Vehicle has less than one year since it broke down last and now I have another problem. The secondary timing chain tensioner has failed and lead to secondary timing chain failure broken rocker arm and maybe damage to the piston it has been problem after problem this car is a lemon and this needs to be addressed I was driving through and intersection and my car stalled luckily it started once more just long enough to get it off the busy road. There was bolts on the valve cover that's weren't even drilled through the plastic valve cover. There is no reason a fairly new motor should have malfunctioned like this.

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.

While driving at 40 mph the car lost power and was only able to move at about 2-3 mph. A 'wrench' warning light came on. Driving the car at this speed was unsafe and in hind sight I should have parked it and towed to a dealer.

While driving with cruise control set at 55 mph, car began to decelerate, yellow "wrench" advisory light illuminated and engine appeared to be running rough. Car slowed to a stop and I pulled the car off the roadway. I switched off the ignition and waited approximately 30 seconds. I restarted the car. The advisory light stayed off and the engine ran normally thereafter. When the incident occurred, the car was on a highway curving turn to the right. The incident occurred coming out of the curve.

I was driving on the freeway going 60mph when all of a sudden my cars power just cut off and it went into limp mode and had the worst idle at 1100 RPM until I turned off the vehicle. I then turned it back on and the limp mode light went away but a few more miles up it cut power again and almost caused a wreck as I had to quickly think and get to the side of the freeway. It happened 2 more times that day til I got it home and got the engine code P2111. I found out later its a faulty throttle body that they used in Fusion and other models and everyone is having this same issue of it randomly cutting off. It's a faulty throttle body that should be recalled!

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.

Throttle body failed and had to be replaced three times. Put me in danger for my life as the car stopped running on busy highway. Vehicle was in motion full speed 55 mph and throttled down to complete stop. Engine raced but would not move. I want reimbursement for my expenses. Throttle body was replaced three times for failing within a week. Warrenty extensions have been issued for throttle body fails for similar models. We have been informed that Ford has issued an extended warranty for defective throttle body assemblies and sensors for 10 years or 150,000 miles from the data of original purchase. For vehicles past this time limit, the warranty is reported to be valud until January 31, 2015. Affected owners should contact Ford and mention consumer satisfaction program 13N03.

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.

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 NHTSA 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"
