The contact owns a 2014 Ford F-150. While driving, the engine power reduced and the vehicle stalled on a hill. The contact stated that the gears failed to shift properly. The vehicle was reversed down a hill and the contact was able to pull off the roadway. The vehicle was not diagnosed by a dealer.

While driving down the highway at roughly 75mph the vehicles speedometer suddenly jumped to 105mph then down to 65mph, then to roughly 90mph and finally dropping to 0mph at which time the transmission suddenly shifted down into 1st gear causing the rear wheels to lock up while going 75mph almost killing myself. After this occurred and the vehicle stopped the ignition was turned off. Once restarted everything seemed to be functioning as it should. A couple days of driving normally went by before the vehicle locked itself in 5th gear, the only way this was fixed was for the vehicle to be cycled on and off. A few more days of normal driving went by and the vehicle then exhibited shifting from 1st to 5th once speed reached about 5mph. This occurred until the vehicle was cycled on and off. From my research online this is directly related to the output shaft speed sensor in the transmission lead frame. 2012-2013 F150S were recalled due to these same symptoms, however, there has not been a recall for 2014's as of yet, even though they use the same faulty transmission lead frame.

The shifter malfunctioned sitting in my driveway, trying to shift down into a lower gear, there was resistance, then the key would not come out of the ignition

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 NHTSA website and other sites associated.

Had to repair the "lead molded frame & gasket" ! truck would jump threw gears while moving at any speed. Final draw was when truck dropped to 1st gear while traveling 70 mph on I-64 East nearly causing truck to flip over after screeching tires and running other cars off the road! Ford dealership maintenance dept. Told me there were recalls for same problem on F-150's but not for the year 2014 as mine is!.. please note if it were wet/raining at the time this happened to us, there would have been a severe accident with possible casualties...!!!

No recall, but have had trouble with the transmission from day one, it jerks does not change gears the way they should, supposedly fix they installed a new transmission pump and still the same, say they cannot duplicate the problem. When on the highway have to slow down and then when you try to accelerate it jerks try to pick up speed

Turbo went in the truck which then cause engine and transmission damage. Mechanic says the engine, transmission, and turbos need to be replaced quoting over 10K. Also, a neighbor had a 2014 F150 do the same exact thing around the same mileage and I thought that was very odd.

Vehicle entered limp mode while attempting to accelerate through an intersection of a city steeet causing sudden unintentional deceleration. Vehicle no longer able to accelerate and had to limp onto shoulder. Cel on and blue wrench on screen. The next day the same problem happened at highway speed resulting again in sudden unintentional deceleration.

- Tacoma, WA, USA

Throttle body went out after 40,000 miles. Driving down the road wrench icon pops up and a few seconds later the truck stalls and engine cuts out. Take it to Ford and that part is not covered under my extended warranty.. big surprise. Talk to customer service and there is nothing they will do either. So out 600 because Ford knowingly sells these vehicles when they know that thousands of people are having the exact same problem.

- Alamosa, CO, USA

At 40,000 miles, had to have the throttle body replaced (extended warranty, so cost not material to me). Concern is that on a 1300 mile interstate round-trip, my engine shut down 5 times. In each case I lost all acceleration without warning and had to coast to the shoulder of the interstate. My dash showed a wrench symbol, which would disappear after I had turned the ignition off, then back on (as if nothing ever happened). I subsequently learned that a defective throttle body put me into a "limp home" mode meaning I could continue driving only at idle speed. The limp home mode (I learned this term from reading a customer blog) caused immediate deceleration on the interstate at full speed 3 of the five times my engine shut down. Had I just passed another vehicle or had an inattentive driver following me, I very well could have been rear-ended. A Ford dealer, midway through my round trip, could not determine a repair code for this situation. Only after the 5th engine shut down, did a "check engine" light appear. This allowed a second Ford dealer, at the end of my trip, the documentation needed to replace the throttle body. Very dangerous situation...the first Ford dealer sent me on my way despite what now appears to be a well-known problem "internally" at Ford. The 2nd dealership miraculously had a replacement part on hand and made the necessary repair within 8 hours...I believe only because I stressed the point about unsafe travel!

2014 Ford F-150 ecoboost - at approximately 60 mph vehicle will shift into 1st causing the rear tires to lock up. Will then shift back to 5th or 6th and drive normal. Has happened several times with no warning before it happens. Also will shift from 1st to 5th when pulling out and will not accelerate. Will have to pull over and turn vehicle off, then restart. Sometimes it will lose all gauges when doing this and throw a check engine light. Check engine light will go out as soon as restarted. Again, no warning ahead of time when it does this. Seems to be the same issue that has been recalled in earlier model Ford F-150S. Have scheduled appointment with Ford dealer.

The contact owns a 2014 Ford F-150. The contact parked the vehicle in the driveway (on an incline), shifted the gear to park, and removed the keys from the ignition. The contact went inside the residence to retrieve a wheelchair for the passenger. As the contact was transferring the passenger to the wheelchair with the passenger door open, the vehicle started to roll away in reverse. As the vehicle was rolling away, the passenger in the wheelchair was dragged down the driveway and into the street. Police report number: 17-24021 was filed. The passenger was transported to the nearest hospital with scratches and scrapes. The vehicle was towed to the dealer (legacy Ford in rosenberg Texas, 833-811-8141), but the cause of the failure could not be determined. The contact was informed that there were no failures with the vehicle and had no explanation as to why the vehicle rolled backwards while in park. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 23,477. Contact states there is a recall for 150 Ford truck clip that locks gear shift cable to transmission.

While driving the vehicle and in motion when passing another vehicle the vehicle started to stutter and lose power. The engine icon started flashing. The icon went away shortly after this but this is the second time this has happened. After checking online there are several issues in regards to the 3.5 ecoboost engine doing this.

2014 F150 has been diagnosed with a lead frame malfunction by a Ford dealer. While driving on the highway at 60 mph automatic transmission shifted into 1st or 2nd gear by itself and instantly and dangerously slowed the truck to 20 or 30 mph. Had to pull over, turn truck off then restart to regain normal control. Very dangerous, almost lost control of the truck. Found out this is the exact same problem as a lead frame recall for 2012 F 150S. Why not 2014S" we could have been killed. Why has this model year not been recalled"

- Kansas City, MO, USA

The trucks overheats and ignition coils fail. This mainly happens when traveling through the mountains.this causes the truck to lose power and leaves me stranded on the highway broke down. This has been a problem ever since I purchased the truck new. Ford has been absolutely no help in solving the problem. I have documentation of over ten ignition coils failing and multiple engine over heatings.
