2014 Ford F-150 power train problems

“The contact owns a 2014 Ford F-150. The contact stated while driving at an undisclosed speed, the transmission unexpectedly downshifted without warning. The contact called a dealer and was informed that the vehicle was covered under NHTSA Campaign Number: 24V444000 (Power Train). The dealer sent a technician to the contact's workplace for the recall repair, and the technician performed the powertrain control module software update; however, the failure recurred approximately a week later, and the failure persisted. The contact stated that the instrument panel occasionally went blank during the failure, requiring the contact to restart the vehicle for the vehicle to operate as intended. An unknown dealer was notified of the failure and the contact was provided an estimate for a diagnostic test. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 160,000.”

“I was driving about 75mph when my 2014 Ford F150 suddenly downshifted from 6th gear to 2nd. As a result of the unexpected downshift, my body was pushed into the steering wheel, and the rear end of the truck slid sideways as it slowed down to 65mph. The truck had a loss of power and I couldn’t accelerate. When I pulled over on the side of the highway, I used my code reader to read the codes that came up. The codes that came up pointed to Powertrain Control Module. When I looked at the PCM, it said P0720, Output Speed Sensor. I looked up the issue online and found that there is an open recall on the 2014 Ford F150 with the 6R80 transmission, and the recall is the issue I stated above. I went to two different Ford dealerships and they said that my vin isn’t listed under the recall so they won’t fix it. This is the manufacturers issue and they won’t fix it. The truck is unsafe to drive now.”

“The contact owns a 2014 Ford F-150. The contact stated while driving at an undisclosed speed, the transmission unexpectedly downshifted. In addition, the contact stated that the vehicle was sliding. No warning lights were illuminated. The vehicle was taken to the dealer several times; however, the contact was informed that the failure was due to transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The contact stated that the failure was not present until after the recall. The contact had received notification of NHTSA Campaign Number: 24V444000 (Power Train); and the recall repair was performed in February 2025. The contact stated that the failure was not present until after the recall repair was performed. The manufacturer was made aware of the failure and a case was filed three times. The contact was advised to take the vehicle to another dealer for a second opinion. The failure mileage was approximately 116,500.”

“My 2014 F150 XLT experienced recall S4S37. I brought the truck in for the recall after experience a sudden downshift into 1st gear while driving at 70mph. The PCM software update was installed during my first visit to my local Ford Dealership (Team Fod in Steubenville, OH). The issue occurred once more after the PCM update and team ford dismissed me after they could not replicate the issue. The sudden downshift happened twice more and I was again dismissed as team ford could not replicate the issue. After the downshift had occurred 4-6x, team ford reached out to Ford Support AT MY REQUEST to resolve the issue. They informed me I should consider replacing the lead frame. With the ongoing recall issues of the 2011-2013 F150s (which included a lead frame replacement as part of the recall), this should have been recommended at my first appointment. The sudden downshift continued over the course of 6-8months prior to team ford recommending I replace the lead frame which then led to my transmission blowing. 1. The lead frame should be included as part of recall S4S37. 2. My transmission should be covered by Ford as the ongoing sudden downshift while Team Ford failed…”

“Me and my wife was going 45 mph down the road and it downshift to 1s 2nd gear out the blue almost causing a driver to almost rear end us scared us to death so we pulled over when we could, no lights on dash nothing once we stopped it will be good for awhile then happen again. The dealer said he took it to the Ford dealership he couldn't have cause it's still do say he couldn't recreate what is was doing, but the dealer drove it and it did it to him.”
