2015 FORD F-150 Complaints

Driving on a freeway at 70mph all the sudden engine reved up and warning lite with wrench ?? to see owners manual came on, transmission down shifted and truck felt like it has loss of power. While driving reduced acceleration removed foot of gass pedal, truck slowed down to 40mph warning lite disappear and was driving normally. Few months later the same warning lite came on and downshift happened again at 35mph, good thing it was not on busy street.

Odometer Fraud. The contact's husband purchased a 2015 Ford F-150. The contact stated that while researching the VIN online a day later, the contact discovered that there was a mileage discrepancy. The contact discovered that an auction had previously sold the vehicle to the seller. The vehicle was a private sale. The contact contacted the auction, and it was confirmed that the vehicle was sold to the private seller at 480,000, but at the time of purchase, the mileage was 114,000. The contact made several attempts to contact the private seller, but the private seller ended the communications.

My pickup is a 2015 F-150 4WD Supercrew (5.0/6 speed auto). I was driving on an Interstate and pulling a loaded flatbed trailer. The transmission was in the “towing” mode. While leaving a rest area my truck would not shift up from first gear. I turned the truck off and re-started it and it seemed to work for a short time, but as soon as I got back to speed on the Interstate the pickup SUDDENLY shifted into a lower gear. There was no warning at all. This made the truck's engine momentarily overspeed and I felt like I was going to crash because it went from high speed to low in a very short distance. Fortunately, I was wearing a seatbelt, there was light traffic, and the roadway was slightly wet from rain. After this incident I was able to slowly "limp" it off the Interstate. It was taken to an independent transmission shop that said this was caused by a "lead frame" failure and that it was a known issue but Ford would only warranty it if it was a 2014 or older. They told me that the “speed sensor” is part of that component. They were able to repair it for me by replacing the "lead frame" - it did not appear to damage the engine or other parts of the transmission and the truck seems fine now. I do have a post warranty service contract, service contract agent said they do not specifically cover "shift plates" in their policy and it cost me over a thousand dollars out of my own pocket.

Transmission downshifting at highway speed, started to stall, went to limp mode had to manual shift to get to exit

Shutter from the torque converter and sudden down shifting. There was no accident but the problem exceeded to point where I had to get my transmission rebuild, it cost me about 3,700 to rebuild it.

While operating on my daily commute at approximately 40-50 mph, the vehicle suddenly downshifted from 5th gear to 3rd, with no throttle input change. Following a commanded full stop of the vehicle, upon accelerating, the vehicle seemed to be slipping into each gear. A short duration later, the vehicle prompted me with an orange wrench symbol on the instrument panel and the phrase "see manual." The vehicle would then only shift down as low as 3rd gear and appeared to be in a limp mode with no 1st or 2nd gear until shut off and restarted. I then took it to my local Ford dealer and had it diagnosed as a "P0722, pinpoint OSS sensor failure." It was repaired with a new lead frame on December 10th, 2025.

1.What component or system failed or malfunctioned, and is it available for inspection upon request? I really thought that it was me, the one that caused this problem by gently pressing the gas pedal when the transmission was downshifting and approaching a traffic light is when this condition always occurred and the transmission was kicking or having dificulties of downshifting. 2.How was your safety or the safety of others put at risk? NO 3.Has the problem been reproduced or confirmed by a dealer or independent service center? NO 4.Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? NO 5.Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NO My truck have less than 40,000 miles.

Sudden downshift and locking in lower gear, not shifting especially in tow haul mode but somtimes just driving in standard mode.

Hard down shift while driving locking up rear wheels almost cause an accident has happen 3 times now no trouble code can’t figure out what causing engine to down shift extremely hard have not driven truck long distances because of incidents lucky all three times it has happend no one was behind me the most recent time on 1/3/26. I ended up in the ditch with no damages to truck

Our truck, on occasions, downshifts for no apparent reason. I haven't taken it anywhere yet to have it looked at, but it is an abnormal problem. I have purchased several F150's, but this has been the only one that does it. Ford need to address this problem.
