Owner reports
Selected complaints filed with NHTSA by 2011 Ford Mustang owners, lightly cleaned up (personal details are redacted by NHTSA).
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". …
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 NHTSA 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. …
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). …
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.
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.
Tl* the contact owns a 2011 Ford Mustang. The contact stated that while driving at various speeds, the check engine warning light illuminated. In addition, the vehicle would suddenly loose power and would not accelerate. The vehicle was taken to the dealer who diagnosed that the fuel throttle body needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 50,000.
2011 Ford Mustang, while driving home from work at 45-50 MPH car shuttered. Then no power, no throttle response with engine holding steady 1100 RPM. Wrench light on dash lit up, RPM at 1100rpm press throttle- no response at all. Steering, brakes all functioning. Turned key off and restarted, car ran fine and has not happened again yet. Car has less than 46000 miles..
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.
My 2011 v6 Ford Mustang has now stalled several times going down the road. Has happened at both high and slower speeds. After pulling over and waiting a few minutes, car starts and runs okay until the next unexpected stall. Repair shop revealed no codes. Very dangerous problem!
