The vehicle will at times appear to lose power and go into "limp home mode". a non-dealer diagnostic revealed a "P2111" error code for "throttle actuator control system - stuck open". this symptom has occurred multiple times at multiple rates of speed, resulting in dangerous conditions. The dealer has so far refused to replace what appears to be a defective part.

Two days ago my car stalled without warning, I lost all acceleration, and then the check engine light came on. I was able to safely pull to the side. I turned off the car and was able to start up after a few minutes. Today while on the interstate, in the middle lane, during rush hour traffic, my engine suddenly stalled again and the check engine light came on. Luckily again, I was able to put on my hazard lights and coast to the side of the highway. I am grateful traffic was moving slowly and it did not happen when I was traveling at a faster speed. The engine started back up after a few minutes. I will be taking it to the dealership in the morning.

Driving down the freeway at about 65 miles per hour when the car dies and starts a violent shake. Luckily there wasn't much traffic and I could pull off to the side of the road with my three kids, if it would have been busy there would have been an accident. I have read alot of complaints about this problem with the 2010 Ford Fusion is it going to take a couple deaths for them to recall this car for the problem. It has happen to me three times now once when I was going about 35. I think Ford needs to recall these vehicles and fix them before somebody gets killed if they haven't already.

Driving and car sputtered and lost power. Wrench light came on. Pulled off onto shoulder. Turned car off. Restarted car and tried to drive again and same thing happened. Had car towed to the dealer and found that throttle motor was not responding. Dealer replaced throttle body and motor. Could have been very dangerous if happened on the highway at higher speeds.

Driving interstate hwy at 65 mph, vehicle lost power. Traveling in the middle lane, the vehicle slowed in rush hour traffic to 5mph. I said my prayers due to the heavy traffic, thought this was the end. Was able to coast to the shoulder and called for a tow truck. Dealer reported that the throttle body had failed. Failed part replaced and vehicle is working normally.

Our 2010 Ford Fusion lost engine power while accelerating up a hill in morning rush hour traffic on a multi-lane super-highway in atlanta. Our car was in one of the left lanes and was able to limp across several lanes to the right shoulder with the assistance of a helpful truck driver. Cars were racing around us on both sides until we could flag down assistance. The experience was horrifying. The car was towed to the Ford dealer who diagnosed the problem as a stuck throttle cover. A repair was made under warranty, and we were told the car was safe to drive.

In moderate traffic on I385, traveling at 60 mph, without any warning signs there was a sudden "clunk" and the engine lost power. Weather was clear and sunny with an outside air temperature of 64 deg. F. pavement was dry. With my wife and two grandchildren in the car I had to cross two lanes of moderate traffic to safely get to the breakdown lane. Some cars around me had to make avoidance maneuvers. Not good! once I got stopped in the breakdown lane with the emergency flashers activated, I determined that the engine was still running with the RPM surging between approximately 700 and 1500 RPM. I was able to drive in the breakdown lane to an exit ramp at approximately 5 mph with the car jerking forward with the change in RPM. The "wrench" light was on but no "check engine" light. Once on the exit ramp I turned the engine off and attempted to re-start it. After a long cranking cycle the engine re-started and ran normally. There was no "wrench" or "check engine" light after the re-start. The car ran normally on the trip home (approx. 10 miles). The engine is a 3.0 liter, V-6 with "flex fuel" capability.

Traveling approximately 45 mph during rush hour traffic the 'wrench' light illuminated, the vehicle lost power and the engine began idling very rough. Fortunately I was able to get out of traffic and pull off to the side of the road. The engine was idling very rough ~900-1200 RPM and was unresponsive when I pushed the gas pedal (almost to the floor). Once stopped I turned the engine off, waited approximately thirty seconds and restarted the engine. The warning light was extinguished and the engine operated normally. I accelerated back to traffic speed and within five minutes experienced the exact same thing. I pulled over, turned off and back on the vehicle and again the light extinguished and the car ran normally. Two more times within a thirty minute period the vehicle experienced the same thing. En route to the Ford dealer the next day I had the same thing occur three additional times during the ten mile drive to the dealer. Each incident was identical. The dealer found no codes (since the light had cleared when I turned the car off and on) and hooked up an incident recorder. I experienced the same shut down three additional times and captured them on the recorder - upon return to the dealer the next day they still did not have any codes to investigate (?) the dealer 'thought' they knew what the problem was (even though they "hadn't seen anything like this before") and replaced the throttle body. Since replacement I have not had any additional mishaps. I'm glad I did not cause an accident due to the sudden loss of power but, as I explained to the dealer, I felt that the vehicle was unsafe to drive. I hope they fix this issue asap - there needs to be a recall and soon!

Driver was going 35-40 mph and suddenly experienced a severe loss of power as if the car transmission was put in neutral.was a scary experience!! had to put on emergency flashers to keep from getting hit from behind.car was driving very slow and then after a period of time, full power came back on.

Read in paper that you were looking at Ford throttle body. I was in fast lane on I-66 on a Friday afternoon. Suddenly car stopped. I was lucky there was room on left apron to pull off. Car restarted when I tried--went 1000 feet and stopped again; now in right lane and pulled off. Knew there was an off ramp 1/4 mile ahead and limped on apron with cars passing. The entire situation was very dangerous in my estimation. When restarting, it was hard to tell if auto was running or not. When restarting auto backfired etc. Prior to this incident had reported to Ford dealer that transmission sometime "clunked" when I put auto in reverse in the morning. They found no problem. Have not had this problem since I paid to have the throttle body replaced.

My wife was turning left into a parking space in a parking lot at 2mph or less when the vehicle suddenly accelerated at high rpms. Our vehicle slammed into the vehicle to the right of the space my wife would have entered. Heavy damage was caused to our veh. And to the parked veh. My wife was unsure if she had caused the acdt or if it was a mechanical defect. Because of the very heavy and rapid acceleration, I didn't think it in any way was driver error. After it was repaired, our 2010 Fusion was checked out by a Ford dealer and nothing was found amiss. A year later in Nov. Of 2012, I was driving the car at approximately 50mph when the engine suddenly revved up about 150 to 200rpms. This didn't cause any great acceleration but, considering my wife's experience, I immediately shifted to neutral. Just as I got into neutral, the engine revved up to 2500 to 3000rpms. Had the car been in drive, a collision could have happened or I could have lost control. Ford was contacted, car inspected, again nothing wrong. A service writer tried to tell us that the rubber floor mat was on the accelerator pedal. The mat doesn't gain weight to suddenly depress the pedal all by itself! Ford's great lakes regional manager was not very forthcoming-she wasn't apparently aware that there were youtube videos of 2010 Fusion owners filming their dashboards as their cars did the same as I have described above. The car is being driven regularly but both of us have a hand on the gear shift alot of the time. Considering our experiences and the youtube postings, I think Ford is trying to avoid an expensive recall. Didn't Toyota use the floor mat excuse for years?

While going 70 mph on the highway I experienced the same issues. My car stalled out shut off the cruise control and started shaking uncontrollable. I shut off the car and waited about five minutes and started it back up drove maybe another ten miles and it started again. On the following day I took it to the dealership where I purchased it from and they made it seem as if I had no ideal of what I was talking about. Once they realized I knew that it was the throttle body assembly that was the problem I was told that this was not a part that was covered under warranty so I would have to pay for it out of pocket. I took the time to talk to several reps at Ford and I was told that if the mechanic did not think it was defective then there was nothing they could do. I talked to the mechanic at the dealership and they told me that it just stopped working. So I ended up paying $479.05 for a new throttle body assembly and having to be without my car for a total of four day. Only to get it back with a cracked windshield, but that is a different issue.

On Feb 13 2013 I was driving and the car nosed over, slowed to approx 8mph, with engine surges of up to 1500 RPM, after several restarts it ran normally. On Feb 17 2013 it did the same exact thing, I stopped and restarted the engine several times in the 40 minute drive of 3 miles back home but that did not help. After the car set for several hours it started and ran correctly. Research on the internet showed hundreds of the same problem and replacing the throttle body corrected the trouble. On Feb 18, 2013 I took it to the Ford dealer and from only my description was told that the throttle body was the problem, they had 3 in stock and my three year warranty has expired on Feb 21, 2013, less than a month out of warranty and it would not be covered so I drove the car back home, I called a different Ford dealer who sold me the throttle body at a discount. It took me about ten minutes to install the throttle body, and the car is still running as it should.

My Ford 2010 Fusion, when at a traffic light, stop sign, etc.. would stall when I put my foot on the accelerator with very little response. Then it will finally pick up speed. I have not experience the "engine shut down" as of yet and I hope I don't. after reading the other "complaints", now I know what the problem is. Will take care of it as soon as possible!

- Riverdale, GA, USA

While driving on the freeway at 65 mph. The engine lost power as the engine light and wrench light went on. Pressing on the accelerator had no responsive. I had to navigate freeway traffic with no engine power to get off to the side of the road. As I came to a stop the car jerked a bit before I put it in park. I turned it off and let it sit for a while. After turning the car back on I got back on the road, only to have it happen again a few miles later.

- Goodyear, AZ, USA

Driving the car suddenly slowed into a limp mode. This happened several times. The final time was on a major highway at 55mph. Luckily I was able to maneuver the to the side of the road before getting rear ended by traffic from behind. This is dangerous condition! after visits to 2 Ford dealers, they replaced the throttle body. The car was out of warranty by mileage, (not time), so we ended up paying out almost $500 for the repair and car rental.

As I was leaving work and pulling out of the parking lot, the engine sputtered, choked, wheezed and eventually would not go over 10-15 mph. Check engine light came on and vehicle died. Had the vehicle towed the next day to the local Ford dealership and was informed that I had a defective throttle body that had caused the problem and also had created a lot of debris in the fuel intake system. Cleaning of the fuel intake system and replacement of the throttle body was around $700. I didn't think anything of it at the time until I saw on the news that NHTSA had opened an inquiry into this possible defect on the Fusion, so I wanted to add that I had a similar problem as was being investigated.

- Annapolis, MD, USA

Driving on an interstate about 55 mph and wrench light came on engine lost ability to accelerate I.e. went into safe mode and had to maneuver through traffic to the shoulder. This occurred multiple times from July through August 2012 on various types of roadways (highway, neighborhood roads) until the problem was fixed by a Ford dealership. Cause of the problem according to the invoice was the throttle body. They replaced the throttle body and the problem has gone away.
