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.

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.

I can be driving my car and it will just lose power... I can be sitting at a red light...I can be on the highway and it'll just stop pulling... The check engine light pop on and a wrench light pops on the dash....I have to pull over out of traffic which is extremely dangerous onto the side of the road...I would turn the car off and wait a minute.. Start it back up...the wrench signal is gone but the check engine light is still on...this has been going on with this car for a while now...and I took it to auto zone... They did diagnostics on it and said it was the eit or throttle body.

Intermittent loss of power steering while driving. Have to constantly try to turn off car and restart to get the electronic power steering to work again. Lost power steering on the interstate with kids in the car and ended up in the grass, almost taking out the guardrail. Ford dealership says there have been 450,000 2011-2012 vehicles that have been recalled for this exact problem and part, yet somehow the mustangs weren't in the recall. Dealership quoted $1500 to replace the same part that is being recalled on other vehicles. I have read many other people are having this problem with the same mustangs. I'm afraid to drive my kids and family anywhere in this car! It's an accident waiting to happen!!

Immediate loss of power and complete loss of acceleration. This has occurred in an intersection and in the middle of a multi-lane highway at 35 MPH and 60 MPH and when either accelerating or holding at a steady speed. The wrench light comes on and the vehicle immediately loses power and decelerates regardless of speed. The vehicle is inoperable until it is turned off and restarted. The problem is recurring and unpredictable. Because the code disappears upon restarting it cannot be diagnosed. I had to get a code reader to get the code which had to be used after an emergency stop along the highway. This is dangerous as there is no warning before the loss of power. Error code p2111-throttle actuator control system stuck open. The problem has occurred 10/29/15, 11/16/15, 11/25/15, and 11/30/15.

When the car was about 3 years old, I started to feel a quick loss of power in the steering when making a turn. It had only lasted a second and only happened at low speed in parking lots but happen while I was driving so I took it to the ford dealer in fullerton ca. They said it was a software problem and they updated the software. The problem disappeared but then reappeared about a year later. I continued to drive it cause it was only occasionally at low speed for a half second in parking lots. Then in the morning of october 16, 2015, the steering of the car locked while I was in the middle of the street for about 5 seconds. Two yellow warning lights then came on in the dash and the steering released. One warning light said "service advance trac." I slowly drove it to the ford dealer in fullerton on residential streets since it was nearby. I no longer felt safe to drive the car. I told them the problem. They kept the car until october 20. The mechanic told me he had to change the entire power steering system because of an internal failure and the charge to me was $1733. I complained but had no choice since I needed the car repaired. I have seen very similar complaints on the internet about other mustangs. Ford recalled several other models earlier this year for the same problem; 'a potential intermittent electrical connection in the steering gear' that ford says 'might result in the loss of electric power-steering assist while driving.' these models included 2011'2012 ford fusion, 2011'2013 ford taurus, 2011'2013 ford flex, and 2011'2013 lincoln. I believe ford knew of the problem but decided to pass the cost of repair to affected customers rather than do the recall of that model. This risked the life of myself and others because it resulted in a loss of control while driving. I believe I am entitled to the cost of this repair from ford. Thank you.

Driving down an interstate a wrench came on the dashboard and car went into limp mode. Pulled off turned the car off and restarted it. Got to the destination ok but on the way back home the wrench came on again. Looked at the code and saw it was the p2111 code. It happened 4 times in the way, losing power and shaking. Taking it to ford tomorrow to find out if it covered under the warranty. There was no recall in the car,however, I am noticing a lot of people are having this issue. This is a safety issue and should have a recall on it. From what everyone else is saying ford is not doing anything to help or fix the problem.
