Driving the car home from the dealership cruising down the highway and suddenly the car just would not accelerate any more. Scary feeling when your cruising at 55 and suddenly the car would not stay at highway speed. It would still idle but it idled roughly. You could push down on the pedal but it would do nothing. It just lost all power so I had to quickly pull onto the shoulder of the road. Good thing no one was following me to close. I called the dealer and they sent out a tow truck. I had to get a ride home and the car went back to the dealer for repairs. Turns out that the throttle body sensor quit working.

I was driving about 30 mph on a two lane, rural road when suddenly my 2010 Ford Fusion started sputtering, coughing, jerking. The car slowed down to a crawl and would not respond to my pressing the accelerator; then the engine shut off and a red-wrench light appeared on the dash. I cranked the car again; in park, the engine sounded fine, but when I placed it in drive, the sputtering and coughing started again. I drove a few feet, again without any response from the accelerator, and the car shut off again. I repeated this three times, all to the same effect: Drive a few feet, engine is coughing, sputtering, jerking, then engine shuts off. After the third time, I cranked it, but while still in park I revved up the engine as high as I could (accelerator to the floor). After that, when I put the car in drive, there was no coughing, no sputtering, no jerking, accelerator responded smoothly. I was able to drive home (half mile) and park the car. But I am terrified the problem will happen again--this time in heavy traffic or even on the interstate--and the engine may again stop without warning while I am driving along. I am even too afraid to drive it to the repair shop. A scary dangerous car.

I was driving at approximately 60mph on a highway and the engine suddenly revs but all the power is gone. The engine couldn't maintain a gear and started decelerating in the middle of traffic while the little service wrench light came on. I had to quickly get off the road and to safety before I was run off it.

While driving at speeds over 30 mph the engine will loose power and the rpms will drop and then rev back up. This happens when there is a quick acceleration, like merging onto the freeway, pulling onto a busy street. The worst experience happened just last night, March 2,2015. I was accelerating from a stop on to a busy street and the car stuttered and shook as if it was a manual transmission. I had no control over the speed of the car and traffic was coming towards me in both directions. Out of nowhere the vehicle clicked into gear and accelerated. We replaced the throttle body last year and are still having the same problems. Replacing the throttle body has made no difference. This vehicle is completely unsafe to drive in its current condition.

The first time I noticed something wrong I was trying to pass a slower moving car. I turned the signal on, moved over to the passing lane, went to accl. And the car basically red lined and went no where. So I don't pass and god for bid pull out in front of faster moving cars. Now, after driving across town, and it gets up to normal running temps the car has trouble shifting around 3rd through 5th gears. It lurches like it would if a new driver in a manual transmission might do, until you let off the gas and I guess let the motor catch up.

Wrench light comes on. Ford is trying to say it's covered because the wrench light is on, and then bring you in to the shop to pay $2000 for a valve body in the transmission. They are pulling the wool over the NHTSA by making it seem like they have covered it when it's something entirely different. Should have bought a Nissan. Basically the car doesn't accelerate. Come the time I might get hit by a car, I wont be able to accelerate properly.

I filed an original complaint regarding sudden failure of my vehicle to move or produce any power back on 10-05-2013 under NHTSA id number 10546865. At that time I described the following: Summary: I was at a stop light. The light turned green and I began to accelerate to about 10 mph when the car suddenly began running rough and I could not increase speed. It slowed down to about 3 mph and the wrench light came on and no matter how far I pushed the pedal it would not move past 700 RPM. This repeated itself several times more that day. Did it again and it seemed it was increasing in frequency. Took the car to the dealership and they said the throttle body failed and that it is a common occurrence. It had an error code of P2111. Filed original complaint because I was informed that there was a large number of these failing prematurely and to document my vehicle. I paid the repair in October 2013 for exactly same symptoms P2111 and same conditions as all of the other vehicles in this investigation were experiencing. I kept track of NHTSA's investigation came to find out that Ford had issued a "customer service campaign" earlier this year that extended the warranty on the throttle body to 10 years/150K miles and a letter would be sent out. I never received one. Contacted my dealership who said they did not see anything under my VIN but would send the request to Ford. Ford says that NHTSA determines which vehicles fall under the issue. So just contacted NHTSA via telephone speaking to [xxx] who said that since I already filed a complaint with NHTSA that she could not help me but said for me to go online and update my complaint so that the NHTSA engineers would investigate further. In warranty database I found many 2010 Ford Fusion produced before and after mine (**/**) with the same problem. I would like a call from a NHTSA engineer please. Thank you.

Car was at a complete stop. Engine began to race (sudden unintended acceleration). Car began to lurch forward. Applying brake full pressure would not stop - had to place in park. Incident continued for 30 seconds. Had happened over 20 times since July of 2014. Took car to local dealer and ran diagnostic on ecs. No codes reported. Filed case with Ford Motor Company. They will not address problem because no fault codes are being reported. Have case number but did not include as could be security risk. Incident has not occurred since.

Since this vehicle was made with no gas cap my engine light is always on. Any little bit of dirt I drive yet gets into the seal of the gas tank so my engine light pops on and states there is some sort of leak in the system. I can't afford to keep taking it in to pay and arm and a leg for the dealership just to blow out the seal. So my engine light is always on. This is a very dangerous problem because you never know if there is an actual problem with the vehicle or if it's just that dirt in the seal of the gas tank. Big mistake by Ford and they should fix it or they will definitely lose my business...which I've been Ford loyal since I was old enough to drive. I will also deter anyone else I know from buying for just for the capless gas tank feature!!!!!

Twice the vehicle ran properly and was parked. Upon starting the vehicle, it ran fine for some seconds. As I pulled into traffic, the vehicle inexplicably lost nearly all power. The engine ran extremely rough and the car would barely move at all. I could barely get off the road because of the extreme loss of power and very rough idling. The wrench indicator light came on both times, but the service engine light did not come on either time. After shutting off the car and restarting it, the car operated normally.

Wife called me at 6.15 am on her way to work and advised the car stalled in the middle of the road wrench light, service light illuminated. She was able to restart car and continue driving. The next 3 minutes the car stalled again with just the wrench light illuminated. I told her not to drive the car and to see if it would start to get to a safe place. She was able to move the vehicle to a safe place. I will now bring this vehicle to a dealer. The transmission is also jerking, clunking and not shifting properly. There is certainly a transmission and engine problem with this vehicle. Please continue to investigate, recall or have Ford fix the issue at no charge to the consumer. Thanks you

While driving on the interstate, the vehicle completely lost power under acceleration. I took it to a Ford dealer and they fixed it free of charge. They said that they are aware of the issue, but have not had time to send out a recall yet.
