Two times when on an expressway at highway speeds during a rain storm I have had my engine lose power and the check engine light came on. Both times after slowing down the engine regain power and I could continue my journey. I have the 3.5 turbo engine and noticed online that this complaint has been mentioned by others. I did bring up my concerns to my Ford dealer and they claim to have no knowledge of any similar complaint with this engine. Any information or help I can receive from you would be greatly appreciated.

This has truck has a shudder or vibration from starting out from 1 to 10 miles an hour and additionally when passing and driving on the highway. There is also an acceleration delay at all speeds. This truck is equipped with the 3.5L eco boost engine. These issues are especially more noticeable when there is a load on the truck such as a topper and luggage, etc.

As I was passing a truck the engine cut out, lost power the tach dropped from 4000 RPM to below 1000 and the engine shuddered violently. This has happened before and the dealer keeps telling me everything is working correctly. This time I took video of the instruments to prove it. The engine check light flashed all the time this was happening and then went out when the engine began operating properly.this starts after you try to pass a vehicle and it puts you in a dangerous position of being in the passing area and have no power to get by, this could lead to a major problem. I am a certified accident investigator and have been a police officer for 45 years. I am also a master mechanic, this has to be corrected by Ford soon.

As I accelerate, the truck seems to going into neutral for about three seconds. Then it reengages and jerks violently. I have taken the truck to the dealership twice. The first time, they reprogrammed it but didn't repair the issue. This last time, the technician told me to pick up M truck because they couldn't recreate the issue I was experiencing. Another technician stated it was the eco-boost but that Ford was side stepping the issue because they couldn't find how to fix it. This is a safety issue because last time this occurred, I was changing lanes on interstate 10 and almost caused an accident.

3.5 eco boost engine has a dead spot in it. Mash on the gas pedal and doesn't do anything, then sprints off. It has done this several times. Also there is a small roar at times coming from left side of engine when accelerating. The sprinting will occur other times when accelerating. Haven't taken it back to dealer but I'm going to.

2014 F150 ecoboost in service for 9 months. After driving 4-5 hrs in moderate rain, 35-40 degrees, during acceleration to enter interstate, engine stumbled badly with flashing check engine light. I was concerned of being rear-ended by traffic behind me. After a mile or two the flashing check engine light went out. The truck responded normally for about two hundred miles after this incident. Am on a trip and 1500 miles from home so have not yet taken the truck a dealer. This report is during mid-trip.

Once more this truck has lunged without notice!! with the truck in my garage I pushed the button (inside the truck) to open the garage door, started the truck and as soon as I put in in reverse it lunged backwards just catching/hitting the bottom of the garage door as it was going up, some scuffs on the trucks tailgate trim and it bent the lower garage door panel and knocked it off the track. Ford has done squat to fix this issue along with other major issues this truck has from day one!! NHTSA please look into these issues!!

2014 F150 ecoboost V6 - engine shudders and stalls upon rapid acceleration; issue has been addressed with "deflector shield" but this shield is already in place in my vehicle but the vehicle continues to have this issue - I feel the vehicle is unsafe but Ford offers no assistance with resolution of the issue.

Was traveling behind two vehicle doing approximately 50 mph in a 75. Went to pass and pressed the accelerator, and nothing happened. The vehicle starting shuddering, and stalled as I pulled along side the first vehicle. I let off the accelerator and attempted it again, still nothing. With loss of power, I had to move towards the shoulder since over taking the vehicle was impossible. The lasted for approximately 10 seconds, during which the check engine was flashing. Approximately 2 months prior, it happened while driving to dallas, but not to this extent. Weather condition for both incident was heavy rain, and I had been driving in rain for several hours. Engine code showed P0306 for cyl 6 misfire.

New truck 2 weeks old went to pass another car and the engine cut out and almost stalled out.

- Old Orchard Beach, ME, USA

While going up a steep incline, I went off of the gas to slow down as I was approaching a corner. When I got to the corner, I attempted to turn and realized I didn't have any power steering. When I looked at the gauges, low oil pressure was displayed on the dashboard and the engine was no longer running. The truck did restart and I was able to drive away. Ford is stating that since there weren't any codes, there is nothing they could do. This is a very dangerous situation and could potentially cause an accident.
