When accelerating and approaching freeway speed, engine stumbled, preventing acceleration. I let off the accelerator and problem didn't occur again. I reported this to the dealer, but they stated that since the vehicle did not register a code there was nothing they could do. I have since had this happen again on july 17 & 18, 2015, but this time the engine light did come on, so i'm assuming it did register a code.…

2011 f150, 3.5l ecoboost motor, vehicle shudders and loses power during acceleration. Dangerous to try and pass vehicles or even change lanes to pull over as there is power loss from engine. Taken to dealer and they performed ford tsb 13-08-01. This did not fix the problem. The engine misfire continued, after returning to dealer the vehicle showed code related to same tsb after it had been applied. Dealer cleared…

The engine will start to miss badly and than go dead when passing this is dangerous.. There was an investigation by you in may 2013 but you stopped it in 14 because ford said they had a fix for the problem.. The problem is not fixed and this is dangerous. My truck has been to ford 4 times now and they keep changing a coil or spark plug they say. The first time they put some kind of deflector on the charge air…

I experienced lack of acceleration, sputtering, shaking from the vehicle while trying to pass on a 2 lane rural highway. This is second event of this nature and the first since having ford make certain repairs to engine to correct this issue. I have the v-6 eco boost engine. I am unhappy that this engine encounters this problem and it could result in a wreck with loss of life. This should be taken seriously! *tr

I was merging into traffic after picking up my daughter from daycare. I pressed down on the accelerator firmly to gain speed to get into traffic. My truck stalled with a pinging noise coming from the engine and an uncharacteristic black smoke pouring out of the exhaust pipe. Oncoming traffic had to brake to avoid hitting my truck on my daughters side. The truck recovered but only gradually picked up speed with very…

While traveling down the road and the need to accelerate to pass a much slower vehicle my truck lost all power and began shuddering very bad. With oncoming traffic approaching quickly i had to step on the brakes rather hard and quick to avoid a accident. What would have possibly happened if i was towing a legal but heavy load? Ford has a known problem with the coils on the ecoboost and this truly needs to be…

The truck is new to me and will miss in cases of acceleration on the highway or getting on the highway. If it were a smaller vehicle, i know i would have been run over today when trying to enter the highway already at about 60-65 mph and the engine sputtered and felt like it quit and i had to run on to the side of the road to not get hit. It has been sputtering/missing alot but never to that extreme. I hear there is…

Thinking it was a one off i accelerated hard again and again the car stuttered. I went easy for a couple days and then again accelerated hard a few days later with the same result. I got online and realized i wasn't the only…

While accelerating the truck hesitates, looses power and jerks violently, the check engine light flashes several times while passing a vehicle. When the truck jerks and looses power it feels like the engine is about to explode. Has almost caused several accidents because of the sudden lost of power. It appears to me that the truck is misfiring. *tr
