Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: Ford significantly updated the Fusion for the 2010 model year. We wish they hadn't

Throttle body issues have led to a ton of reports about a sudden deceleration and loss of power while driving. Ford issued a “customer satisfaction program” in March 2014 that, unsurprisingly, has left very few customers satisfied.

2010 is also the year we started seeing complaints about the power steering failing. Throttle and steering failure? Yeah, that’s why this is a clunker.

Fusion 4-cyl

  • 29,710 miles
Driving at 45 mph, car loses power and/or acceleration. Wrench light illuminates and pulled car to side of road and vehicle shakes terribly. Shut car off and waited a couple of minutes and restarted car. Wrench light was not on and car ran fine. This problem has occurred on three more occasion within a week. Dealer could not find any codes but stated it would be a problem with the throttle body, even driving the car by a mechanic with a diagnostic tester, they could not duplicate the problem. This is a serious safety issue that Ford evidently does not want to fix under warranty because their is no code yet. Their are a lot of complaints on this issue on the internet. Ford needs to recall this part.

2 days in a row, driving 40-50 mph and my car completely loses acceleration. The wrench light goes on. I have to roll to a stop on the side of the road while the car shakes like it is stalling out. I turn the car off and wait a minute or two then turn the car on and everything is back to normal, no wrench light, no problems... until it happens again. This is very dangerous as I have a 10 month old daughter to drive around and wouldn't want to put ourselves in a dangerous situation on a busy road or highway. After researching online this problem seems to be a recurring issue with many Fusion owners around the country. Please help.

Fusion 6-cyl

  • 37,300 miles
While leaving a stop sign and pulling onto a main road, vehicle jerked and lost all forward motion. No response from the accelerator and engine ran rough below 1000rpms. Wrench light on dash lite up and car won't move hardly at all. Was barely able to get out of the traffic area of the street. Put the car in park, turned off the engine and restarted the car. Ran fine for 1/2 a block and went into limp mode again. Was able to make it onto a side street this time. Repeated the noted process above and was able to drive the car home. Parked the car in my garage and was afraid to drive it afterward. Contacted my mechanic and dropped off the car the next day. He stated it could be the throttle body or related problem based on my description. No codes present on the computer after the wrench light went off on restart.

Was driving on the highway at about 65 mph and the car lost all response to the accelerator, pressing on the gas did not accelerate the car. Pulled over to the side and car ran a rough. Turned the car off, waited about a minute and restarted. Car restarted fine and drove fine after that for the rest of the trip. My wife drove the car the next day and had the same thing happen while she was on the highway. She saw the check engine light come on (I don't recall it coming on, but may have just missed it).

Driving on the highway going approximately 70 mph when my car acceleration seize to accelerated. The wrench light and check engine light came on. I coasted to the shoulder of the highway were I put my hazards on. I shut the car off waited 5 minutes then started back up. I turned around drove home. This happen two times before on the same day. I read a forum of other Fusion owners who this happen to. They all said it was the full throttle body. I replaced the part and not had a problem since.

Fusion 6-cyl

  • 85,000 miles
Vehicle suddenly stalled while at 25-30 mph, making it difficult to safely move to the side of the road. This occurred on a city street, but had it occurred on a multi-lane freeway at highway speeds, this could have caused a serious accident. Vehicle eventually came to a speed of 2-3 mph. After restarting the vehicle, it was able to reach 10 mph while driving for service. Later that same day, the technician was unable to re-create the scenario. The next day, the vehicle started to encounter rough acceleration from idle, was brought back to the same mechanic, who encountered the rough acceleration, and diagnosed an electronic throttle body failure. Part was replaced, but mechanic noted it was on "critical nationwide back-order" because of wide-spread failures of this same part on Fusion and other Ford models. Situation appears to be resolved.

I had just started and was exiting a retail establishment. I was driving down a slight incline approaching a stop light when the car started shaking and dramatically lost speed. The wrench light came on which according to the manual indicates a possible powertrain/transmission issue. I turned the car off and then restarted (in the middle of the road) and drove to a safe location. I was lucky that at the time I was driving at a slow speed and approaching a stop light. If a car had been behind me someone would have been injured.

Car lost power while driving on highway, vehicle slowly coasted to a stop despite pressing the accelerator, only worked after turning vehicle off and restarting with the key. This has happened twice while traveling on the highway and once at about 45mph. Throttle body needed to be replaced.

I was driving and the car power shut off and then the wrench light came on and then I had to restart the car, it took a while but it came on and ran good for a few months and it happened 4 times after that. Every time the dealer said they could not find an issue. This last time it happened the engine light stayed on and I had to get the car towed and was told it was my throttle body issue that is a known problem but no recall.

Driving 40-60mph, car suddenly loses throttle control, wrench light comes on. After it happened I took it for service and was told there were no error codes. It has happened 6 more times, and I was almost in an accident on the highway today. Car continues to idle after losing speed, but runs rough. Turning the car off, and back on- and it runs normally again. After web search it seems this is a known issue with defective throttles and NHTSA is investigating.

  • 43,000 miles
I was driving home at a speed of 70 from work on the freeway when the car powered down all of a sudden. A wrench light turned on and the accelerator pedal did not work I had to pull to the side of the freeway when I stopped my car the car felt as if it was trembling so I turned it off for a few seconds then turned it back on surprisingly the wrench light turned off and the car worked fine again. I kept driving carefully at a speed of 60 now and 20 miles later it stalled again. My car at the moment is at 43,000 miles I bought it new in June 2010. I took it to O'reillys so they can troubleshoot and find out what was wrong with my car and they said it was the throttle body. I continued to call a Ford dealership since I still have powertrain warranty which covers the engine and transmission but unfortunately the sales rep. Said it did not cover the throttle body. At the dealership to fix this problem will cost me $93 to find the problem, $150 for the service and $400 for the part. I am a nmsu student living in Texas and drive 30 miles everyday to school and sadly cannot afford this kind of expense. I'm afraid to keep driving it causing to get rear ended while the car stalls or even worst causing a car incident leaving injuries.

We were driving along a city street heading toward a busy freeway. We stopped at a red light. When the light changed my wife accelerated (pushed the pedal) to get going the car traveled about 500 feet. It lunged and slowed to about 2 - 3 mph. When my wife tried to accelerate again the car wouldn't speed up. We pulled the car over to the curb as best we could. The car wouldn't start right away. A yellow warning wrench lit up showing this to be a powertrain problem. The car did start after about a 5 minute wait. We drove it home and parked it. I am afraid to get in it until it is checked out by the dealer. Thus, I am having it towed to the dealer this morning. I have read online of a similar incident happening to other owners of the 2010 Ford Fusion. Had we reached the freeway and had it stalled like this we could've caused a serious accident involving other vehicles.

Fusion 6-cyl

  • 63,120 miles
While driving on the freeway my car was running but when I pushed on the gas nothing was happening and the yellow wrench light was on in the car. I had to coast out of the way of all the traffic with being ran into and thank goodness it wasn't during rush hour. This has happened five times since I bought the car used and it doesn't even have 65,000 miles on it yet. I have already taken it to the shop and they determined it was a clogged fuel injector. That was cleaned it the car ran fine for half a day and then it did the same thing twice in one day within fifteen minutes of each event. I put the car in park and turn it off and turn it back on and its fine. This seems to be a problem with the throttle body which seems to be the issue that is all over the internet. This needs to be recalled because its a matter of time before someone dies or gets hurt when this happens to their car.

  • 49,000 miles
I was driving 35-40 mph when all of a sudden my vehicle slowed, started shaking, the wrench light came on and my gas pedal would not respond. I pulled over, turned my car off, waited for a moment then turned it back on. The check engine light was on but it seemed fine so I decided to continue my drive toward home. 10 minutes later, as I was getting off the highway at 55 mph in rush hour traffic, the car suddenly started shaking, slowed to limp mode and my gas pedal became unresponsive. I continued in limp mode trying to get off the highway and pulled into a business parking lot. This happened several more times as we drove in the parking lot trying to diagnose the problem - once even coming to a complete stop. We used a code scanner, but no codes were being set. We suspect the throttle body but local dealer has none and we R told it is "deep back ordered". not only do I now have no car to drive, but it is extremely dangerous!

I was driving on the highway going 70mph taking my son to hospital and was almost killed. My car did not cut off just stalled. I come to find out it's a faulty throttle body. I cut car off restart and a mile later it happens again. I was so close to being hit. This problem is very serious.
