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.

  • 58,467 miles


I was merging onto the highway and when I hit approximately 65 mph, I felt the lose momentum and by the time I looked down, I was around 55-60 mph. I then tried to give it gas while watching my RPM's and saw that it was erratically jumping around between the 1000 and 1500 marks. So I pull over to the should and off the road and as I start coming to a stop, my car beings to shake violently. So I throw it in park and immediately turned off the car. After about 10 minutes on the phone with the closest Ford dealer I know, I turn on the car and it's running like nothing ever happened. However, it did take a little long to start, like as if the battery was on the verge of dying. I managed to get my car to the Ford dealership where I had them run a diagnostics test on it and sure enough, they didn't find a code. They even had me come out and watch the test be done, and everything was showing a passing mark.

  • 39,542 miles
While driving on the interstate at 60 mph, my car started to decelerate. My car dropped to 1100 rpms and was unresponsive to the accelerator. I was able to coast to the side of the road before getting ran over. The check engine light was not on, but the wrench light was lit up. Once I turned off the car for 3 seconds and restarted my car, the car started to work again. When I called the dealership they informed me this is a common problem, but no recall has been issued and its not part of the power train warranty. The power train warranty on covers the block, heads and transmission. The cost to have this fixed is about $450. I never expected to be doing this types of repairs on a car with only 39,500 miles.

Fusion 6-cyl

  • 42,932 miles
Car lost all engine power and would not accelerate going down the interstate. Car was jerking and shaking. The car had a "wrench" light on the dash. Engine codes were P2111 and P 2112. After researching online, the issue is the throttle body. It is a sealed unit and must be replaced.

Car idling rough, engine stalls multiple times when at idle or slow (parking lot) speeds. Multiple occurrences over several days. Read that it was a very common problem with these Ford Fusion cars, being the throttle body. Verified with mechanics. No trouble codes given by on board computer. Several days later, engine stalled while driving on the interstate at speeds of 65-70mph. This has continued happening from time to time, even after cleaning of the throttle body that is on national backorder. Idle issues also continue. Still no trouble codes given by the on board computer.

Fusion 4-cyl

  • 55,000 miles
I was turning left into a driveway and my car lost acceleration but did not quit running. I pulled over to the side of street and turned the car off for a few minutes and the car started back up with no problem. There was no check engine light or any other indicator that something was wrong. It happened again same day same thing. It worries me that I might be killed the next time. I called the Ford dealership and was told this has happened to several of their customers but no recalls are on record. This is very dangerous and Ford should take a close look at this before someone is killed or seriously injured.

problem #498

Sep 062013


  • 88,900 miles
While driving upon four occasions, the engine stopped, resulting in a loss of speed and pulling over to the side of the road amid traffic or a driving lane closest to the curb. I was unable to accelerate, turned on my hazards and slowly maneuvered to a stop. The "wrench" light immediately illuminated, which normally indicates a powertrain issue; however, during the 4th occasion, the wrench light went off and then the "check engine" light illuminated. After speaking with several service personnel members and receiving guidance, it has been determined to be the electronic throttle body. While questioning my vehicle's service concerns, I encountered another individual at my dealership with the same car and issue, which was solved by replacing the electronic throttle body. After the first incident, I let the car rest for 5 minutes, started the car back up with ease and without the same issue for 7 days. The subsequent incidences occurred within a 3 hour period. Although not on the highway each time, I feared a severe accident and stuck to city streets.

Fusion 4-cyl

  • 58,620 miles


While driving approximately 40mph on a six lane divided road, the wrench caution light appeared (indicating transmission/throttle malfunction). The engine RPM immediately dropped and began fluctuating around 1,000 and the vehicle began to shake violently. There was absolutely no response to accelerator inputs. The driver was able to maneuver the vehicle clear of traffic. The maximum speed that could be attained at the fluctuating RPM was 14 mph. It is a miracle the vehicle was not in rear end collision as the posted speed limit was 45mph. Car was allowed to idle at the reduced RPM while driver inspected the engine and pressed the accelerator. The car was turned off and back on (with a little bit of trouble turning over). The incident occurred once on 26aug2013, four times on 13sep2013, and once on 14sep2013. The car has not been driven since the last occurrence. The vehicle was taken to a mechanic who recommended taking it to a Ford dealership due to only having 1,400 miles left on the powertrain warranty. The service department was able to pull P2111 code. After receiving an exorbitant quote for the repair ($230 for part, $280 for labor) with no estimated delivery date for the backordered part, the repair was denied to allow for further research. The dealer has absolutely no qualms releasing the car with a known malfunction, presenting a hazard to the driver and others on the road. A car that immediately decelerates should be considered as dangerous as an uncommanded acceleration. To prevent serious injury/death, Ford should issue and immediate recall for the failing throttle body.

  • 110,000 miles
I was driving home from work when my car stalled and a wrench light came on. I immediately pulled over to the side of the road, turned the car off and on, and drove to my mechanic. He drove around to try and re create the problem. After 100 or so miles it happened again and it turned out to be codes P2111 and P2112 which turned out to be throttle body codes. I had to pay to get the throttle body replaced because it is not covered under any warranty and is not a recalled part.

We were driving up a slight hill on a state highway with a 45 mi/hr speed limit when the car lost power and the yellow 'dogbone' wrench warning light illuminated. I pulled to the side of the road, turned the car off and restarted it, and continued to drive to our destination. Coming home, the car failed again, and so once each of the next three days. We took it to our dealer and had to wait a week for a new throttle body to be delivered.

While driving with my family (3 yr old, 6 month old and my husband) throttle sudden stopped functioning. We were driving on the freeway when this happened the first time and was very scary and dangerous to suddenly lose speed. When we pulled over and restarted the car the throttle response seemed back to normal. We have had this happen multiple times a day ( as this is my families only car) I am now scared to drive with my girls in the car.

This is the third incident (different days) where I've been driving and the car starts to lose power. The wrench light came on and the car stutters and loses power. The past two times (different days), it happened once and I shut the car off and restarted and it was fine. Today I went 3-4 miles in the city and it happened 5-6 times in a short period. I have a scheduled appointment with the Ford dealership in our area. They said they do this same repair (throttle) 2-3 times a week. I am very frustrated and disgusted with Ford. There have been numerous reports and still no recall. Are they waiting until someone gets killed before they will do something? the dealership said it would cost about $500 and luckily they have the part in stock.

Fusion 6-cyl

  • 56,322 miles
Driving to work on a busy highway, going approximately 62 miles per hour, when my car just started to die. I went from 62 miles per hour, down to about 5 miles per hour in a few seconds, my wrench warning light and check engine light were on, I cannot believe that I was not rear ended or that I was not the cause of an accident. I pulled over to the side of the road as best I could, turned the car off. When I restarted it and tried to move, it chugged and there was not any power. I sat for about 15 minutes, and tried again, I was able to get another couple of miles to work. I took my car to the dealership and they stated that it was the throttle body, the cost is $425 plus tax to fix, made me sick. After seeing all of the complaints about this, I cannot believe that the throttle body is not a recall item, it is truly a safety concern. My car is a 2010 Fusion, I had to spend $325 at 30,000 miles for new rotors, so this really is upsetting.

Wrench light came on and vehicle immediately lost power. This happened twice on the freeway. Luckily we were able to pull over and no accident occurred. Managed to stop car / restart and made our way to the dealership. They replaced the throttle body. Vehicle was just past the 3 year/36000 warranty period. This is very dangerous and we were very lucky to not get slammed in the rear from these incidents. This is apparently happening with a lot of 2010 Ford Fusion.

Fusion 4-cyl

  • 67,850 miles
Ongoing issue with acceleration developed into a malfunction in the throttle body. I had noticed intermittent stutters during acceleration and deceleration. This time, the car lost power to accelerate, vibrated violently, and forced me to pull over for fear of causing an accident. Now it is recurring and although the code erases and it seems to be fine, it will suddenly fail to operate properly and cause me to cut out of traffic as quickly as possible.

My car died out in the middle of the road after picking up my daughter from school. Luckily no one was injured... yet. There are thousands of reports of this same problem and Ford acknowledges the part as defective, although there has been no formal recall. Hopefully Ford will do right by the american people before a horrible tragedy befalls a family due to their negligence.

Fusion 6-cyl

  • 52,000 miles
I was traveling on interstate at 65-70 mph, when my Fusion's RPM's all of a sudden dropped to 1 and would not react to the gas pedal, luckily I was in the slow lane and managed to coast off the interstate. Fortunately for me this was during non-rush hour traffic, otherwise it could have been quite dangerous with not being able to get out of the way of continued interstate traffic. After turning the vehicle off and sitting for a few minutes, I was able to start the engine and continue to my point of destination. I googled the problem and found that the cause is a faulty throttle body. I called the local Ford dealership, where I was advised the part was on a lengthy back order and due to me being just outside my warranty, the hefty repair cost of between $500 and $600 would be my responsibility. This is a known party failure on many Ford and it appears they've even redesigned the part due to the issues. There is currently an open investigation with NHTSA on this issue. Hopefully it will not take something as serious as a fatality for Ford to see they need to have an immediate recall. I have had the incident occur two more times since the original incident date. Once again on interstate at interstate speed and once in city driving, it occurred as I was pulling out from a parking lot, against traffic onto a major city thoroughfare. Again, fortunate for the lighter traffic time and the ability to coast to the center turn lane to turn the vehicle off and wait to restart. The dealer has scheduled to diagnose the vehicle and charge me $95 for what they have already advised me over the phone. As for resolution, I am among the many who are at the mercy of shipping schedules of this necessary, apparently, illusive part.

Car would stall while driving and the wrench and engine light would come on. Went to autozone to get a free engine check code. It was P2111. Upon further research, looks like Ford had released a new throttle body part in its new versions without doing a recall on its past versions. Hopefully this can help saves lives incase someone gets stalled on the freeway going 70mph +.

  • 52,000 miles
While going to first to second gear the engine suddenly shudders and I lost power and the "wrench" symbol on the dash came on. The engine was still running, very roughly, but would not accelerate. The brakes still worked and I pulled over. I was able to restart the engine with some difficulty. This has happened four times. The first time I thought I was in too low of a gear and stalled it. But since I realized it has only happened while accelerating and going from first to second gear.

Fusion 4-cyl

  • 39,000 miles
Second engine/power train failure within 4,000 miles of vehicle 36 month, 36,000 mile warranty expiration (first failure was a total power loss at high way speeds within 1,000 miles of warranty expiration). Vehicle suddenly began jerking, shuttering and hesitating upon first acceleration. Ford evaluated mass flow sensor to be faulty and replaced at $425 cost in addition to $50 rental car. Upon consultation with Ford customer service, no costs were covered or reimbursed. My wife often travels alone with my children, so we purchase new cars specifically to avoid such break downs and maintenance problems. We paid cash for this vehicle, and could buy a new BMW 760il tomorrow free and clear. Instead, we bought a Ford Fusion to show support for the american auto industry. Understand that mechanical failures happen, but very disappointed with Ford customer service for not reimbursing or issuing recalls for these known manufacturer defects occurring on essentially new first owner cars < 40,000 miles. Will never buy a Ford again.

Fusion 4-cyl

  • 37,000 miles
While driving on the highway, vehicle experienced immediate, sudden and complete loss of engine power (engine would not respond to throttle depression and remained at idle) with associated yellow maintenance wrench illuminated on instrument cluster. Driver had to execute a dangerous decelerating 4 lane change to stop vehicle on a limited and narrow shoulder. After restarting vehicle, the light disappeared, and the vehicle was able to be driven before same mechanical failure occurred after 1 mile. Vehicle was driven 10 miles to nearest Ford dealer at slow speeds and back roads. Power loss occurred approximately 8 more times while enroute to dealer. Extremely dangerous and insidious mode of failure without warning. Could have easily resulted in a fatal crash if it had occurred during a highway merge or crossing traffic situation. Conspicuously convenient timing of failure 2 months and 1000 miles after warranty expiration. After dialogue with Ford customer service, Ford did not reimburse or cover any of repair costs.
