Check Engine Light On problems of the 2011 Ford Mustang

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.

11/14/2014 - vehicle engine appeared to stall or shutdown (no power) with "wrench" displayed while exiting highway. Coasted to shoulder and restarted vehicle 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 travling 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.

Vehicle experienced sudden and unexpected loss of engine throttle sometimes in high-speed situations, activation of limp home mode, check engine light, and engine malfunction indicator. Diagnostic code reported failure of electronic throttle body, code dtc p2111. Dealer confirmed electronic throttle body assembly fault basic part 9f991 and replaced, extremely similar to NHTSA investigation pe13-003.

While driving my 2011 Ford Mustang down the road the check engine light and the wrench light came on and lost all power, the engine never died but would only idle very rough. I took it to have the code read out, it showed a code p2111 throttle body actuator wide open. It has done the same thing 2 times today. Once you pull over and cut the engine off then restart it will run fine, but not for long before doing the same thing again. I got online to see what the code p2111 means, to my surprise this seems to be a big problem on Mustangs, escapes, and fusions. Ford has issued an extended warranty on certain throttle bodies. This could potentially be a serious safety problem loosing power while driving down the high way.

In the middle of driving down the road, all of a sudden I lose power to the gas pedal and the wrench light comes on. I pull over and put it in park, it makes a horrible racket when in idle. So I have to turn the car off and back on. Sometimes it's okay for the rest of the day and other times it's not even a mile down the road and it's doing the same thing again. . . I checked to see if there were any recalls with the Ford company, and there were none. . . My check engine light has since come on and now I know for sure that it's the throttle actuator motor. . . Looks like there have been quite a few complaints of the same thing! I definitely think there should be a recall on this part!!.

The contact owns a 2011 Ford Mustang gt. The contact stated that the check engine light was illuminated. The vehicle was taken to the dealer who diagnosed that the vehicle had a defective after market programmer and as a result, the engine exhibited an internal motor failure. The manufacturer was made aware of the failure but did not offer any assistance and voided the warranty. The VIN was not available and the vehicle was not repaired. The failure and current mileage was 7, 800.
