety agency done anything to force ford to recall for the same problem on the mustang? Does someone have to die first? Has somebody died because of this?
