2015 FORD F-150 Complaints

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.

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.

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.

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.

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.

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.
