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.

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.

Was driving on a state road going approximately 40-45 mph. Began to accelerate to go up an incline and then engine sputtered and then shut off. Same thing happened a week later going about 5-10 mph while accelerating from a stop sign on a residential street. Took the car to the dealership and the problem was a bad throttle body which was replaced.

- Cheshire, CT, USA

Wrench light came on the car slowed down shake bad and no throttle response at all, had it towed in for service and was told it was a throttle body assembly failure, not covered under power train warranty.

It first happened on Tuesday September 3, 2013 while driving on a main road returning to my home. The speed was 50 miles per hour and all of a sudden a wrench tool light shines and my car just slows down to 5 miles and then stops. Luckily it was late at night and I was in the right hand lane and could turn into a driveway of a car wash. It was a scary thing and I was all alone. I turned off the car and sat for a minute and then turned it back on. I was able to go 1 mile to my home and park the car. I thought it might be a fluke. I didn't drive it again until Thursday when it occurred on the same street close to the same place. I was almost rear-ended by a car behind me. On Saturday, I was traveling the toll road and going 65 miles per hour trying to get to a bible study when it just slowed and quit. I had numerous cars roaring around me. I stopped the engine and started it again. It did it 3 more times before I got to my location. After my meeting I went directly to my Ford dealer. I had to rent a car from the airport because their service was closing and they couldn't start on it until Monday (today) September 9th. I found out it was the throttle body and that it wasn't covered under my power train warranty. With my senior discount it is costing me $595.84. I have only had this card for 16 months. It had 39K miles on it when I bought it. Now I see this thing has happened to many more cars. When is it going to stop? Ford must do something about this.

The contact owns a 2010 Ford Fusion. The contact stated that while driving 70 mph, the vehicle began to decelerate independently. The manufacturer was notified of the failure. The vehicle had not been repaired. The failure and current mileage was 50,000.

I was travelling on an interstate doing 70 miles an hour when my car made a bang and I lost all throttle response. The car was running, seemed to go into neutral but pressing the gas pedal did nothing. I was able to cost over 4 lanes dodging traffic to get to a spot where I could come to stop. After turning off the engine and restarting everything went back to normal. Now just over a week later it happened 3 more times in 1 day. Doing research it seems this is a common complaint from Fusion and escape owners. It also seems there may be an investigation under way as to whether this should be a recall issue. Now if Ford was to fix this it would be 1 thing, but after almost killing me on the interstate I now have to fork over $400 to the dealership because even though my car is several thousand miles short of the 30K mile warranty, the 3 year stipulation on my warranty ended less than 3 months ago.

Upon accelerating from stop at city intersection to 30 mph, car suddenly lost all acceleration. Coasted into nearby lot. "wrench" light on. Turned car off. Luckily, no car had been approaching from rear, and this was before entering ramp to busy 60 mph highway. Car ran, as if normal after re-starting, wrench light out. Drove 15 miles to dealer service shop. Shop performed Ford's throttle body test procedure and verified throttle body had failed. Shop replaced electronic throttle body assembly; car at 54,000 miles. From researching, see that this a prevalent issue with increasing rate of occurrence (a top 5 car complaint over past 90 days). Given the apparent incident rate, intermittent nature, and odds of occurring with sudden surprise in traffic moving at speed, clearly presents a hazardous condition and compromises safety in otherwise normal driving circumstances. Evidently problem occurs within predictable range on odometer, which probably indicates some manufacturing defect leading to premature failure. Along with the resulting safety risk exposure, this does not reasonably meet automotive consumer expectations for the equipment and technology. As more vehicles go through this mileage range, may become epidemic with increasing odds for bad outcomes. Wanted to add my event to the list; maybe can save someone else potential serious accident and injury. To this point, the car seems good otherwise, but this item needs to be taken seriously and by all rights get remedied in a proactive manner.

While accelerating heard a clunk and lost all power to the transmission and throttle. Throttle light came on, car ran rough. Had to coast to the side of the road. Turned car off and back on. Car ran fine, light went off and I continued home. Now it happened again last week while going 65 on the interstate. Same scenario. It happened again yesterday and twice this morning. Cruise was set the last 3 times, going 68 on the interstate. Last time in addition to the throttle warning light the check engine light came on and stayed on even after restarting. This could have been bad on the interstate, but there wasn't much traffic. It is now at the shop waiting on the verdict.

Driving along and vehicle lost power. Pulled over and turned of vehicle. Waited 1 minute and started vehicle up and was able to drive again. This has occurred at least 15 times since the first time and most of them occurred while I was driving on the interstate. Always had to pull to the side and shut the vehicle off, wait a minute and start the vehicle back up and can continue on. No pattern except outside temperature was above 80 degrees.

- Palatine, IL, USA

Car engine shut off at 40 mph, step on gas nothing happens. Car jerks and sputters. Must pull to side of road and shut off engine. Wait 2 minutes and try to restart. Returned to dealer without success 3 times. Car has shut off 6 times since at different speeds and heavy traffic. A real safety hazard!

The vehicle was coming to a stop and the engine lost power and stalled. This has occurred two time in the past 4 weeks. The vehicle had been driven at least a few miles before this occurred both times. Put the vehicle in park and it started immediately and I was able to drive away. The vehicle appears to not be idling to slow.

Engine dropped to 900 RPM. Coasted to stop. Vehicle would not respond to acceleration. Turned engine off and restarted made it to town. Diagnosed by dealership as throttle body. Parts not available till October. They have car we have rental because we had extended warranty. If we didn't have that we would be in trouble.

- Topeka, KS, USA

Just four months after purchasing my so called "certified pre-owned 172 point pass inspected 2010 Ford Fusion" the car starts acting up while driving down a main street in the middle of town, the car lost all acceleration right after I started taking off from a stop light. The wrench light then came on and the car started to stall out as this was going on I'm also trying to turn left, which was a little scary because I basically cut someone off while turning because, I had no acceleration whatsoever to avoid them. This is a serious problem and I'm not the only one whose had to go through it from all the same complaints I see on the internet. This malfunctioning throttle body needs to be recalled before someone gets seriously hurt!

Driving on highway, traveling at appx 65-70 miles per hour - car started rattling and then slowed down considerably - car did not stall, but pressing on the gas pedal and the car did not accelerate. Was able to safely pull over, turned the car off, tried to drive, but the car wouldn't drive - engine worked fine, but car would not move forward or backward. Yellow wrench light came on. Had car towed to dealership. Was told it needs a new throttle body assembly.

- St Clair Shores, MI, USA

While on the freeway doing approximately 65-75 mph, my vehicle lost power, the wrench light came on the dash, and the vehicle began to stall. I pulled over to the side of the freeway, turned the car off, and restarted. It was fine after restarting. A couple days later the incident occurred again. Within 4 days, my vehicle began to have 4 episodes on my 11 mile commute. These issues during rush hour traffic prompted me to bring it in to the dealership asap as I did not feel safe driving it any longer. My vehicle is currently at the dealership awaiting diagnosis and repair. After a google search, I am fairly certain that the diagnosis will involve the throttle body.
