2015 Ford F-150 Complaint Log

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. It has not been confirmed by the manufacturer or dealer, only by the article from USA Today. The vehicle has not been inspected by anyone, as it just started yesterday. There were no early indications or warning signs prior to it starting yesterday (08/06/2025).

My transmission down shifts while driving and locks up my rear wheels. It almost caused me to wreck on the highway today.

Having issues with lead frame. Truck is a 2015 F150 3.5 Ecoboost with the 6R80 transmission. Every so often the orange wrench appears and dash looses what gear and where it is in the column. Have taken pictures as well as pulled the codes that appear P0707, P0706, P1702. It will randomly happen from time to time. Currently buying all the parts to replace the issue part and seeing if there’s a recall for said part

Truck started making a loud sound from engine compartment on startup after towing camper 150 miles. The sound started to get louder and started to notice exhaust smells in the cabin. I took the truck into dealer to find out that the exhaust manifolds were warped leaking on both sides of engine due to a stud being broken that holds the manifold in place the tech said it sounds like a diesel. The service advisor at the dealership said that it is a "common problem" on the 3.5L twin turbo engine. The cab of the truck fills with the exhaust fumes to the point where the driver gets headaches unless the windows are open. I asked if there was a recall on this problem and they said NO. The same manifolds was used for years on that motor, since then Ford redesigned the manifolds to use extra studs into the heads that are already there but now want the consumers to pay to install the new design to keep the fumes out of the cab. Looking online it seems to be a problem that the turbos are heating the manifolds to the point that they warp and snap the only stud used on the rear portion of manifolds for owners that tow with the truck (that has a tow package and rated at 12500 capacity) FYI I'm only towing 5000 pounds. My concerns are that the exhaust fumes can overcome the driver an cause them to pass out or become impaired by the carbon dioxide poisoning.

Erratic shifting of the transmission while driving. Dropped into lower gear causing me to skid on a wet surface. Luckily was only driving at 45 mph or it could have been worse or caused an accident.

The contact owns a 2015 Ford F-150. The contact stated that the rearview camera displayed a blank image while in reverse(R), and the message "Camera Unavailable" was displayed.

The contact arrived for the appointment and was informed that the recall was for the door latches and not the rearview camera. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

Transmission slips into third at high rate of speed exceeding 45 mph. Transmission will stay in third causing slow acceleration on turns.

Seems to be the same Lead Frame issues as previous years. Rough downshifts, flickering gear indicator on the screen, shuts off when in park (not safety related) for short term, fails to initially crank after previous unintended shut off.

For the past 3 days, I have had intermittent loss of steering from a power steering failure while driving on interstates/highways. Almost completely unable to steer it to safety on the side of the road. Ford has a recall(15S18), but I was told its vin-specific. My truck's vin does not fall under the recall, yet im having the same problems as the recall claims. Reaching out to see if this can be resolved and have a recall initiated. Thank you

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. Dealer Contact: Last September when this issue initially cropped up, the truck was taken to our Ford dealer for diagnosis. 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. Inspection: Truck has not been inspected by the manufacturer, only the dealer. Warning Lamps and Messages: "Hill Start Assist Not Available", "Service Advance Trac", "See Manual" (with a picture of a wrench)

Truck is at 135,000 miles and needs its 3rd oil pan due to faulty engineering. Ford is not covering repairs or offering assistance for previously repaired products. I bought truck certified pre-owned with extended warranty. The oil pan was cracked at that time and needed to be replaced at first service. On average oil pans are lasting less then 70,000 miles. How is this allowed to continue to occur.

Intake manifold actuator fails prematurely. Code P2007 and P2005

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.

Broken clock spring

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.

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.

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.

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.

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!

I noticed in the fall of 2024 that my transmission stared shifting hard between 30-40 mph during acceleration. I had the local Ford dealership check out the issue and they stated I needed a new transmission and included an estimate. I decided to seek information from 2 independent transmission shops and they could not confirm that I needed the transmission replaced at that time. The vehicle has been driving fine and I recently started to notice the hard shift again at 30 mph. Every once in a while, when the hard shift occurs, it seems like I lose power to the drive train and my vehicle slows down to about 15 mph and vehicles need to go around me. It only lasts for a few seconds and then the acceleration will continue to drive normal. I do notice an increase in RPM's from time to time as well while shifting around 30 mph but does not feel like it is slipping. Once through this area of shifting, the vehicle operates normally shifting through other gears. There were no warning lights or other symptoms leading to this issue. I did notice that there was an article posted with a possible transmission issue from this year vehicle that is being investigated concerning sudden down shifting while driving. Here is the article [XXX]. I am wondering if this is part of this issue? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
