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 6-cyl

  • 35,000 miles


On three separate occasions around the incident date, my 2010 Fusion had a sudden loss of power accompanied by a rough idle. The "wrench light" came on during each incident. Each time I moved the car to the side of the road, shut it down and restarted it. Each restart took a prolonged time before the engine would turn over. After each restart, the car ran fine. The first time the incident happened I had a vehicle behind me and was nearly rear ended. I ended up taking the car to the dealership for repair. Dealership was unable to duplicate the problem. Given the information about the malfunction symptoms as well as the triggering of the "wrench light" I was able to provide, the service advisor along with the lead technician agreed that the throttle body was the likely problem and performed the repair. Due to the fact the car was approx. 3 months past the 3yrs of the 3yrs/36K warranty it was not covered. This repair was also not covered by the epa or power train warranty nor was it a covered part on my extended warranty. This resulted in a repair being paid out of pocket. It does seem likely that Ford Motor Co. Is aware of this problem as the replacement throttle body has an updated part number (part # ds7Z9E926A) from the original listed part. This information about the updated part number was provided by the service advisor at the dealership. In addition to the throttle body being replaced, an update to the vehicle computer was also required. Since the writing of this complaint, the car has not had any further incidences of loss of power.

Fusion 4-cyl

I was driving through a busy intersection when there was no throttle response at alll. I managed to pull over to the side of the road and shut engine off. Waited a few minutes and restarted engine again. Had no problems for the rest of the day. That evening me and my young son were going out for dinner when I tried to merge into fast moving traffic the throttle response was not there. I had to swerve sharply to the right to avoid being rear ended by a semi-truck going 65 miles an hour. Needless to say I had the vehicule towed to the dealer for repairs. The 3 year warrenty had exspired but the vehicule only had 25000 miles on it.I was quoted around $600 for replacement of the throttle body. This part should not have failed within the amount of miles that wee on it. I feel that Ford Motor Company knows about this problem and is waiting for someone to lose their life before they have a recall on the part.

On the highway with my little girl in the back going 65 mph, then suddenly the car went limp, lost all power. I barely made it the shoulder. I was so scared I took my daughter out the car and stand her on the far side of the road. The car was idling very rough, with the service engine wrench on. I had it towed, but I could have saved some cash because after restarting the car it ran fine. The dealer said they could not find anything wrong ┐┐ no error code, they test drive it and could not duplicate the issue. Turns out if you shut the car off it clears the error code, how stupid is this! who is going to keep the car running while getting a tow. I drove it for about a month then it happen again, and sure enough on the highway again. I took it back to the dealer and from my research on the web I told them to change the throttle box, ┐┐ let┐'s hope this fix the issue.

This is the second time my 2010 Ford Fusion stalled while driving on the freeway. The car will just start limping and will not accelerate. Once I maneuver the car safely onto the side of the freeway and turn the car off I am normally successful in restarting the car and resuming my commute. The check engine light will stay on, and once you refuel the vehicle all symptoms and warning lights are no longer present. This problem is an obvious safety hazard and needs to be addressed by Ford's engineers.

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?

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!

Fusion 6-cyl

  • 66,955 miles
I have had this problem at various intervals since February of 2012. My Fusion would stall an would not accelerate when I left from a stop sign or a traffic light, the vehicle would not go above ten miles per hour an the wrench light would come on my instrument panel. I would have to get off the road an cut the car off then restart it. The car would act like it had flooded an lurch an jerk, when before I would have it come to a complete stop. I took it to the dealer I purchased the car from an I told them about my incidents of the same type each time. They could not locate the problem until on June 30,2012 where the same problem happened to me an I drove the vehicle directly to the dealership. They were able to diagnose the problem as a faulty throttle body. They told me I must have been using some dirty fuel since they said the throttle body looked black inside of fuel. I had used exclusively 93 octane fuel into my vehicle. I had purchased a extended warranty when I purchased my vehicle from preston Ford in which they told me when I first took the vehicle there with the same recurring problem, they said it was covered under the warranty. It was then they told me the warranty did not cover that part. I had to pay for the faulty part with a total bill of $593, along with other items I had for this service visit. I have not had a problem since this work was done on my vehicle. They did not tell that Ford had issued a technical service bulletin on this problem that was known by the dealership, but I had to pay for this to tell me that I had one of the vehicles that were within this bulletin.

Fusion 6-cyl

  • 67,400 miles
The first instance I was driving as normal in my vehicle and with out warning going 50 mph my car shut off with no power or ability to do anything besides to try and coast off the road and out of harm. A wrench light flashes when it occurs. The second time I was making a turn at approx 20 mph in a four way light intersection and lost power over the car again with a wrench light appearing again. The only way to gain power again is to put the car in park turn it off and wait a bit to restart the vehicle. When you restart the car the wrench light is gone and the car acts like there was never a problem and runs smoothly. After a 2 day diagnosis by Ford they state that the throttle body is the cause of the problem. In total I have had this happen 5 times with out any warning going various speeds and luckly avoiding multiple accidents. Like mentioned above after starting the car the wrench light disappears performing as usual.

First incident: Vehicle was traveling about 40 mph and would not pull up a shallow grade hill about 1 mile from the house. Car was started "cold". wife pulled off road and engine died. "wrench" symbol came on dash. I arrived about 15 minutes later and started car to move it further off the road. It ran so I took it back home, no apparent issue. Called dealer and got it in the next day. Dealer is about 2.5miles from my home. Dealer could find nothing wrong and we drove it home. Did not drive it for about a week. Second incident: Wife at a busy controlled intersection. Car would not accelerate when light turned green. Called me after getting car started and moved to a safe location about 1/2 mile from intersection. "wrench" and "battery" lights came on dash. About 2 hours later we took the car to the dealer with no apparent problem. Dealer informed me the computer coded a throttle body issue. Throttle body changed. We have not driven the car over 10 miles since then. Wife no longer trust car.

Fusion 6-cyl

While driving on a major highway in the fast lane, the fuel seemed to suddenly cut off. There was no response to the gas pedal. The engine was running at idle and the car abruptly slowed down forcing me to pull over. This was quite frightening due to the fact that I was in the fast lane and needed to get over to the right shoulder in a hurry. After turning on the flashers and turning off the engine, my wife reminded me of this incident occurring twice before to her recently but on local roads. We had brought the vehicle to Ford and they didn't find anything wrong. After a minute or two I started the engine and proceeded to move the car and realized that the engine was now responding to the gas pedal. I drove home and brought the car directly to the Ford dealer.they ended up replacing the throttle body which costs us $497.79. They said that it was not covered by Ford's emission warranty (5 yr/ 50,000 mi). I believe that this is a safety issue that can easily lead to injuries and possible fatalities unless it is immediately addressed. This should be a recall!

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.

Driving at 40 mph engine went into "limp mode". the engine remains running, but no power. Pulled over and shut engine off. Restarted and ran fine except the problem recurred several times over the next few days at all different speeds. Losing power and/or speed at highway speeds or in traffic could prove to be very dangerous. Took the vehicle to a Ford dealer. They informed me that the throttle valve was sticking and the throttle body needed to be replaced. I was also told that this occurred because of the gasoline additives that the federal government mandates, but now I am hearing that it is probably from a defective circuit board. Very expensive repair for a fairly new vehicle. Problem has not happened since the repair was done.

  • 27,000 miles
The wrench light came on and stayed on steady and the car suddenly lost all engine power. Headlights stayed still on and hazard lights worked. I tried starting the car but pressing the gas pedal produced no movement of the car nor any increase in engine sound. After trying to start it several times, it seemed like it started but not a normal start. The engine appeared to be very rough but again, no fast engine sound. It kind of limped to the side of the road which was on a very slight incline. No pressing of the gas pedal produced any significant movement of the car. The car was violently shaking as it limped to the side of the road at maybe 2 miles per hour. Once I got it to the side of the road out of traffic, I did turn it off. I gave it about 30 seconds and it started normally. No more wrench light. It seemed to work fine after that. I drove home " about 90 miles with no further problems. I reported the problem to our local Ford dealer. The dealer has been supportive. Ford Motor Company has not been supportive. When I called the Ford dealer explaining the symptoms, the service coordinator?S first question was, ?is it a Fusion?? he already knew it was a common problem with Fusion. He said that I am not going to like what he had to say. He said that Ford will not allow him to do the 30-minute repair unless a code is available in the obd unit. I brought it in and no code was found. They tried for two days to get it to code. The service manager pleaded with Ford?S upper level to allow the repair but they were inflexible. Their response ? ?no code, no repair.? Ford"S customer relationship center was useless! they offered no help. The local dealer had six cars the week after my car died with the exact same issue as mine. I was placed back on the road with Ford knowing I would again be stranded. It happened again 4 weeks later.

While driving home the vehicle lost all acceleration and the wrench light came on. The rpms dropped to below 1000. I was able to safely pull over where the car shook and died out. I attempted to restart the vehicle and it would not start. I waited a few minutes and was able to get it started.

While driving under normal conditions, at approximately 45 mph, engine suddenly stalls, wrench light comes on dash board, no power to engine whatsoever. Pulled the car over onto shoulder, engine is shaking violently at this point, shut the car off. Waited approx. Five minutes, turn car back on, no problem. No more wrench light, no longer stalls. I took the car into a Ford dealer and they said I had a bad O2 sensor. So they replace it and say that will fix the problem. When I dropped it off I told them to look at the electronic throttle body because a lot of people online had posted about the same type of problem and the throttle body was to blame. The dealer told me they checked the throttle body and it was fine.Ł ha!! however approximately 1-2 weeks go by and the same thing happens again with no warning. Driving down the road everything is fine and then suddenly the car stalls, no power to engine, shaking, wrench light comes on again. This happens 3 times in a span of about 7 miles. I bring the car back to Ford and tell them what happened. They call me back a few hours later and say yeah you've got a bad throttle body (but it was "fine" two weeks ago?) they then proceed to tell me that it will cost approx. $465 and it's not covered by any warranty. I also spoke with the dealer that I purchased the car from and they told me over the phone that they were getting a lot of these 2010 Fusion with faulty throttle body parts and that if I had it replaced it would actually be a different design than the original factory installed version. Yet I had to pay to have it replaced.

I was slowing down as the traffic light turned red. The engine stalled and cut out. The wrench warning light came on. It took several tries to get the car started. Over the next several days, the car stalled while we were driving on a major highway in traffic at 45 to 50 miles an hour. We took the car to a Ford dealer who diagnosed the problem as a short circuit in the throttle body and motor assembly. They replaced the parts at a cost of $438.64. We have since learned of other Ford of the same age having the same problem.

  • 52,000 miles
At approx. 52K while drive approx. 40mph, all fuel power was lost and 'wrench' light came on. Had to coast to a stop, car sputtering. Put in park and killed the engine. Waited a minute, car started with some hesitation. Ran diagnostic, nothing. About an hour later, ran some B-12 through fuel; cured. Twice again at approx. 56K, same thing (once at 70mph on the interstate and the other at 55mph on a busy highway); ran B-12 both times. On third event, it finally gave a reading - throttle body stuck in open position. Brought vehicle to Ford dealership, they got the same reading and changed the throttle body to the tune of $350. Ford stated there was no technical service manual indication of problem forcing a possible recall. How lucky for me and my kids that we weren't in a high-traffic situation and I could safely maneuver to the shoulder...all three times!

  • 45,000 miles
We were driving around 50 mph when the car stopped accelerating and we slowed down to 5 mph.the wrench light and check engine light lit up. Luckily, there was nobody on the road behind us or we might have been killed from the sudden change in acceleration. We were told by our dealer that the throttle body needed replacing. They replaced it but the check engine light is still on. It was not covered by warranty (I was told by Ford customer service that no warranty covers that part). How convenient that they specifically don't cover a part that is clearly defective. I am not sure if anyone has died from this problem, but I have two teenage sons who drive that car and I don't trust it anymore. After reading all of the complaints on this site, and elsewhere, I demand that an investigation be done into this faulty part before someone is injured or killed. Thank you.
