Loss of power and shudder at speeds of 60+mph when trying to accelerate to pass other vehicles or going up hills. In 2014 I purchased a used 2013 Ford F-150 eco boost truck. About a month ago I experienced a shudder and loss of power when trying to pass another vehicle while driving on the freeway. The mph was about 70+ miles. Since that time it happens all of the time when driving above 60mph or higher when I try to accelerate. If I gradually accelerate it doesn't happen.

My truck has been experiencing hesitation upon acelleration and is making noises and my check engine light was on. I took it to the dealership on February 2, 2016 be fixed and at first it was covered under warranty. I took it back on February 16, 2016 bc I had to have a Ford rental per Ford. The truck was repaired but then it wasn't covered per Ford and I had to pay over $400 to get it fixed. My check engine light came on again and it had to go back to the dealership but this time it was covered under warranty. I just got my truck back on April 11,2016 and today on April 14, 2016 the light is back on. I am waiting on a call back from the Ford dealership to find out what to do next.

September 2015 I-75 North bound, attempted to pass a vehicle at 70 mph and had loss of power, check engine light and violent engine shaking for 5-10 minutes on the highway before shaking and check engine light stopped. Happened in the gainesville fl area cloudy but dry day, had all scheduled maintenance done in venice fl prior to getting on the road at the dealership, 36,500 miles. October 2015 I-44 East bound tulsa ok, reentering the interstate had loss of power unable to enter at appropriate speeds, check engine light and violent shaking. Slammed on gas and then brake pedals with no difference. Pulled off the interstate parked the truck, turned off and restarted as soon as it started gunned the gas pedal RPM in the red line and again the truck lost all power, check engine light and shook did this for 30 minutes until I was able to start the truck and gun the RPM into the red line without loss of power. Called dealership asking about hydroplaning and engine losing power like in the Tundra trucks, was told no Ford does not have that safety feature. Cold and wet weather conditions 40,000 miles. November 2015 on tx 82 West bound at 80 mph, 35 degrees and rainy conditions. Attempted to pass a semi and had loss of power, check engine light and violent shaking was a passenger in the truck at this time and was still able to feel the shaking from the engine. Again lasted 5-10 minutes. Went to the dealership for oil change before the trip in the beginning of November. 43,000 miles. Have been to my dealership asking about this problem, and have been told there may be a recall but so far nothing. I do interstate driving in less than ideal conditions (rain, snow and ice) I need this truck to preform that is why I bought it. I understand it takes time and money to make a recall happen, but make no mistake this is going to cause accidents.

3.5 L ecobost losses power while driving on highway and poor acceleration from stop light or when accelerator pedal is depressed when passing. Several close calls from vehicles going faster approaching from rear at stop lights and while passing. Had close encounter with two tractor trailers on hwy while traveling at 60-65mph going up a hill. Went to pass the trailer truck that was slowing down. After entering the passing lane and pressing the acceleration pedal the truck had a quick shake then with the acceleration pedal pressed to the floor the truck slowed to 45 mph and would not accelerate. I was almost rear ended buy another large truck attempting to pass the slower one. Sometimes has ticking noise at start up that seems to go away after running for 5-30seconds. Has P0016 code and P0299 codes.

My truck has over 115,000 miles on it now I drive 50,000+ miles a year. I bought the vehicle new 1st occurrence was at appx 50,000 miles I was attempting to pass on interstate the engine stalled started run rough and lost power this corrected it self after I let off the throttle in a few seconds. It did this one more time a few days later. Talked to local dealer asked about fuel filter, they said there was no filter. They recommended running fuel injector cleaner. I did this and continued to do this but engine idled rough at stop signs even in park. It finally did the same thing a third time and then again from a stop sign. I had spark plugs replaced this was at 95,000 miles this helped I did not have the stumble problem again but still idles rough. Finally 2 days ago it was going down road and wrench light came on and vehicle went into limp mode pulled over shut off and restart engine it went into normal mode no problem. I have cleaned the map sensors all three but no help. I did note map sensors are wet. I rear in one of your many complaints about this problem that it may be condensation from inter-cooler this sounds plausible. When it goes into limp it does not throw a code so no way to know what is wrong. I have spoke to my dealer no help. I have not called Ford yet. I have rear multiple (100S) of similar complaints a lot of them on your site. Will it take someone dying for you to force Ford to fix this. The truck cost over 50,000 I am still paying for it and it is unsafe. I had a Nissan with over 300,000 miles and no problems do we need to buy foreign made vehicles to get a good product" will american companies not stand behind their products" I as a tax payer bailed out Ford and GM can I not expect a quality made product in return! I guess after someone dies in a crash caused by the F150 stalling on the highway the NHTSA will finally step in an force a recall!!!

The engine splash shield has come loose three times in about a year. This is very large component under the engine. The dealership indicated there are a lot of F-150's with this issue, that snow will pull the shield down. They also asked who changed the oil - I believe the shield needs to be removed to change the oil. The dealership indicated the problem is not covered by Ford or the warranty. If the shield comes loose it creates a clear hazard for cars behind the truck. The shield has come loose after an oil change (by the dealership), in the snow, and one other time.

Basically the truck will not start. It has plenty of power and doesn't seem to be electrical. When starting the truck I hear the starter running for ~5 seconds but the engine never fires off. On my 4th or 5th repair after having it towed back to the dealership. Each time they try replacing the fuel pump only for it to work briefly. Twice it started for them at the dealership after it had been towed. Either they don't know what the problem is or the work they do fuel pump temporarily fixes the real issue. This cycle has repeated for 4-5 times for a vehicle with less than 30K miles. First instance was in February 2013. Last 3 instances have been in the last 3 months. I have never seen a problem while driving but if its a fuel pump issue as they keep claiming then the issue could arise at any time. At this point I don't trust nor feel safe driving this vehicle. Oh I should mention that this last tow truck driver towed 9 other Ford-F150 this week that had the same symptoms.

This is an update to my complaint filed preciously. After the second episode of loss of power and the check engine light coming on. I took my ecoboost powered truck to a Ford dealer and they performed tsb 14-0017. This was supposed to fix the engine loosing power. This is why the NHTSA closed the investigation of the F150 ecoboost. This has not worked. Yesterday 11-7-2015 I was on a 2 hour highway trip in rainy conditions. While driving the motor again lost power and could not even maintain highway speeds. This was dangerous to my family and everyone around us. The tsb from Ford has not fixed the dangers of these trucks. Please re-open the investigation into this dangerous vehicle before someone is killed or injured. American roads deserve safe cars.

We have taken this vehicle numerous times to fix the transmission and motor (eco boost 6-cylinder) the transmission does not shift smoothly, the vehicle lurches and has a lack of power/acceleration. The vehicle is in motion and experiences these problems both in city and highway driving. The NHTSA has hundreds of complaint and Ford has received over 4000. The last time we took it to the dealer their explanation was: "cannot duplicate customer's complaint" this platform is faulty and somehow Ford has been able to keep it off the radar. Apparently Ford does not know how to fix it and continues to deny that there is a problem.

- Bartonville, TX, USA

Reproduceable loss of power after extended highway driving in humid weather. Loss of power happens when the ecoboost intercooler (cac) builds up condensation and then throttle is applied to pass or merge into traffic. When trottle is applied the condesation water is pushed by the turbos psi into the motor. This causes a missfire and the engine to loose power unexpectedly. This has happebed when attempting to pass a slow moving vehicle on a country road with oncomming traffic nearly causing a head on collision.

2013 Ford F-150 with the 5.0 V8 engine that has 51,000 miles. On numerous occasions the truck will crank as normal but will not start, as well as lose power while driving. Ford road side had the truck towed to summerville Ford. Ford service department advised that a fuse form the factory was too small and was overheating causing the truck not to start. The service department told me this is a known/common issue, and the fix was for them to install a fuse relocation kit by splicing into the wiring in the fuse box as well as install a larger fuse. Of course this seems like an engineering/fuse location issue and not a worn out part issue.
