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

  • 49,900 miles


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!

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.

Fusion 4-cyl

  • 30,000 miles


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?

Fusion 4-cyl

  • 40,115 miles
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.

Fusion 6-cyl

  • 29,270 miles
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!

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.

Fusion 6-cyl

  • 41,413 miles
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.

Fusion 4-cyl

  • 39,278 miles
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.

Fusion 4-cyl

  • 78,000 miles


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.

I was on the freeway when engine speed suddenly went to idle. I was in the middle lane and almost got into a crash trying to get to the road side. When I brought the car to the Ford dealer they said the throttle body was bad and it cost me $500 they said it was not covered under the power train warranty, go figure. Also the transmission does not down shift properly after heavy acceleration, they said it was normal. It's no wonder why people shy away from so called american cars, it will be my last.

While driving on I-49 so., approx. 60 mph in peak morning traffic, the engine stalled. Luckily I was able to pull over to the shoulder. Noticed a "wrench" icon lit on dash. Turned off engine and after a few minutes, re-started engine. All clear on dash, so continued on to work. Called hub city Ford and brought car in the next morning. The "throttle body" was changed. No other warning or lights came on.

Fusion 6-cyl

  • 30,000 miles
As I came to a full stop at a signal the car completely died - no lights displayed on the dash. Second time I was making a right hand turn at approx 5-10 mph and it died as I came out of turn. Both times it started right back up. Ford dealer did complete check and extended road test on 2-5-13 but could find nothing wrong and there were no computer errors generated. Both incidences the failure occured during heavy traffic on major streets within the city. My concern (other then it dying) is that nothing lit up or displayed on the dash to indicate the engine was not running. It wasn't until I put on foot on the gas pedal I realized it was not running.

I was driving on the highway at a steady speed when all of a sudden, the gas pedal stopped responding, almost as if I was in neutral. I was able to get over to the shoulder. It took a few tries of restarting the car in order to get it going. The same incident happened again the next week.
