Submitting another complaint about this issue. 2014 F-150 SuperCrew 3.5L TT with 6 speed transmission. Was driving with my whole family in the car yesterday, 03/06/22. Truck started hesitating again, RPMs went crazy, MPH gauge freaked out. I shifted into neutral before the truck would go into a skid like it did the other day. Put the truck back into drive and it was fine. Turned around and took our other vehicle. This thing is a death trap. Recall the 2014 model year now. I've found several others online with 2014 model year with the same issue.

My truck would randomly hesitate during the acceleration phase. Eventually it LED to me being stranded due to the inability of the vehicle to start. Trucked was towed to the dealership and I was informed that this was a reoccurring design problem in the electrical system that ford has been aware of for quite sometime. I urge your agency to strongly consider a recall for numerous reasons. 1. It's a design flaw 2. While I wasn't an issue for me normal acceleration can be just as important as normal braking in certain situations due to safety considerations.(merging, turning left across traffic, etc.) 3. It wasn't an issue for me but my service invoice indicated a slight burn on the fuse terminal. Obviously a possible fire hazard due to poor design. Thank you for upon consideration.

2014 f150 w/~55,000 miles- (1) 7/30/19- carrying light load in bed (200 lbs+/-) & 2 people including driver, on major highway during rush hour accelerating up hill, had driven 15 minutes without issues. Vehicle suddenly lost all power and tachometer red lined. Did not notice if any warning lights on as was trying desperately not to be dead due to 18 wheeler right behind me. Just as suddenly resolved after about 10 seconds. (2) 7/6/19- truck in park with emergency brake engaged, facing uphill on boat ramp with lightweight boat trailer in tow & in "tow/haul mode". (no boat, only driver & 200-300 lbs load in bed) disengaged emergency brake & vehicle rolled backward while still in park. Braked. Put in drive & vehicle rolled backward before finally engaging & able to accellerate up ramp. (3) frequently, since truck brand new, hear a "thunk" when shifting from park to drive (on flat surface) & especially loud, every time I shift from park to reverse (also on flat surface) & always doing either if on a hill. Took to dealer when still under warrantee who says this is normal. I live in a very flat area so only discovered that transmission hesitates &/or slips on these occasions, after warrantee expired. Taking it to my trusted mechanic who employs a certified ford truck master mechanic & has no financial reason to downplay issues.

When accelerating the transmission hesitates and drops to lower gear loses power

Filed Oct 21, 2018 · Transmission · 44,167 miles · MO

I'm having two issues with the drive train of my 2014 f150. First is accelerating from a stop. Its as if the driveshaft is missing a tooth and doesn't turn with the transmission. It hesitates then catches and you hear a thud like metal hitting metal. The other issue is far more serious. While on the highway I began accelerating to change lanes. As I changed lanes and put my foot down, the truck acted like it was going to accelerate or downshift and accelerate, but then did neither. It was like the gas peddle was dead. I took my foot off the gas peddle, then re-applied and it was fine. I however was almost reended. I've seen both of these issues by several folks on the federal safety agency website and other sites associated.

While in motion at highway speed (55-70mph) and city speed (20-35mph)the vehicle lost power and/or hesitated upon acceleration several times over the course of 3 days the middle of may 2018. After diagnosis by ford dealership that timing chain on the ecoboost engine with only about 75,000 miles on it required replacement. About 5 days after timing chain replacement the hesitation returned and upon diagnosis by ford dealership it was determined the phasers were bad. Despite numerous complaints and reports of this occurring in 2011-2015 ford f 150 ecoboost models in america and canada ford refuses to admit there is a defect. While maybe not directly a safety issue I believe it is as one of the failures occurred on the interstae in heavy traffic while passing a semi truck and power was lost and evasive action had to be taken to avoid a collision due to the timing chain power failure. Can't argue with what actually happened, if that isnt a safety concern for ford or the federal safety agency I don't know what is. Defective system for 2011-2015 ford f150 ecoboosts
