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.

This is my second complaint in as many days - about the exact same problem. This incident happened two days after the first one. Traveling on a city street approximately 15-20 mph and the car suddenly loses all acceleration and the wrench light appears. I was able to putter to the side of the road and shut the car off. When I restarted it, it ran fine. It goes to the dealer today for inspection, where I suspect I'll get the same response that most every one else gets - that the problem couldn't be re-produced. What will it take to get a recall from Ford about the defect in their design" fatal accidents?" that's a pretty high price to pay before they're forced to correct their product.

Traveling on the street at about 40 mph, car shuddered to a stop. Engine light came on. Had car towed home. Car started the next day. Carefully drove the car to the Ford dealer. They replaced the throttle body. The throttle body should not be failing at 60000 miles. This should be a recall.

I own a 2010 Ford Fusion with 19000 miles. I haven't even had it a month yet. It is a certified pre-owned vehicle. Driving home from work yesterday, I stopped in a line of traffic at a red light. The light turned green and I accelerated. During acceleration, the car jerked then lost all forward momentum and "puttered". I was able to "putter" to the side of the road out of traffic. I put it in park and noticed that the wrench light was lit up, so I pulled out the owner's manual to see what it meant...powertrain. I turned the car off for about 5 minutes then restarted it with no other incidents on my way home. Thank god I wasn't in any heavier traffic or multiple lanes! from what I've been reading, some people have lost acceleration going 50+ mph in interstate/highway traffic! if this problem isn't addressed, and soon, someone will be seriously injured or worse due to a defect in Ford's design.

At 11:45 pm, I was traveling West on I-64, at 68 mph, when my car quickly decelerated. Despite my applying more gas, my car continued to lose power rapidly and began shuddering. It was then that the "wrench" warning light came on. I immediately pulled over to the side of the road, turned my vehicle off and put my hazard lights on. I waited for a 5 minutes before starting the car again. The car started roughly but did not have any power and could/would not accelerate. It was at this time that both the wrench and engine warning lights came on. Again I turned off the car and waited. After another 10-15 minutes, I turned the car on again. This time it started without incident. The wrench warning light did not come back on but the engine light remained on. I kept my hazard lights on and remained in the breakdown lane while I drove approximately 5 miles to the closest exit off the interstate where I promptly parked my car.

Wrench light comes on, car kicks out of gear into idle mode, will not accelerate, shakes violently. I was able to coast to side of road and turn off engine. Restarted engine with longer than normal cranking time. Gear changes (automatic) continues to be sluggish and happens at highway and city speeds.

Throttle body malfunctions while car is at speed. The "wrench" light appears on the display and then the car loses power and begins to shudder. Turning the car off and restarting it resets the display and starts fine. Problem is intermittent but dangerous as the car stops working while the car is going anywhere from 25 to 45 mph.

I pulled out of my works parking lot and got 50 ft. Car began to slow down, shake/ vibrate violently, and emergency wrench lite lit up. While driving and while in park, it shook. I went to pull off to the side of the rode safely. Thank good ness I was on a downhill and could coast to a side road (but still not safe where I was). Once I was pulled off major road, I put the car in park. I turned the car off and was too afraid to do anything else. I called for a tow. 24 hours later, I was told my car's computer code said it had a bad throttle body. It was replaced with a brand new, revised throttle body - under warranty which ends in 37 days. It happens to many Ford Fusion. It's time for Ford to own up and send out the recall notices before someone gets hurt/killed.

  • 76,800 miles
I was traveling down the highway when my car stopped getting power when I pressed the gas. A yellow wrench warning dash light came on, the car started shaking and had no power when trying to accelerate to get over a lane to get off the road to avoid an accident. I luckily got over with my hazard lights on and coasted to the shoulder where the car finally stopped but did not shut off or die. The car idled and continued to shake so I popped the hood and checked the transmission fluid level. The level was slightly low which was strange cause I had to add half a qt of trans fluid the month before because the shifting was rough. The fluid was very dark colored and smelled scorched. I shut the vehicle off and let it sit for about 10 minutes then I checked the oil, ok. I turned the car back on, added a little more trans fluid and the car seemed to be ok to get me the rest of the way to work. I left it in a parking lot for the night and returned to check it out in the light. I jacked it up and found some fluid slowly coming out of the place where the axle goes into the transmission. I called the Ford service center, explained what happened and explained what I found. I had the recall for the transmission done in 2011 for Ford Fusion 2010S but the rough shifting has been a problem since I bought it. I have had constant trouble with the transmission shifting rough and now losing all power while driving on the highway at 55mph. It almost caused an accident. My car is now at 76,800 miles and Ford service rep says the bill is on me cause the powertrain warranty is up and the recall for the same problem doesn't cover me anymore. I want my car fixed with this problem and I cant afford to keep going to the shop every time this keeps acting up. Ford needs to fix the problem with their transmissions before someone gets hurt by this. Luckily my 1yr old daughter was not with me this time.

I recently bought a 2010 Ford Fusion with $45000 miles on it. After having owned it for only about 2.5 months I am having problems. While driving down a 4 lane highway at 55 miles per hour it almost stops in the middle of the highway and will not accelerate. It does this with no warning. I am able to pull over to the shoulder and the car begins to shake as I come to a complete stop. Once I turn the car off the wrench light goes out I am able to start it back up. It has happened several more times. Today it happened in the middle of a busy intersection. The Ford dealership in my area when I called said it would be hard to diagnose because the problem is intermittent. By reading the complaints from everyone on the 2010 Ford Fusion this a common problem with this model. The issue seems to be the throttle body. My fear is that someone will slam into my car not realizing it has stopped in the road. I really think it is a safety issue and cannot believe with being such a wide spread problem Ford has not done something to correct it before someone is injured from what appears to be a defective part they have put on their cars.

I was slowing to a stop when my car shuddered and the engine seemed to die. I had a error symbol for the transmission and the engine had no more power. It was stuck in idle now even though I was just doing 35 miles per hour coming to a stop. As I finally braked to a stop the engine was surging, but when I pressed the gas pedal, nothing happened to the engine, it was as if it was just turned on and placed in drive only. I didn't know what to do, I had to get through 2 intersections on idle speed only. I finally pulled over past the intersections and turned my car completely off. I then turned it back on and it was working normally. I took it to the Ford dealership, who told me this is common after a new battery is placed in these Fusion. They noticed my recently purchased used car (purchased about a month before this) had a brand new battery in it. They told me with a new battery, the carbon builds up dramatically and damages the throttle body. So I need to buy a new throttle body and have the cars acceleration computer reprogrammed. And this might happen every time I get a new battery" please investigate this occurrence with other Ford dealerships. I have reading this same story all over the web. Why doesn't Ford do something to correct this issue"

Fusion 6-cyl

  • 45,467 miles
I have a 2010 Fusion. I purchased the car as a certified pre-owned. The car stalled 6 times on the way home last night. The wrench light would go on and there was no throttle response. The car would shake and sputter. I would shut the car off and restart and could proceed for a short distance. The last time it stall on the freeway on ramp. I took it in and let the dealer know what had occurred and they called back indicating it is the throttle body. I am out of manufacturers warranty. The cost is $500. The power train system is covered but the throttle body is not (even though the throttle body causes the power train to go into stall)" at what point will they make the choice that the throttle body that is in these cars are not up to par and a safety hazard and make it a recalled item"

On way home from work, driving for 30 miles, going 50 mph, upon changing lanes, the acceleration died. Wrench light came on. I was able to pull over on the highway. Thankfully, just got through the eight miles of construction with no shoulder and only one lane. If it happened then, I could have caused an accident or at least angered quite a few people on their way home from work by stopping traffic with no way to get around me. As the car was idling, the tach was jumping all over the place, so I put it in park and shut the car off. Waited a few minutes, started the car and was able to drive the additional mile home. Called the dealership to have this checked out. Cannot get in for several days. Holding my breath driving it back and forth to work on major highways until then. My first major disappointment with Ford for not recalling this issue.

The car basically stalled without turning off. The "wrench" light turned on and the car lost all power and the accelerator was unresponsive. The car would only go 2 mph. Once stopped and placed in park, the car idled very rough. Then turned off the car. When re-starting the car it started poorly, but once started the wrench light was off. The car then drove normally. This happened 3X that day. I am lucky I did not get into an accident when I lost all power and had to pull over. Ford will not fix it citing they cannot see the code. I am afraid to drive this car for fear of an accident.

The contact owns a 2010 Ford Fusion. The contact stated that the accelerator pedal became inoperable. The vehicle was taken to the dealer for inspection where they stated that the torque converter needed to be replaced. The vehicle was repaired but the failure recurred. The contact took the vehicle back to the dealer where they advised that the power assist warning light was illuminated and that the power steering needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and advised the contact that the vehicle was no longer under warranty. The failure mileage was 53,000.

Fusion 4-cyl

  • 32,200 miles
We were traveling on busy I-80 at approximately 70 M.P.H. due to busy vehicular traffic on the interstate hi-way, I was not using the cruise-control. When we experienced the incident, I had pressed on the gas pedal to maintain speed on an uphill section. On the uphill section, I noticed the vehicle did not accelerate and the instrument panel warning lights started flashing. Even with heavy traffic, I was able to negotiate maneuvering the vehicle to the shoulder. As I was coasting on the shoulder, I shifted the transmission to neutral and tried to start the engine (ev system did not respond either) with no avail. After coming to a complete stop, I shifted the transmission to park, turned-off the climate control system and the and radio. I removed the ignition key and re-installed it and proceeded to start the vehicle, the propulsion system (ev mode) responded. We accelerated on the shoulder in ev mode and we reached speed the gas engine responded and we were back on I-80 and traveling with the traffic flow. This is first time this has occurred with us but researching this phenoma, this event has happened with other Ford Fusion hybrid owners. We are concerned the propulsion system may shut-down in an unsafe environment and create a dangerous situation!

While driving down the road, my engine lost power. Rpms went down, and the accelerator was not responsive. I pulled the car to the side of the road, and put it in park. The engine idled very roughly. I shut off the car, waited 5 seconds and attempted to restart. The engine did restart after some effort by the starter. I drove down the road, and the car behaved normally. This seemingly isolated incident increased in frequency in the following weeks. Sometimes up to 5 times a day. I took my car to an authorized Ford dealer, and the problem was diagnosed as a faulty throttle body. Cost of replacement is $355. I researched the problem online and noticed that the problem seems to be fairly common among 2010 Ford Fusion owners. The online complaints about Fusion throttle body problems were exactly the same as the symptoms I experienced. The danger lies in the fact that the car basically stalls without warning and must be restarted before normal driving can resume. I have experienced this problem at both highway and city speeds. A stalled engine in the wrong place at the wrong time (middle of an intersection, freeway, while passing, etc.) could have disastrous effects.

I purchased a 2010 Ford Fusion in June and about 3 weeks later, it decelerated and the wrench lit up on the dashboard, while I was driving. Luckily, I was not on the highway or this could have caused a serious accident. I pulled over started the car up and it was fine. A few weeks later, I was 2 blocks from my home and the same thing happened 4 times and continues to randomly happen. The time between instances of this occurring can be minutes, hours, days or weeks apart. I have researched the issue and found hundreds if not thousands of complaints and questions regarding the same issue. I was amazed and appalled that such a common and very dangerous issue has not been addressed with a recall. I did purchase the extended warranty only to find out that the warranty does not cover anything that has to do with what is likely to be causing this issue, which is the throttle body. So until I can afford to get this fixed, I am stuck with a car that I am terrified to drive for fear of causing an accident due to the sudden drop in speed.

I was driving my vehicle on the highway, at approximately 55-60 mph, when I suddenly lost the ability to accelerate. The car stalled, and the wrench light came on. I had to pull over and restart the car. This happened again, the next day. The car also began to shake prior to turning the car off. I have read hundreds, if not more, complaints regarding this same issue. My car is currently at a local Ford dealership, where I was advised that it sounded like the "throttle body". the Ford dealer commented that this is a common complaint among the 2010 Fusion. Again, since discovering this problem, I have read hundreds of complaints online in reference to the same issue. I have filed a complaint with Ford, as this part/defect is not covered under my powertrain warranty, even though my vehicle is only two years old, with 58,000 miles. This is a tremendous safety concern, with car losing all ability to accelerate on a busy highway.
