While driving my 2011 ford mustang (with a v6 engine and automatic transmission) at 40mph on a local street, I experienced the vehicle unexpectedly losing power and a fault light in the form of a wrench appearing on the dashboard. The engine speed dropped down to idle and did not respond to any gas pedal operation. The cars engine remained running, however, the engine ran roughly as evidence of it shaking the entire car. The incident placed myself and other drivers around me in danger, as I had to move quickly to get my vehicle out of the moving traffic and into a safe place off the side of the road.

Vehicle stuck accelerator at slow and higher speeds!! It happened once while I was driving it and once while my daughter was driving. This could easily cause severe accident. Throttle body was replaced by dealer. This accelerator problem happened after the throttle body was replaced. By the dealer. I brought it back to the dealer after this incident and they called me and said "they can find nothing wrong". I told them to keep the car until the find the problem as this out of control acceleration is very dangerous.

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.
