Transmission down shifts while accelerating, slips when starting from a dead stop, and shifts extremely hard when shifting. It is a safety risk especially when pulling out at an intersection, as it stops (or will slip) in the middle of the intersection.

There were no early indications or warning signs prior to it starting yesterday (08/06/2025).

While driving at 60 mph my vehicle went from the 6th gear down to 1st gear on its own bringing the truck speed down very quickly the vehicle behind me almost hit me in the rear I pulled over speedometer stopped working and a imagine of a wrench was on the dashboard I cleared the wrench 🔧 image on the dashboard and tried to restart the truck turned the key and nothing happened tried again and truck started pulled out and started driving home 4 miles away and it happened again when I got home I googled it and found it is a known problem with the transmission in the 2015 ford f150 where the sensors in the transmission fail to read your speed and then reacts as if the vehicle is stopped so it then puts the transmission into 1st gear where it would be when you are stopped which creates a very dangerous situation especially if you are on a crowded road at higher speeds

First time this incident happened (around April 2025) while driving on the highway. Going about 70 mph and the truck dropped down into second or first gear almost causing an accident. Had to pull over on the side of the road. Check engine light was on the dash. Turned off the truck And let it sit a little bit and restarted it and it seemed to be OK. This most recent incident happened on Saturday, July 5th 2025 , truck kept dropping down into first gear and then just would not go anywhere. Had it towed to Auto clinic and they diagnosed the truck with not recognizing the gear selection position. They stated that this truck should have fell under the recall status for 2015-2017 f150’s as it is doing the exact same thing that they have seen many trucks get fixed for because of the recall. The Auto clinic recommended I file a safety report and also contact Ford.

The engine while operating at normal speed loses power to a rough idle and is remedied by putting the vehicle in park and restarting the engine. The engine never fails to start after restarting, but could fail at any moment, short or long term.

Problem: Engine unexpectedly goes to idle speed after accelerating up to highway speeds. Cruise control was not engaged at time of failure. This has happened three times, all after a cold start up, and all within 2 miles of home. The most recent occurrence being 6-19-25. At time of failure, multiple warning screens come up on the dash, including "Hill Start Assist Not Available", "Service Advance Trac", "See Manual" (with a picture of a wrench). No check engine light comes on, and no error codes are set. Engine does not respond to accelerator pedal, engine will only idle roughly. When this occurs, the only remedy is to pull over to the side of the road, shut off the engine, then restart the vehicle. Each time this has happened, the engine starts and runs normally with all warning messages cleared from dash. Safety Concern: Unexpected loss of power can increase the likelihood of an accident, especially in heavy traffic. This truck is used frequently for towing, and an unexpected loss of power can create a loss of trailer control.

They kept the truck for approximately two weeks, driving it daily without having the issue reoccur. They performed diagnostics on electronic modules but found no concrete issue.

Transmission constantly shifts erratically. When this happens, the transmission gets stuck between 3rd and 5th gears and sometimes only stays in 5th gear, no matter how fast the truck is going or even if it is not moving. About half the time when this happens it causes a rough "jerk" and could cause loss of control. If you must stop at a stop sign or stop light when this happens then you're impeding traffic just trying to get back up to speed after your stop, which could lead to an accident. This also causes the check engine light to come on.

Today, [XXX] while driving at highway speed this vehicle experienced a unrequested transmission downshift, from 6th to 3rd, causing unexpected rapid vehicle deceleration.

I did not hear any audible or see any visual warnings that this incident was about to happen. This vehicle will be taken to Starling Ford located at 3000 Cheney Hwy, Titusville, Fl 32780 on June 16, 2025.

Transmission is downshifting at high speeds unexpectedly and without apparent cause. Ford has issued a recall already for the same year and model for the same issue, but my VIN is not associated with the recall.

This vehicle was purchased by a friend with the factory tow package. No modifications were made before my purchase three years ago. I installed a factory brake controller for a travel trailer I purchased. The software was enabled with Forscan, and the dealer updated the software to the latest available. Even with a new seven way plug, the truck displays "trailer disconnected" when using the slide brake and also never shows any output when braking. The brakes do engage but very mildly. The travel trailer brakes normally on my other vehicle. There are no fault codes and no obvious connection issues. The dealership today said they do no know the cause and would likely be unable to resolve it.

At highway speeds, under moderate acceleration, the vehicle downshifts unexpectedly. It causes sudden loss of torque. Has happened when trying to overtake and caused sudden vehicle deceleration in the passing lane, which is dangerous.

On or around May 28, 2024. My husband and, I were going to a recital. He was already in the truck.I told him. Pick me up at the mailbox.( I had mail to go in box).I started walking down the driveway(paved). The next thing, I was on the cement screaming. I had been hit, with the truck. My husband ran to help. He said, he didn’t see me. And, the beepers ( sensors)didn’t go off.Rescue was called, checked me out. Did not transport. But, I went to hospital later. Bruises and a broken right arm. Several weeks went by. I really didn’t believe the sensors,didn’t work.We were in a parking spot. But, the truck in reverse. Waited for people to go by. Sometimes it worked, sometimes it didn’t. We did see people on the camera. Recently, I was behind the truck again. The sensors did not go off! We are very cautious now. Aware of the problem. Why hasn’t this truck been in the recall lists?. The accident was visible on our ring. I have video. But could not figure out to download. I can sent by email.

The transmission jumps gears at any speed, I was researching the topic and saw the NHTSA is probing some F150s for a similar problem. And I was wondering if my vehicle was in the affected line of production.

An unrequested transmission downshift that allegedly causes the vehicle to decelerate rapidly.

Truck down shifts hard while driving. Hill assist warning light comes on and truck goes into limp mode and looses power going 60 mph. Pull over truck runs very rough. Turn truck off and back on screen says hill assist not available. Press ok and truck runs normal again. Happens every few days. Definitely could be dangerous if it happens on a bigger highway. Has happened 5 times over last few weeks at different speeds.

Upper rail for sliding rear window came off causing the rear slider to fall into the back seat. This is a known problem with 2015 and newer F150's with a rear sliding windows. Ford refuses to acknowledge the issue and take responsibility for it. It is a failure of the adhesive that holds the top rail for the slider to the window.

Driving home today, my truck just started downshifting without warning. My truck was almost rear ended. I had about 5 min until I got home. It would take off and drive fine for a moment, and then out of nowhere drop all the way down to first gear. Very dangerous!

Shortly after I bought the vehicle in 2015, the transmission would frequently make a loud metal on metal sound when accelerating as the transmission downshifted from 5 gear to 3rd. I took it to the dealer several times. They said it was a manufacturers fault from a bad batch of transmissions and not something the dealer could permanently fix or was responsible for. No other indications. I am concerned the transmission could lock up and cause an accident. Date of the incidents is from November 2015 to present.
