Traveling at freeway speed, engine suddenly lost all power and reverted to idle RPM. Engine was idling roughly, and pressing on accelerator would not increase rpms. The "wrench" (check engine) light was illuminated. Was able to coast downhill to exit freeway; very unsafe condition. Switched off engine, restarted engine... and it ran normal; "wrench" light extinguished. Took car to walnut creek Ford following morning; they said no fault code was recorded on the cars computer and they could not replicate problem. Service rep told me Ford had no records of any previous problems of this nature, so I should just keep driving the car. I told him that was unsafe, and he replied there was nothing else he could do. He said he "could not just throw parts at an unknown problem"'. same problem occurred on Nov 01, 2012. I did an on-line search on various Ford Fusion forums and found multiple reports of this same situation with V6 engine attributed to throttle body housing. Immediately took car to walnut creek Ford and told service manager I would not accept the car until it was repaired. Showed him copies of multiple on-line reports of same problem and told him his rep had lied during my previous visit about Ford not knowing of any previous reported problems. Service manager replied that "on-line reports are not always real", but said he would have his best mechanic check my car. Mechanic found defective throttle body housing and replaced. Have not had recurrence of the engine failure.

Driving normal for around an hr then all of a sudden a lighted wrench shows on dash and the accelerator does not engage properly and car feels like it is very rough and low idle. Power brakes and power steering work fine and can pull over but was in a turnaround for a highway access rd. Turned vehicle off and turned it back on again and it worked ok. Next day it happened twice, one of those times just from the start of turning on vehicle and trying to leave parking lot of work, and second time was on a 45mph rd which felt dangerous. Same thing accelerator stopped working and it coasted down till I could put in park and turn of vehicle and turn back on. It does not work if you are coasting and put it in neutral and turn off and on as the problem is still there. Afraid of it happening on highway. Seems like a software or sensor issue with throttle body as when you do give it gas on the peddle it feels like the throttle plate is blocked or trying to open up but not enough to go just small weak spurts.

2nd incident w/ gas peddle stopping working while driving w my children in the car. Wrench light came on and I put on my flashers and turned off ignition due to burning smell coming from under the hood should note every time this has happened I have just put gas in my car as well, also had to have a new battery put on my 1yr and 10 month old car today. Restarted the car and was only luckily 100yrds or less from my driveway so will call and have car towed to dealership again. Car is not safe for me and my family!!!

While travel ing up a busy hwy in around 2 in the afternoon, the gas peddle quit working and car started to violent shake. At the time of incident I was traveling at 45 mph and could have been seriously injured. Pulled to the side rd. Put the car in park and turned off the ignition and restarted the car and gas peddle worked now and I drove it to dealership where they kept it for six days and did not do any repairs on it.

Made 10 mi trip to school. 1/2 - 1 hr later, made 1/2 mi trip to store. On return to school on highway lost throttle response until car was turned off and restarted. (wrench light on dash displayed.) 2 hrs later, lost throttle response when turning onto highway from school. Car responded as normal after restart. Ford dealership replaced etb, A71, gasket, and throttle body. Car has returned to normal function.

As we were traveling we suddenly began slowing to a halt. Though my husband was pressing the gas pedal and the engine was running, there was no response. Luckily he was able to steer the car to the shoulder before we stopped completely. We were on a sparsely traveled road at the time. After checking under the hood, repeatedly trying to push the pedal and calling roadside assistance, he finally turned the engine off and then restarted it. The throttle seemed to work fine and we continued to our destination. The following day the same thing occurred. Again we were not in heavy traffic and there was a shoulder available for us to get to. This time he immediately turned the engine off and restarted it with everything returning to normal. We were very fearful of this occurring in heavy traffic or where there was not a shoulder available. We took the car back to the dealer where they charged us $387.43 to replace the throttle body #ds7Z-9E926-a.

While driving ~55mph in left lane of a 3-lane interstate at morning rush hour, the engine lost power, continued running at ~1000rpm, but would not accelerate. The check engine and wrench lights were on. The car was nearly hit by numerous vehicles as I coasted to the emergency lane on the right side of the expressway. The engine was shut off, then restarted, and it was ok for several miles. The same scenario was repeated twice while driving to a nearby dealer. The throttle body was replaced at a cost of $650 since it was out of warranty. Service personnel told me that they had seen several of these same problems on Fusion. This one dealer is most likely representative of others, so there must be a very large number of these problems occurring in nearly new vehicles. Why hasn't Ford, where quality used to be job one, issued a recall? this car has been otherwise flawless up to this point.
