On several different occasions after starting my Ford F-150 ecoboost I experienced difficulty stopping the vehicle when approaching an intersection. My spouse complained that the vehicle "took off" after she put the truck in reverse in the driveway. I complained about this issue to the dealer on 3/16/15 saying that I was unable to stop at a stop sign. I told them it felt like I was being pushed into the intersection. My initial feeling was that the engine was overpowering the brakes. The turbo can be heard spinning up after a cold start. I am unsure if it is really brake or engine/transmission related....updated 09/15/15 updated 10/31/2017

The truck loses acceleration when shifting to a passing gear. The check engine light comes on, and you have no power. This has happened four times. The Ford dealership has changed out the fuel injectors each time. It is currently in the shop and they have not been able to fix it yet.

At my house, the driveway is sloped. I had just parked the truck, turned the engine off, but left key in accessory position. My two daughters were in back seat (3 and 8 years old) watching a movie. I walked into my garage to drop off coffee, went back to the truck to retrieve pastries and then walked them into garage. I was out of the truck for 3-4 minutes. I went back to truck and took my three year old out of her car seat. She sits in rear seat, passenger side. I had her in my arms when I opened passenger side front door, reached across to remove keys. When I removed the keys from the ignition the truck began rolling down the driveway. My 8 year old was 1/2 out of the truck when it began to roll. I quickly put my 3 year old down and grabbed the 8 year old out of the truck. The truck was making a metal clicking sound the entire time it was rolling. Truck rolled down the driveway, across the street and into the neighbors yard. Their tree stopped the truck from rolling further into the yard and their house. The truck was still in park when I went inside to start it back up to move it back into the driveway. I drove it the Ford dealer about an hour later. Ford dealer and fomoco were involved for several months. Eventually a 'specialist' was flown in to look at truck. In the end, they claim there are no mechanical defaults and therefore, they are not responsible. They are unable to answer any questions as to how the truck did not move for the 3-4 minutes it was on the driveway when I was back and forth to the garage. They also have no explanation for how the truck rolled even though it was still in park when this happened. End results is Ford claims they never repaired or modified my truck. I have no way to prove they did or did not repair anything during the periods of time they had my truck in their possession.

I was traveling 45 mph on dry roads/good visibility/good weather in 6th gear when without warning the transmission shifted from 6th gear and finally ended in 1st gear - during this time the engine rpms exceeded 6000 rpms - I immediately shifted into neutral in order to reduce the engine RPM. Needless to say controlling the vehicle when this occurred was a major safety concern. I then shifted from neutral to drive and all was well. Last Sunday after church the transmission would at first not shift from 1st and then went to 5th gear and remained in 5th gear till I put the transmission in neutral and then back into drive. This event has occurred 4 times this far.always when the engine and transmission are cold!!!

Without warning the transmission began downshifting and upshifting by itself. Vehicle went from 5th gear to third, back to fifth and down to first. Vehicle skidded as a result. Brought people to dealer. They explained that there was not a recall currently, but that there was a service notice and that this had happened other vehicles.

Follow up to complaint listed below (beginning with summary): It should be noted that this incident did not occur in humid or rainy conditions. This incident did not occur while traveling at highway speed or wide open throttle. This incident occurred while starting from a complete stop under light acceleration turning left across traffic. Vehicle lost all power and would not move. Pushing the gas pedal did increase engine RPM but vehicle would not move. The behavior exhibited by the vehicle sounds very similar to the condensation problem I have been made aware of with the 3.5 V6 ecoboost. However none of the circumstances Ford claims causes the issue existed. This is an extremely dangerous condition. Weather was approximately 15 degrees and sunny. I have experienced the problem when the vehicle has been cold and after it has been running for a while. Summary: While attempting to cross oncoming traffic lanes to access interstate vehicle began to move then suddenly lost all power. RPM's went up to 4000 RPM but vehicle would not move. Vehicles were approaching in excess of 50mph. I managed to barely avoid being struck by oncoming traffic and pulled to side of ramp. Vehicle then began to move again. Took vehicle in for service. Dealership performed two fixes involving some form of air dam. On 02/24 vehicle did the same thing luckily in a parking lot this time. This is an extremely dangerous condition which leaves no error codes so far. I am seeing many similar complain ts online. Taking vehicle in for service again on 3/3/15 as the issue occurred again today 3/2/15.

Going up hill, stepped on gas, transmission shifted down one gear, let off gas and engine died. It showed low oil pressure on dash. Steering was hard (had to pull to side of road). Vehicle was then towed. Oil dip stick was pulled out and will not go back in. Latter discovered engine is seized up for no know reason.

Generally speaking with a new vehicle I "baby" a new vehicle until I get over 75,000 mi. First incident - noticed around 40,000 mi. When accelerating to pass at highway speeds the vehicle shudders and doesn't have power. Thought it was bad gas, turbo lag, or intermittent transmission issue. Problem occurred a few times over the years, every time was during acceleration to pass or merge on to expressway conditions. Keep in mind since I was in the babying mileage range I rarely performed such acceleration. But after a couple of occurrences, I discussed this with a friend that also owns an ecoboost and he thought the same reasons. I have 7 year 100,000 extended warranty so I thought I would wait until the problem occurred frequently enough to easily trouble shoot. Of course frequency wouldn't be enough until after I get out of the "baby" stage on mileage. Currently the vehicle has over 75,000 miles. I no longer baby it. Problem occurs every time I accelerate to pass at highway speeds. Also, I have had the problem when accelerating to enter highway traffic from ramp. The ramp occurrence appears to be when I'm at a speed and then accelerate. Not sure if the problem happens when accelerating from a stop or slow speed. I'm concerned this may lead to an accident and potential a life threatening or changing event. What is one life worth? I guess that depends on if its yours. I believe this is a life threatening event and know that drivers like myself once aware pay attention and proceed with caution and this is the reason there hasn't been life lost, or no one has proven this was the root cause to accidents that have occurred. I fear for those who are not aware of this issue and that they may discover it at the wrong time. Please do something to help.

2011 F-150 XLT will not go into reverse or other times when you put it in reverse the vehicle behaves like it's in neutral then will suddenly shoot backwards (does this in drive as well-forward). When this occurs the backup lamps do not illuminate and the backup camera does not function and the instrument panel does not display the what status the vehicle is in...ie drive/reverse etc.... I took the vehicle to my mechanic who immediately informed me the vehicle was under recall (NHTSA campaign #12V190000). He printed the service bulletin and recall info. I took the vehicle to Ford where I was told my VIN # did not fall under the recall despite the fact it's the same exact model transmission, vehicle, and issue to the letter. It should be known that many more vehicles are affected beyond the initial recall. This has the potential to be an extremely dangerous defect as the vehicle lunges backwards/forwards without any indication of the status of the vehicle and while the vehicle's safety features are not working properly.

My 2011 F150 4X4 rear end limited slip differential appears to be locked up. At about 20,000 miles my gas mileage dropped from 18.4 to 17.1 and a whining noise is now present from the rear differential. Also you can hear the rear tires skip during slow turns at corners or in parking lots.

Rain, misty, wet conditions. 2011 Ford F150 ecoboost. Went to pass on two lane straight, flat highway. Accelerated in to left lane. Upon rapid acceleration vehicle immediately decelerated and lost power. Let off of gas pedal and tried to accelerate again. After pause vehicle came up to speed and I was able to pass safely. If someone was right behind me, trying to pass slower vehicles as well, they could have possiblyrun in to me. Ford has placed it's ecoboost owners in an unsafe condition.

While towing my camper at 60 mph up an incline my 5.0L F150 began to lose power, as I increased pressure on the accelerator the power to the vehicle decreased even more. The service engine light came on and I limped up the hill at a whopping 20mph on the interstate. Once on the downgrade the vehicle came back up to speed and the service engine light went off. The truck continued to have power issues and a knocking from the motor when I was climbing hills. I took the vehicle to the Ford garage and they told me there were no codes to tell them what was wrong. The vehicle still has the apparent miss and knocking sound at certain RPM's and now has an issue starting for the first time of the day. I again took it to the Ford garage when the starting issue was happening and they told me again that the vehicle still had no codes to explain this problem. I tried all of the easy fixes but the vehicle still has the same starting and power loss issues and Ford can not tell me what is going on with my vehicle. My best guess is a catalytic converter issue, but I can do nothing about it until I know for sure.
