Vehicle experienced hesitation when trying to accelerate. Vehicle experiences jerkiness and at times complete power loss when trying to accelerate. Vehicle lurches and hesitates when trying to maintain speed going up hills, or when trying to accelerate like when passing a car or on an interstate on ramp. Issues have been reported to Ford numerous times over past 2yrs, several various excuses provided and an occasional 'attempt' at fixing, with no remedy. Most recent event (Sep 2013) involved a near crash due to vehicle rapidly losing power in busy traffic. Other incidents in the past have included stalling in the middle of an intersection when trying to accelerate from a full stop and nearly losing control when pulling a boat/trailer and the vehicle began to lurch/jerk when going up hills.
During passing or pulling out in traffic the truck will loose power and misfire this is dangerous because you never know when it will do it. This weekend I was pulling a camper in the rain and it done it five times you have to pull over on the highway and start over when there is no one in sight and also try stopping on the interstate in the rain and pray no one hits you with your family in the vehicle. And this truck has been to the dealer fifteen times for repairs with only 15,000 miles on it.
The vehicle experienced a rough idle then upon acceleration, severe shuddering and lack of power. Check engine light turned on and began flashing. Vehicle is equipped with a 3.5L gtdi engine. Vehicle then continued to experience complete lack of power and shudder while being driven to the dealership.
The contact owns a 2011 Ford F-150. The contact stated that while driving 62 mph, the vehicle began to shake violently and decrease speed. The check engine light illuminated simultaneously. The vehicle was not taken for inspection or repair. The manufacturer was not notified of the failure. The VIN was unavailable. The approximate failure mileage was 40,000.
Departed eureka, ca at 1600 in heavy rain on Friday September 20, 2013. Eureka to redding ca on highway 299. Rain was heavy for about 100 miles northbound on highway 299. At about the 100 mile mark, I attempted to pass another vehicle (sudden acceleration) when the engine began to rapidly lose power and the truck started to shake violently and shudder. The engine light on the dash began to flash. At first I thought it was a flat tire. Because I was in "the middle of nowhere" I continued on towards weaverville. I was climbing a steep hill, slowly and the truck continued to shake and shudder for about 6 miles until I got to the top of Oregon hill (summit). When I reached the top, I put the truck in neutral and carefully coasted down the hill. Within 2 miles (of coasting and the road is dry now) the flashing engine light went off and the truck appeared to return to normal operation. After this, I continued my travel to reno, Nevada and had no further problems. The truck is running fine right now.

As we were driving through lexington Kentucky on rt 75 North, towing our enclosed car trailer with our mustang inside. It was raining pretty hard and there were 4 lanes of traffic on a rather steep grade, the truck went into limp mode as we attempted to change lanes on the freeway to allow traffic to merge from an on ramp. I had just read about a few incidents where this same thing had happened to others before we had left on this trip. The truck dropped to about 30 miles per hour, I had to maneuver to the right shoulder in heavy traffic towing a 20' long trailer in a heavy rain storm. We stopped the truck, shut it off, as described in the forums I had read about this same problem, and let it set for about 15 minutes. It restarted fine and ran good the rest of the way back to Ohio. When we returned home I took the truck into the dealership we purchased it from and they said because the computer showed no codes there was nothing wrong with the truck, I was prepared for that with the articles that I had read and I said fix it or I'll file a suit against the dealership and Ford! the mileage had dropped from about 16-17 mpg in the city to about 11 mpg in the city, it took them supposedly until August to "get the parts in" so far it's been fine but I haven't had an opportunity to duplicate the situation again.
Dozens of incidents of misfire and loss of power upon acceleration sometimes resulting in severe shaking and flashing of engine light. Has nearly caused accident on 2 occasions where I was unable to maneuver through traffic. In shop 3 times, first 2 times technicians supposedly could not replicate problem (very easy to replicate if trying to do it). Most recently advised that I might need a "tune-up" and oil change. 2 different service centers refuse to acknowledge a known problem despite a flood of postings on internet forums describing the exact same issue.
The contact owns a 2011 Ford F-150. The contact stated while driving various speeds there was a reduction in the engine power with an illumination of the warning indicator. The vehicle failed to accelerate over 30 mph. The failure recurred repeatedly over time. The vehicle was taken to an authorized dealer numerous times; however, they were unable to duplicate or remedy the failure. The manufacturer was notified of the defect. The approximate failure mileage was 29,000.
Truck frequently goes into limp mode/stalls. This has happened at various speeds, times, terrain, etc all over the country both with and without our camper attached and both with and without tow-haul engaged. I've taken it to the dealer numerous times and each time they've updated the software according to some tsb that's been released. I've had the deflector put on, cam changed, and now they're replacing the throttle body.
Attempted to pass a car. Speed at time of attempt was 55mph. Time 2:20 P.M. and partly cloudy. Two lane road but had plenty of time to pass or an accident could have occurred. Pushed down on accelerator and the engine actually decreased speed/significant deceleration. I let up on gas pedal, maintained speed then was gradually able to pass. Think the turbo had stalled. This had happened once before, shortly after I purchased the truck. At that time I was merging onto interstate and it stalled out, for a shorter duration. After the July 31 incident, I took the truck to Ford to inquire about the issues some owners have had on the eco boast engine, which I have. No codes appeared so I was told they couldn't do anything. Then talked to regional customer service and got the same story. I am very concerned as I use the truck to tow a 26' trailer. When the eco boast turbo works, I have plenty of power to merge or pass. The above experience was scary and I did not have the trailer behind me at the time. Now I feel I can not reasonably depend on it to work as it should. I think it is the turbo but it could be the electronic gas pedal, or the transmission but I really do not think these are the issue. Please help! thank you.
While accelerating to 75mph or so, up slight hill from 65-70 mph went to pass a vehicle then truck lost vast majority of power even with all the way down and began to violently shake. Could have easily cause accident since wasn't abble to accelerate as planned to match speed of other lane. Check engine light came on. Truck continued to shake violently off and on for next mile before stopping. Problem is still ongoing under any moderate acceleration that goes over ~2000 RPM
On several occasions and more frequently as of lately, I am losing acceleration capability when I am trying to accelerate at any speed. When I try to accelerate from a stop or uphill, I feel like the engine won't go or is bogging down. To try and compensate, I try to accelerate more which only seems to make the problem worse. I have already taken it to the Ford dealer and they replaced a part on the transmission, but the problem still persists and is only get more frequent.
Was on the interstate just West of St. Louis, driving at 70 mph. Was a damp rainy day. Pulled in to the passing lane to pass a semi and truck lost power, went into "limp mode" with check engine light on. I pulled back into my lane and then off to the shoulder. Turned the truck off and sat for 5 - 10 minutes. When I powered it back up, the check engine light was off. I was able to pull back onto the highway and had full power for the rest of my trip. This is the third time this problem has occurred with this truck. Both other incidents were in damp or rainy weather at highway speeds when passing or merging onto highway.
Had a car pull into my lane, tried to accelerate to move over with out causing a dangerousness situation of a car coming up in the lane I needed to be in to avoid the idiot moving into my lane but car lost power. Thankfully the car in the next lane over saw the issues with the car moving over into me and gave me room, I'm sure they didn't expect my car to slowdown due to the loss of power. This car has the ecoboost engine 3.7 liter
I was driving to Florida in my 2011 F150 ecoboost and on the highway at about 65 mph my truck started stalling and lost power miss firing and would not go over 10 mph causing me to pull over on the shoulder. I then turned the truck off and back on 10 mins later and it began to run fine agian. I took it to Ford and they say no engine codes went off so they did not know why it would do that.
On August 11 2013, after about 2hrs of driving my 2011 Ford F150 with the ecoboost engine at a constant 72 mph I was coming out of a toll booth when the truck started to shudder and lose power this happened for about a minute, the truck regained power and continued.coming home on August 18th, again after alittle over 2 hours of driving, I went to pass slower traffic when the heavy shake, stutter and power loss happen.traffic behind almost ran me over.the stuttering/loss of power continued for about 3mins, in which I could not get to the side of the road and almost got my wife and I rear ended.Ford Motor Company has had many tsb for a possible fix on the 3.5L ecoboost engine but they have not worked.please help us before someone get killed.
Issue started again on 10 Aug. 2013. When under mild to heavy acceleration (such as merging onto interstates) the engine develops a significant miss and shudder. Vehicle was repaired once on 20 Mar. 2013 under tsb # 13-3-3. weather does not appear to be a factor. The "miss" was so severe with a K&N air charger high-flow intake kit installed that I had to reinstall the stock system. This was a none issue eventually because the Ford dealership would not place the vehicle on diagnostics until I had reinstalled the stock kit.
On I-20 East headed to augusta, ga from Alabama I pulled into the left lane to pass and the engine starts sputtering, skipping and lost almost all power. It happened 3 times yesterday. It was in a light rain and since there was light traffic I was able to slow down and get the engine to recover each time. This could be a real danger in heavy traffic. I tested it again this morning (08/18) and if you try to accelerate quickly it just about shuts down until you let off.
